Memory... Memories and the Fall of Civilizations
hat is memory? In its most basic form, it is the establishment of synaptic connections in the brain. But as we all know, especially as we get older, that is a temporary and unreliable means of actually preserving information. So over the centuries memory has taken the form of impressions in clay tablets, monumental stelae, hand-calligraphed manuscripts, runes, parchment volumes laboriously copied in monasteries, and ultimately, the printed word. The 20th century saw the arrival of photographs, film, video, phonograph, tape recording, and now a blistering variety of digital technologies. It is, of course, these latter that concern us most today. Without digital technologies there would be utterly no way to accommodate the flood of information that is cascading over the world, and yet sometimes a question arises: Archaeology has been able to unearth and interpret the information left by previous civilizations. I wonder if it will be that easy for future excavators or visiting aliens to uncover and decipher ours. In order to read our technology we need other technology, and how durable is digital memory over long centuries? As durable as stone? We have lost great repositories of information in the past such as the Great Library of Alexandria and through the wholesale destruction of the Mayan manuscripts. These speak to the vulnerability of centrally stored, non-redundant data. Today’s data is nothing if not decentralized and redundant in the form of the Internet. Most of the data, however, is on spinning media in server farms all over the world. The technology that makes it available is a web of wired and wireless communications held together by other data in the form of domain servers. Access to the data is by means of yet another technology known as search engines. As wondrous as all this is, there is still something about it that feels tenuous. At least it feels tenuous over the long term, and by that I mean centuries. The curve of the increase of information will continue to climb necessitating new technologies to contain it. What is the life in hundreds of years of a magnetic disk, of flash memory? If and when our civilization does collapse from war or climate change or an epidemic of gout—whatever—will our learning really be available to future civilizations—ones perhaps worthy of the name?
Some very minor glitches are starting to appear. We have all had, or will one day have, the experience of an older loved one passing away. Part of the experience is going through an attic or basement or closets and finding boxes of old letters, pictures and cherished objects. I remember finding a bundle of letters written by my father from the Pacific during World War II. That killed an entire afternoon. What would have happened if those had been emails? They would not have been accessible over the Internet or by any search engine. And yet such normally personal things are often key to insights into history. Caroline Alexander, author of The Bounty: The True Story of the Mutiny on the Bounty, of course researched the records of the British Admiralty and other official documents, but she also gained access to private letters still kept in homes by the descendants of sailors who had been aboard the Bounty. These gave priceless insight into unraveling the actual story of what happened. Dad also left behind a bunch of documents on 3 ½-inch diskettes. While there was nothing on them that was nearly as interesting as the letters from the Pacific, establishing that fact was a genuine hassle. Nobody had a computer handy with a 3 ½-inch drive. Ten years from now, it will be genuinely a hardship and beyond that might take a forensics lab. Useful data and records need to not only exist in public archives, but also in the attics and old media of ordinary people. With the rapid changes in media and interfaces, much of the access to such information may become increasingly difficult to the point that we may lose valuable insights into our historical and cultural heritage. Just finding things could be harder as well. There is no search engine or indexer for a closet. I’m not sure what the answer is from a technology standpoint. On one hand, vast amounts of data and knowledge have been made available to almost anybody in an instant. Technologies for accessing and organizing that data have advanced as well. And yet, the preservation of all of this does not seem to have been thought out. If this by no means eternal civilization continues, the data will be carried forward on new technology—at least the public data. The private, often more interesting stuff is a different matter.

INDUSTRY
INSIDER NOVEMBER 2009 CP-TA Introduces Self-Testing Program for xTCA Interoperability The Communications Platforms Trade Association (CP-TA) has introduced a self-testing program for the interoperability of xTCA (AdvancedTCA, MicroTCA, AMC) building blocks. Companies can now utilize the interoperability criteria, test procedures and test tools developed by CP-TA and its members to perform self-testing in order to verify xTCA product interoperability. CP-TA empowers the xTCA ecosystem by providing standardized, proven guidance and tools to lower integration costs without the added expense of a formal third-party certification program. In addition to its continued work toward easing xTCA interoperability challenges for traditional telecom central office applications, CP-TA has also expanded its mission to include xTCA communications platforms used in Military, Aerospace and data center applications as well. While originally designed for use in telecom network operating environments, xTCA has gained traction in additional markets due to the advantages of open standards, inherent reliability and power efficiency. Vendors supplying to each of these vertical markets share similar xTCA interoperability objectives. Today’s announcement comes in conjunction with the organization’s recent designation of Polaris Networks’ MicroTCA Tester and AMC Tester as suggested tools for use with CP-TA’s Interoperability Compliance Document (ICD) and Test Procedure Manual (TPM). CP-TA approved Polaris’ ATCA Tester earlier this year as an authorized test tool, and all three tools are harmonized with the ICD and TPM to test for manageability interoperability of xTCA building blocks. Furthermore, CP-TA has negotiated for certain discounts on xTCA test tools from Polaris Networks for member companies depending on the level of membership. Similarly, CP-TA is working with additional tools providers to develop thermal testing tools so that companies can test xTCA products for CP-TA B.x thermal compliance. To correspond with the goal of broadening its focus, CP-TA has restructured its membership levels and now offers a “Participant” level for $2,000. The new level offers members significant technical and marketing benefits at a relatively low cost, and provides an easy entry point for joining and participating in the organization. A list of membership levels and benefits is available on the CP-TA Web site www.cp-ta.org.
RTI DDS Selected for Upgrade of Grand Coulee Dam’s Control System
Real-Time Innovations has announced that the U.S. Army Corps of Engineers has selected RTI Data Distribution Service (DDS) for an upgrade of the Grand Coulee Dam’s control system. RTI’s middleware will integrate components of the dam’s nextgeneration Supervisory Control and Data Acquisition (SCADA) system, enabling more efficient and reliable hydroelectric power generation. The Grand Coulee Dam is the largest hydropower plant in the United States. The plant must carefully control how it supplies power to the grid. Failures that cause power spikes or dropouts are not

