Life in the Cloud (sans Harp and Halo)
S
ometimes a minor observation can lead you to realize that the world around you is fundamentally changing. Last week I went in for my yearly physical, which of course always involves an EKG. Usually, the nurse wheels in a cart with a cool-looking EKG machine and I obviously wonder whose boards and modules I might find if I opened it up. This time was different. The nurse wheeled in the cart but there was no EKG machine. Instead there was a normal, everyday laptop PC and a cluster of probes. The probe wires went into a small hub that connected to the laptop’s USB port. The entire functionality of the EKG machine was now in software on the PC. Now, this is not in itself a major development; it’s actually fairly predictable. But it showcases two major things that involve the use and nature of embedded systems. First, the processor side of most designs is becoming commoditized and driven by the semiconductor manufacturers. Whether the processor is a laptop PC or an Atom or VIA-based COM module, OEMs mostly do not design the CPU side, they select it from what is available on the market. The corollary, then, is that the major design challenge is on the I/O side. You still can’t buy a set of EKG probes at Fry’s Electronics. The same goes for the I/O subsystems of a vast number of embedded controllers, instruments, data acquisition systems and more. Many, many of these require detailed engineering to enable them for their specific applications. The second, equally obvious realization is that the other big design challenge is in the software. Older EKG machines would spit out a strip of paper with the waveforms on it, which the doctor would examine, perhaps discuss with the patient, make a few notes on and then fold up and stick into a folder. Now that same EKG data is in memory and disk, and although it is presented in the visual form familiar to the doctor, the data is also available for analysis such as flagging an alert or giving quantitative values for diagnosis. But the biggest thing is that the data is available online—to quickly send to a specialist for consultation—or for whatever purposes may lie beyond such as statistical analysis with the results of thousands of other patients, for correlation with other medical data like diet, medications. The possibilities are endless and that’s the point.
Now extrapolate to other small medical devices like O2 meters, blood analyzers and more. MRI machines are not based on PCs, but their basic data is digital. But now let’s multiply this by everything, by all the embedded controllers and instruments out there that have their I/O tendrils into the real world. They are not just pasting labels on bottles, running milling machines, industrial processes, transportation systems and climate controls. They are also collecting data. At first the data was intended for use by their own internal software, but thanks to today’s increasingly universal connectivity, that data is potentially available for use by applications both immediate and yet unheard-of. Today, embedded systems represent not only devices for control and automation; they are also the means for connecting the real world to “the cloud.” For example, an organization wishing to monitor and analyze data as diverse as machine power usage, lighting, plant environmental conditions and more will not have to install separate data collection devices. Mostly the data will be available as a byproduct of the already installed control and automation systems and can be used and correlated across different domains at the IT level to implement all manner of management functions. Already transportation and fleet management systems are pulling together data from GPS, passenger counters, fuel consumption monitors, sensors in bearings, RFD monitoring of freight and traffic conditions for efficient routing, maintenance scheduling and payload tracking by pulling different aspects of this data together in different applications. The convergence of the small embedded device with “the cloud” will open up huge new areas of innovation at the macro level as more and more devices are connected at the micro level. Software at the middle level—running on all those powerful processors we sometimes think have nothing to do—will have the ability to prepare data in preprocessed values and formats to make it instantly usable at the IT level. And have no doubt that clever minds at the IT level will be thinking of ever more creative and useful ways they can use that data to make their own overall operations more efficient and cost-effective. Break out the harps and halos. RTC MAGAZINE DECEMBER 2009

INDUSTRY
INSIDER DECEMBER 2009 NASA’s Human-Robotic Systems Communicate Using PublishSubscribe Middleware NASA is using middleware from Real-Time Innovations (RTI) to control a fleet of experimental robots. The NASA Human-Robotic Systems Project is developing four prototype robots at four major research centers. The robots share a network data architecture that uses RTI middleware. The Human-Robotic Systems Project includes four robots with four very different missions. NASA’s Ames Research Center in California is building a robot called K10. Because it carries an array of cameras and laser scanners, this robot can operate in an unstructured environment by itself or with human oversight. ATHLETE, a large, six-limbed robot built at the Jet Propulsion Lab, is designed to transport large payloads across a wide range of terrain, including steep slopes and rocks. Johnson Space Center has built a Lunar Electric Rover—or LER—that could transport astronauts across long distances on the moon or Mars someday. Finally, Langley Research Center is building a crane-like robot called the Lunar Surface Manipulator System (LSMS) to help with assembly and loading missions on planetary surfaces. These systems are prototypes for vehicles that will someday operate on extraterrestrial surfaces. Today, the prototypes are being tested in harsh analog environments. For instance, during the summer, K10, ATHLETE and the LER spent weeks at Black Point Lava Flow in Northern Arizona. All of these robots will sometimes be “teleoperated” with direct joystick control. This requires high-speed communications with the operator. At other times, these robots will be operated with long transmission delays over low-bandwidth communication links. In addition, each system must integrate many other applications, including sensors, graphical interfaces and navigation. The robots also run a variety of operating systems, including Linux, Mac OS, VxWorks and Windows. All the NASA robots are designed to share a common data communications interface. This saves significant deployment costs, reduces training requirements and leverages code and experience between the centers. Someday, when NASA launches the systems, having only one communications architecture will eliminate the need for duplicate testing, simplify operator equipment and reduce ground staffing. The Data Distribution Service (DDS) for Real-Time Systems standard supports very flexible service parameters. NASA has found that they could adapt the middleware to the unique needs of each robotic system. RTI Data Distribution Service provides a messaging and integration infrastructure for demanding, missioncritical distributed applications. It combines deterministic performance, low latency, high throughput and fault tolerance into a fast, scalable architecture for real-time systems. By enabling loosely coupled integration, the solution significantly reduces long-term software maintenance costs. Individual subsystems may be modified, added or upgraded without impacting existing software.
Cavium Networks to Acquire MontaVista Software
Cavium Networks has announced that it has signed a definitive agreement to acquire MontaVista Software for $50 million, comprised of approximately $16 million in cash and approximately $34 million in Cavium Networks common stock. The deal is expected to close in December 2009. This acquisition is intended to increase Cavium’s software and services revenue, and is ex-

