Confused or Liberated?

Take Your Pick

alking the floor of the recent Embedded World show in Nuremberg, Germany, one was immediately struck by the vast number of small form factor computer modules on display. The advent of the Intel Atom and the VIA Nano families of processors has unleashed a firestorm of innovation and imitation among competing manufacturers. There were scads of established standards such as COM Express modules, newer emerging standards such as Pico-ITX and Qseven along with a large number of proprietary form factors featuring their own connectors and signal definitions.

Once again, this is evidence of profusion before the culling— the eruption of enthusiastic bidding for recognition and acceptance by the market before that market dons its black hood and selects those who will survive and those who will be returned to the humus of the Earth. The enthusiasm is understandable because these new computationally powerful yet extremely lowpower processors indicate that highly intelligent control can be embedded in ever smaller, ever more mobile applications, vastly multiplying the number of modules that can be sold, which results in cold cash in the till.

One of the challenges has been to optimize cost by finding the sweet spot for implementing the I/O, especially for applications with highly specialized I/O requirements. That was actually the rationale for the development of COM modules as opposed to single board computers (SBCs)—to separate the processor, which can be frequently upgraded, from the uniquely designed I/O subsystem, which is specific to the application and much less likely to be modified over time. Now the decision to go with a COM or an SBC depends very much on I/O requirements along with cost and volume considerations. That, however, appears about to change.

We are beginning to see the emergence of small form factor modules that can play the role of either COM or SBC, or which can be designed to be either on the same size board. Consider the recently developed Pico-ITX form factor. On a 100 x 70 mm board you find the Atom or VIA processor and memory along with a connection for external power and I/O that includes USB ports, graphics and Ethernet interfaces among others. There are also pin headers for

6

storage, etc. It is to date the smallest x86 SBC form factor.

But now we are seeing the appearance of the Pico-ITXe, which leaves off a number of I/O connectors but preserves the interfaces with pin headers and now incorporates the new SUMIT connectors, which give it the ability to plug into a stackable system with a specialized I/O card. Yet it still retains the properties of an SBC and can also act as a COM. A similar yet even more legacy-free approach is being taken in the new Industry Standard Module (ISM) specification coming out of the Small Form Factor SIG. This standard specifies basically the size of the board and the location of the mounting screw holes. It can be designed as a COM using the SUMIT connectors. In fact the first incarnation is called SUMIT-ISM. But a board built to the ISM spec is free to use only the SUMIT connectors, in which case it is a pure COM module. Or it can also include pin headers on board for other I/O, such as IDE, Ethernet, GPIO, etc., in which case by including an external power connector it becomes a hybrid SBC/COM. One could also imagine the same form factor supporting a pure SBC design. In the latter case, though, it would be easier to go with a PC/104 approach because the ISM’s 90 x 96 mm size is the same as PC/104.

What we no longer find in any of these implementations is a bus—no IDE or PCI. If you want to add modules, the serial interfaces in the SUMIT technology are available. If this seems a bit confusing, it is also very liberating for manufacturer and OEM alike. The same small form factor can fit into a vast array of small, general-purpose applications or into very small systems with special I/O needs. There appears to be a movement for manufacturers to seek partnerships with specialized design houses that can address the customer’s specific I/O needs while the vendor concentrates on the COM or SBC design most suited to those needs.

Here’s the best part—we’re not done, not by a long shot. Intel is expected to roll out its 32nm process technology sometime later in the year, a matter that is shrouded in secrecy. Will that lead to another round of smaller, even lower-power form factors?

Time will tell and it will be an exciting time to be sure.

Embedded COTS Vendors Issue Joint Statement on Open Standards Model and VSO Several leading COTS embedded board, subsystem and backplane and enclosure vendors, including Curtiss-Wright Controls, Elma Electronic, Carlo Gavazzi and X-ES Inc. have issued a joint statement of support for the proven open standard approach to the development of bus and board system architectures. The companies wish to reiterate and reinforce the importance of maintaining the integrity and openness of the VITA Standards Organization (VSO), an arm of the trade association of which each of the companies is a member.

The companies jointly issued the following statement: “The cooperative work of the members of the VITA Standards Organization (VSO) resulted in the creation and evolution of VME, for over 25 years the de facto board architecture of choice for the aerospace and defense market, and, more recently, VPX (VITA 46/48), a higher performance, more flexible enhancement to VME. The spirit of ‘coopetition’ and openness that brought VSO’s members, including competing vendors and users, together for the common good of the industry reflects and embodies the standards body’s basic principles that ensure fairness, inclusion and consensus for all participants. These principles have fostered and guided the success of VITA since its inception in 1984, then under the stewardship of VITA’s founding director Lyman C. Hevle, and the VSO, one of the electronics industry’s most respected standards body, since its formation in 1993.

“We recognize the importance of defining an open specification for system-level VPX interoperability, but we also believe that this work is best done within the existing, proven model of the VSO Working Group system. The open forum provided by VITA is the right and best place for the industry to cooperatively develop the critical new VPX initiatives destined for use by important customers such as the U.S. military.

“We recommend the formation of a VSO Working Group on VPX interoperability for VITA 46 (VPX) to help resolve issues and speed the development of a common VPX backplane architecture while ensuring that no single company or selective group of companies is able to exert undo influence on the specification and unfairly benefit from the cooperative work of all the member companies who have contributed resources and efforts over many years to the standard’s development.”

The VSO’s fundamental principle, as stated on VITA’s Web site is: “Within the VSO no one individual holds the power to decide what technology may become a standard—that power belongs solely to the membership.” The joint statement above is made in the spirit of this principle.

BittWare Adopts VITA 57 FPGA Mezzanine Card Standard

BittWare has announced it has adopted the VITA 57 FPGA Mezzanine Card (FMC) standard on their new “S4” family of boardlevel signal processing solutions.

FMC provides an industry standard for expanding processing or I/O via mezzanine cards that connect to FPGA(s) on the carrier card. Electrically, the FMC connector supports high-speed serial (SerDes) ports, LVDS, clocks and single ended signaling, providing a wide range of options and flexibility to the user.

Similarly, the mechanical format of the FMC supports a variety of standard carrier board formats including AdvancedMC (AMC), VME, VXS and VPX, and can be air-cooled or conduction-cooled.

The addition of an FMC site on BittWare’s S4 family of FPGA boards, based on Altera Corporation’s 40nm Stratix IV FPGAs, allows customers to support an extremely broad range of applications simply by adding specific I/O or processing via various FMCs. Coupled with BittWare’s ATLANTiS FrameWork (AFW) for FPGAs, the FMCs also fa-

cilitate design reuse of FPGA implementations that will decrease time-to-market, while also lowering costs across multiple programs. In addition to supporting VITA 57 on their S4 family of signal processing hardware, BittWare will also be releasing their own family of FMCs for I/O and processing expansion.

At the heart of the S4 family of signal processing hardware is an Altera Stratix IV GX FPGA, which provides unparalleled performance and flexibility.

Each onboard FPGA supports 530K equivalent logic elements, 20.3 Mbits of RAM and 1,024

embedded multipliers. Onboard connections to the FPGA also provide up to 27 full-duplex, multi-gigabit transceivers—24 of which support data rate speeds of 8.5 Gbits/s. The FPGA supports a number of protocols, including PCI Express Gen1 and Gen2 and Serial RapidIO.

CP-TA Releases New Standard Interoperability Guidelines for ATCA

The Communications Platforms Trade Association (CPTA), an association of communications platform and building block providers, has announced the release of its new interoperability documents, the Interoperability Compliance Document (ICD) 3.0 and the Test Procedure Manual (TPM) 3.0. The documents outline industry-standard interoperability criteria and testing procedures for AdvancedTCA (ATCA) building blocks. The new versions are mapped directly to the PICMG 3.0 Revision 3.0 ATCA Base Specification, which was completed last year.

CP-TA completed a proofof-concept demonstration using the TPM and ICD documents and corresponding test tools to integrate building blocks for an IPTV system in one-quarter the time it took to integrate non-tested building blocks for the same system configuration. Among the many enhancements, the documents have been simplified to structure test procedures on a one-to-one basis directly with the structure of the PICMG 3.0 Revision 3.0 specification. Additionally, requirements that are not found in the governing specification have been removed, and several requirements that were previously ambiguous have been clarified. The included mandatory test cases will help system integrators identify what they must

Industry Insider do in order to pass an integration project for interoperability. Each test procedure is described in detail and mapped with the requirement numbers in the PICMG specification.

Machine Vision to Increase Productivity and Lower Costs of Solar Cells

Dalsa Corporation, which specializes in machine vision technology, has announced its entrance into the solar cell inspection market. The company’s experience in area scan, line scan and embedded processing for inspection in the flat-panel display industry are now being applied to solar cell inspection, resulting in high-quality, yet cost-effective inspection capabilities for the solar cell industry. Machine vision is used for three general purposes by solar cell manufacturers: product inspection, identification and tracking, and lastly, product assembly. Dalsa’s cameras and hardware are used in the initial part of the quality inspection process to verify patterns and edges, inspect coatings and to check for micro-cracks.

The precision of the image capture and processing technology contributes to the immediate and accurate detection of defects in this critical stage of the manufacturing process.

Solar cell manufacturers are under pressure to drive down costs in order to achieve “grid parity,” the point at which the cost of solar energy is roughly equivalent to the cost of conventional power distributed on electric grids. Analysts forecast that this may occur in 2011 as module prices continue to drop.

Dalsa’s new capabilities in line scan, area scan and embedded processing include time delay integration (TDI) technology that is accurate in identifying defects and efficient in delivering fast im-

age capture (110 KHz), resulting in improved yields and reduced costs. In addition, CMOS sensor technology enables 62 frames per second with 4 megapixel resolution, for greater system throughput along with a higher resolution with a camera that allows image capture of a solar cell down to 40um with one shot by utilizing its 22 megapixels, with low dark current, low noise and higher dynamic range than any competitive product.

RTS and RadiSys Partner on Integration of Real-Time Hypervisor for Multicore

RadiSys and Real-Time Systems have entered into an OEM agreement under which they will jointly develop and integrate solutions for RadiSys embedded system products using Real-Time Systems’ Hypervisor, which will be used to improve performance supporting Microware OS-9 as well as other RTOSs and Linux and Windows XP. The RTS Hypervisor leverages Intel’s Virtualization Technology (VT) by partitioning processor resources—core, memory and I/O devices into what amount to individual, independent computers on a single multicore device. The RTC Hypervisor concentrates on reducing system overhead to maintain real-time performance of the RTOS running on one core while Windows XP or Linux run on another core in parallel. The Hypervisor also facilitates data communication between the two OSs without compromising the real-time performance of the RTOS. It is also possible to execute multiple copies of the same or different operating systems, such as multiple copies of an RTOS along with a single copy of a general-purpose operating system, depending on the number of cores available.