acceptable. The project to retrofit the control system is for the U.S. Bureau of Reclamation (BOR) in cooperation with the Bonneville Power Administration (BPA). The U.S. Army Corps of Engineers Hydroelectric Design Center (HDC) is the system integrator; HDC selected RTI Data Distribution Service to implement a highly available, high-performance and scalable control system. The dam network connects a 40,000-point SCADA system controlling 30 generators to the transmission switchyard. In the new architecture, RTI DDS will be used to integrate 50 to 60 Linux-based Programmable Logic Controllers (PLCs) on the central control network with Windows Human-Machine Interface (HMI)
systems and various database and health-monitoring servers. The system will run on standard, ruggedized commercial computing hardware. The architecture will eventually be deployed on a network of 12 dams in the Federal Columbia River Power System. Automated Control Systems (ACSI) is a contractor on the project. ACSI President Dan Perrier noted, “The dam control system processes waveform data, power metrics, temperatures, oil levels, vibration sensors and more. The current system uses many different protocols. DDS, with its flexible configuration and high performance, is easier to work with and is a better way to integrate the systems.” RTI DDS provides messaging for mission-critical distributed ap-
plications. It combines low latency, high throughput and fault tolerance in a scalable architecture for real-time systems. Systems built with RTI middleware are loosely coupled; they communicate easily but under strict Quality of Service (QoS) control. Developers can specify the exact needed timing and reliability for each communication path. Direct peer-to-peer connection ensures fast delivery with no single points of failure. Automated configuration allows hot-swap, non-stop redundancy. Subsystems can start in any order, join or leave, or insert upgrades without impacting existing operation. RTI reliably delivers the right data to the right place at the right time.
ISM and SUMIT-ISM Specs Bring SUMIT Expansion to 90 x 96 mm Stackable Modules
The Small Form Factor Special Interest Group (SFF-SIG) has announced the availability of both revision 1.0 of the Industry Standard Module (ISM) and the SUMIT-ISM specifications for small, rugged, stackable embedded systems. The SUMIT-ISM specification documents the use of SFF-SIG’s flexible Stackable Unified Module Interface Technology (SUMIT) interface on popular 90 x 96 mm stackable modules. The ISM specification provides an explicit form-factoronly definition upon which the SUMIT-ISM specification is built. Since the SUMIT specification itself defines only a board-to-board interface (connectors and pin definition), the ISM specification is necessary to define the form factor while the SUMIT¬-ISM specification defines how SUMIT is implemented on ISM modules. In order to support a wide variety of legacy 90 x 96 mm modules marketed as PC/104 or PCI-104 modules on a SUMIT-
ISM stack, the SUMIT-ISM specification offers a high level of flexibility to maintain compatibility. The SUMIT-ISM specification defines two legacy stack types, using slotted mounting holes on ISM modules to provide symmetry not found with PC/104. This enables SUMIT-ISM modules to be created with legacy support for either the PC/104 ISA bus or the PCI-104 PCI bus by allowing the module to be rotated 180 degrees as necessary to fit the legacy type required while maintaining the SUMIT interface. Legacy bus support can be supplied by the CPU and maintained up the stack, or it can be provided through a bridge module in the stack itself. With SUMIT-ISM, stackable I/O expansion is implemented using the SUMIT standard introduced by SFF-SIG in early 2008. Through the inclusion of one or two 52-pin SUMIT connectors, a SUMIT-ISM CPU can provide PCI Express (up to 6 x1 lanes or 2x1 and 1 x4 lane), USB 2.0, LPC, I2C and/or SPI interfaces to the SUMIT-ISM I/O modules. The SUMIT-ISM CPU designer has the flexibility to provide all or any subset of these interfaces. In anticipation of the release of these specifications, SUMITISM CPUs are already available from member companies ADLINK and VersaLogic. SUMIT-ISM I/O modules are available from member companies VersaLogic and WinSystems.
“Tree Power”—Bio-Energy for Forest Service’s Climate Sensor Network
Voltree Power has announced its first contract with the USDA Forest Service, following a rigorous and successful test in June of its Climate Sensor Network. The Climate Sensor Network complements the USDA Forest Service’s Remote Automated Weather Sta-
tions network. Its durable and inexpensive mesh network of lowpower sensory nodes was designed to operate underneath the forest canopy, and collect and report data on wind speed and direction, air humidity, and temperature. The data, which is transmitted back to fire officials, can be used to assist in the prediction of areas in the forest at higher risk for fires at the time the information is collected. The initial contract is for a total of five network systems, the first to be deployed in Boise, Idaho, and tested through the end of this year. In 2008, Voltree Power received a patent for its bio-energy harvesting technology, which collects the energy that is naturally produced by living trees and other large plants, and uses it to trickle charge and run low-power circuits. The USDA Forest Service is evaluating a wireless mesh network application of the technology, with nodes that consist of low-power transceivers, sensors and Voltree Power’s bio-energy harvesting technology. Data collected by the nodes would be transmitted from one node to another until they reach a central monitoring station. Each station provides a satellite microwave uplink connection that allows the collected information to be shared with government agencies and many others worldwide. The USDA Forest Service and the Bureau of Land Management are not the only major entities to recognize the potential of Voltree’s bio-energy harvesting technology. Texas Instruments has been a contributor to the development of the Climate Sensor Network, providing industry-leading, ultra-low-power embedded processing and power management technology that enables innovative, self-powered applications. In addition, work by a group at the University of Washington with no
ties to Voltree has confirmed the viability of operating low-power circuitry from tree power, a methodology covered broadly by Voltree’s issued patent and pending patent applications.
Giesecke & Devrient and Phison in Joint Venture for Secure Flash Solutions
Giesecke & Devrient (G&D) and Phison are joining forces to develop and market secure flash products. Their joint venture— Giesecke & Devrient Secure Flash Solutions GmbH—will be headquartered in Munich, Germany, and will have a second office in Taipei, Taiwan. It will develop and market hardware-based security solutions for mobile end devices, for example in the form of microSD cards and USB tokens. G&D will hold a 70 percent majority stake in the joint venture. Mobile end devices for communications and multimedia applications such as notebooks, cell phones, mobile TV equipment and games consoles have become an integral part of everyday life. These applications make it necessary to protect the digital identity of the user. At the same time, mobile transactions made using the equipment and data stored on it also need to be protected against unauthorized access. Giesecke & Devrient Secure Flash Solutions will offer security solutions that cover these market demands and are designed for special applications such as the encryption of emails or cell phone conversations, or mobile pay-TV. The Mobile Security Card already developed by G&D using flash controller technology from Phison is a good example of such solutions. In the future, the Mobile Security Card will be further developed by Giesecke & Devrient Secure Flash Solutions and
marketed by the joint venture. New generations of the Mobile Security Card, such as for contactless applications, and other secure flash products are already under development. Potential clients include manufacturers and other providers who are interested in integrating secure applications into mobile end devices. These may be PC and mobile equipment manufacturers, system integrators, retailers and/ or providers of access systems for mobile TV applications.