pected to be gross margin and non-GAAP earnings accretive in 2010 and beyond. After the acquisition, MontaVista Software will run as a separate operating unit and will retain the MontaVista brand name. In addition, Cavium Networks says it will continue the MontaVista business model and support embedded Linux on multiple architectures from multiple processor vendors. MontaVista will maintain its own dedicated and focused engineering, sales
and product management staff. According to Cavium, MontaVista’s customers and partners will see no change in customer facing field operations, and the Webbased support and product download sites will be maintained.
PICMG Adds RapidIO for AMC Modules
PICMG has announced the adoption of the AMC.4 specification, which adds RapidIO inter-
connects to PICMG’s Advanced Mezzanine Card (AdvancedMC) family. RapidIO addresses the high-performance embedded industry’s need for reliability, increased bandwidth and faster bus speeds in an intra-system interconnect. The architecture is a high-performance, packetswitched, serial technology that is widely used in the signal processing, networking and communications markets. The AMC.4 specification is a subsidiary to PICMG’s AMC.0 specification that defines the mechanical, interconnect, management, power and thermal requirements for the industry standard mezzanine. The AMC.4 specification defines RapidIO implementations on AdvancedMC and helps support PICMG 3.5, which defines RapidIO on AdvancedTCA modes. The new specification includes standard implementation guidance for specific configurations like 1x and 4x RapidIO.
Wind River and Kontron Sign Distribution Agreement for VxWorks and Linux
Wind River and Kontron have announced a global, multi-year agreement under which Kontron will distribute Wind River’s VxWorks and Wind River Linux operating systems. This agreement extends a decade-long collaboration, and is expected to extend the software and service offerings of Wind River and Kontron. The two companies will initially target the industrial, medical, military and aerospace, transportation, and networking market segments. Kontron also joins the Wind River Partner Validation Program, initially with its Kontron nanoETXexpress-SP module validated for use with VxWorks 6.7.
By working together to validate Wind River’s embedded operating systems with leading partner software and hardware, Wind River and its partners are together providing a pre-validated solution stack to directly address integration costs, time-to-market and long-term support. Under terms of the distribution agreement, Kontron will be able to resell VxWorks production licenses, and also agrees to work with Wind River to proliferate Wind River Linux for use by joint customers. Wind River will continue to provide hardware and software tools, development environments, source code and support contracts for joint customers.
ZigBee Alliance and the American Telemedicine Association to Collaborate
The ZigBee Alliance and the American Telemedicine Association (ATA) will educate both health care professionals and consumers on benefits of telecommunications technologies as part of a new liaison agreement. The groups will focus on the many capabilities of ZigBee Health Care, an open standard for secure monitoring and management of noncritical, low-acuity health care and wellness services. ZigBee Health Care is designed to reduce patient care costs while improving care and quality of life for patients and consumers. ZigBee Health Care offers the ATA, a readyto-implement telehealth solution featuring interference-free and secure wireless connectivity, capable of supporting many common non-critical medical devices. It also provides a robust network suitable for secure, remote patient monitoring and
one that helps aging and physically challenged people remain independent. The ZigBee Alliance and the ATA will work together to advocate telecommunication solutions to diverse groups ranging from traditional medicine, academic medical centers, technology and telecommunications companies, e-health, medical societies and government, emphasizing the benefits telecommunication technology provides in improving the quality and efficiency of medical care to patients. ZigBee Health Care provides a global, open standard for interoperable wireless devices enabling secure monitoring and management of non-critical, low-acuity healthcare services targeted at chronic disease management, obesity and ageing. It provides full support for IEEE 11073 devices. The standard is designed for use in homes, fitness centers, retirement communities, nursing homes and a variety of medical care facilities.
NVIDIA and Partners Form Computing Development Ecosystem
Nvidia and its ecosystem partners will deliver, over the next few months, a broad set of software releases to developers using GPU Computing in their work. These updates feature major releases across a broad spectrum of GPU Computing development languages, tools and libraries. Included are updates from Nvidia for its CUDA C compiler, with additional support for C++ and its upcoming GPU codenamed “Fermi.” Nvidia is also releasing its R195 driver that includes new extensions to its OpenCL 1.0 conformant driver and toolkit, and a beta release of the Nvidia
codenamed Nexus, the industry’s first development environment for massively parallel computing, which is integrated into Microsoft Visual Studio. Alongside Nvidia’s own updates, several partner releases from industry leaders in software tools are available now, including The Portland Group’s CUDA Fortran solution, Allinea’s Distributed Debugging Tool (DDT) and the TotalView debugger. Among the updates to Nvidia and its partners’ parallel computing development tools are the following: CUDA Toolkit 3.0 Beta: With the CUDA Toolkit 3.0 Beta, developers can start developing applications today for the Nvidia Fermi architecture. This beta release includes features such as ECC reporting, Dual DMA Engine, Concurrent Kernel Execution and Nvidia Fermi HW debugging support in cuda-gdb. Performance profiling is included for both CUDA Visual Profiler and the OpenCL Visual Profiler. Also included is support for a new unified interoperability API for Direct3D and OpenGL including Direct3D 11. OpenCL 1.0 Extensions: New extensions include support for double precision, OpenGL interoperability and the new OpenCL Installable Client Device (ICD). These new features supplement existing Nvidia-only support for 2D image, 32-bit atomics and byte addressable stores. Nvidia ‘Nexus’, the codename for the development environment for massively parallel GPU applications, integrated into Microsoft Visual Studio IDE: Comprised of a Debugger, Performance Analyzer and Graphics Inspector, this beta release gives GPU Computing developers an immediate boost in productivity through common and easy to use tools.
Report Says Graphics Add-in Board Market Rebounds in Q3’09
While a market rebound for graphics add-in boards (AIBs) didn’t occur in sync with the broader graphics hardware markets, it did eventually materialize in the third quarter, according to a report from Jon Peddie Research. The market (along with most others) had suffered a major drop in Q4’08. Volume flattened in the first quarter as draineddown inventories regained some lost weight, and Q2’09 mercifully showed demand stabilizing and more evidence the market had bottomed. Looking toward the third quarter, Jon Peddie Research had been expecting a bounce in the second half, with the first signs to be manifested in Q3’09. And to the relief of many, that’s how the story unfolded. The quarter saw 20.3 million graphics cards shipped, up 21.0% sequentially, a particularly robust number considering the two major vendors were on the tail end of product cycles. Even in the context of a year-over-year measure, the quarter’s 7.2% decline was significantly more moderate than had been seen in the previous quarters.

SMALL FORM FACTOR
FORUM
Colin McCracken & Paul Rosenfeld
Embedded Chicken
W
e wouldn’t want to be an SBC vendor in today’s small form factor market. As always, the new processor/ chipset treadmill from Intel and VIA continues to churn at a pace to make the average board vendor collapse with exhaustion. You finish releasing Atom or Nano boards in umpteen different form factors and bus interfaces just when new processors and chipsets hit the streets. And you do it all again. And again. And that’s not even the worst part. All your competitors are doing the same thing, with the same chips, in the same cookie cutter form factors. It’s the worst kind of commodity market— high investment with low product differentiation. No wonder North American and European board vendors fear the low production costs achieved in the Far East. For I/O vendors, it’s another story entirely. Digital and analog I/O is pretty much the same today as it was in the 1890s— oops, we mean 1980s. Sure, incremental improvements in feature sets or increased functional density occur every once in a while. But RS-232 is RS-232. Here, the wide variations in performance and feature set enable a supplier to stake out unique territory and to dominate that territory for years. Once designed into an embedded application, the I/O that drives that application is usually locked for life. CPUs may come and go, but the I/O portion of the application is unassailable. Changing the I/O would affect the application software, validation, FDA approval, etc.—completely out of the question. So what’s a self-respecting I/O vendor to do with his/her R&D dollars? Nibble away at other turf knowing that qualification of a new I/O board in an existing application has little chance of happening? We believe the I/O vendor community can take a leadership role as embedded technology moves grudgingly from older parallel bus technologies (ISA and PCI) to new high-speed serial bus technologies (PCI Express, USB). For years we’ve heard the same argument—“we don’t need the speed.” But it’s no longer a sufficient excuse to keep one’s head in the sand. Like it or not, the processor and chipset suppliers who drive the entire
10

embedded application spectrum are going to make life hell for designers until the I/O community ponies up to the new bus architectures. So now we move to argument number two. “I don’t want to do any I/O cards with new bus architectures or form factors until there are SBCs on the market to plug into.” Ever think that the SBC vendors feel the same way? “We don’t want to support a new expansion bus until there are I/O cards that plug into it.” What is this, a giant game of embedded chicken? The best path, as usual, is somewhere in the middle. The SBC vendors have little choice but to follow the processor/chipset path or fall off the treadmill and die. What they do, however, is stand on their heads to provide compatibility with legacy I/O, adding cost and complexity for everyone. It’s time for the I/O community to take its collective head out of the sand and realize that it is the I/O vendors, not the SBC vendors, who control how and when the new bus and form factor technologies will achieve critical mass. It’s the ecosystem, stupid! I/O vendors are going to have to take a little risk—and start converting their product catalog to new serial bus and form factor technologies before a broad set of SBCs hits the streets. Only if the I/O vendors take the lead on bringing these new bus and form factor technologies to market will the small form factor community stop appearing as if they are running downhill backwards. The risk is small. The processor and chipset suppliers will see to that. The SBC vendors have no choice. Return on investment may take longer than many would like. Such is the cost of progress. And to be blunt, we’re not advocating a toe-in-the-water approach here either. It’s jump in the pool time. You can hold your nose, but you need to be wet all over. So, Mr. and Ms. I/O Vendor, you need to convert your product catalog to PCI Express or USB or SPI or all three. Now. Every month you wait is another month the entire small form factor community continues to grasp at obsolete straws that Intel abandoned generations ago. And you know who’s going to win. Again!

tions infrastructure, we are looking at extremely rapid growth in global IP traffic, and this will be made even more extreme by the demand for high-performance connectivity to service the growing traffic in high-definition video (Figure 1). In addition, with a large portion of industrial Ethernet and long-haul networks moving to 10 Gbit/s, there will be increased demand for power-efficient transports such as OTN to handle legacy technologies such as SONET until the world transitions into an all-IP infrastructure. All this translates into increased electricity use and the opportunity to serve these markets, which is what AppliedMicro has decided to focus on. A snapshot of the company’s view of power consumption paths is shown in Figure 2. Interestingly, they have decided on a fabless business model, which puts them in partnership and cooperative relationships with both customers and fab companies. Currently, AppliedMicro is working closely with Taiwan Semiconductor Manufacturing (TSMC) and has gone to a bulk CMOS process at 40nm. The company has also announced that it is targeting a 28nm process for many of its system-on-chip products, which are primarily based on the Power architecture. Such a strategy involves huge commitments on the part of fab partners, who must be deeply involved with the AppliedMicro’s process engineers. It also requires building the fab partner’s confidence to invest in the advanced equipment needed to support these smaller geometries and processes. Of course, simply shrinking the geometry is not the whole solution of power reduction. It can even produce complications due to the fact that even reduced power consumption has less thermal mass to dissipate the heat that it does produce. According to Ravuri, “You can’t just marginally reduce the geometry and expect a huge power reduction. There are several other things you have to do.”