RTI and Tresys Partner to Enable Highly Secure Data Distribution

Real-Time Innovations (RTI) and Tresys Technology have announced a partnership to offer integrated technologies and services for incorporating security into high-performance distributed applications. The partnership implements a reference security policy to demonstrate using Security-Enhanced Linux (SELinux) to protect distributed applications that use RTI Data Distribution Service for integration or inter-process communication. Due to the unique and highly customized nature of distributed architectures, the companies have combined their expertise to offer a joint Security Architecture Assessment for tailoring the profile to specific system requirements.

The joint Security Architecture Assessment extends both companies’ prior, independent offerings. Tresys provides strategic guidance to assist system architects, developers and integrators in choosing and applying the latest security technologies. Similarly, RTI offers an architecture study that provides a RTI expert that works with the development team to identify its application requirements and use cases, then helps design a suitable architecture to best meet the objectives and performance requirements of the distributed system. The new combined service addresses the design of distributed real-time systems with security technology designed from the start.

by VDC Research Group. Growth of the merchant AMC board market is projected to be relatively flat through 2010, before significant growth is expected in 2011 and 2012.

In the report, VDC identifies that so far AMC board shipments have been driven primarily by the consumption of AMC boards as mezzanines in ATCA systems. The development of the MicroTCA market—the original proposed driver of AMC—is projected to be delayed by the current global recession. However, it is expected that the MicroTCA market will grow at a healthy clip following the downturn, with significant revenue shipments of MicroTCA systems being achieved in the 2011-2012 timeframe. At that time it is projected that a significant portion of the AMC board consumption will be as blades in MicroTCA systems.

The study also revealed that although significant volume growth was not expected in 2009, evaluation activity—including OEMs analyzing AMC displacement of existing merchant and custom solutions in a number of applications—was picking up. Indeed, 2009 evaluation and pilot performance may be a material indicator of 2010 and 2011 shipment revenue.

AMC Boards Driven by ATCA Today, MicroTCA in 2011

Merchant AMC boards revenues are expected to nearly double during the next three years according to a recent research report released on the xTCA market April 2009

SMALL FORM FACTOR FORUM

The Embedded Smart Car: USB

O

ne of my favorite possessions is my 1997 Firebird TransAm. It is red and very fast with a big V8, a six speed, racing tires and heavy-duty suspension. When the T-top is open, you can accelerate into third and hear the gas guzzling into the cylinders while simultaneously feeling the wind pulling back your face and hair. But now it sits in my garage because it is impractical to drive with its 10-miles-per-gallon appetite. Although I can’t bear to part with it, I ponder its future in a world of “smart cars.”

I am struck by the parallel between this TransAm and today’s design of industrial control systems. It has been the tendency when designing industrial control systems to include all the bells and whistles from LCDs to desk-top software to unlimited power running 24/7. Going forward, it is difficult to justify this powergreedy, dedicated single-board PC for tasks such as controlling a few lines of digital I/O, measuring some A/D or doing some data logging. Once the total cost of initial hardware plus operating expenses for a year is calculated, it becomes clear that this is not viable either financially or environmentally. More importantly, technology has progressed to the point where there are so many more choices for elegant and efficient ways to implement control systems, that the “muscle-car” approach to embedded systems is becoming less relevant. Enter the ubiquitous USB. USB is a serial communication channel stacked with market advantages including multiple channels per CPU chip set, comparable or faster speeds than the old blue collar PC/104 ISA bus, availability in Host or Device mode, and support on x86 platforms, ARMs and microcontrollers. By itself this doesn’t necessarily save energy or ease system designs, but what it does do is act as an enabler to reach such a goal, rather like the smaller cars inching their way into the market at a time when gas shortages are forcing fuel prices up and long lines are making small cars attractive.

At the same time USB is making deep inroads into systems everywhere, another phenomenon is taking place: cheap processor intelligence is being built into virtually every controller chip released today. This runs the gamut from sensors to communication chips to A/D and D/A chips to power chips to microcontrollers.

Compare this to just a few years back when nothing had built-in

10

April 2009

intelligence and “bit banging” was the term of the day. A 12” x 12” controller board has been shrunk into a single chip solution with USB, I2C, or SPI output! These chips are ready to roll. Remember how smaller engines made compact cars more viable?

And perhaps more important than all of these hardware advancements is the growing number of software options available to system designers today. Not surprisingly, USB support is included in an overwhelming number of them. So, gone are the days when DOS was the only inexpensive OS for an embedded system, thereby mandating an x86 platform. Today, there are ample software platforms supporting USB for ARMs and microcontrollers as well as traditional PC-based systems. The accompanying development tool chains are readily available, often free to download and certainly easier to use. This trend results in more and more simple device-side I/O controllers outputting USB, I2C, or SPI, while the Host is operating under another OS altogether. Distributed control, which was once the more complicated option, is becoming easier than shoehorning control onto single board computers that need complicated, custom drivers for each operating system to make applications run.

So, if we pause a moment, step back from our current project and look at the big picture, it takes only a couple of moments to realize we are on the brink of some radical changes in the implementation of traditionally blue collar control system or PC/104type embedded system. The impetus to change or upgrade legacy systems will be driven not from a need for additional performance, but rather from a need to reduce operating costs and conserve energy, which is possible when we maximize the newer, more efficient technology that is at our fingertips.

These are exciting times. Are we ready to head down this road?

You bet we are. Ladies and gentlemen, start your engines!

Green Engineering

Green Engineering Offers Huge Opportunities for Embedded Systems Technology has brought the energy consumption of computer systems down dramatically.

Now it is time to apply computer intelligence to reducing the world’s energy consumption and its effects on the environment.

by T om Williams, Editor-in-Chief

A

n incredibly vast amount of the power that is produced worldwide is simply wasted, dissipated as heat, gone. At the same time the emissions from the fuels that created that wasted energy are dissipated into the atmosphere as greenhouse gases, which worsen global warming. Energy waste happens at the macro level at power plants and over longdistance transmission lines as well as at the micro level in millions of individual appliances and devices. The vast majority of systems and devices that consume energy today also contain embedded processors for control, monitoring and network communications. This presents a huge opportunity for the engineers and programmers who understand these devices to make them more energy efficient by applying the same engineering disciplines used to develop them in the first place.

The real challenge and the real opportunities lie in using this computing power to improve energy savings outside the information and communications industries in areas including industrial manufacturing, transportation systems, building automation for retrofit and design, power and energy management and more. Industrial

The largest amount of power used in factories is for running electric motors. Many machines consist of multiple motors of different power capacities, all of which can benefit from intelligent control.

activity alone is responsible for some 23 percent of the world’s greenhouse gas emissions—and that is beyond the contribution of the power plants that gener-

ate the electricity used by industry, which uses nearly half the electrical power generated globally. There is much to do and now we have the means to do it.

Technology In Context

Green is not just a term for use by environmental activists. It is also the color of money. It directly affects the bottom line. What CEO would object to running his company’s operations and even expanding them while using and paying for less electricity? Who would oppose making better use of engineering and human resources and improving not only the automated systems, but also the overall production process by automating operations around a common computing architecture that reached from the corporate servers to the sensors and actuators on the factory floor? And if that had the added benefit of reducing emissions in the face of government restrictions that are surely on their way, the payoff would be even greater.

But for real, raw energy savings in the manufacturing environment, we need to address the use of electric motors.

While industrial activity uses nearly half the power generated globally, industrial motor systems consume about 65% of the electricity used in factories, making them directly responsible for 7% of global emissions and representing a huge portion of the expenses for the manufacturing process.

Managing Motors

Most motor systems simply turn on and off and run at the speed and torque they were designed for. However, applications have varying needs and while a minority may be fine with a dumb motor, most could take advantage of intelligent control to match the speed and torque of the motor to the load at any given time. There are also issues with inrush current when a motor starts up because it draws a lot of current to get going. For applications that require motors to frequently start and stop, this can amount to a huge waste of power.

Dumb motors that simply churn out a constant power output are often matched to the needs of their applications by mechanical means such as gears and belts resulting in further huge wastes of power.

One approach has been the variable speed drive (VSD), a motor controller that holds a motor’s velocity signal to a selected range based on a function of voltage, temperature and load changes. Two types are available: an open loop control that simply sets the speed and relies on the motor’s in-

limit the current inrush on start-up, which is often a significant spike in current, letting the motor ramp up more slowly to the desired speed and torque, and directly affecting the bottom line on the power bill.

In fact some estimates find that properly sized motors (many are larger than needed because designers overcompensate) with proper intelligent control, along with improved gears, drives, bearings, lubricants, etc., could use 60% less energy.

ternal regulation, and a more intelligent closed loop control that measures the motor’s speed and adjusts it to the set value.

Most VSDs are external boxes that attach to the motor and operate in the range of 75 to 750 watts. But with advances in smaller, low-power CPUs, the path is being opened for integration into even smaller motors (as well as larger ones) and the incorporation of additional intelligence for even more efficient operation.

This represents a growing opportunity for implementing control using embedded intelligence, which offers even more possibilities in that an intelligent motor controller can dynamically monitor the motor’s load as the load changes and calculate the amount of power needed at any given time, and adjust the power accordingly.

This fine-grained control not only greatly reduces the overall amount of electricity used; it also can increase the life span of a motor by reducing maintenance requirements and—not insignificantly—reducing the carbon footprint of the motor.

That same embedded computing power can also be applied to cases where a motor does not need to start up at full voltage and torque. Intelligent controls can

The next generation of green vehicles will also heavily rely on embedded intelligence—not only for their internal operations, but also in terms of the infrastructure that will support them. The coming wave of pluggable hybrid electric vehicles (PHEVs) and fully electric vehicles will interact with the Smart Grid and with intelligent networks of charging stations and battery exchange facilities, all of which will be automated. When a pluggable vehicle, be it PHEV or full electric, connects to a charging station, that station must identify the vehicle by means of an RFID chip for billing purposes and transmit the data to a central location. Intelligence on board the vehicle must not only control the interaction between gasoline and electric motor and/or control the electric motor; it must also monitor available energy and be able to locate a charging station or a battery exchange station via a GPS system and alert the driver.