graphical processors have incorporated an architecture called Compute Unified Device Architecture (CUDA) on their graphic cards. CUDA processors were designed to be highly parallel graphical engines programmable in C. Millions of units have already been sold for exactly that reason, but they turn out to be capable of much more. While the latest generation of generalpurpose, multicore processors is spurring the development of virtualization techniques and hypervisors to bring out their full potential, the CUDA architecture is programmable in C and has a runtime component that can spread sections of parallel algorithms over its complement of available cores. The performance gains can be impressive. GE Fanuc, which has entered a partnership with Nvidia to develop new hardware products using the CUDA architecture, is very focused on rugged devices for aerospace and military applications where size, weight and performance (SWaP) are critical. GE Fanuc’s estimates are that it can keep the same level of performance for a given system and implement it in about 10 percent of its current size and weight. This would translate to 1000 percent performance in the same size and weight. In an autonomous vehicle, the speed at which the system can process algorithms determines the speed at which the vehicle can move. Increases on the order of 15x have already been reported. This is now attracting the development of applications in fields as diverse as medical research and life sciences, fluid dynamics, signal processing and video processing, among others. For example in computer fluid dynamics (CFD) applications, the program algorithms model the physics and then for each iteration of the model, render a display image. Thus, high-speed modeling and graphics generation are taking place on the same set of processor cores. In video processing, the same GPU that is known for generating graphics is also able to take in that
editor’s report
video data and process it for things like face recognition and other image processing tasks. The CUDA architecture consists of a number of parallel general computing cores. There are different versions of CUDA processors, and performance varies depending on the number of cores in a particular model. The software model, however, is consistent across all versions of CUDA. CUDA still acts in the role of a coprocessor with a general-purpose CPU (at this point an x86) running the main program. The developer writing in C with extensions for CUDA decides which parts of the code are appropriate to run on the GPU and identifies them. When the main processor encounters a section of CUDA code, it diverts it to the GPU, which returns the results as appropriate to memory (Figure 1). OpenCL, a parallel compute model for parallel processing across heterogeneous devices, enables compliant drivers to be used to run the parallel code. As mentioned, GE Fanuc has entered a partnership with Nvidia, and as a major prime contractor in the military/aerospace industry, has evaluated the CUDA architecture in a radar system and found that performance improvement of 15x is achievable with minimal reprogramming effort. Other prime contractors are expressing substantial interest in the technology. In addition to having potential applications in radar, signals intelligence, and video surveillance and interpretation, GE Fanuc sees GPUs based on the CUDA architecture to represent big potential in other application areas including target tracking, image stabilization, SAR (synthetic aperture radar) simulation, pattern recognition, video encoding/decoding, graphics rendering, object recognition, cryptography, sensor processing and software defined radio. Traditional graphics applications will also benefit greatly from high-performance Nvidia GPUs. The first board will be 3U VPXbased and will benefit from a broad-
ranging supporting infrastructure of other GE Fanuc 3U VPX solutions and services, allowing customers to specify tailored multi-board solutions. Alternatively, a CUDA-enabled 3U VPX rugged graphics subsystem will also be available. A family of 6U VPX products will feature combinations of Intel dual core processors and Nvidia CUDA-enabled GPUs, allowing designers to create powerful multi-board solutions for demanding applications. This family, as well as the new 3U VPX platform, will additionally support OpenCL. Beyond that, the potential for other compute-intensive applications support exists for any number of vendors adapting CUDA or similar parallel architectures. Main Memory
Nvidia’s Web site offers a software development kit for CUDA including a set of drivers, a set of CUDA development tools and a library of code samples. The development environment is available for Windows XP, Vista and 7 as well as for Linux and MacOS from its OpenCL downloads page. These can be used for developing a wide range of general-purpose computing applications on the CUDA architecture.

specialization to make itself attractive to more than its initial target application. A number of semiconductor companies have contracted to develop a processor with a select combination of peripherals on-chip for a given customer’s needs with the proviso that they would then carry that design in their product portfolio and make it available to other customers. The result—especially in the 8-bit microcontroller arena but also with 32bit devices—is a vast number of devices all built around the same core. Just think of the number of 8051-based devices that are out there on the market. And there are many more built around other cores. Finding the right one with the desired mix of peripherals requires Web searching and poring over catalogs. Then, of course, if you want to scale up and move your work to a 16- or 32-bit platform, the fun begins again. Recently, Cypress Semiconductor has added a scalable 8- to 32-bit path with additions to its existing 8-bit line of programmable systems-on-chip: the PSoC device, in the form of PSoC3, based on an 8051 core, and the PSoC5, which is built around the ARM Cortex-M3 and is capable of running ARM’s Thumb 2 16bit code or 32-bit code. The two devices

represent a scalable, programmable platform for embedded development that incorporates a wide selection of digital and analog peripherals. The PSoC3 and PSoC5 architectures are differentiated mainly by the different processor cores but are essentially similar (Figure 2). The CPU subsystems consist of one of the two CPUs and several hard-wired blocks for CAN 2.0, USB 2.0 and I 2C interfaces as well as a DMA controller, EEPROM, flash memory and debug interfaces among others. The chip has an interface to external memory as well. The blocks on the CPU subsystem have connection paths to the programmable routing and interconnect block on the programmable routing and interconnect layer where they can be routed to external GPIO ports or peripheral blocks on the configurable analog and digital layer. The analog and digital layer consists of two sections. The digital subsystem contains an array of universal digital blocks (UDBs), which consist mainly of programmable logic that can be defined as digital peripherals such as UARTs, pulse width modulators, LCD drivers and controllers, timers, multiplexers and many more by means of the PSoC Creator de-
velopment tool. The UDBs can also be set up for custom logic such as “glue” logic or selected other functions. By the same token, the analog subsystem contains programmable elements for DACs and ADCs, op-amps, comparators and customizable analog blocks that can be defined from a library of pre-built, characterized components, again using the PSoC Creator tool. In addition, it contains a configurable digital filter block capable of two separate filter channels and up to four cascaded filters per channel. Analog channels are capable of up to 20-bit resolution with ± 0.1V reference voltage. Both PSoCs have a wide operating voltage of 0.5Va to 5.5V and can be set to operate with external devices at different voltage levels in up to four different voltage domains. In addition, there is a power management section with three power modes: active, sleep and hibernate. The latter consumes only 300nA in hibernate mode. Configuration of the PSoC 3 and PSoC5 is done with a graphical tool called the PSoC Creator, which contains a library of pre-defined, yet custom-configurable peripherals. To configure the chip, the developer simply drags a peripheral from the list onto the screen (Figure 3) and connects wires to other peripherals, the CPU, I/O and memory blocks or to GPIO ports and then to external pins on the device. Peripherals such as digital filters can be further configured by setting their parameters to the appropriate values. Peripherals can be given appropriate names, which then become part of the API and callable from application software. The PSoC devices additionally are supplied with a set of third-party compilers and IDEs for developing application code in C as well as on-chip JTAG debug and trace tools. Code, for example, that was developed for the 8-bit PSoC3 can be readily recompiled for use as 16-bit or 32-bit ARM applications. In addition, a peripheral configuration developed for the 8-bit device can readily be ported to the ARM-based version allowing upscaling of a given solution and the ability to enhance it on the new platform without redoing the earlier development.