Among these “other things” are innovative circuit design and intelligent power management within the SoC. And here, of course, is where the details become a bit sketchy, because optimizing these technologies is what lies at the heart of AppliedMicro’s efforts. Despite all the publicity we’ve heard about intelligent power management for things like battery conservation, Ravuri doesn’t seem too impressed. “Typical processors in the past really didn’t pay much attention to power management,” he says. On the other hand, he notes, “You can build efficient processors and dissipate as much heat as possible but that doesn’t mean your processor is not being used. If it’s still running, it’s still consuming energy.” Processors with different levels of sleep mode are, of course, fairly familiar, but Ravuri says there is no real standard way of using sleep modes. That would seem to imply that the developer is left on his or her own to figure out the optimal way of utilizing available sleep modes for any given application. Putting the CPU into too deep a mode may affect critical performance, while not putting it to sleep in certain situations might adversely affect power consumption. These design challenges are certainly not going to go away, but Ravuri is announcing that AppliedMicro is taking a somewhat more hardwarecentric approach to power management. This may be aided by the fact that the devices are SoC, which include the Power processor architecture plus other elements and peripheral circuits that would not be on-chip in the case of a general microprocessor. “We have these elements inside the device that software can control, but some of the intelligence is actually embedded within the hardware itself, which makes it easier,” he says. Here again, the deep details are part of AppliedMicro’s “secret sauce,”

but Ravuri did mention the example of energy-efficient Ethernet, which is a proposed IEEE standard 802.3az, so we may speculate that this example is the inspiration for other proprietary techniques being developed in-house by AppliedMicro. Energy-efficient Ethernet involves intelligent MAC hardware that can detect the load and automatically negotiate the link downward in cooperation with the peer.

Of course, how low to negotiate and under which circumstances is still a design decision, as is how absolutely low you can go and not risk unacceptable packet loss when an application or the operating system decides to override the power saving mode.

actly what choices and techniques will be offered to system developers and the nature of the decisions they will then need to make to optimize power use and performance. The strategy then is the combination of advances in process technology and basic circuit design plus innovative hardware design for control modes to manage power as well as to reduce it. And then there is the matter of performance—do we compromise things like clock speed to achieve power reduction? Ravuri’s short answer: “What would be the point of that?” Of course, that’s easier said than done. So far, the only publically announced numbers for power/performance enhancements involve a single device, but are nonetheless significant. The 405EXr is a Power Architecturebased SoC device used in wireless LAN points and NAS storage systems. AppliedMicro has announced a reduction in worst-case power consumption from 3.5 watts to 2 watts—a drop of almost 40 percent. At the same time, the peak clock speed remains 533 MHz. Currently the company is migrating all customers for this product to the low-power version, and all new customers will receive that version as well. We appear to be on the threshold of a general move to radically reduce the power consumption of silicon. The advent of the Intel Atom a few years ago based on that company’s 45nm geometry (soon to move to 32nm) has spread to other Intel product lines such as their multicore products. Another x86 player, VIA, is staking its turf in the low-power arena as well. As the learning curve advances, others are sure to follow because the system advantages can be tremendous.

In-House vs. COTS Systems
This pressure for COTS systems in the HA space is driven first and foremost by straightforward economics. The expense and investment for High-Availability systems has traditionally required a large in-house investment by systems vendors. While these traditional in-house systems were of solid value and solved real problems, the investment demands on these systems have outpaced even the most responsive and innovative vendors. Solving this challenge demands a level of cooperation among industry players. Key standards are needed that create a clear delineation between various functional layers of a highly available system. This standardization of layers—hardware, operating system, middleware and application services—is greatly facilitating the

on application development, managed services and customer support. Equipment providers require that these new applications achieve the highest levels of availability and dependability while contending with constant pressure to reduce development costs. This shift is not unique to the telecommunications market, as similar trends are evident in a variety of different markets such as aerospace & defense (A&D), manufacturing and other segments. The service providers and vendors offering highly available systems are increasingly looking to the industry to supply building blocks they traditionally have designed and developed internally. The aerospace and defense industry, particularly in the U.S., is providing a strong incentive to their prime contractors—both product suppliers and system integrators—to include as many commercial-off-the-shelf (COTS) building blocks as possible. Similar trends are also emerging in the manufacturing and financial markets. High availability is maturing and becoming something much more than a niche market serving the telecom industry.

ability of systems developers to put together highly available application-ready systems using COTS building blocks. Figure 1 shows a simple before and after visual of this industry trend. The emergence of multiple COTS suppliers for each of the building blocks is creating a robust ecosystem of COTS component suppliers. This enables system developers to focus their precious, often shrinking resources on things that differentiate them from the competition—applications and services.
Manufacturing and Industrial Applications
The evolving economics and increasing demand for HA systems can be seen rather dramatically in manufacturing and industrial applications. Recent changes in the adoption of systems and applications in the manufacturing sector have increased the need for HA capabilities. The nature of the operations in this segment is particularly illustrative of the demand and
trend toward commercial open standards HA systems. First and foremost, more and more of the factory floor itself is now based on automation of various types. While this automation takes a variety of forms (lasers, robots, etc.), all the various areas of automation end up stimulating demand and requirements for information technology to monitor, manage and control the various devices on the floor. These IT support systems have an HA requirement by their very nature. Examples include control systems on robots, machine tools and automation. In many application scenarios, the floor systems also need to communicate with each other in real time and share process data. Vendors of a variety of programmable logic controller (PLC) products are enhancing their products with Ethernet capability. This adoption of Ethernet on the factory floor will increase interdependence and risk. Designers, suppliers and management will also be workRTC MAGAZINE DECEMBER 2009

The Risk – Downtime in Manufacturing
The cost of downtime in manufacturing, already well-known before the latest wave of IT adoption, continues apace as the above trends march their way through the industry. The increased automation certainly provides increased productivity and quality, but the related systems must be highly available, or the economic benefits erode rapidly. Systems integrators and suppliers that may not have had a need to ponder HA requirements in most of their projects will now need to do so. The downtime cost for their manufacturing customers has changed dramatically, and systems integrators need to respond with new approaches to high availability. Figure 2 shows the relatively higher cost of downtime in the manufacturing industry. Given all of the above changes and increased risks, it is critical to consider the

integration of systems and an overall HAoriented architecture at the earliest stage possible. Most experienced manufacturing directors and engineers have gone through the process of “creeping integration” where they have to plumb disparate elements into a coherent system. The degree to which that integration is successful and sustainable is directly proportional to the time devoted to component selection and architecture early in the process.
Implementing High-Availability Systems
The evolving economics of highavailability systems and the increased demand for HA capabilities in manufacturing and other industries leads naturally to the question of implementation. As you consider how to get started with high availability, there are some key points to keep in mind before you get too far into the process. First, once you have decided to go the commercial-off-the-shelf (COTS) direction, hardware selection becomes the paramount consideration. In the telecom
solutions engineering
space, ATCA (Advanced Telecommunications Computing Architecture) has seen increased adoption in recent years. In particular, the “Commercial ATCA” trend shows the evolution of ATCA beyond telecommunications to other industry segments and applications. For ATCA hardware, designers should focus on: switching options, fabric capacity, configurability and thermal issues. ATCA systems offer many options for blades and also enable the use of advanced mezzanine cards (AMCs) that are hot swappable and have integrated system management functions (Figure 3). After hardware selection, there are four other key considerations as you think about the design of your HA system. The first is Platform Independence and Portability. System changes are inevitable and need to be planned for. Flexibility is important in the middleware and in applications as well as in the hardware. HA implementers are encouraged to review and adopt industry standards where possible, especially those from the Service Availability (SA) Forum. The SA Forum’s Hardware Platform Interface (HPI) specification and Application Interface Specification (AIS) are the two key standards to review for more on how to achieve platform independence and portability. System developers must also provide failover budgets in their designs. All HA systems have critical performance requirements. It is important to define the various failover scenarios early in the process. Start by classifying failover scenarios into three categories: sub 100 milliseconds, 100 to 500 milliseconds, and greater than 500 milliseconds. The technology applied will vary among the three different cases. Designs must also ensure that there is no single point of failure. Any system that is expected to provide uninterrupted service must eliminate single points of failure. This is the most critical requirement of any HA system. Redundancy of various types is needed, including: base and backplane interfaces, power/cooling, and the HPI interface to availability middleware. Your choice of availability middleware is also important in this context. GoAhead Software’s SAFfire solution is an example of availability middleware to consider as
you assess this component of your architecture. The product is based on open standards and GoAhead has a long and successful track record in the HA middleware market. Finally, the system must be upgradable. Your HA design needs to incorporate the requirement that an operational system can be upgraded as new versions of software or hardware become available— without impacting service. Designing for upgradability means that the service must be maintained during the upgrade process. Rolling back upgrades that go wrong must also be designed from the start. Overall, there is no question that the availability of COTS components helps vendors get systems to market sooner, but it also means that the above considerations must be evaluated as part of the move. Assessing these areas can help you take full advantage of the COTS trend and economics, whether your final application is a complex manufacturing scenario or another highly available application. The traditional high-availability demands of the telecommunications industry have begun to permeate many other market and industry niches. In particular, applications in the manufacturing market are driving the need for more high availability because of the unique characteristics of the segment. Developers and vendors serving these rapidly evolving markets would do well to begin designing high-availability service into their applications. GoAhead Software Bellevue, WA. (425) 453-1900.