Work is now underway in Denmark and Israel—supported by government funds and tax incentives—to install a nationwide infrastructure for the use of allelectric vehicles. The system consists of intelligent charging stations and battery exchange stations. For vehicles with replaceable batteries, the exchange stations are a network of bays that the driver can pull into, have his car identified, and where a robot arm will replace the car’s battery with a fully charged one in less time than it takes to fill a tank with liquid fuel. Such a system will have its own complement of embedded intelligence, but will also have to interact with the overall electrical power grid.

Green Buildings: Big Savings and Better Living

Commercial and residential buildings are major conduits for venting energy into space in the process of providing shelter, warmth and comfort. In 2020, the world will emit some 11.7 billion tons of CO2 amounting to about $340 billion because of inefficient buildings. The losses are

14

due to leaks in window and door seals, faulty insulation and poor window design to name a few causes. But they also result from inefficient energy usage in terms of heating ventilation and air conditioning (HVAC), lighting and water heating.

In the U.S. the Green Building Council has established a building rating system called Leadership in Energy and Environmental Designs (LEED) to rate new building construction and existing building retrofit for energy usage and environmental quality. The LEED system specifies certification criteria for site sustainability, water efficiency, energy and atmosphere, materials and resources and for indoor environmental quality. While a number of these can be addressed in the building’s design and construction, an important part of the criteria concerns the building’s energy systems. As in so many other green applications, optimization of energy usage in buildings requires accurate distributed sensing and control in the form of a building management system (BMS). Another part of the criteria actually evaluates the controllability of the systems used to monitor and control lighting and thermal comfort With a BMS, for example, it is possible to set up multiple policies for lighting control based on the types and usage of different rooms. Sensors can detect if the rooms are occupied and when not, shut off the lighting. A combination of temperature and CO2 sensors makes it possible to adjust the heating or cooling and optimize the airflow for maximum comfort with minimal expenditure of energy.

For optimizing ventilation, software in the BMS must be able to work with controllers for the efficient speed control of pumps and fans. Once again, we see how the importance of intelligent motor control plays a central role in the reduction of electricity consumption in so many diverse applications. A BMS must be able to deal with switching large loads in big facilities as well as having the ability to interface with legacy sensors and devices in the case of a building retrofit. Networking capabilities must span the IP network, wireless networks and the ability to interface with field buses, as we saw in the scenario of the factory.

Power Management—the Roots of Green

While a great deal of savings can be realized in terms of how energy is used and consumed, even greater potentials lie in how it is produced and distributed. Production and consumption cannot really be separated. They are interconnected and optimizing them both is required to reduce emissions and the waste of electricity in the realization of the Smart Grid. The goal is to make the grid more reliable, more “visible,” more efficient and more interactive to accommodate the new sources of renewable energy, such as wind, solar and geothermal, that will be coming online in the near future. Department of Energy estimates show that a mere 5% increase in overall efficiency of the country’s power distribution systems would be the equivalent of eliminating the fuel and greenhouse gas emissions of 53 million cars.

Among the attributes of the Smart Grid are that it will be more interactive in terms of two-way communication and that it will be more visible, allowing operators to easily view problems and outages and oversee usage to respond more quickly to changes in demand. One of the attributes of the Smart Grid will be the development of the Advanced Metering Infrastructure (AMI) whereby meters will measure and record usage data at a minimum in hourly intervals. This data will be available to both the utility and to customers at least once a day. Another feature that is starting to appear already is automated meter reading (AMR) where meters are networked, often using the wireless ZigBee protocol to send usage data to the utility for billing, eliminating the need for meter readers to visit customer sites each month.

The existence of the AMI will make it possible for customers to manage their usage by taking advantage of the timeof-use pricing, i.e., lower prices for offpeak usage, to set smart appliances such as dishwashers, washers and driers to operate when they receive the signals over the power line from the utility that the rates are at the pre-programmed level. Smart appliances, of course, will be equipped with microprocessor-based

Technology In Context

modules to allow them to communicate with and manage their usage of the Smart Grid.

The open, two-way architecture that enables the AMI will also empower grid operators to use visualization technology for real-time load monitoring and response to shifting demands.

One prototype management system, under development at Oak Ridge National Laboratory, integrates real-time sensor data, weather information and grid modeling with geographical data so that an operator can view the grid layered on top of Google Earth from the national level on down to the street level to pinpoint problems and gain insight into operations.

As the grid becomes more intelligent and as more sources of renewable energy become available, it also becomes more decentralized. One of the major areas of power loss is transmission over long distances from power plants to substations and on to consumers. The increased use of solar arrays, wind generators and other renewable resources require that they be easily integrated into the intelligent grid.

As solar panels spread among the rooftops of both residential and commercial buildings, they will be taking power off the grid when needed and pushing power back onto the grid (“running the meter backwards�) when they are producing more than is being used at that location.

This requires the use of intelligent grid tie inverters.

A grid tie inverter works like a normal inverter in that it chops up the DC voltage into a square wave and then smoothes it into a sine wave to produce AC voltage. The grid tie inverter does this, but also has the intelligence to match its frequency to the phase of the grid. It also adjusts its voltage to be slightly higher than that of the grid so that it can make its current flow onto the grid when needed. Grid tie inverters use an embedded computer to sense the grid’s AC waveform and match it as well as to set their output voltage to work with the grid. Wind generators, like solar arrays, will also increasingly connect to the Smart Grid from decentralized locations and from locations that may not be fore-

seen from a long-term planning perspective. They therefore also need this match of intelligence to the grid to be able to connect cleanly. They will require the familiar intelligent control of output voltage and current and matching their AC to the phase of the grid.

The new generation of green energy will save consumers and industry enormous amounts of money and at the same

time contribute to the reduction of greenhouse gases that are the major source of accelerating climate change. Indispensible to this effort is the integration of embedded monitoring and control for what can be a huge environmental and economic opportunity.

The following case studies demonstrate green engineering in the application areas of renewable wind energy generation and energy consumption optimization in commercial and industrial air-conditioning systems.

real-world behavior. Armed with the data, designers can achieve the desired solution by improving system components or creating the next generation of products. In other words, measure it and fix it. Common measurements used in green engineering include power quality and consumption; vehicle and factory emissions, such as mercury and nitrogen oxides; and environmental parameters, including carbon, temperature and water quality.

Opportunities and Key Technologies

For those considering joining the green dream, two pointed questions appear at the top of their minds: is today’s technology viable enough to make an impact, and is this really a sustainable business opportunity? The good news is that many engineers have traveled down this path before. In addition, significant innovations in measurement, automation and design tools have made the technology components for green engineering not only easier to use, but also cheaper to acquire than before. Key technologies that enable green engineering include: • High-speed and high-resolution measurements

18

April 2009

• Domain-specific analysis libraries • FPGAs for advanced control • Graphical programming to measure and implement control Some of these new technologies have resulted from the growth in the semiconductor business, which has led both to advances in the capabilities of analog-to-digital converters as well as decreased costs from the mass adoption of consumer electronics. Furthermore, new enhancements to existing design and engineering tools, such as graphical programming, have made them more accessible to domain experts rather than solely technology experts. By shifting the necessary technology directly into the hands of those who are closest to the problems, solutions can be implemented more quickly and more effectively than in the past.

Green engineering solutions span almost every market, ranging from the rapid advancement of environmentally friendly products, to the study of climate changes, to the development of sustainable renewable energy such as wind power and biofuels. Industrial applications, traditionally viewed as environmentally unfriendly, are also ideal for green engineering when one

Renewable power generation covers a wide range of technologies, including wind, solar (photovoltaic and thermal), biomass, geothermal, hydro, wave and even highenergy physics. Research and development in these areas are exploding around the world, driven by energy prices, government legislation and incentives for commercialization. More than 50 countries from a wide variety of political, geographical and economic backgrounds have set aggressive targets for the amount of energy generated from renewable sources (Table 1).

The latest global status reports state that clean energy technology supplies approximately 5 percent of the world’s total energy consumption. With government mandates of up to 60 percent and deadlines as early as 2010, engineers and scientists are rising to meet this daunting challenge at a worldwide scope, with an increasingly focused drive these recent years.

Wind energy is one of the fastest emerging areas, growing at a rate of 30 percent each year with an installation of more than 100 gigawatts. However, this industry has several key challenges to conquer before gaining acceptance as a mainstream energy supplier. For example, wind turbine manufacturers must scale up difficult processes to meet the increasing demand, such as automating manufacturing and test systems for components such as blades, generators and gearboxes. Plus, hardware-in-the-loop (HIL) simulations of the wind turbine’s mechanical and electrical properties are used to predict its behavior during variable wind conditions, and advanced control systems running the pitch/yaw drives help maintain a constant rotating speed while reducing damage

on the turbine components during high winds. Then, during the actual execution of the wind turbine, all types of sensors, signal processing and data analysis are also needed to perform machine condition monitoring, power quality monitoring and structural health monitoring.

One factor out of the many involved in designing and implementing these large wind turbines involves minimizing their acoustic emissions to comply with the government noise standards. Engineers must optimize the wind farm layout while factoring in meteorological conditions and terrain to minimize the noise impact on the surrounding community.

DELTA, located in Hørsholm, Denmark, has developed a custom measurement system for wind turbine noise testing to help engineers design wind farms by supplying data for predictions (Figure 1). This system uses a National Instruments (NI) PXI system with dynamic signal acquisition modules to acquire acoustic data from a microphone at the required frequencies.

The tests call for measurements of sound power level, one-third octave band levels, and tonality at wind speeds from 6 to 10 m/s. DELTA also developed their noiseLAB software using NI LabVIEW graphical programming, which allows for monitoring of the measurement data in real time and then provides a preliminary analysis immediately after the acquisition.

All data is stored with high resolution, thus facilitating supplementary analyses.

Machine and Process Optimization

In the industrial and automation world, most applications are solved with traditional tools such as simple low-cost PLCs. However, systems are growing in complexity as engineers look for additional ways to optimize control and reduce wasted resources. These applications relentlessly push the capabilities of traditional systems, requiring higher loop rates, advanced control algorithms, more analog capabilities and better integration with the enterprise network. Programmable Automation Controllers (PACs) were introduced to meet these measurement and control needs, combining the powerful functionality of a PC with the ruggedness and reliability of a PLC.

Renewable energy goals set by various governments around the world.

In their “Programmable Logic Controllers Worldwide Outlook” study, Automation Research Corporation (ARC) identified five main PAC features, characterizing the functionality of the controller by defining the software capabilities. Because PACs are designed for more advanced applications, the software platform should have multi-domain functionality capable of combining motion, process, control and communication functions in the same logic environment. These functions should be seamlessly integrated into a single package, instead of existing as disparate software tools that work poorly with each other.