ARM Joins the FPGA
The ARM Cortex architecture is also moving into the world of the FPGA for a new generation of programmable logic devices with embedded hard-wired processor cores. Xilinx, whose successful Virtex line of FPGAs that incorporate the PowerPC architecture has gone through a series of versions and enhancements is now adopting ARM Cortex processor IP, using performance-optimized ARM cell libraries and embedded memories for their future programmable platforms. In addition, ARM and Xilinx are working to define the next-generation ARM AMBA interconnect technology that is enhanced and optimized for FPGA architectures. The agreement indicates Xilinx’s intent to adopt ARM technology to provide flexible computing platforms where IP and software development can be shared and re-used on a broad scale. To help create a more optimal ecosystem serving both Xilinx FPGA and ARM IP technologies, the two companies are already working with a number of IP providers and EDA vendors including Cadence Design Systems Inc., CAST, Inc., Denali Software, Inc., Mentor Graphics Corp., Northwest Logic, OMIINO Ltd., Sarance Technologies Inc., Synopsys, Inc. and Xylon, to support an advanced version of the AMBA specification, the de facto standard for on-chip fabric communication, which is closely aligned to ARM processors. Not only will this new interconnect simplify and extend the capabilities of next-generation programmable platforms using 32-bit processor IP, but the definition of the standard is aligned with the “Socketable IP” aspect of the Xilinx Targeted Design Platform strategy. Because IP reuse is an essential component in reducing system development costs and timescales, this plug-andplay approach means that IP developed by Xilinx and its ecosystem can be easily used without requiring the user to make a huge investment in vendor support. The AMBA protocol for on-chip fabric communication details a strategy for the interconnection and management of functional blocks that make up a system-on-chip. (The new collaboration

with Xilinx optimizes this for FPGA implementations and introduces a new use model of being used with or without processors as well.) The move to ARM aligns with the Xilinx Targeted Design Platform Strategy announced earlier this year, when the company mapped out plans to roll out development platforms based on FPGA technology, boards and standardized IP. A key component of the Targeted Design Platforms is ecosystem participation enabling mutual customers to easily scale their product designs around a stable architecture. Neither company has been specific about concrete product plans at this point, such as whether the agreement will entail both hard and soft versions of the ARM architecture or what types of devices will be rolled out. The Xilinx line of Virtex FPGAs consists of several families optimized, for example, for high-performance logic, DSP applications, high-speed serial connectivity and the like. At this point there have been no products announced, but the penetration of the ARM architecture into ever more deeply embedded applications is certainly apparent and serves as yet another example of the ongoing
effort in the industry to find the “sweet spots” among performance, flexibility, integration and speeding time-to-market while bringing down costs. It is a neverending quest. NVIDIA Santa Clara, CA.

New Direction for Mezzanines
New Generation of M-Modules and PMCs Saves Development Time and Money FPGA technology built into a flexible submodule that can fit onto popular mezzanine standards can speed time-to-solution for a variety of specialized I/O demands. by Barbara Schmitz, MEN Mikro Elektronik

ndustrial embedded applications with small or medium volumes need tailor-made control solutions that can be implemented as much as possible on the basis of standard components. The development of any mezzanine concept is focused on flexibility to achieve low design costs and a short time-to-market. This is true for the various system-onmodule (SoM) families, which accommodate the CPU functionality on a plug-on module, as well as for mezzanine standards like PMC or M-Module, which typically place I/O functions on the plug-on module. Despite mezzanine technologies, the differences between I/O requirements may be huge, so it is not always possible to meet demands through available standards. Cost-effectively mitigating development costs and production time has historically been a challenge for embedded designers. One approach to optimizing I/O flexibility is the Universal Submodule (USM) that uses FPGA technology, which has become inexpensive for even simple I/O demands. The functionality of the mezzanine module is defined solely through

USM was designed in such a way that it can be used for both PMC modules
and M-Modules, the two most popular mezzanine standards.

alone platforms. A 6U board can accommodate up to four M-Modules or three PMCs, while a 3U board can carry one PMC or up to two M-Modules.
Looking Forward with FPGA Technology
The Universal Submodule concept gives life to a new generation of M-Modules and PMCs that implement the desired functionality entirely in the shape of an IP core or a number of cores inside the FPGA. The FPGA itself is located on the “basic” PMC or “basic” M-Module and is a Cyclone II component from Altera in different versions starting at a size of 18,752 logic elements (which corresponds to about 225,000 gates). The hardware configuration of the FPGA is loaded during the boot phase from an external, 2 Mbyte NOR Flash using a CPLD, and is serially transmitted to the FPGA (Figure 1). The flash memory contains the source
16
NOVEMBER 2009 RTC MAGAZINE
code for a minimum configuration of the FPGA over a PCI bus connection. When the Cyclone II is programmed with the basic configuration, the hardware configuration itself can be loaded into the second area of flash memory via the PCI bus. The Nios soft processor, also implemented in the FPGA, can provide local intelligence where needed. Accordingly, up to 32 Mbytes of DDR2 SDRAM can be assembled on the basic “main module.” The cores inside the FPGA may have totally different functions from computer I/O, such as graphics, Ethernet and UARTs, to mobile or industrial communication with fieldbus connection, including CAN bus, Profibus, Industrial Ethernet, IBIS and MVB, up to typical industrial functions such as digital/analog process I/O, motor control and SSI. The configuration of a USM-based M-Module or PMC can be changed at any time through the implementation of different IP cores. Except for their FPGA contents, the main
M-Modules or main PMCs have a fixed hardware setup. On the front, the userdefined I/O signals from the FPGA are led to a 50-pin SCSI 2 connector, chosen because it fits on the mezzanine card with the smallest width, the M-Module. The line drivers related to the function of the IP cores are decoupled from the main module and are implemented on the USM. The USM simply plugs into the corresponding main PMC or main M-Module (Figures 2a and 2b). The mechanical setup of the USM provides maximum space for electronic and mechanical components. This not only includes the available surface of the USM but also the component heights. Maximum component heights are defined by the different mezzanine standards, and therefore vary. In order to reasonably place a USM within the very small dimensions of a PMC module, a special pass-through connection is used. As for the maximum surface, different mezzanine card formats and the additional space needed for the temperature interfaces on a conduction-cooled PMC module were taken into account. The electrical connection between the USM and its main M-Module or main PMC consists of two 64-pin plug and receptacle connectors, respectively. J1/P1 makes the connection that transfers the communication signals generated on the USM back to the main module. On this card, J1 is directly connected to the 50-pin front connector. The signal lines are routed in such a way that there is a sufficient isolation distance to develop a USM with four electrically isolated channels, for instance. The second connector, J2/P2, is the electrical connection between the main module’s FPGA and the USM. Among others, 12 ground pins are evenly distributed over the complete connector. The USM is supplied with 3.3V and 5V using two pins each. Since I/O functions are realized in the FPGA, the lifetime of a PMC module or M Module no longer depends on the availability of commercially available components. Even after 10 years and more, older IP cores can be updated and brought into a newer and maybe larger FPGA. Both MModule and PMC main modules and the USM plug-in modules are designed for an