n early 2008, the Small Form Factor Special Interest Group (SFF-SIG) introduced a ground-breaking new interconnect technology called Stackable Unified Module Interconnect Technology (SUMIT). SUMIT is a stacking, I/O-centric expansion approach that includes both highand low-speed bus signals. Two high-speed 52-pin connectors offer a wide range of serial peripheral interfaces from low to high end including USB, SPI, LPC, I2C/SMBus and PCI Express. Power is also made available on both connectors with a large centrally located ground connection. The SUMIT interface is defined around two connectors, each having unique signaling characteristics. The SUMIT-A connector, which can be used alone, includes four Universal Serial Bus 2.0 (USB) ports, a low pin count bus (LPC), System Management Bus (SMB/ I2C), Serial Peripheral Interface (SPI), and a 1x PCI Express (PCIe) link that can support an ExpressCard. The SUMIT-B connector is an optional connector that adds another x1 PCIe and either a x4 PCIe link or four more x1 PCIe links. In October of this year, the SFF-

SIG membership approved another new standard in support of SUMIT. Called “SUMIT-ISM” (Industry Standard Module), these standard modules are defined by the SFF-SIG as having “a 90 mm x 96 mm board outline plus mounting holes, without regard to bus expansion.” SUMIT-ISM takes a new approach by employing backward-compatible dimensions, I/O zones, and mounting holes to enable a flexible stacking design format.
This “ISM” size will be familiar to many as the PC/104 form factor. Since the SUMIT specification itself defines only a board-to-board interface (connectors and pin definition), the ISM specification was necessary to define how SUMIT is implemented on ISM modules. The SUMIT-ISM standard opens the door for new and more flexible combinations of I/O capabilities, bringing in high-speed serial interfaces while still supporting legacy
Industry Consortia Involved in Small Form Factors The SFF-SIG
The Small Form Factor Special Interest Group is an international organization devoted to identifying, creating and promoting standards that help electronics system and device manufacturers and integrators move to small form factor technologies and building blocks in their products, and protect their investments. Benefits of small form factor products include smaller size, reduced power consumption (eco-friendly, “green” products), and greater reliability compared to larger legacy products. The SIG’s philosophy is to embrace the latest technologies, as well as maintain legacy compatibility and enable smooth transition solutions to nextgeneration interfaces.

The SUMIT-ISM Standard Supports Flexibility
Embedded developers of long-life industrial, medical, defense and other applications are looking for a small footprint, compact dimensions, and the ability to use the multitude of existing expansion modules in use today.

modates the new high-speed devices. The SUMIT-ISM standard defines the SUMIT A and B connectors and two legacy stack types, one using slotted mounting holes. This enables SUMIT-ISM modules
to be designed to support the SUMIT connectors as well as legacy ISA (PC/104 form factor) or PCI (PCI-104) interfaces. By rotating the ISM module 180 degrees as necessary, the module can fit either legacy bus type, while still maintaining the SUMIT interface. This is important because many embedded designs begin with the required I/O, not the CPU. Since the I/O drives the bus requirements, then the CPU requirements, it makes sense for the designer to start with the most unique I/O and then work backwards to a standard CPU. As embedded designers seek higherperformance systems and need to incorporate growing numbers and types of I/O into legacy designs, SUMIT-ISM supports this approach by allowing for a flexible modular stack that can accommodate a variety of new high- and low-speed serial buses while maintaining compatibility with either the legacy ISA or the PCI bus. The PC/104 and PCI-104 buses have gained worldwide adoption as industry standard system expansion interfaces for small, modular systems. SUMIT-ISM was conceived to support the ISM concept, which provides compatibility with many different boards that are available in the 90 mm x 96 mm industry standard footprint. SUMIT-ISM defines “Legacy Type 1” and “Legacy Type 2” options for designers wishing to incorporate PC/104 or PCI-104 modules and enclosures into their system. A Legacy Type 1 board supports the legacy 104-pin PC/104 connector in addition to the SUMIT-A and/ or SUMIT-B connectors. A Legacy Type

2 board supports the legacy 120-pin PCI104 connector in addition to the SUMITA and/or SUMIT-B connectors (note the Legacy Type 2 mounting slots due to the PC/104 offset mounting holes). In this way the SUMIT-ISM specification can maintain legacy applications while supporting newer, high-speed serial buses (Figure 2). The SUMIT-ISM specification supports: • Expansion interfaces decoupled from form factors
• Defined connector expansion areas • Flexible expansion buses and I/O interfaces • Top- and bottom-side component height restrictions • Previously undefined and unnamed bus combinations The stacking order for the SUMIT-ISM modules is also a significant feature of the specification. The stack is assembled in one
direction only, which is “up” from the processor board (SBC), defined as the bottom board in the stack. This one direction stacking requirement is a result of the point-topoint nature of USB and PCIe interfaces. I/O cards “consume” a USB or PCIe resource and shift the remaining links for use by I/O modules above them. If a Legacy Type 1 or 2 parallel bus is incorporated on the CPU, the legacy bus, being a non-point-to-point parallel bus, may stack in either direction. Due to I/O cards consuming and lane shifting of the serial bus resources, some attention must be paid to the actual module stacking order. The resources provided by the base CPU board must also be taken into account. A full set of resources is not a requirement on a SUMIT connector. A label containing a resource table is defined in the SUMIT specification to convey this interoperability information (Figure 3). As with the above definitions for Legacy Type 1 and Type 2, the incorporation of the SUMIT interface basically replaces either the 120-pin PCI or the 104-pin PC/104 connector with a 104-pin SUMIT connector pair. None of the dimensions, I/O zones, or mounting hole locations on “stackable” form factor boards (EPIC, EBX or PC/104) need to change, other than the use of slotted mounting holes when SUMIT Type 2 is the primary expansion format. The use of SUMIT-ISM results in greater I/O interface options and higher potential bandwidth, while requiring far less real estate for the connectors. Keeping the same form factors, and updating only the interfaces, lets form factor standards and interface standards evolve separately. When a new form factor becomes available, it can support all of the required interfaces. This helps minimize revisions to the specifications and increases the platform’s longevity. Plus, the signals provided by the new SUMIT connectors align well with new low-power chipsets, for example the Intel Atom and VIA Nano microprocessor families. To date, three SFF-SIG member companies, VersaLogic, WinSystems Inc. and ADLINK/Ampro, have all recently announced CPU and/or I/O products designed using the SUMIT or SUMITISM specifications from the SFF-SIG.

as an abstraction or indirection layer that sits between “guest” software and underlying silicon. The abstraction provided by virtualization to each virtual machine running over it is that of a 100% dedicated CPU and memory address space. This abstraction is not a “heavy” one as with Java virtual machines or emulation, where software implements all program execution at the instruction level. With embedded virtualization, guest software runs natively on physical CPUs and occupies physical memory. However, execution of guest OSs and other software occurs in non-privileged “user” mode, with the hypervisor mediating access to and allocation of physical resources, including CPU cores. When consolidating legacy multi-CPU or multi-board designs onto a single multicore CPU, it is very tempting to dedicate available cores, statically, one by one, to legacy CPU equivalents. A key advantage offered by embedded virtualization is the ability to perform this allocation dynamically, on an as-needed or policy-driven basis. Rather than direct association of OS-to-core, the abstraction provided by the hypervisor assigns one (or more) virtual cores to each hosted virtual machine (VM), and provisions those virtual cores with access to physical ones, as needed, similar to SMP operation in multiprocessing OSs like Linux as shown in Figure 1. The benefits of this abstraction for multicore systems are manifold. A multicore design offers better utilization of available cores and memory. The ability to flexibly map hosted software to available silicon means that many guest OSs can be assigned to one core or one guest OS to multiple cores, and arbitrary points between. It also provides the ability to isolate guest OSs and application stacks running in shared physical memory. Moreover, because embedded virtualization is lightweight in
Let’s examine the most salient use cases for embedded virtualization in multicore systems. For one thing, they make it easier to optimize the use of the available computing power through resource management, load balancing and energy management. Embedded virtualization also makes possible secure partitioning and the ability to enable legacy software to run in a multicore operation as well as to shield already verified code from the need for tweaking to address product line variants. Most operating systems, in the enterprise, on the desktop and in embedded systems, aren’t very good at resource management. If they were superior resource managers, data center virtualization would be a non-event. The resources in question can include memory, devices and, importantly for multicore processors, the cores themselves. OSs (in particular embedded OSs) make static guesses about resource allocation and use. When those guesses prove inadequate, remediation occurs through brute force mechanisms like reapers, which kill off running processes and threads to save memory and CPU. Or remediation may not happen at all, resulting in thrashing and lock-up. The growing size and complexity of software and hardware beg a better solution. Rather than attempt to “fix” legacy OSs, one by one, virtualization provides the right locale, outside the scope of those OSs, to manage resources and to allocate them more efficiently to hosted virtual machines. Load balancing refers to techniques and mechanisms used to distribute the workload across two or more CPUs, network interfaces, hard drives, or other resources. The term is current in data center computing, but with the advent of multicore and multi-interface intelligent devices, the notion also applies to embedded design. As in data center computing, embedded virtualization provides new opportunities to optimize resource utilization, maximize throughput, minimize response time and avoid overload. Load balancing is called out by standards and requirements for high availability, like Foundation Carrier Grade Linux and SCOPE Alliance specifications. While the “heavy iron” systems addressed by these tomes usually run on blades, the same principles extend to more deeply embedded systems, where building on multiple redundant components, combined with load balancing, can increase both reliability and performance. In blade-based systems, each CPU is provisioned with its own memory, cache, peripherals, etc. In multicore systems, those divisions are imposed artificially: all CPUs live in a single package and share L2 cache, main memory, peripherals, etc. That fact notwithstanding, simplistic approaches to multicore software design—static assignment of OSs to specific cores—today prevail in embedded systems software, and miss opportunities for optimizing resource utilization. Key to load balancing in systems of any size is the ability to RTC MAGAZINE DECEMBER 2009