Furthermore, since all industrial applications require significant customization, the open and modular architecture of PAC hardware and software allows engineers to pick and choose the appropriate components for their design.

To help simplify the system design, the use of high-level graphical development tools allows for easy translation between the engineer’s concept of the process into code that actually controls the machines.

To address the needs of custom industrial applications, National Instruments offers a family of PAC deployment platforms combined with the LabVIEW graphical programming environment.

Chiller Energy Management System (CEMS) Engineering decided to use NI PACs in a green engineering application that involves improving and optimizing current systems used at work and in daily life. This Malaysian-based company specializes in energy management of largescale, climate-controlled commercial and industrial facilities.

Centralized air-conditioning systems for large areas traditionally consist

of multiple chillers that control air temperature by removing heat from a coolant liquid through vapor-compression or an absorption-refrigeration cycle. However, their default settings are typically not optimized for specific environments, such as the high heat and humidity of Southeast Asia. CEMS Engineering used NI tools, including programmable automation controllers (PAC) and LabVIEW, to acquire real-time input data directly from sensors on the chillers that was then processed to send new operating instructions to the chillers. These operating instructions are determined through a series of variance calculations of the realtime input data, proportional integral derivative (PID) control loops, principles of thermodynamics, heat transfer and advanced mathematical optimization, and other proprietary equations, resulting in reduced electricity bills and energy consumption up to 30 percent. Implementation of the CEMS Engineering system was completed within six months of commencement and is now installed and running at customer sites.

As the environmental and energy challenges of the world become more acute, innovative engineers and scientists must step up to measure and fix the world around them. Green applications will be the engineering and technology focus for the next five to ten years, and thus advances in green engineering will continue to empower researchers and developers to both solve complex environmental issues and improve their products and processes.

ireless-enabled data services have never been more important to business success. For more than 20 years, businesses have used wireless data to improve services and enhance the value of customer offerings. Fast forward to today. Carriers are now connecting the next generation of “wireless-enabled” devices beyond cell phones or laptops.

Simultaneously, hardware manufacturers are embedding wireless capability into a wide variety of devices for numerous business and consumer applications. Robust commercial—primarily digital cellular—data networks are in place and are being used to connect increasing numbers of networked devices.

Most major carriers have opened their networks to machine-to-machine (M2M) communications, which is the idea that machines or objects can be readable, recognizable, locatable and controllable via wireless networks. Also talked about as “embedded wireless” or the “Internet of Things,” the M2M market is helping businesses improve efficiencies, automate processes, deliver ROI and reduce overall operating costs.

The market has been growing rapidly in recent years as a number of vertical industries recognize the need for efficiency and improvements. No longer primarily focused on telemetry, M2M now enables innovative services such as automated “smart homes,” real-time asset and people loca-

Technology In Context

In fact, M2M uses wireless networking to communicate in real time with sensors embedded just about everywhere, and is enabling organizations worldwide to save energy, water and natural resources, create efficiencies and boost revenues.

Solutions providers in a variety of industries such as resource management, utilities, the public sector and agriculture can develop and implement profitable M2M green applications.

Some Real-World Examples

Trash Management: Instead of hauling trash, companies can better manage their trash by determining the best way to handle the waste and scrap coming out of their businesses. With devices installed on or near a trash compactor control panel, companies can record and analyze compactor activity, energy use, safety door switches and pickup and return. From there, the collected data can be wirelessly relayed from any location. This helps reduce costs and environmental impact of trash.

For example, American Trash Management implemented a wireless M2M solution that relies on remote sensors to monitor containers, send notifications, and receive and process usage information. This data is then uploaded to a centralized business management system for highly effective and scalable waste management. With increased scheduling efficiencies and optimized truck rolls for fuel

and maintenance savings, this has yielded both cost savings and increased customer satisfaction.

Water Management: Advanced wireless water management devices can monitor irrigation schedules and water usage like never before, to provide just the right amount of water to keep landscapes healthy. Such a system can calculate and control irrigation on a “just-in-time� basis, using real-time data from weather forecasts and just-passed weather events, water evaporation, plant transpiration and sub-soil leakage. Many organizations,

including the State of California, better regulate their water usage levels and irrigation schedules using M2M. One example of a wireless water management system uses a communication and interrupt device that attaches to an existing irrigation system and records and adjusts the irrigation watering times. The manager device also records runtimes, cycles, start times and other irrigation operating data, which it transmits back to the data center over a cellular telephone network where it is accessible to the customer over the Internet (Figure 2).

Smart Grid Monitoring: A large electric utility in Arizona is at the forefront of a growing national trend toward smart metering. Their Automated Metering Infrastructure (AMI) deployment consists of M2M data communications to and from electric meters at customer premises. In practice, the AMI simultaneously provides a higher level of service and reduces many hard and soft operational costs required for service.

Consumers can monitor electrical usage in real time, while the utility can identify and correct service interruptions more quickly, and improve efficiencies in the meter reading process, billing and customer-service operations as a whole. The meter data is backhauled across the machine-to-machine (M2M) wireless network within a secure IP VPN. As a result, the utility eliminates approximately 7,200 truck rolls per month for every 100,000 meters deployed, yield-

ing a substantial direct savings, customer satisfaction improvement and carbon footprint reduction.

But these examples barely scratch the surface of the potential for innovative networked applications. Within a few years, hundreds of millions of wireless devices will be attached to digital cellular networks, quietly performing the things we want them to do in our quest to be more cost-efficient, safer and more responsive to our customers. And it doesn’t stop there—regulatory initiatives will drive adoption of wireless-based data gathering and remote control applications in the environmental, energy and safety arenas. For all of these reasons, the M2M market grew strong over the course of 2007-8, and is ideally positioned to continue this growth over the next five years.

Looking Ahead

Which applications will evolve? How will they impact our lives? And how will organizations embrace these capabilities as essential to both future productivity and competitive success?

M2M services are similar in some ways to cellular or Internet services. However, instead of phones and PDAs making calls, sending emails or texts, or surfing the “net,” M2M sensors, or intelligent “black box” devices, are equipped with cellular radio-based modules that collect information from remote locations and transmit it to a central location. This is similar to how remote PCs and laptops connect to the servers in a company’s IT department.

M2M communications are conducted via broadband/wireless connections in order to access and process the gathered data.

The essential difference with M2M is that on their own, with no human intervention, compactly packaged remote devices “sense” changes in location, movement, temperature and the like, then issue an alert and transmit important data about specific events.

The ability to monitor and control electrical power systems, water, oil and gas networks provides the utility industry with a more cost-effective way to measure utilization (in real time or scheduled), the ability to manage supply and demand more effectively, and to an-

ticipate, identify and fix problems more completely and rapidly. The cost savings associated with measuring utilization and providing maintenance functions are tangible, and not simply when meters and other network elements are in remote or hard-to-reach locations. For instance, as “First Time Fix” is improved, utilities can eliminate the former process of iterations of “Fix and Wait.” In other words, fix what you can see, and wait to hear if it still isn’t working or if there is more to fix elsewhere.

Harbor Research has described the effects of M2M networking as “Pervasive Intelligence”—allowing businesses to make immediate decisions based on accurate, real-time data from near and far-flung portions of their infrastructures. However, the market is broadening to also include the use of wireless networks to connect specialized devices in a variety of new businesses, from retail outlets and fast-food restaurants to major production and business facilities. M2M is increasingly used for remote monitoring of environmental conditions (at land-

fills for example), for industrial monitoring of chemical containers, pipeline status and capacity management, alerting operators to dangerous conditions as well as reducing maintenance costs and increasing the reliability of systems and services delivery.

The emergence of M2M is continuously changing the face of industry by allowing for improved business applications and automation. Wireless sensing and tracking technology is real and is driving innovation across numerous sectors.

Integrating these M2M capabilities and solutions enables automated processes to streamline operational costs, improve customer service and create new service offerings like never before. These are all factors that can enhance an organization’s ability to remain highly competitive and realize additional revenues in today’s challenging economy.

omputer-on-module (COM) manufacturers are delighted that their pluggable module alternatives to conventional single board computers (SBCs) are getting attention beyond the high-volume gaming and kiosk-type applications for which they were initially well suited.

The concept of a small CPU core on a standardized module sounds simple.

The carrier board provides power, and the COM contains the processor and chipset that already provide built-in buses and I/O back to the carrier. Conversely, SBCs bring I/O to pin headers and expansion buses to standardized interfaces like PC/104.

So consolidating all of these signals into high-density surface-mount board-toboard connectors seems like just a logical extension of the other architecture.

Unfortunately, the resemblance ends right there. For starters, buses and I/O are well-defined, but carrier design considerations must include logic levels (5V, 3.3V, 2.5V, etc.), terminations and pull-ups. The major problem is that instead of the case where SBCs have power supplies on board that meet the voltage and current requirements of the CPU and chipset residing on the same board, a COM requires each application-specific carrier board to satisfy its CPU and chipset power requirements on a different board. Worse still, “blackbox” modules are designed with varying bulk capacitance, power sequencing, and Advanced Configuration and Power Interface (ACPI) power management support.

In order for a COM Express module to function properly, the entire interface must be terminated with proper signals, timing, sequencing and circuits (Figure 2). Suddenly, designing a carrier board resembles a 9-inning ball game. If the engineer can’t get the carrier to operate with the first vendor’s module, another round is necessary, quickly becoming a twilight double-header. Whether designing inhouse or farming out to a design services company, OEMs counting on multi-sourcing are wise to confirm interoperability early in the design phase.

Releasing a system to production with only one module validated can lead to unpleasant surprises later when the purchasing manager needs an emergency second source due to supplier delivery or quality issues. Too often, the next vendor’s module won’t boot, and there are many possible reasons why. The designer is locked in the clubhouse without any visibility, and the BIOS and OS offer few clues about where the replacement “black box” module hangs.

The interoperability problems are well documented in the COM vendor community. Often, the vendors create straightforward implementations to the module standards only to have customers encounter interoperability issues. The situation transcends any one vendor, so it has been bounced back to Spring Training for the originating trade groups to sort out.

Responding to calls for help, two groups are tackling the obstacle to growth head-on: PICMG and SFF-SIG (Small Form Factor Special Interest Group).

PICMG’s approach must work within the confines of the existing COM Express specification, to minimize disruption to the growing market for legacy-free COM Express modules. SFF-SIG approaches the challenge with a ground-up new architecture that is both legacy-friendly and forward-looking to USB 3.0 and PCI Express 2.0.

The PICMG organization has completed a year-long task of generating a large document called the Carrier Design Guide (CDG). The CDG contains reference circuits and detailed explanations to help OEMs and design services companies implement typical peripherals on the application-specific carrier board designs. PC architecture buses such as

Figure 3

COMIT’s scorecard of features.