operating temperature of -40° to +85°C. To meet demands for increased shock and vibration resistance, the boards are equipped with soldered components and sturdy connectors. The first USM-based standard PMCs brought to market include a four-channel CAN bus interface, a four-channel RS422/485 interface, dual Fast Ethernet and a reflective memory PMC module. To implement these functions, four different USM plug-in modules could also be used to bring the same functionality to MModule mezzanines.
Broad Range of Applications
Due to the universality of the USM concept, there are no restrictions regarding the target markets and the type of application. A number of implementations are possible from machine control in industrial settings to test and simulation systems in automobiles or in telecommunication up to monitoring and control in mobile and safety-critical applications. However, the following are a few realworld examples of how the USM concept is being implemented across various applications (Figure 3). In one of the first applications to use M-Modules as a hardware platform, the USM-based M-Module was an addition to existing CompactPCI systems and also to industrial PCs where a number of other M-Modules were already being used. Since the desired functionality was very specialized but had to be combined with different functions on a single module, USM provided the fastest and least expensive solution. The FPGA contains a CAN bus controller already available as a standard core as well as a K-/L-Line interface. Apart from the CAN bus and K-/L-Line line drivers, the USM includes a FlexRay controller and digital I/O in hardware. The USM-based M-Module is a part of computers used to test anti-lock braking system (ABS) control devices inside vehicles and is used both in the lab and in series production as well as for reprogramming during maintenance. In an application for testing systems for the aircraft industry, PMC main modules are the platform of choice. Here, PowerPC-based VMEbus computers are used
Figure 3 Cost-saving USM-based modules are employed in a number of applications from light duty industrial to heavy, missioncritical.
in simulation, validation, test and maintenance. Interfaces such as ARINC429/629, MIL-STD-1553 and AFDX, which may vary from one application to another, are integrated using PMC modules. In order to guarantee that current projects are future-safe, controller components for airplane fieldbuses, such as ARINC429, are implemented only as IP cores in the FPGA, with the line drivers realized on a USM plug-in module. The performance of the FPGAs is sufficient for up to 32 channels in the system with a data rate of 100 Kbits/s each.
Comprehensive Development Package
A considerable range of functions implemented as IP cores are now available on the market, for example from opencores.org. For its own boards, MEN Micro uses a continuously growing number of IP cores designed on its own on the basis of Wishbone, which are also used to complete customized solutions. With the growing acceptance of FPGA-based approaches, more users can develop and integrate their own cores. To do this—as is the case with the USM concept—users should get support from the hardware manufacturer. For this reason, there is a comprehensive development package for M-Modules and PMC modules based on USM that enables the user to easily and quickly turn very specific I/O requirements or individual functional combinations not available as a standard configuration into series products.
The USM development package includes a main M Module (M199 equipped with an FPGA, 32 Mbyte DRAM and 8 Mbyte flash) or a main PMC module (P599 equipped with an FPGA, 32 Mbyte DRAM and 2 Mbyte flash). In addition, the package includes a bare USM plug-in module, a test board where I/O signals from the FPGA are led, a SCSI cable for connection between the main module and test board as well as an FPGA package. A debug interface for the Nios soft core is included on the main modules. The FPGA package comprises the Nios processor, memory control, connection to the PMC or M-Module and the Avalon/Wishbone bridges. For development of IP cores on the standard Wishbone bus, the Wishbone BusMaker tool from MEN Micro is included. In order to use the Nios core and to develop IP cores on the Avalon bus, users also need Altera’s Quartus II design environment including the SOPC builder.
USM as an Open Specification
To give access to the new concept to other vendors of PMCs and M-Modules, MEN Micro has published the entire USM specification. It documents the mechanical and electrical characteristics as well as environmental requirements for the different main modules and the corresponding USM plug-on cards. The driving requirements for the development of this concept included a simple design structure, low production and design costs, ruggedness for harsh and/or mobile industrial environments and a maximum size of the USM module. The same USM was designed to be as large as possible and still be pluggable onto M-Modules, PMC modules or XMCs and conduction-cooled PMC modules. It is even possible to use two USM cards on one Eurocard. For the user, new designs of future USM-based PMCs and M-Modules primarily involve the FPGA content, and therefore save significant development time and costs. MEN Mikro Elektronik Ambler, PA.