migrate compute loads across compute resources, including CPU cores. Only real virtualization, implementing dynamic mapping of virtual CPUs to physical cores, is up to the task of effective load balancing. Once a system employs virtualization, energy management becomes largely a case of load balancing. With multicore designs, the most effective (and obvious) way of reducing energy consumption is to shut down cores after migrating their loads to other available peer CPUs, migration that is difficult or impossible with static OS-CPU assignment. A hypervisor facilitates energy management by being “in the right place,” with system-wide knowledge of hardware resources. By contrast, the operational scope of application OSs and RTOSs prevents them from effectively implementing energy management beyond the code running on them. Gains from putting cores to sleep far exceed those possible by other means such as dynamic voltage and frequency scaling (DVFS). This advantage over DVFS will become even more pronounced in the future. With process advances, ever-smaller core voltage reduces the energy-savings potential of DVFS due to smaller deltas. Conversely, the proliferating number of cores offers immediate energy-saving potential. A real-world example of energy can be shown by a mobile device design that could include different subsystems. One, a performance-intensive subsystem such as a baseband modem stack requires the compute capability of two cores when load is high, but never more than 0.2 cores for lesser loads. On the same device, a design includes a multimedia stack needing up to four cores at full load, but the load falls to zero if no media is displayed. Accompanying these loads is an application OS and UI stack that use between half and two cores while user interaction takes place, and near zero when idle. When the user is navigating through menus, only about 2/3 of the compute power of one core is required, yet there are multiple OSs involved. Without virtualization, the design would need to run on at least two cores, each at half throttle or less. With virtualization, all operations can consolidate on a single core, and the overall energy use of the single core will still be less than the combined energy gobbled up by two cores running on low throttle. The additional cores are not wasted. They are immediately available—minus some very small power-up latency—when the user invokes compute-intensive multimedia operations or an in-coming call launches a ring tone. The reality of globally shared memory in multicore systems presents challenges to security regimes and opportunities for exploitation. As embedded software becomes larger and more complex, both OSs and software stacks, from their sheer size and the effort required to create and maintain them, accrue bugs and security holes. In a shared memory design, even if OSs are allocated to dedicated CPUs, a break-in on one could lead to systemwide compromises. Embedded virtualization, as implemented by hypervisors, ameliorates these risks on two levels. First, it isolates guest software and strongly regulates inter-guest communication by limiting sharing of global objects and through IPCs with strict access protocols. Second, it treats all guest software as untrusted,

with limited access to critical resources, including other cores, memory, devices and privileged instructions. The Trusted Computing Base (TCB) of an application can then be limited to the application itself, the hypervisor, and the underlying hardware. Removing a complex operating system like Linux from the TCB makes it much smaller and therefore much easier to verify with respect to correctness. Application OSs, like Linux and Windows, have been SMPenabled for several generations of those platforms. As such, they can already leverage multiple available CPUs in a multicore system. The majority of embedded OSs—RTOSs, executives, etc.— are ill-equipped to run on more than a single core, requiring that multiple copies of those systems run on multiple cores to take advantage of multicore silicon. This limitation can raise deployment costs by doubling or trebling run-time fees, one for each copy of the OS running on a unique core. It can also consume system resources when legacy embedded OSs cannot share code images, stacks, buffers and other objects across cores and shared memory. In addition, it can slow development by forcing developers to break apart running legacy stacks, assign the pieces to two or more RTOS instances, and to implement and debug IPCs among them. Through the abstraction of virtual CPUs, embedded virtualization can enable legacy embedded OSs for multicore operation. The legacy OS, in a hosted virtual machine, “thinks” it is running on a single physical CPU, while the hypervisor can spread the operation of the OS and applications running on it across two or more available CPU cores. The insertion of a hypervisor, however, does not magically confer SMP operation on a legacy RTOS. Designers and integrators must still consider synchronization and concurrency. OEMs can also look to virtualization to mask variations in actual bills-of-material (BOMs) from system and application software. In lines where some products use processors with fewer cores than others—for example, in entry-level designs vs. higherend devices—a hypervisor allows the same software architecture to apply across all products and BOMs. This is not the case if OSs and applications are tied directly to physical cores. As multicore CPUs become mainstream in embedded designs, virtualization offers an attractive tool and platform for exploiting available CPU cores and computing horsepower they provide. In fact, embedded virtualization actually simplifies and optimizes utilization of multicore silicon. In particular, virtualization provides an efficient, low-overhead abstraction for mapping and allocating available cores onto hosted software, enabling the rich mix of software stacks that characterize today’s connected, converged device designs.

System Integration Unleash the Power of Multicore Pthreads is supported by Linux, UNIX, and a wide range of embedded operating systems such as Integrity, LynxOS and QNX. Even Windows supports a POSIX interface. Due to the ubiquity of POSIX, there exists a very large base of application code that can be reused for embedded designs. Another strong advantage of POSIX is that independent conformance validation is available from the Open Group. There are a large number of POSIX implementations that have been certified conformant to the latest POSIX specification. By programming to the POSIX API, developers can write multithreaded applications that can be ported to any multicore platform running a POSIX-conformant Multicore processors offer great potential for increased operating system.

modifications. SMP is now quite common in embedded operating systems. For example, Linux, Green Hills’ Integrity and Intel VxWorks all support SMP. One of the challenges with SMP is the fundamental difference in scheduling behavior relative to unicore real-time systems. Because multiple processes may be running concurrently, the use of process priority to guarantee execution time may not be sufficient. Green Hills’ Integrity operating system provides an optional alternative approach in which application processes can be assigned guaranteed percentages of execution time across all cores in the system. Within an application, threads are prioritized using standard priorities and time slicing. Maximizing cache usage is critical to the performance and power profile of most embedded systems. Most SMP systems consist of cores that have independent on-chip caches. When a thread migrates from one core to another, the cache locality of the thread’s code and data is lost and must be reloaded on the new core. When a thread needs to run (such as when it is the highest priority runable thread), and more than one core is available (idle), the SMP operating system must intelligently choose which core to use. The operating system should keep track of a thread’s natural affinity. The natural affinity of a thread is defined as the core on which the thread last executed. Assigning threads to the cores that match their natural affinity minimizes migrations and cache misses and the embedded software will exhibit superior performance and power efficiency. User-defined affinity is another useful tool for developers, which enables specific threads to be bound to specific cores. La-