PCI Express, PCI, LPC and SMBus can be extended to support other peripherals for diverse industrial applications. CDG complements the COM.0 specification for COM Express modules without substantially affecting COM.0. Many of the COM Express vendors are redesigning their reference carrier boards to comply with CDG, which will greatly help interoperability. CDG can even improve the consistency of new module designs in the future.

Part of that consistency involves managing power. The industry-standard ACPI specification defines power-saving levels when the system is not operating, but implementation across COM Express modules has been inconsistent in the past. CDG addresses this point by defining the state of the many power rails that may be present in the system, including the standby nets that are powered when the main rails are at zero volts. In addition, suspend status signals and wake-up events are defined more thoroughly. CDG describes how to provide power to peripherals so that they continue to operate as desired during the suspect and soft off states. After all, these peripherals and part of the Southbridge must stay awake while the rest of the system is off. A system that won’t wake up again is not particularly useful.

A philosophical debate among COM suppliers is how to implement serial ports and other “legacy” peripherals within an architecture that is promoted heavily as “legacy-free.” CDG cautions carrier designers about the limited support for the

Low Pin Count (LPC) bus for such peripherals, and PICMG takes a neutral stance with regard to vendor offerings “under the table” as initialization of carrier LPC devices is heavily intertwined with the BIOS on each vendor’s product. Instead, CDG suggests the use of the driver-loading plug-and-play model of USB, PCI and PCI Express devices for serial ports and other legacy ports.

CDG contains all of the tricks of the trade that designers can deploy for a winning carrier board, including coupling capacitors, bypass capacitor types, bulk capacitance on power and standby rails, pull-up resistor values, series and parallel terminations, ferrite beads, reset circuits, and even more. Future challenges will include trying to layer USB 3.0, PCIe 2.0 and DisplayPort signals on top of the five existing pinout types.

SFF-SIG Steps up to the Plate

Next to bat, the Small Form Factor SIG wants to see the rugged markets served well with an all-in-one ground-up new COM architecture. Offering a fresh roster of new modular embedded computing specifications, SFF-SIG aims to tightly control COM implementations to reduce or eliminate the need for carrier design guides beyond the module vendors’ own reference schematics. Interoperability-by-

specification is a noble goal that time will have to test.

SFF-SIG’s new standard is called COMIT. The acronym stands for Computer On Module Interconnect Technology and is pronounced “com-it.” COMIT is a modular, high-speed connector system composed of the most common highspeed and legacy interfaces available from modern low-power chipsets (Figure 3). The purpose is to provide a compact, interoperable processor core connection architecture for future embedded systems designs. A legacy PATA/IDE interface connector is optional, and purposely left without other features so that it can “go away” by itself without compromising other features once SATA drives and SATA and/or SD SSDs fully replace their IDE counterparts in the embedded market over time.

COMIT addresses the emerging need for a COM standard that utilizes multisourced, state-of-the-art 10 GHz connector technology and focuses on new and future bus technology. Ensuring interoperability between COM modules is also an overriding concern. Longevity has long been the promise of COM products, and the ground-up new signaling optimized for ultra-low-power processors such as Intel’s Atom family and VIA’s Nano processors is an important future-proofing step April 2009

forward for COMIT. Power and signaling levels are two major areas of focus for interoperability.

To address power, ample power and ground pins are utilized for the supplies on COMIT. Thirty-seven grounds and 21 power pins are included for power, highspeed signal returns, impedance matching and control of EMI emissions and suscep-

tibility. The additional power and ground pins are an absolute necessity as interface speeds increase. Power control adheres to industry standard ACPI “ATX-style� signaling conventions. This eases module power control and ensures that all voltages necessary, except the standard 3.3V, 5V and 12V supplies, are generated on the processor module. This further mini-

mizes issues with power supply sizing and stability that occur when passing these processor-specific power rails across a connector. Suspend and battery voltages are also provided to the connector.

Another area that can cause crosscompatibility problems is the logic high level. A particular processor may specify that a signal is capable of only 2.5V, but an older carrier board may have this signal terminated or driven to 3.3V, causing reliability problems or failures. To mitigate these issues all control signaling across the 240-pin COMIT connector must be 3.3V tolerant. There is no wiggle room in signal definitions. Also, all input termination is included on the processor module, whether the feature is included or not. If a COMIT processor does not include a certain function, the module is required to include termination where necessary to ensure there are no floating inputs to the baseboard for all COMIT interfaces.

Tightly Controlled Sequencing

The COMIT Specification defines power sequencing requirements to ensure

module reliability and cross-compatibility. As shown in Figure 4, the real-time clock battery voltage must be up first, then +3.3VSB (standby) must come up or be already up, then the main 5-volt supply can come up, followed by the assertion of PWRGOOD (power good). Powering down proceeds in the reverse order. Compliance with this requirement prevents the lockups and erratic behavior of some COMs on the market today that are plugged into other vendors’ reference designs.

The SEARAY connector from Samtec provides high speed, high pin density and ruggedness. It is a 240-pin high-density (0.050” pitch) connector pair. Samtec and Molex are already cross-licensed to produce the SEARAY connector series, providing longevity for mil/aero, medical and industrial applications. The chosen connector system is capable of a differential signaling rate of 9 GHz bandwidth (at -3dB insertion loss) to support current and future high-speed signaling (Figure 5).

COMIT supports several common interfaces for low to moderate speed expansion requirements. Industry standard

serial interfaces include SMBus, I2C, SPI, Microwire and a UART. SMBus alert is included for power management alert functionality or general SMBus interrupt usage. Two chip selects are included for SPI/uWire, which can be expanded within the target device to any number needed.

SPI and SMBus are defined as 3.3V signaling. Five-volt tolerant devices may be used as long as they do not drive the SPI signals on the bus beyond the 3.3V nominal specification. The UART signals are defined as 3.3V only. Level translators must be on the baseboard where needed.

To handle cases where the particular COM doesn’t happen to support a feature defined at the interface, the COMIT Specification dictates that all features on the connector not used by the processor are terminated inactive where necessary on the processor module. This ensures that there are no floating inputs to the baseboard and no issues with unused features for the carrier designer to deal with. For the opposite scenario where a module’s feature is not terminated on the baseboard, the COMIT Specification dictates

that processor modules handle all input termination themselves. This ensures that there are no floating inputs to the processor module and no issues with unused features, which could lead to reliability and determinism problems.

While CDG and COMIT are thorough in providing COM designs for interchangeability, it is absolutely essential to use each module vendor’s documentation in order for carrier boards to be designed properly.

This includes analyzing multiple vendors’ products up front. It will take some time for the consistencies presented by CDG and COMIT to result in truly interchangeable COMs and carrier reference designs.

to support wake-up and other power-state transitions, which the ISA bus cannot support.

LPC requires a minimum of seven signals. LAD [3:0] comprise the four data lines, and the other three are control signals. LFRAME# indicates the start of a new cycle or termination of a broken cycle, LRESET# provides the same type of function as the PCI reset signal, and LCLK is a 33 MHz clock. Optionally there are sideband signals that convey power management and interrupts. For example, LDRQ# is defined to support DMA operation while SERIRQ allows peripherals to generate an interrupt if the host does not have ISA-based IRQ lines as interrupt inputs. Optional signals may or may not be on particular hosts or peripherals.

The latest generation of microprocessor chips from Intel (the Atom family) and from VIA (Nano) show continued retention of legacy software support and LPC bus for low-speed peripherals. Even though PCI Express and USB2.0 catch a lot of attention, LPC remains the unsung hero for boot ROM and legacy I/O devices.

For designers who need an LPC solution, off-the-shelf ICs exist in the market.

Adlink’s CoreModule 730 features Atom Z510/Z530 processors with SUMIT-AB expansion in the 90 x 96 mm ISM form factor.

Stackable Architectures

Although LPC was intended as an onboard inter-chip bus, new and recent embedded form factors bring LPC “offroad.” The form factors fall into the usual two classifications: Stackable and Computer-on-Module (COM).

In the stackable architecture, the Small Form Factor SIG (SFF-SIG, www. sff-sig.org) introduced a standardized way to bring LPC vertically off the host SBC to a mezzanine expansion I/O card. The interface, called SUMIT, includes a mix of high-speed and other low-speed buses and signals. The first SBC form factor available with SUMIT is called PicoITXe (Figure 1). The SUMIT-AB connector pair is located along the front edge.

Rather than creating a custom single board computer, an off-the-shelf PicoITXe SBC can be expanded with a PicoI/O card to add whatever I/O is needed by a particular application. This approach reduces time, resources and risk compared to full custom designs. Figure 2 shows a complete, off-the-shelf industrial I/O solution based upon tiny building blocks.

WinSystems chose the Lattice approach for their first Pico-I/O-compatible product. The PCO-UIO48-G is a 48-line, digital input/output module that will op-

erate from -40° to +85°C. The major feature of this card is its ability to monitor the first 24 lines for both rising and falling digital edge transitions, latch them, and then interrupt the host processor notifying that a change-of-input status has occurred.

This is an efficient way of signaling a Pico-ITXe single board computer (SBC) of real-time events without the burden of polling the digital I/O points.

WinSystems uses a Lattice FPGA device programmed to support the various input/output and interrupt configurations. It supports 48 digital I/O lines addressed through six contiguous registers. A 6-bit write mask register allows the user to disable writes on a byte basis to configure the group as a “read only” port. Each I/O line is individually programmable for input, output, or output with read back operation. The input lines are connected so that the current status

of its output port can be read from the corresponding input port (read back). If the port is used as input only, then the corresponding output port bit must be cleared. Each output channel is latched and has an open collector driver with a pull-up resistor. The I/O structure of the FPGA works with 3.3V but is +5V tolerant for maximum system flexibility.

Requiring all new I/O to be attached to either PCI Express or USB is unwise. It is like trying to get a simple drink of water from a firehose. LPC provides a proven, easy way to attach simple devices with reasonably deterministic real-time response, without requiring costly hardware and software overhead plus development time and money.

The very first SUMIT-based SBC on the market in the 90 x 96 mm ISM (Industry Standard Module) form factor is shown in Figure 3. ISM is the term for the pure board outline compatible with PC/104 enclosures, but without presupposing any buses like the PC/104 (ISA) bus. Adlink’s CoreModule 730 uses the Atom processor at 1.1 or 1.6 GHz for the lowest power implementation possible with all Intel ICs—only 5 watts. Best of all, this solution does not require a custom carrier board, and is more economical than pre-integrated two-board PC/104 solutions. For modest I/O requirements including basic control applications, this approach is tiny, rugged and easy to cool even in sealed enclosures.