uch has been written about the virtues of MicroTCA platforms and AdvancedMC (AMC) modules. Both of these technologies have been maturing and there are now numerous options and flexibility to configure a wide range of applications with products that exist today. So let’s explore in detail some application configurations. In the examples below, we will look at all the components that are necessary to configure an end-user application. On the hardware side, this includes the MicroTCA chassis (which includes the backplane, power and cooling), the fabric switching such as Ethernet, PCI Express and SATA, IPMI Platform Management, and the AMC payload boards. The payload boards can range from processors, to storage/video, to I/O access cards. On the software side, this includes the Operating System, the Development Environment and, of course, the application software. MicroTCA and AMC are COTS-based standards. As such, components from one vendor are specified to be compatible with other vendors components. This is highly beneficial, as it offers embedded designers with the freedom to choose components from as many vendors as necessary to configure their specific application. In fact, there are industry events occurring annually whereby multiple COTS vendors meet to verify compatibility between AMC modules and MicroTCA platforms, enabling cross-company product integration. While it is fundamentally true that the chassis, mezzanine and MCH components from different vendors are compatible with each other, often a significant amount of time and resources are required in order to complete the integration process to ensure final product compatibility and configuration. This gets more complicated when you need to incorporate an operating system, development environment, APIs, drivers, and other software stacks besides the application. So while on the surface, this seemingly wide range of options exists, there are several important nuances to AMCs and MicroTCA,

whereby a single vendor who offers a full suite of hardware pre-integrated with software components can maximize the value of a configured system, increase functionality and performance, and guarantee full compatibility directly from the onset. Listed below are several aspects of a fully integrated platform, called an Application-Ready System.
One is configuration. A single vendor who can integrate their components together—and right out of the box, can ensure that these components are configured properly, that the appropriate onboard switches are set, and test to make sure the hardware and software components are compatible and functioning properly.

Figure 3 A Wireless Gateway System.
Another important aspect is unified tech support. If any technical issue arises, a single tech support group can more quickly debug and isolate the issue through all the components that are integrated together. Dealing with disparate tech support groups can lead to delays, as they may not be able to replicate the same configuration, or not clearly understand a third-party board’s specific issues. Or worse, blame another vendor for the problem. Product uniformity may at first seem superficial, but this can range from the physical appearance, such as the labeling on the faceplates of the AMCs and platform, to functionality on AMC modules, software, or even firmware such as the sensor thresholds and FRU information that are programmed into the MMC management controller. Management software is an essential element, and several MicroTCA system vendors provide Web-based management portals (Figure 1) that are typically programmed to enable off-site development, systems and module management, as well as monitoring of system-wide status and operations. Finally, compatibility of the operating system suite with hardware must be assured throughout. In selecting a Linux software suite, make sure to consider a solution that provides all the necessary components such as Operating System, IDE, kernel builder, image builder, compliers, linkers, debuggers, cross platform develop-
ment, hardware drivers, network services, platform management and Web-based system management. In addition, a suite that is developed to be specifically compatible with a suite of hardware not only ensures compatibility, but also provides synergistic features for an overall solution. In all the application examples below, a 1U MicroTCA platform that houses six AMC slots is a perfect balance between having enough slots to house all the AMCs with room for scalability, but not more slots than will be cost-effective. What is also important to consider are the cost trade-offs between reaching the right level of high availability with going all the way to a fully redundant platform. Components that are most apt to fail, such as power supplies, fans, or hard drives, need to be redundant and easily serviceable. Electronic components on backplanes and/or motherboards have a high MTBF and offer a high level of reliability.
Example: Wireless Base Station
Data overload is already a reality with mobile operators, as consumers are rapidly adopting mobile smartphone devices and using them to download news and information from the Internet. One recent industry study involving millions of mobile device users indicated that these same users doubled their network usage in one year. 4G technologies, such as WiMax and LTE applications, are de-

signed to handle heavy usage of mobile data. MicroTCA and AMC modules are a good fit with these types of applications, as they provide a carrier-grade platform with high-speed fabrics, high reliability, remote platform management and hotswap functionality in a cost-effective form factor. Even defense departments are keyed in on wireless solutions for Network Centric Warfare communications. Wireless applications require real-time signal processing with high-bandwidth communications on and off the boards. A 1U platform supports the four major functional blocks: 1) RF, 2) Baseband, 3) Control and 4) Transport. The AMC ecosystem offers AMC modules that support both the RF and Baseband functions on a single card or separate cards with a direct connection to the Remote Radio Head (RRH) for three-sector operation utilizing both a Xilinx FPGA and multiple TI DSP cores. The Control function is handled by a multicore processor AMC. And the transport for the backhaul is accommodated on Ethernet uplinks from the MicroTCA platform, or for legacy deployments, it can utilize a T1/E1 AMC module (Figure 2). The 1U MicroTCA platform is an ideal form factor with six AMC slots, as it can house all four functional blocks in a single shelf with room to scale to a second RF/Baseband AMC module if needed. Larger MicroTCA platforms that house 8 to 12 AMC slots are too large and are not cost-effective. For frequency and time synchronization of all the AMCs, the MicroTCA’s clock distribution can deliver a phase-synchronized Stratum 3 signal (e.g. 10 MHz or 30.72 MHz) to all the AMCs derived from an external Stratum 2 GPS Receiver outputting a 1PPS reference signal. In addition, if the GPS reference clock fails or is absent, a crystal oscillator can provide a holdover signal for a limited time until the GPS reference clock is back on line.
and aggregates traffic from base stations, manages the hand-off between the base stations, and provides quality of service. Here too, a carrier-grade architecture ensures hot-swap scalability, high availability and remote platform management. The two primary functional blocks for this
application are packet processing and a control CPU. A high-performance, dualcore processor AMC can handle both functions, and housed in the 1U shelf, can scale up to six processor AMCs. The typical backhaul network is Ethernet to the Connectivity Service Network (CSN), and

the quad 1GbE uplinks on the MicroTCA platform provide ample bandwidth (Figure 3). Media Gateways such as the ones that convert media streams from a Public Switched Telephone Network (PSTN) to an IP-based Network can also take advantage of the MicroTCA architecture. T1/ E1 Communication Controller AMCs can receive multiple lines and perform highperformance and high-capacity processing via a PowerQUICC controller. These AMCs have onboard FPGA with the ability to transmit TDM traffic as I-TDM packets over the Ethernet fabric. In this example, the Media Gateway can scale up with more T1/E1 AMCs as subscriber traffic grows.

These AMCs can be installed in a platform and undergo a Preboot eXecution Environment (PXE) to boot via the integrated Ethernet fabric in the MicroTCA platform. One of the processors in the system can act as a DHCP server to assign an IP address and send the client AMC a list of Boot Servers. This same AMC can act as the TFTP server to provision the new client AMC module with its operating system, application software and any data files. Performance Technologies Rochester, NY.