use of inter-processor interrupts (IPI), which increase latency. Another scenario involves assigning multiple threads cooperating to fulfill a particular job (e.g. using shared data structures) the same core affinity, again to minimize IPIs and maximize cache utilization. The SMP operating system typically provides a system call to assign core affinity. Multicore processors such as the Freescale P4080, Intel Core2 and ARM Cortex A9 provide some form of hardware virtualization acceleration. Multicore architectures can improve the usability of hypervisors. For example, on a dual-core system, a separate virtual machine can be bound to each core, enabling a guaranteed quality of service for each guest. Using an enhanced Type-1 hypervisor (Figure 1), real-time applications can be assured optimal response time by executing on a core independent of guest operating environments. Another use case for multicore hypervisors is the ability to provide more flexible power management. Guest operating systems can execute on all system cores when applications require maximum CPU availability. However, because the hypervisor can map guests to virtual cores, the guests can be executed on a smaller number of available cores when there is less work to do, enabling the remaining cores to be fully powered off. The proliferation of multicore devices is likely to increase the proliferation of hypervisors: symbiotic growth for two disruptive technologies.
Multicore Debugging Tools
Multicore processors often provide a single on-chip debug port such as JTAG that enables a host debugger, connected with a hardware probe device, to debug multiple cores simultaneously. With this capability, developers can perform low-level, synchronized run con-
system integration
trol of the multiple cores. Board bring-up and device driver development are two common uses of this type of solution. For efficient use of this multicore hardware facility, the development tool must enable the developer to visualize all the cores of the system and choose any combination of the cores to debug, each optionally in its own window. At the same time, the tool must provide controls for synchronized running and halting of the debugged cores. With run-mode debugging, the cores are never stopped. Rather, the debugger controls application threads using a communications channel (usually Ethernet) between the host PC and a target-resident debug agent. For efficient use of this facility, the operating system must provide an integrated debug agent (and the associated communications device drivers) that is operating system aware and provides flexible options for interrogating the system. For example, the operating system should come with a debug agent that communicates with the debugger to provide the capability to debug any combination of user threads on any core, regardless of the homogeneity of the core architecture. The user needs to be able to set specialized breakpoints that enable user-defined groups of threads to be halted when another thread hits the breakpoint. Some classes of bugs require this fine-grained level of control. To be able to halt threads on a core separate from the core running the thread that hits the breakpoint, the operating system must handle all the behind-the-scenes communication that informs the appropriate core, with minimal latency, of the event. Many operating system vendors provide an event analysis tool. The event analyzer is an indispensable tool for developers of multithreaded software because it makes it easy to understand system Untitled-6 behavior and locate performance bottlenecks, livelocks, or other problems. A target-resident agent logs important operating system level events, such as service calls, interrupts, context-switches and user-defined events. The tool uploads this event log (either during execution or post-mortem), and displays the events in a timeline. The tool allows the user to zoom, select specific events for further information, generate execution statistical reports, and other functions. The event analyzer is even more critical for a multicore design. The event analyzer must be able to show events for all threads on all the cores, with the event streams synchronized to the same time scale. The tool must be able to display IPC between the cores. Green Hills Softwareâ&#x20AC;&#x2122;s EventAnalyzer product is one example of a tool that meets these requirements. There can be little argument that embedded designs are going multicore. These systems are more complex to develop, manage and debug. To meet these needs and help designers realize the performance benefits of multicore without losing time-to-market, systems software must meet a challenging set of requirements. Vendors must provide tools that aid in the portability of multithreaded code, operating system and virtualization features that make it easier for application software to be allocated efficiently across multiple cores, and development tools that provide complete visibility into and control over the distributed software.

S4-AMC Altera® Stratix® IV GX Reconfigurable AMC
Recent years have seen much chaos and confusion in the COTS world. Changing from the safe and wellknown world of parallel buses to the ‘wild-west’ of serial interconnects has been extremely difficult for most COTS users and standardformat system designers. BittWare saw that the days of parallel buses were behind us a while ago; therefore we’ve been hard at work climbing the learning curve. High-speed serial interconnects open up new possibilities for architecting signal processing systems, and BittWare has taken advantage of this with our latest AMC and VPX boards featuring Altera’s FPGAs.
• High-density Altera® Stratix® IV GX FPGA
FPGAs enable our boards to adapt to these new and emerging formats while leveraging a single, welloptimized common architecture. FPGAs are also the latest, and arguably most powerful, addition to the signal processing toolbox. However, like the parallel to serial interconnect transition, using FPGAs to process signals is a shift from using programmable DSPs. Our ATLANTiS™ FrameWork eases this shift by providing fully validated physical interfaces to I/O and memory, data moving engines, resource arbitrators, and many other low-level modules, along with standard dataflow and control fabrics that allow modules to be easily connected, coordinated, and controlled. This FrameWork greatly simplifies the implementation of complex signal processing solutions on FPGAs, significantly reducing the time required to deploy FPGAs in embedded signal processing systems. The new serial formats, and our FPGA-based boards which support them, are fueling a new cycle of innovation for system design. I think we’ll see some great ideas and applications emerging in 2010.

most complex of applications. However, the presence of multiple processing cores on one physical chip complicates the design process considerably. So far, most commercial compilers have not advanced to the level of being able to automatically analyze which sections of code can run in parallel. That has forced embedded designers looking to take advantage of multicore processors to make use of parallel programming APIs that add overhead to code and are difficult to debug. In addition, traditional sequential programs make it very difficult to visualize parallel routines, creating a big problem for designers inheriting legacy code or struggling with their own complex applications. If todayâ&#x20AC;&#x2122;s parallel programming is difficult for designers, imagine how it will be when the next generation of processors with 16 or more cores arrives. The trend toward multicore processors and massively The most obvious solution to this challenge is using better programming tools and parallel architectures is just beginning.

combination of existing ASICs, or run signal processing code on a considerably slower processor in software. FPGAs have been a game changer. Now, you can simply download custom signal processing applications to an FPGA and run in hardware, at a cost of only tens of dollars. In addition, because FPGAs implement your embedded applications in hardware, they are by nature massively parallel. With all of these advantages, it is important to make better use of FPGAs in embedded designs, and develop in less time. One major challenge embedded developers face is the difference in design tools used to program FPGAs and microprocessors. While many developers are comfortable writing high-level C code, at least for sequential microprocessor applications, FPGA programming is typically done in a hardware description language (HDL) such as VHDL. This fundamental gap in communication between developers, which is tantamount to speaking different languages, can add a major hurdle in the development cycle, especially when FPGAs and processors are both used in a single design. To solve this problem, a number of tools, such as Impulse CoDeveloper, have been developed to translate C applications into HDL code. These kinds of tools enable you to specify applications at a high level and then target those applications to FPGAs. In addition, graphical dataflow languages such as LabView allow you to develop for FPGAs without specific HDL knowledge. Because dataflow provides an inherently parallel approach to programming, it also allows you to automatically take advantage of the massively parallel nature of FPGAs. The message here is simple: using high-level FPGA design strategies, such as dataflow languages and C to HDL translators, can maximize the efficiency of your design team and reduce your time-to-market.

Figure 1 Using a dataflow language such as LabView can speed development of parallel embedded applications.
Finally, one of the most recent technologies to enter the embedded scene is virtualization. The main idea behind this technology is to make better use of processing hardware by abstracting away the details of the specific hardware platform from operating systems and applications. Specifically, one way to use virtualization in embedded designs is to install a piece of software called a hypervisor, which will allow multiple operating systems to run
in parallel simultaneously. This ends up having positive implications on both the overall capability of an embedded system and its use of multicore hardware. In a system with multiple homogeneous processor cores, a hypervisor makes it easy to construct an AMP software architecture where individual operating systems are assigned one or more cores. At a high level, you can think of virtualization technology as making your multicore hardware multitalented (Figure 2). App

Figure 2 Installing a hypervisor enables asymmetric multiprocessing (AMP) on a set of homogeneous processor cores.
Though designers often program entire embedded systems from the ground up, pressure to reduce development timeâ&#x20AC;&#x201D;and therefore costâ&#x20AC;&#x201D;has led to higher usage of operating systems in the embedded domain. This, however, presents a problem: how do engineers balance the need for the services and user interface provided by a commercial OS with the real-time performance needed for an embedded application? Imagine, for example, that you are designing a medical imaging machine. How can you take advantage of the built-in UI capabilities of an OS such as Linux while processing imaging data in real time? Using a hypervisor can meet these challenges. Running both a feature-rich commercial OS and a real-time OS in parallel can reduce development time for your embedded applications while maintaining determinism. Though trends in embedded technology including multicore processing, FPGAs and virtualization present a big departure from traditional development techniques, there are some clear steps that you can take to harness them and stay competitive. First, adopt programming tools that abstract away hardware features such as multiple processing cores or FPGA gates. By concentrating on implementing your design while spending minimal time making adjustments for the underlying hardware architecture, you can bring your embedded products to market faster. Programming environments with parallel debugging features, new parallel programming APIs, dataflow programming, and C to HDL converters can all help you achieve these goals. In addition, employing virtualization enables you to take advantage of both real-time processing and commercial OS services to reduce development time and make the most of your multicore hardware. As the next generation of embedded systems grows more powerful than ever, taking advantage of these latest technologies will help your company stay ahead of the curve.