Stackable I/O cards like Adlink’s MiniModule SIO plug into the SUMIT interface and connect the LPC bus to an SMSC legacy super I/O device on the I/O module. Stackable LPC bus is also available on larger size SBC form factors. To download the SUMIT specification, visit www.sff-sig.org.

PICMG’s COM.0 specification primarily uses LPC for port 80 debug support. Connecting the LPC bus to legacy super I/O’s might require the COM Express modules to have BIOS initialization support for the custom carrier board’s device a priori. That said, a number of the COM vendors offer carrier reference designs with an LPC header or with an onboard super I/O device that is initialized by the module’s BIOS. April 2009

INDUSTRY Insight

Reference design carriers often take the form of large ATX-style motherboards, since the size doesn’t really matter for a reference design. There are prototyping advantages to fitting into an ATX tower chassis. System OEMs wishing to add LPC devices to their carriers can follow the examples of the reference carrier boards.

Adlink’s Express-MV features Core2 Duo with the new GS45 chipset and LPC super I/O support for Winbond.

Figure 5

Ampro by Adlink COM 840 supports Core2 Duo two LPC devices: SMSC and Winbond.

“COMmon” Ground

Most COMs from major suppliers contain a BIOS that can initialize an LPC super I/O device. Typically the COM vendor must choose in advance what device to support. The Express-MV product shown in Figure 4 initializes the Winbond 83627 IC, so carriers designed for Express-MV that want to use legacy I/O need to select the Winbond device.

For SMSC or other super I/O device, a custom BIOS would be needed. Figure 5 shows an Extreme Rugged -40° to +85°C module that is a rare COM with a larger BIOS firmware in order to support two super I/O devices (SMSC, Winbond, or both) on the carrier board. The BIOS support gives more flexibility to carrier designers to choose between two of the most popular devices without needing a custom BIOS. Finally, Figure 6 shows an unusual carrier board reference design that is 5.75 x 8” (EBX size), much smaller than ATX size, and is much more than just a reference design. The COM-EBX baseboard contains a secondary LPC BIOS socket as an alternative to the module’s BIOS, as well as an SMSC super I/O device for legacy I/O support. COM-EBX is even deployable in volumes as a rare -40° to +85°C Extreme Rugged carrier for COM 840.

Whether a stackable, COM, or even custom SBC architecture is chosen, the LPC bus gives legacy additional longevity. Clearly, legacy I/O didn’t become obsolete when it disappeared from most new chipsets. LPC offers a simpler, softwaretransparent, less expensive and lower power way to attach legacy peripherals to embedded systems than using high-speed differential pair topologies like USB, Ethernet and PCI Express. Legacy I/O continues to live on in embedded systems.

Small Form Factor Developments

Small but Mighty: Small Form Factors Gaining Ground Embedded applications such as industrial automation and medical are seeing rise in small but powerful designs.

Christine Van De Graaf and David Pursley, Kontron

A

pplication-specific technology and expertise are critical to any embedded design. Advantages such as 45nm technology are pervasive and long-term, impacting embedded architectures across the board—whether designing for airline inflight entertainment, transportation or telecommunications. Better graphics, greater security features and much more result from greater performance per watt and less physical space required for the design. Understanding small form factor options and their accompanying performance benefits is one of the most valuable weapons in a designer’s arsenal, especially in tandem with indepth industry-specifics that make all the difference.

The days of setting standards single-handedly are over—and non-proprietary form factors are set to play a significant role in the development of these embedded computer systems for vertical applications that are characterized by long-term availability and robustness. Industry standard form factors and compliant products have become something that suppliers simply have to offer.

Significantly more decisive is service and support, from the choice of form factor to after-sales service and technical support, as well as the right solutions for customers’ applications, taking into consideration the particular industry and necessary certification. This is true for all markets. For example, the medical sector is calling for its own standards for medical equipment including traceability and certified manufacturers. Other sectors such as transportation, automation, energy and the military each have other, individual regulatory standards. Based on all these factors, the generic portfolio of embedded computer manufacturers is increasingly concentrating on these vertical markets and offering dedicated design and certification services.

Ultimately, being well-versed in existing, new and evolving small form factors—along with the performance benefits and limitations they each bring to the table—and tapping the deep expertise of a manufacturing partner relationship, are the ways

for designers to best understand the alternatives available to them in meeting the performance standards of any particular embedded application (Table 1).

A Growing List of Applications

For example, development of embedded technologies for industrial automation is being driven by several key trends. Probably most important is the impact of space and energy savings achieved through Intel Atom 45nm architectures, enabling a vast new generation of cost-effective, energy-saving, high-performance industrial control solutions. Smaller controllers and platforms are in turn accelerating the trend of industrial Ethernet for connecting smaller PLCs that traditionally used field bus protocols. Using Ethernet as a central communication system improves overall performance and interoperability by enabling devices from different manufacturers to communicate on the same network.

SYSTEM INTEGRATION

The industrial automation market is also shifting toward vendors that can provide not only boards, but also design, engineering and manufacturing services, as well as a partner network allowing for off-the-shelf and customized, all-in-one solutions. And finally, the introduction of safety-related systems in accordance with the IEC61508 norm—a required standard by the end of 2009—will have a heavy impact. OEMs will need to add safety products to their portfolio, and the market for safety PLCs will grow rapidly.

Medical design is following a very similar path, with the sector experiencing steady growth based significantly on the trend toward ultra-portable medical devices. These tiny devices are improving data collection, speeding up diagnostic capabilities and genuinely enhancing medical care. With new technologies such as 45nm and valueadded power management, applications that previously faced barriers due to size, performance issues or power consumption limitations can now be developed using a standard COM implementation—an excellent small form factor example of today’s performance and function.

PC/104—Sufficiently Simple

In embedded applications where very low cost, small footprint and moderate performance are among the main criteria, PC/104 and PC/104-compatible modules tend to be the norm. With little or no customization, these off-the-shelf solutions prove more than sufficient for a wide range of implementations. With a CPU board and optional peripheral boards stacked together, PC/104 negates the need for a motherboard, backplane or card cage. Fitted with stack-through connectors, these pin- and socket-bus connectors provide a reliable signal path even in harsh environments.

Bus specifications for PC/104 are identical to those of ISA with the exception that PC/104 reduces the drive requirement for most signals to 4 mA of sink current, reducing overall power requirements and allowing ASIC devices to directly drive most bus signals without the need for separate driver components.

PC/104’s stability as a form factor and wide availability from nearly 75 vendors, make it an attractive option where simplicity is key and optimum performance is not required.

3U CompactPCI—Rugged and Upgradeable

Legacy issues inherent to many embedded designs can be addressed with 3U implementations of the established CompactPCI architecture (Figure 1). New features meet more harsh computing environment requirements. Many designers turn to 3U CompactPCI, which has much higher bandwidth, Gigabit Ethernet capabilities and more powerful rear I/O over alternative form factors. Unlike PC/104 and MicroTCA, 3U CompactPCI has rear I/O, and can be air- or conduction-cooled. It’s also inherently stiffer than its own 6U counterpart, meaning it meets more rugged standards and is less vulnerable to shock and vibration.

3U CompactPCI is very widely supported and there is a broad range of rugged chassis available for this form factor. And, if an older embedded system is already using CompactPCI, upgrades to the latest processors make an ideal replacement rather than migrating to a new form factor. Compute-intensive applications such as industrial control or airline in-flight entertainment are using 3U CompactPCI very effectively to meet performance requirements in rugged or harsh environments.

These overlaid images provide a clear comparison of related COM Express solutions, which now include compact and ultra-small form factor COM Express-compatible modules such as the microETXexpress-SP and nanoETXexpress-SP.

Table 1

A comparison of several embedded form factors and their potential applications.

Computer-on-Modules – Functionality in a Host of Sizes

For more complex applications, embedded designers should consider computer-on-modules or COMs. COMs encapsulate an entire computer host-complex on a small form factor module which is then mounted onto carrier boards containing application-specific I/O and power circuitry. These off-the-shelf compact modules readily contain all generic PC functions, from graphics, Ethernet, sound, COM and USB ports, to other system buses. The custom designed carrier board complements the COM with additional functionality required for the specific application, for example, medical imaging or capturing patient data such as blood pressure or heart rate.

COMs have been standardized through the Embedded Technology eXtended (more commonly referred to as ETX) standard, enApril 2009

The small footprint of MicroTCA is seen here with Kontron’s OM6040 and the AM4100 Advanced Mezzanine (MicroTCA) Card.

abling full PC functionality, minimum engineering and adoption cost, reliable connectors, slim design, and straightforward upgradability and scalability. ETX modules are highly integrated and compact (95 mm x 114 mm, 12 mm thick) COMs. The standardized form factor and connector layout that carry a specific set of signals—found in all ETX modules—gives designers the ability to create a single-system baseboard that will accept current and future ETX modules. The ability to build a system on a single baseboard using the COM as one plugin component simplifies packaging, eliminating cabling, and significantly reducing system-level cost—key issues in embedded design.

ETX has further evolved, with improvements to scalability and performance. The newer ETX 3.0 specification offers the same benefits of the original ETX standard, but also adds in 2x Serial ATA with no change in ETX pins, making new modules 100 percent pin-to-pin compatible with previous versions to ensure long-term support. Evolution continues with COM Express and its specifications that satisfy the higher performance market segments of embedded computing and illustrate the trend toward size reduction and mobility (Figure 2).

COMs are ideal for designs needing a great deal of application-specific customization and can accommodate a two-board solution (module plus custom carrier board). Well-suited to a high run of product and the need for some scalability from generation to generation, COMs are perfect for devices or applications that not only require scalability from generation to generation, but also within a single generation. Customizations designed into COMs’ accompanying carrier board can last generations with various CPU cores, for example, swapping out one for the next.

MicroTCA – Powerful Communication

When communication and bandwidth requirements go beyond the limits of these established technologies, MicroTCA can ante up with very high communication bandwidth, high availability and overall increased computing power in a small form factor. At the larger end of the small form factor realm, MicroTCA can be ideal for highbandwidth data communications applications such as image processing. Designers who understand its benefits will have another powerful solution to tap for the right design and end-use application.

April 2009

Up to 12 compute blades on a single backplane—all of which could potentially use a multicore processor—are directly responsible for MicroTCA’s high bandwidth for both communications and computing (Figure 3). A 3U or 4U system, for example, could have as many as 24 cores designed into MicroTCA’s very small footprint. MicroTCA designs can tap as many as 21 high-speed serial connections on the backplane, resulting in bandwidth of 2.5 gigabits per second for each connection. Depending on how the system is implemented, a broad range of communications bandwidth capacities is possible, ranging from 40 Gbits/s to > 1 Tbit/s.