High Bandwidth and Small Form Factor MicroTCA for Flexible Embedded Design Modular AdvancedMC modules are instrumental to the success of MicroTCA in multiple markets including telecom, networking, medical and other key embedded markets.
by Sven Freudenfeld and David Pursley, Kontron
Embedded systems must meet the growing demand for ruggedness, flexibility, mobility and high-end processing, and these attributes should be designed into standards-based solutions that can be developed and implemented quickly and within budget. Beyond applicationspecific requirements, many embedded system designs may also require features that address low-power, size and scalability challenges. MicroTCA, comprised of modular COTS components such as Advanced Mezzanine Cards (AdvancedMCs), offers some significant design advantages to solve these challenges. AdvancedMCs are the building blocks that make MicroTCA an ideal platform for a broad range of high-availability, highbandwidth embedded designs. Telecom and medical are two market examples that have a diverse set of application requirements, with each demanding a certain level of design flexibility. MicroTCA possesses the practical and cost-effective versatility to meet these demands. Initially designed as a hot-swappable component within AdvancedTCA (ATCA)

integrated in tandem with an ATCA carrier board or within AdvancedMC slots in a CPU or switch blade, AdvancedMCs allow for hot-swap and redundant system management within an ATCA system, or provide additional processing functions on any single ATCA node or switch blade. Another common use for AdvancedMCs is in redundant and non-redundant MicroTCA platforms. Here the form factor can vary between single or double-wide AdvancedMCs and MicroTCA platforms, and provides full-scale PCI Express, GbE, 10GbE or Serial Rapid I/O infrastructure to the system being implemented. A growing number of applications are also using AdvancedMCs with low-cost backplanes and a reduced-functionality infrastructure. This retains the standard AdvancedMC implementation but reduces implementation costs, allowing OEMs to only pay for what they really need. AdvancedMCs have evolved from single or double-wide modules, and based on the PICMG specification, MicroTCA can scale from four non-redundant to up to 12 AdvancedMC modules with redundancy in a MicroTCA backplane. This delivers extensive flexibility in a smaller footprint—a critical feature for MicroTCA-based designs in demanding applications such as telecom or medical imaging. Low-cost AdvancedMC system implementations (designed with direct interconnectivity between two to four AdvancedMC modules via the backplane) also deliver design flexibility in cost and functionality.
AdvancedMC Evolution
Different usage models for AdvancedMC modules have further broadened their use and economies of scale for embedded systems. For example, TEMs can free up valuable ATCA slots by combining general-purpose processing with packet processing functions through the use of AdvancedMC slots with PCI Express, GbE and even 10GbE on a single ATCA blade. This scalability and flexibility have become essential in helping manufacturers manage system upgrades while simultaneously protecting their initial ATCA platform investments. Since AdvancedMCs could be used for a wider range of system-level func-
Figure 2 The Kontron OM6120 brings significant cost improvements compared to conventional MicroTCA platforms. Cost optimization includes Power Management and Fan Control on the backplane, and pluggable Power Supply Units instead of MicroTCA Power Modules. By accommodating a high number of multicore AdvancedMC modules and allowing a tight coupling of processors over high-speed communication links (over the backplane), the system is also well suited for image processing applications in single-channel or dual-channel architectures.
tions, it became apparent that their use could extend well beyond ATCA-based telecommunication applications and into other high-performance computing environments such as medical, industrial and even transportation applications. AdvancedMCs plug directly into the MicroTCA backplane—fundamentally turning the mezzanine itself into a blade, which enables designers to take full advantage of a flexible platform to readily create a small yet highly powerful and scalable system. Consequently, AdvancedMCs can be used as a main controller, data server, traffic processor, image or signal processing engine, security appliance, or network processor—giving designers a cost-effective solution to accelerate to market a finished system that can feature multiple applications on the same platform.
New Telecom Application Enablers
Intelligent networks are being deployed in enterprise, datacenter, broadband and access networks—a new genera-
tion of systems that must effectively handle highly distributed, service-related or legacy architecture applications. As a result, AdvancedMC modules have become an attractive design alternative, meeting needs for deep packet inspection processing (vital to monitor and modify network activities), TCP/IP packet processing and load balancing, content aware applications, security processing, compression/ de-compression and other new and evolving communications services. By providing information about typical activities such as traffic profiles, users, sources or destination, carriers and wireless providers can introduce new tiered services, as well as quality of service (QoS) and enhanced network efficiencies that enable smoother operations and new revenue opportunities. Multicore AdvancedMCs are integral to handling this range of packet and security processing functions including forwarding, load balancing, traffic management and IPsec in both ATCA- or MicroTCA-based environments.

MCs were typically released as Gigabit Ethernet modules, but now more multicore packet processor modules support 10GbE for higher bandwidth applications. This has spurred new growth opportunities for MicroTCA platforms to be designed for media servers, signaling gateways, CMTS-cores, radio network controllers, and more recently, new LTE base station solutions that deliver nextgeneration broadband wireless technology for wide area networks. Sheer cost, power and size efficiencies make MicroTCA ideal to mass deploy, for example, radio access eNodeB systems into the field. The platform approach can include configurations of I/O, general-purpose processor and DSP (Digital Signal Processor) AMC modules (Figure 1).

a system design depends entirely on the features and functions required for the system. Designers have the choice to select an AdvancedMC based on processing performance, communications bandwidth, storage or specific I/O options. For example, processor AdvancedMCs are employed to host microprocessors and network processors. Storage AdvancedMCs are used to host flash memory cards or perhaps a solid-state drive if the design requires critical data storage and support for extended temperature ranges. Since AdvancedMC modules offer a flexible combination of size, performance options and features, designers can create MicroTCA systems with as few as one or two AdvancedMC modules, or as many as the 12 allowed by the MicroTCA specification.