Low-Power, Configurable Touch-Sensing Controller Adds Auto-Calibration
A new line of capacitive touch-sensing devices features low-power 1.8V operation to extend battery life in handheld mobile consumer applications. The CY8C20xx6A CapSense devices from Cypress Semiconductor replace mechanical buttons and sliders, offering attractive, functional interface options for designers. The new family also offers improved response time with the most precise scanning of any CapSense devices. With superior immunity to conducted and radiated noise, as well as robust waterproofing, the new devices also enable reliable touch-sensing operation in applications such as white goods, home appliances, printers, computers and TVs/monitors. The CY8C20xx6A devices have up to 36 general-purpose I/Os (GPIOs) to implement multiple CapSense interfaces. Leveraging the PSoC programmable system-on-chip architecture, a single new CapSense device can also manage functions such as motor control, intelligent sensing, LED control and more—a capability called CapSense Plus. Additionally, the new devices include a full-speed USB interface. The easy-to-use CapSense devices allow customers to bring products to market quickly. The CY8C20xx6A device line is available in multiple configurations and packages, including a small form factor 3x3x0.6-mm 16-pin QFN. Additionally, the CY8C20xx6A family offers the new SmartSense solution, which automatically calibrates capacitive-sensing parameters during the design process, cutting days of development time. While existing solutions require engineers to perform time-consuming calibrations for up to 15 capacitive-sensing parameters, the new SmartSense solution from Cypress Semiconductor, developed for its CapSense devices, sets these automatically during the design process, significantly reducing development time. The SmartSense capability greatly simplifies the replacement of mechanical buttons and sliders, allowing designers to create a single platform for multiple industrial designs without having to manually optimize performance for each design. Engineers can simply incorporate the SmartSense firmware using the PSoC Designer embedded design tool and instantly develop touchsensing interfaces that provide reliable operation over a wide range of capacitance values. This eliminates the need to retune a design each time the thickness or material used for the interface overlay changes, reducing time-to-market and saving development costs for customers. Furthermore, the solution ensures that manufacturing variations in PCBs, overlays and changes in noise environment are automatically calibrated out. The new CY8C20xx6A CapSense devices are supported by the CY3280-20X66 CapSense Development Kit, which includes a development board with ports for the following Plug-in Modules: • CY3280-SLM – Linear Slider Module • CY3280-SRM – Radial Slider Module • CY3280-TPM – Trackpad Module • CY3280-BSM – Simple Button Module • CY3280-BMM – Matrixed Button Module • CY3280-BBM – Breadboard Module Each package option of the new low-power devices is also supported by a CY3250-20xx6 ICE Pod Kit that includes emulator pods and feet, enabling a designer to perform system-level debugging.

DSP-Based Servo Motion Controllers with Full Closed-Loop Control
Two DSP-based servo motion controllers handle three or six axes of control. The PCI-8253 (three axes) and PCI-8256 (six axes) from Adlink are designed to take full advantage of the latest digital signal processing technologies to provide a Âą10V analog motion controller with full closedloop control, a PID plus feed-forward algorithm and 20 MHz encoder input frequency. The PCI-8253 and 8256 not only provide general motion control functions, but also support comprehensive and application-specific functions suitable for automated optical inspection (AOI), gantry and manufacturing machine applications, as well as complete compatibility with all the top third-party servo drivers in the market. By incorporating a digital signal processor (DSP), the PCI-8253 and 8256 are able to provide advanced, flexible and comprehensive motion functions that cannot be achieved through ASIC-based solutions. Such functions include multiple dimension interpolation and high-speed position comparison. All motion profile algorithms are developed by Adlink and implemented on the DSP. Therefore, application-specific functions can be custom developed for customers. By incorporating FPGA technology, the PCI-8253 and PCI-8256 provide higher motion control performance by a fast encoder input frequency up to 20 MHz. In addition, the hardware-based high-speed position comparison and trigger output speed of up to 1 MHz further make the PCI-8253/8256 ideal for AOI applications. The PCI-8253 and PCI-8256 also offer a point table that supports over 5,000 points for each axis, ideal for contouring applications. Setup and deployment of the PCI-8253/8256 are simplified through Adlink's MotionCreatorPro 2, a user-friendly Windowsbased application development software package. Axis servo gains (PID plus feed-forward gain) can be easily tuned through this tool, which greatly reduces the amount of effort spent on gain tuning. A sampling window also provides a real-time display of the motion data enabling simpler integration of axis parameters, PID gain and other on-the-fly changes. The PCI-8253 and PCI-8256 are currently available for a list price of $1,329 and $2,129, respectively. ADINK, San Jose, CA. (408) 360-0200. [www.adlinktech.com].
Multi-Channel Gigabit Ethernet Data Recorder Supports 500 Mbytes/s
A fixed-featured off-the-shelf multi-channel Gigabit Ethernet (GbE) streaming data recorder system is designed for demanding sensor-to-processor streaming data applications. The Vortex SDRxE from Curtiss-Wright Controls combines a uniquely equipped 3U controller with a reliable, scalable storage subsystem. This rack-mountable data recorder can record up to four channels of GbE data at 125 Mbytes/s per channel. The Vortex SDRxE speeds the integration of high-speed data recording and data logging capabilities into subsystems designed for instrumentation recording, mission recording and SIGINT/ELINT recording applications. The Vortex SDRxE enables high-volume, continuous streaming recording of GbE data. Its flexible storage design enables system integrators to add one or more Vortex SBOD or RAID storage systems as needed for their applicationâ&#x20AC;&#x2122;s required recording duration. A wide range of Vortex storage options includes a 3U SBOD with 16 Fibre Channel (FC) disks, the compact 2U RAID that houses 12 SATA or SAS disks, and the 4U RAID that supports up to 48 SATA or SAS disks. For extreme applications requiring rugged storage, the Vortex SANbric system supports rotating FC disks. The Vortex SDRxE supports the special data storage methods required by streaming GbE-based sensor-to-processor applications. Captured GbE data is striped across multiple FC disks in an SBOD to ensure uninterrupted recording. Because Vortex storage technology bypasses the file system, it provides total control over data storage and enables high-speed data access via FC from other computers using heterogeneous operating systems. The Vortex Graphical User Interface (GUI) controls the recorder. This GUI is fast to learn and easy to set up. After selecting a few parameters, a record or playback session is initiated by simply pressing the corresponding button. Accurate time-stamp for playback of critical data Vortex data recorders feature the unique RapidReplay hardware system that enables the SDRxE to capture and time-stamp incoming individual GbE data frames at full GbE line rates prior to storage. This extremely accurate time-stamping enables the precise data playback, via the GbE channels, needed for detailed post analysis. Time-stamped data is transferred via Fibre Channel (FC) to an external Vortex 3U SBOD (or RAID). With sixteen 450 Gbyte FC disks, a single SBOD provides 7.2 Tbytes of storage. With four channels of 125 Gbyte/s GbE data, the Vortex SDRxE can support nearly 4 hours of recording time. To increase record time only requires the addition of another SBOD. Highly reliable enterprise class, FC disks are designed for 24/7 service with MTBF of >1,600,000 hours. Curtiss-Wright Controls, Dayton, OH. (937) 252-5601 [www.curtisswright.com].

USM-Based Dual Fast Ethernet PMC Offers FPGA Flexibility
A new Dual Fast Ethernet PMC is based on the Universal Submodule (USM) concept that implements a board's desired functionality through one or more IP cores in an FPGA. The corresponding line drivers are located on the main USM module, which simply plugs into the respective base mezzanine. In the P511 PMC from Men Micro, the Ethernet functionality resides on an IP core in the onboard FPGA. For this reason, the PMC provides exceptional design flexibility, because the IP core is easily updated and changed. This helps designers quickly turn individual I/O requirements into production-ready products, reducing design time and costs. The new P511 PMC is suitable for a variety of mission-critical applications found throughout the telecommunications, industrial, medical, transportation and aerospace industries. The Ethernet interface includes two 10/100Base-T Ethernet channels featuring half and full duplex operation accessible on two channels via two RJ45 connectors routed to the front of the board by an adapter cable from an SCSI connector. The P511 can buffer all receive and transmit Ethernet frames either locally or in an external buffer for traceability and error analysis. Up to six GPIO lines can be used on the module for additional functionality. Alternate gateways can be constructed by combining an Ethernet core and a fieldbus interface. The 32-bit/33 MHz P511 is suitable for use with any PMC-compliant host carrier board in any bus system such as CompactPCI, VME or other stand-alone SBCs (single board computers). The PMC is fully integrated to comply with IEEE802.3, features a 1,500 VAC isolation voltage and can withstand an extended temperature range of -40° to +85°C. For extremely dusty or humid environments, an optional conformal coating is available.