Advances in multicore processing platforms have proven to offer higher compute performance, reduced chip count and lower bill of materials costs with drastically reduced power consumption. As technology shrinks and more real-estate becomes available on the die, chipmakers will continue to push for greater performance, using a combination of improvements in circuitry and more advanced manufacturing technologies. Intel is looking to its next-generation 32nm multicore processors to outpace demands well into the future.

In addition to the multicore trend, the level of integration is another important factor affecting embedded computing technology. This currently has the largest impact on the smallest form factors. Now that integration into the chipsets has taken place, the chipsets are being integrated into System-on-Chips (SoCs) as wafers continue to undergo increased integration and are currently available in 45nm and shortly in 32nm. Manufacturers are now in a position to develop, for instance, credit-card-sized computer-on-modules (COMs) that contain the latest processors in an even more energy-saving design.

Some of today’s most challenging and broad ranging design requirements are found in embedded applications. New technologies can be difficult to adopt and develop quickly, and as a result embedded markets frequently demand reliance on existing or legacy technology for speed and execution of a given design. On the other hand, new applications can be so demanding and communication-centric, they require more performance than earlier architectures have been able to deliver within a small footprint.

Wherever the application demands fall in terms of performance, designers must also consider issues of size, cost, scalability and upgradeability, all critical to the overall performance of embedded applications and their imprint on the embedded landscape.

Today, “manufacturers as engineering resources” are even more integral to the design process. Understanding not only the technical requirements involved in design, but also trends, industry influences, customer requirements and regulatory demands as design elements, make the manufacturer-designer relationship critical to time-to-market and the overall success of the design.

Atom-Based COM Express Module Boosts Graphics Performance

Continuing its rollout of embedded computer modules based on the Intel Atom processor family, congatec has introduced the conga-BA945, a COM Express module with type 2 pinout that conforms to the specified COM Express basic size of 95x125 mm².

The Intel Atom processor N270 has a clock speed of 1.60 GHz, as well as 512 Kbyte cache and a 533 MHz front side bus speed. Despite the high processing power, the processor gets by with a maximum power dissipation of 2.5W. Thanks to the power management provided by the congatec embedded BIOS, the actual values reached during practical use remain well below this maximum level. The congatec conga-BA945 supports Intel Hyper Threading Technology, which means with the appropriate software it has the capability of running two operating systems in parallel and completely independent of one another.

In contrast to the recently announced conga-CA945, which is an even lower priced and more compact COM Express compatible module featuring an Intel Atom processor, the conga-BA945 makes use of the more powerful Intel 945GME chip set versus the Intel 945GSE used on the conga-CA945. The 945GME chip set facilitates the parallel use of two memory modules, which allows the memory to be expanded to a maximum of 4 Gbytes and makes dual channel memory access possible.

In terms of graphics performance alone, the performance increase thereby achieved is more than 50%. The Intel Graphics Media Accelerator 950 graphics controller integrated in the chip set can access up to 224 Mbytes of video memory with a 10.6 Gbyte/s bandwidth. Output for the two independent graphics channels can be via 2x24 bit LVDS, SDVO, TV-Out or analog VGA. The conga-BA945 uses the EPI graphics standard and the VESA DisplayID definition for automatic recognition and configuration of flat panel displays.

In order to allow rapid system expansion, five PCI Express lanes, a PCI Express graphics slot (PEG 1x16), eight USB 2.0 ports, two serial ATA ports and the signals for two ExpressCards are provided. The range of functions is rounded off by a fan controller, the LPC bus for slow extensions and an HDA interface that can provide powerful digital audio. The maximum power dissipation of the conga-BA945 during practical operation is considerably less than 10W and it is therefore ideally suited for all mobile and fanless applications with high demands on graphics performance.

The conga-BA945 is available now with evaluation unit pricing of $362 each. congatec, Cardiff-by-the-Sea, CA. (760) 635-2600. [www.congatec.us].

Atom-Based Qseven Module Mates with Carrier Card

A Qseven family of embedded system solutions is based on Intel’s Atom processor. The Qseven module was initiated by congatec AG and SECO, and enhanced by Portwell in response to market demand for an even smaller form factor to take advantage of the Intel Atom processor’s already compact design. At a mere 70 mm x 70 mm—30 percent smaller than COM Express—and with a power consumption under 12W (+5V input), the Qseven is an appropriate module form factor to implement the Intel Atom processor Z5xx series and Intel System Controller Hub (SCH) US15W in terms of space, power consumption and thermal and expansion interfaces.

American Portwell Technology’s new Qseven family is a solution to enhance applications in the medical device, industrial control, gaming machine, portable device and COTS military markets. The interconnection between the Qseven module board and the carrier board is the MXM (Mobile PCI Express Module) edge connector. Introduced by NVIDIA and leading notebook manufacturers, MXM provides faster time-to-market for the latest notebook graphics. Common signals between the two boards include PCI Express x1, LVDS, SATA, SDVO, HAD, Gigabit Ethernet, Low Pin Count bus, Secure Digital I/O, SMBus and I2C bus.

The Qseven module board is installed on top of the carrier board for improved mechanical stability. This means a small keep-out zone that leaves more space on the carrier board for additional devices. It also means that the carrier board itself can be smaller. Either way, it makes the Qseven an even more economical solution.

PCI Express Frame Grabber Utilizes Full Potential of Camera Link-Compatible Cameras

A powerful image processing solution for Camera Linkcompatible cameras comes in the form of a PCI Express frame grabber from American Eltec. The PC_EYE/CL supports base, medium and full configurations. The PCI Express interface with four lanes (x4) delivers data rates of up to 1 Gbyte/s for maximum speed cameras with full interfaces. The frame grabber delivers speeds of up to 680 Mbytes/s. The PC_EYE/CL frame grabber has inputs for digital video data compliant with Camera Link standard Version 1.2. Since each of the two onboard Mini-Delta-Ribbon 26-pin connectors supports four ports, a total of eight ports (A-H) can be used.

This makes it possible to either connect two independent Base cameras, using ports A-C each, or one Medium (A-F), or one Full (A-H) camera. Each 8-bit-wide Camera Link port uses a high-speed 7:1 multiplexing scheme with a serial transmission rate of 2.36 Gbits/s for optimal utilization of cable capacity.

This DMA controller consists of two independent controllers, capable of transferring two video data streams into two independent memory regions. Image data is transmitted by DMA directly into the main memory or into the graphics card. A DRAM-based FIFO consisting of 1 Gbyte DDR2 RAM is available for applications with higher bandwidth requirements. Consequently, loss of image data can now be eliminated even if the PCI Express Bus is unavailable for periods that exceed one second. The video data interface, FIFO control, DMA and PCI Express x4 are all implemented in a flexible and powerful Arria GX FPGA by Altera. Firmware updates are controlled via the software. The system also supports PoCL (Power over Camera Link). Trigger and optically insulated I/O signals are routed through a 26-pole internal flat cord plug connector, while a sub-volume of these signals is transferred by a 9-pole micro D plug.

DLL format drivers for Windows XP/Vista and Linux are at the userâ&#x20AC;&#x2122;s disposal as part of the Frame Grabber Basic Tools. They are available as 32- and 64-bit versions. A set-up program supports the test and the configuration of the board under Windows. A reduced version of the Frame Grabber Basic Tools portfolio is available for real-time operating systems such as VxWorks or OS-9000 upon request. In this case, the parameters are simply integrated into the configuration files. This solution does not include display routines. Pricing for the PC_EYE/CL frame grabber is $1,260 in single piece quantities.

CANopen Stack Supports SocketCAN Drivers for Linux

The popular CANopenRT protocol software from IXXAT now supports the most recent implementation of the SocketCAN drivers for Linux using the Sysfs virtual file system. SocketCAN is a set of open source drivers and a network stack that extends the Berkeley sockets API in Linux by introducing a new protocol family: PF_CAN. Main components of SocketCAN are the network device drivers for different CAN controllers and the implementation of the CAN protocol family.

The SocketCAN framework has become part of a vanilla kernel starting with 2.6.25.

IXXATâ&#x20AC;&#x2122;s CANopenRT software has supported multiple user application threads interacting with one CANopen core stack module since its initial release. The abstraction of the CAN controller as a Socket interface now offers the possibility to run other CAN-based protocols, such as SAE J1939, on the same CAN interface in parallel to CANopen also on Linux platforms, similar to the versatility that is already available on Microsoft Windows systems with CANopenRT for the IXXAT VCI V3 driver. CANopenRT has been tested with SocketCAN drivers for NXP SJA1000 and Freescale MSCAN for Linux distributions based on the kernel version 2.6.

Real-Time Messaging Middleware Meets Secure Linux

The Linux operating system has a firm foothold in the embedded arena. Software developers like the fact that they can start developing with Linux without the overhead of a commercial OS to consider. Real-Time Innovations (RTI) has announced that RTI Data Distribution Service, its real-time messaging middleware, has been integrated with Security-Enhanced Linux (SELinux).

This combination provides real-time and high-performance distributed applications with the ability to securely distribute data by combining RTI’s high-performance network communications with the extremely flexible Mandatory Access Control (MAC) facilities of SELinux.

RTI Data Distribution Service allows distributed applications to securely exchange messages and data by authenticating peers and encrypting information that is sent over the network. The MAC capabilities of SELinux add several additional levels of protection against misconfiguration, software errors and application vulnerabilities: System-wide security policies control which applications are allowed to communicate with each other. Even applications with the appropriate credentials and keys can communicate only if explicitly provisioned to do so. Files containing keys, configuration information and logs are protected from unauthorized access. RTI Data Distribution Service and a reference SELinux security policy are available today from RTI.

VPX Load Board Helps Verify Power Spec Conformance

A new 3U VPX load board helps confirm that a chassis meets the VITA 46/48 power specifications for VPX and aids in locating hot spots within the enclosure. The load board from Elma Electronic functions to test a system’s cooling capabilities by first applying the load to the power supply for verification and creating the necessary heat to confirm chassis cooling. By locating hot spots in the chassis, a system designer can verify where to optimally redirect the airflow to prevent overheating. The 3U VPX load card features a microcontroller-based stepped load control to 100W maximum. The rotary switch selects the voltage setting, while pushing the ON switch will cycle between different power levels shown on the LED display. The set load power levels are saved in EEPROM. Other features include a power reset button (to minimum level) and a SYSRESET signal on the two test point outputs. Go-No-Go indicators are present for 3.3V, 5V, 12V, +12V_Aux, -12V_Aux and 3.3V_ Aux. There is also an IEEE injector/ejector handle to provide a secure and convenient latching mechanism. Bustronic is also planning a 6U VPX Load board as well as a conduction-cooled version in the coming months. Pricing is under $1,000 depending on volume and type.

Ruggedized Conduction-Cooled CompactPCI SBC with Dual PMC/XMC Sites

For harsh operating environments, a new single-slot CompactPCI dualcore processor, dual PMC/ XMC, single board computer uses the 1.5 GHz Core 2 Duo mobile dual core processor from the Intel embedded roadmap. The ruggedized PP 452/031-RC from Concurrent Technologies is suitable for low power intensive processing applications where the dual processor cores can access 4 Gbytes of soldered DDR2-400 ECC SDRAM at up to 6.4 Gbyte/s.

For I/O flexibility there are 2 PMC/XMC sites supporting rear I/O, plus dual SATA150, dual Gigabit Ethernet, USB and RS-232 interfaces as well as onboard or removable flash disk storage including CompactFlash. The board also supports PICMG 2.16 (Ethernet fabric), PICMG 2.9 (IPMI) and PICMG 2.1 (hot swap). All boards can operate as a system controller board, a peripheral board or as a satellite board. A range of commercial extended temperature versions is available. Applications for this conduction-cooled board are expected within the defense, industrial control and transportation markets.

The PP 452/031-RC conduction-cooled board, including conformal coating, operates at altitudes of -1000 to +50,000 feet (-305 to + 15,240 meters) over -40° to +85°C (no airflow) and ruggedized (VITA 47) to operate at a shock of 40g (11ms, half-sine), sine vibration 5g (5 Hz-2 KHz) and random vibration, 0.1g2/Hz (10Hz-1KHz) with 6dB/octave from 1 KHz to 2 KHz. The board supports the 1.5 GHz Intel Core 2 Duo L7400 processor (soldered) with 4 Mbytes L2 cache shared between the cores, a 667 MHz front side bus and supports 64-bit operating systems. The Intel E7520 server class chipset and 6300ESB ICH are used to complement the processor to achieve a high-performance, yet low-power, core architecture.

Each PMC site supports up to 66 MHz PCI-X operation as well as either x4 or x8 PCI Express XMC interfaces. This high-functionality board offers an array of functionsâ&#x20AC;&#x201D;plus rear I/O consisting of 2 SATA150, 1 RS232, 3 USB 2.0 and dual Gigabit Ethernet interfaces.

NEWS, VIEWS &

Comment april 2009

Warren Andrews Associate Publisher

A View from the Height

T

hroughout the pages of this magazine our editors bring you the latest technology and products to help make your embedded computer decisions easier and more effective. We provide the technological details, product features and benefits and applicability to specialized requirements to help you evaluate where you’re going. And, over the past year or so, we’ve seen dramatic changes driven by fundamental developments in the technology, shifts in the requirements of the marketplace and new and exciting trade-offs in power, size and performance.

In this small corner of the book, I try and provide some of the backdrop and rationale of what makes the rest of the business work. For one view we look from the 10,000-foot level and examine the changes in the application areas. Certainly the economy, political environment and sociological events bring new dimensions to our industry. We try and identify burgeoning opportunities in everything from food safety and health care to advanced productivity tools in industrial control and automation.

For example, last issue we discussed some technology ramifications of the Stimulus Bill recently passed by Congress. In health care, funds (more than $19 billion) for health-information technology, essentially E-records, are likely to be a boon to a variety of embedded computer makers.

Following that rabbit down the hole a bit, it seems that at least some of that largesse will find its way into the hands of big companies such as General Electric, IBM and even Intel. However, several smaller players are now gearing up as they see multiple opportunities for data acquisition, management, portable/mobile devices and bedside/office monitoring and storage equipment.

And, we can expect much of this equipment to carry relatively high ASPs as it will likely have to have the blessing of the FDA. There’s a lot to be done. According to a survey by the recently named Coordinator for Health Information Technology— a new position from the Obama administration—only 1.5% of hospitals have adopted what the survey defines as a comprehensive hospital-wide system. But even more significantly, only 9% of U.S. hospitals have electronic health records at all. Cost was

52

April 2009

the most commonly mentioned barrier to the adoption of such systems, opening the door for the economic stimulus package money.

Basic Technology Developments

Still at the 10,000-foot level, we look at basic technology developments such as semiconductor process developments, advances in packaging, and materials that impact new products at the most fundamental levels. While we don’t tunnel down into the basic physics of these advances, we look at how some sea changes will affect applications areas. For example, Intel’s latest 32nm process (which the company is currently holding tightly under wraps), will undoubtedly bring a new generation of lowpower, compact embedded computers to the scene.

While much of the current development is under strict nondisclosure by Intel, indications are that new lower-power versions of its recently released Atom will reduce power and heat generation by at least another order of magnitude. The result will unleash 32-bit processing power to the embedded community at new levels of price, performance and power efficiency.

And finally, we try to bring relevance to the market by looking at indicators that may impact the business in general. We look at supply lines and business health of materials and components— from semiconductors and connectors to PCB deliveries—critical to fabrication of many systems. These provide a snapshot of where the industry has been and in some cases, where it’s going.

In that regard, we looked at a study from Longbow Research that examined the EMS market in North America and Europe and saw that both January and February posted declines in the low to mid single digits in contrast to the historical data from the past three years that posted sequential increases of a similar or greater magnitude.

Not surprisingly the study looked at sales by end market where defense and medical (excluding large devices) remained stable while other segments of the market were flat to soft. It reports the telecom market weakened somewhat while industrial and automotive markets were very soft. An interesting statistic is that the consolidated

(rigid and flexible PCBs) three month average book-to-bill fell to 0.89 in January—with shipments off 17% year over year.

Stimulus Dollars for Broadband Development

Stimulus money is still some distance from reaching firms providing broadband service, but already companies are facing off on how the services should be expanded. While it seems that there is agreement that stimulus money should be used for extending broadband to “unserved areas,” there is disagreement with the definition of unserved and how it differs from underserved. That difference could be critical in deciding who gets stimulus money and who doesn’t.

Midsize phone companies and others argue that some stimulus money should be spent on new Internet lines in areas that already have service. On the other hand, established broadband providers are worried that the government will give money to smaller competitors looking to build new and potentially faster service in markets that already have some broadband—thereby giving them a leg up on those traditional suppliers. Decisions on rules for granting the money are to be made soon and these decisions could impact technologies such as the emerging Wi-Fi. Exactly how the money is allocated will also likely affect a variety of embedded computer suppliers that sell into different broadband markets.

Headlines Impacting the Industry

Cisco Targets Data Centers: Cisco plans to begin making computers aimed at data centers looking for a turf war with rivals IBM and HP—and possibly Dell. It is reported that businesses will spend about $100 billion on data centers in 2009 according to analysts firm IDC. Cisco hopes to aim at some 25% of that with its Intel-processor-based blade servers. More as it’s available.

Sun Microsystems’ Final Chapter? According to sources, Sun has been shopping itself over the past several months and may have found a suitor in IBM. Intel President, Paul Otellini, in a talk to employees recently indicated that Sun “was shopped around the Valley and around the world in the last few months.”

Was there an implication there that Intel might have been considered a possible suitor?

IBM Cuts U.S. Jobs, Expands in India: If you’ve been watching the news, you’ve probably seen that Big Blue’s latest employment initiative flies in the face of the new administration’s goal of keeping jobs in the U.S. The company is dropping almost 5,000 jobs in the U.S.—transferring many of those jobs to India. IBM has continued its current trend increasing the number of employees working abroad from 65% in 2006 to 71% now. IBM employs some 400,000 workers. Many of the jobs lost will be from the global business services unit. And while that doesn’t immediately affect the embedded computer industry, it sure indicates that nothing is sacred. Add to that the administration’s recent move to restrict employment of foreign professionals in the U.S., and it leaves the message that outsourcing may be the most practical solution.

Chip Makers in the News: Intel continues to reap its share of

headlines this month as the latest version of the company’s Xeon family of server chips, code named Nehalem, will be brought out just before this goes to press. This entry is expected to be at the heart of the new breed of Cisco servers entering the market. But most of the other big server makers are also expected to make announcements when the chip is formally introduced.

In other Intel news, the company will be entering into a “strategic” collaboration with, of all companies, TSMC—a System-on-Chip maker and a very different kind of semi company from Intel. The collaboration allows TSMC to make chips that combine the circuitry of the Atom processor with other circuits.

Intel hopes to get a leg up in the cell phone market and other embedded computer applications this way in order for it to diversify from the computer industry.

This may also be Intel’s foray into a wide range of products Intel calls MIDs (Mobile Internet Devices). Back several months ago, and again at an investor meeting late last month, Intel CEO Otellini said the company plans to more aggressively pursue a lot of SoC business. TSMC makes a variety of highly integrated chips for such companies as TI, Qualcomm and Broadcom.

And Intel’s largest adversary, AMD, has formally named the spinoff of its manufacturing capability calling itself Globalfoundries. The new company, backed by investors from Abu Dhabi, is based in Silicon Valley and continues to manufacture at other facilities here and abroad. AMD has retained about 34% of the new company, which is starting off with 3,000 former AMD employees. Reduced demand from a glut of manufacturing capacity due to the worldwide recession may have it off to a rocky start. In other AMD news, former 3Com Chief Executive Bruce Claflin has been named AMD chairman.

IGP Market to Disappear by 2012: JPR (Jon Peddie Research), a consulting firm for graphics and multimedia, completed a study that indicates the end of the market for the popular integrated graphics processor chipset, IGP. The study says that in 2008, 67% of graphics chips shipped were IGPs. In 2011, the company says it will drop to 20% and by 2013 down to less than one percent.

The study goes on to say that market shares will shift as suppliers of IGPs such as AMD, Intel, Nvidia, SiS and VIA find the opportunities for chipsets diminishing and will seek to develop new products that take advantage of their specific strengths. Evidence of that already is appearing as Nvidia strengthens its highend offerings with development tools, and on the mobile side has introduced the Tegra platform, which relies on an ARM processor and Nvidia graphics. Also, AMD is going head-to-head with Intel with its Fusion and embedded graphics CPU—yet still not giving up its plans for strategic markets such as netbooks.

All in all, it’s been a busy month. And I’d be remiss not to pass on—if you somehow missed it—that Bill Gates has regained his crown as the richest man in the world.