PCI Express Gen 1.x, 2.0 and 3.0 Decode Annotation Speeds Validation and Debug
PCI Express Decode Annotation, which is available on a wide range of oscilloscopes from LeCroy, provides new capability for hardware and system engineers to simultaneously understand the physical layer and protocol behavior of high-speed PCI Express serial data signals. The new capability provides a link layer protocol decode for up to four PCI Express signals annotated on the oscilloscope physical layer waveform. Combined with LeCroy’s 8b/10b decode annotation tool (a separate option), simultaneous symbol/primitive and protocol level understanding can be achieved. For faster time to insight, all the standard math, measure, cursor, zoom and other analysis tools available in the oscilloscope may be used concurrently. The new PCI Express Decode Annotation capability has widespread application for all versions of PCI Express. It is especially helpful for the emerging PCI Express Gen 3.0 standard, where new silicon physical layer (PHY) links are beginning to be validated before the standard has been finalized. In the early PHY validation stages, the physical layer signals may not exhibit the desired signal fidelity, and a significant amount of physical layer debug must often occur before a specialized protocol analyzer can be used. In addition, it can be difficult to time correlate protocol analyzer and oscilloscope captures; therefore, interpretation of the information from the two different tools could be more time-consuming and more error prone. By providing the decoded information as an annotation on the physical layer waveform within the oscilloscope, the protocol and physical layer information is synchronized, and permits easy scrolling and review of the captured data, as is often necessary. Thus, interpretation is easier, faster and more reliable in the early PHY validation stage. The initial data rate for decoding may be set to the common 2.5, 5, or 8 GT/s. PCI Express Gen 2.0 and Gen 3.0 begin handshaking at lower bit rates, and once the link is established, increase to their maximum data rate. The decode algorithm recognizes the different bit rates and decodes appropriately, and supports modes with and without scrambling enabled. Advanced algorithms deconstruct the waveform into protocol information, and then annotate the physical layer waveform on the oscilloscope grid. Decode annotation condenses or expands depending on the time base/zoom ratio setting. Various portions of the protocol are colorcoded for intuitive, quick visual understanding of the protocol behavior and easy visibility, even with long acquisitions. For instance, TS1 and SKIPs are color-coded a grayish blue while Electrical Idle, Error, or Unrecognized frames are color-coded red. Other message types are uniquely color-coded. To support the large installed base of LeCroy users, the option is available on a wide range of oscilloscope models with real-time bandwidths from 2.5 GHz to 30 GHz supporting the full range of PCIe users, from Gen 1.x to 3.0.

PCI Express 48-Channel Digital I/O Card with Change of State Detection
A 48-channel PCI Express (PCIe) card has been designed for use in a variety of digital I/O applications. The PCIe-DIO48S is compatible with 8255 PPI (mode 0), making it easy to program and migrate from other Acces PCI digital I/O cards. The card features a x1 lane PCI Express connector that can be used in any x1 or higher PCI Express slot. The PCIe-DIO48S is suitable for use in application sensing inputs such as switch closures, TTL, LVTTL, CMOS logic and controlling external relays, driving indicator lights and more. Each I/O line is buffered and capable of sourcing 32 mA or sinking 64 mA. Since the PCI Express x1 connector does not have sufficient power to drive this many channels, Acces provides an onboard Molex PC-style connector compatible with system power supplies (for disk drive power), to externally provide maximum 5V current sourcing capability. Connections to the card are made via two industry standard, 50-pin headers. Each header has three 8-bit I/O ports designated A, B and C. Each port can be programmed as inputs or outputs. Change of State (COS) detection and interrupt capabilities are designed to relieve software from polling routines that can consume valuable processing time. Each port can be programmed for detecting state changes on their lines. An ISR (interrupt service routine) then reads the port to determine which bit changed state and clear the interrupt. The card is supported for use in most operating systems and includes a free DOS, Linux and Windows 2000/XP/2003/Vista/7-compatible software package. This package contains sample programs and source code in Visual Basic, Delphi and Visual C++ for Windows. Also provided is a graphical setup program in Windows. Linux support includes installation files and basic samples for programming from user level via an open source kernel driver. ACCES I/O Products, San Diego, CA. (858) 550-9559. [www.accesio.com].
PCI Express Digitizer Capable of Sustained Recordings over 1.2 Gbytes/s
A new high-speed digitizer in the form of an advanced wideband and high dynamic range A/D board captures signal frequencies up to 200 MHz, when using the programmable gain amplifier in 1 dB steps for maximum gain attenuation flexibility. Frequencies go up to 400 MHz if the direct transformer coupled connection is employed for the cleanest possible signal path to the ADC. The PX14400 from Signatec includes 1 Gbyte of onboard memory configured as a large FIFO and a PCIe x8 bus to ensure it can continuously sustain long recordings at over 1.2 Gbytes/s through the PCIe x8 bus to PC disk storage without any break in the analog record. Of the two embedded Virtex-5 FPGAs, one is expressly available for custom in-line signal processing. As a Xilinx Alliance Program partner, Signatec created standardized data and control interfaces that are customer accessible along with VHDL source code examples that demonstrate the use of these interfaces to simplify real-time processing tasks through its optional firmware development kits. Up to five PX14400 boards may be interconnected in a Master/Slave configuration via a ribbon cable that connects at the top of the board. In this configuration, clock and trigger signals from the Master board drive the Slave boards for synchronized sampling across all boards. Additional boards can be synchronized, even across computer chassis, when using Signatec’s Sync1500-6 product. The PX14400 supports single shot, segmented and pre-trigger triggering modes. In Segmented Mode, “time stamps” allow for storing the time relationship between the memory segments. Time stamps are 64-bit timer values with a clock resolution of 5.0 nanoseconds, and are accumulated in a 2048 element FIFO memory separate from the data. If necessary, time stamps may be read during acquisition in order to prevent overflow. This is possible in any acquisition mode. Signatec, Newport Beach, CA. (949) 729-1084 [www.signatec.com].

2-Channel Synchro/Resolver Interface Boards for PowerDNA Cube and PowerDNR RACKtangle
A pair of boards is available in two models for a wide range of rotational position or motion applications. The DNx-AI-255 synchro/resolver interface boards from United Electronic Industries are for use with UEI’s PowerDNA Cubes and, in another form, for rack-mounting in a PowerDNR RACKtangle or HalfRACK chassis. Multiple operating modes ensure compatibility with all standard sensor wiring and excitation configurations. Each board has two fully isolated, synchro/resolver channels with independent A/D converters, and each channel offers 16-bit resolution, ±2.6 arc-minutes accuracy, and scan rates up to 4000 Hz. A key feature of the new boards is the ability to operate either as a synchro/resolver input interface or as a simulation output device on a per channel basis. Each of the channels may be configured either as a synchro/resolver input with internal or external excitation or as a synchro/resolver simulated output. Each simulated output may be used as a software-controlled input stimulus for an avionics test system or flight simulator.

Executive Letter by Steve Cooper President and CEO, One Stop Systems During the “slowdown” of 2008/09, One Stop Systems has been feverishly innovating new technologies and product offerings. Our feeling is that just because the economy is slow, that doesn’t mean that technology cannot make significant advances. With this aggressive attitude and investment, we believe One Stop is well positioned to take advantage of an improving market climate in 2010. We are particularly excited about the growth prospects in three areas: • PCIe over Cable • New innovations include the upgrade to x16 connections at Gen 2 speeds. This provides 80Gb/s bandwidth over a cable. This technology enables many applications where the amount of I/O, compute power or flash memory exceeds the space available in a single chassis. • Two applications that are enabled by the latest PCIe over cable innovations include GPU-based computational acceleration systems and solid state disk appliances based on native PCIe flash cards. • Telecommunications Servers: • The latest generation of CPUs, memory and disk drives combine to make the new NEBS-compliant motherboard-based servers extremely powerful, cost effective and flexible. Now, more than ever before, telecom applications can be implemented via simple 1U server solutions. • Military Disk Arrays: • Disk drive advances in capacity and ruggedness now allow the creation of massive (10 TB or more) removable disk drive modules that are extremely rugged. One of the best application for this new technology is for data storage in intelligence gathering operations, where the drives can be quickly removed for secure storage at the end of each mission.
The First GPU/SSD 2U Server The first server to offer the option of either an AMD dual sixcore Opteron-based motherboard or an Intel dual Xeon-based motherboard and eight PCIe x16 Gen 2 expansion slots in a 2U chassis. The system supports 10TeraFLOPS of GPU compute power or 5TB SSD storage or a combination of both. In addition, OSS has packed even more storage capacity into the system with four hot swappable hard disk drives and an internal RAID controller. The server is powered by dual, redundant 1,500 watt power supplies and housed in a 2U high chassis designed and manufactured to meet rigorous environmental demands. • Dual AMD Opteron or Intel Xeon processors • Supports up to 10TFLOPS GPU or 5TB SSD • Dual 1500 watt power supplies • Quad 3-1/2” hot swappable drives
1U and 2U Acceleration Systems Provide GPU and SSD Expansion OSS PCIe expansion platforms are designed specifically for high performance computing and high speed graphics. The expansion platform supports either two double-slot graphical processing units (GPU’s) or four single-slot GPU’s. An internal system monitor surveys system parameters and reports status through an Ethernet port on the rear of the enclosure. The PCI Express interface delivers data transfers up to 80Gb/s to the host system through a host adapter that installs in the host computer’s PCIe x16 expansion slot. A 1-meter standardized PCIe x16 cable is included with the platform. • Expansion connectivity to Gen 2 host systems at 80Gb/s • Includes PCIe x16 Gen 2 host cable adapter and 1 meter cable • 1U supports two double-slot cards or four single-slot cards
One Stop Systems remains committed to technological innovation as a means to providing state-of-the-art solutions for our customers.
• 2U supports four double-slot cards or eight single-slot cards