xTCA Expands its Reach with a Thriving Ecosystem
Take RF Measurements Up to 10X Faster
Originally developed to fulfill telecom and carrier-grade requirements for system-level projects designed by telecom equipment manufacturers, the Advanced Telecommunication Computing Architecture (ATCA) standard has experienced an ongoing fine-tuning process. Gaps in the standard have led special interest groups such as the SCOPE Alliance to define a common profile for standard hardware, software components and systems. Since hardware components were standards-based, a seamless integration into a multi-vendor environment was not guaranteed, thus necessitating a common methodology for hardware component testing and verification, which was taken on by the Communication Platform Trade Association (CP-TA). Today, xTCA (ATCA and MicroTCA) is an expanding ecosystem—comprised of component providers, blade vendors, CG OS vendors and system integrators—and includes software vendors offering platform management and middleware solutions. TEMs and NEPs have the freedom to select the best performing general-purpose components and platforms, preventing the “lock-in” approach with second sourcing. Due to the evolution of Gigabit Ethernet technology and the future availability of new switch silicon, recent and ongoing revisions to the PICMG specification are opening the door to other telecom networking applications in core networks that require 40GbE. Future 40GbE-designed ATCA platforms could be used for optical line terminals (OLT) or point-to-multipoint GPON network infrastructures, ideal for the delivery of video services, quality voice and high-speed Internet access. GPON allows one single-feeding fiber from the provider’s central location to deliver data via passive splitters to multiple homes and small businesses.
of AdvancedMC module. For example, a 1U six-slot design could feature a mixed and redundant configuration of processor, storage and packet processor modules to be used for central office SIP Server, SSL offload, content-aware processing and QoS over Ethernet applications. When looking at 12-slot MicroTCA platforms, the resulting design possibilities can make it popular for any number of compute-intensive applications such as medical imaging and screening, and diagnostics and therapy. As a configuration of such a high number of multicore AdvancedMC processor modules that are tightly coupled over high-speed communication links (i.e., over the backplane), this cube form factor is well suited for a range of access and edge network elements for voice, data and video networks. Two of these MicroTCA cubes could even be mounted together in a 19” frame, thus providing space for 24 AdvancedMCs in a 5U 19-inch form factor, achieving an unparalleled density of computing in terms of AdvancedMC space per total chassis volume (Figure 2).

MicroTCA and AMCs in Medical Applications
Many medical applications require high bandwidth and overall processing power, and are an ideal environment for the power and flexibility of a MicroTCAbased platform. Image processing—with emphasis on the processing—is growing as a valuable medical diagnostic tool in the analysis of images and related patient information. Pattern recognition, rendering of organs, and volumetric analysis of a range of image types not only demand heavy processing power themselves, but are frequently tied back to specific patient information in medical databases. Familiar medical procedures such as X-rays have been using digital technologies for some time now—and the processing demands are only increasing. CAT Scans, for example, provide three-dimensional images based on X-rays, ultrasound or nuclear medicine functions such as Positron Emission Tomography (PET) or Magnetic Resonance Imaging (MRI). Coming soon are live images, delivered and used in real-time therapy or diagnostic applications. Consider mass screening

for skin cancer by using spectroscopy in combination with image processing. Advancements in multicore processing, represented by the latest Intel processors and chipsets, have in turn led to the development of new imaging applications that might not have been previously possible due to limited platform bandwidth. Today’s image processing requires many cores, frequently on multiple blades, either tightly coupled over high-speed buses like Serial Rapid I/O or loosely coupled over network protocols such as 10GbE or GbE. Image rendering further demands high-performance graphics boards, which interconnect over high-speed PCI Express lanes. Designers have plenty of options, and high-level imaging can be achieved by stacks of servers or industry standard server blades. However, compared to isolated servers, systems based on server blades include the benefit of higher computing density and the tight coupling of processors over the backplane. In MicroTCA platforms that incorporate multicore AdvancedMCs, the Ethernet network infrastructure is built right into the system. With the ability to utilize up to 12 AdvancedMCs, medical systems can also support effective system management, power management, Ethernet switching and other transport systems, in addition to the processing performance required for compute-intensive imaging applications (Figure 3).
Modular, Powerful and Effective
Ultimately, AdvancedMCs provide diverse applications across a range of communications, networking and medical implementations. Integrated with a MicroTCA 2U platform, AdvancedMC modules can be configured, along with other processor and storage AdvancedMC modules, for powerful integrated security services. When that MicroTCA system builds to 3U or perhaps 4U—and every blade has incorporated a multicore processor—the resulting systems could be operating today with as many as 24 cores. Even with that extremely high level of processing power, such a system would still maintain a very small footprint, an achievement that many designers consider MicroTCA’s most powerful benefit.

Increasing Reliability through Automated Enforcement of Design Rules Advanced static-analysis tools are good at finding serious programming errors.

n the ongoing effort to improve software reliability, advanced static-analysis tools have proven to be effective at finding serious programming errors. These tools use sophisticated symbolic execution techniques to detect bugs such as buffer overruns, null pointer dereferences, race conditions and many others. They excel at finding generic flaws—places where the fundamental rules of the language are violated, such as division by zero errors. They are also good at locating defects that arise because a common library is being used incorrectly, such as a memory or other resource leak. These tools can also be extended to find domain-specific defects. There are many benefits to customizing these tools—improving reliability by finding defects unique to the code base is the main advantage, but it can also reduce the cost of manual code inspections, and help reduce compliance costs by checking adherence to coding standards. Almost all projects have rules about how code should be written, even if they are not explicitly stated. These rules may cover superficial aspects of the code, such as layout, identifier naming and syntactic

restrictions (e.g., no expressions nested more than four levels deep). They may also address semantic properties of the code such as the order in which it is legal to perform certain operations, or how to handle the detection and logging of run-time errors.

the advanced static-analysis tools can effectively find violations of the complex semantics-oriented rules.

configuring the tool to recognize the functions that allocate the resource and those that release it. However, a project-specific design rule can often be sufficiently different that a checker for it can only be written by programming a special-purpose extension to the tool. Whether it is possible to do so depends on the nature of the rule itself, and the degree of extensibility that the tool provides. Before explaining how this can be done, it is worthwhile to briefly describe how advanced static-analysis tools work.
Advanced Static-Analysis Tools
Static-analysis tools work very much like compilers. They take source code as input, which they then parse and convert to an intermediate representation (IR). The IR typically comprises the program’s abstract syntax tree (AST), the symbol table, the control-flow graph (CFG) and the call graph. Figure 1 shows a block diagram of the process. A compiler uses these to generate object code and then discards them. However, staticanalysis tools retain the IR, and checkers are usually implemented by traversing or querying the IR looking for particular properties or patterns that indicate defects. A checker looking for a simple syntactic property (e.g., goto statements) would search the abstract syntax tree for constructs that match that pattern. The advanced tools get their power from sophisticated symbolic execution techniques that explore paths through the control-flow graph. These algorithms keep track of the ab-

stract state of the program and know how to use that state to exclude consideration of infeasible paths. This level of complexity is required in order to find the serious bugs while keeping the level of false positives low.
Custom Checkers
No two tools provide exactly the same interface or techniques for implementing custom checkers, but two mechanisms are common. The first allows users to essentially annotate their code. The second is an API that gives access to some aspects of the IR, typically using a visitor pattern. We explain the first mechanism using examples written for CodeSonar. Other tools have analogous mechanisms. Suppose, for example, that there is an internal function named foo that takes a single integer parameter, and that it is dangerous for that parameter to have the value -1. A check for this case could be implemented by adding some code to the body of foo as shown in Code Block 1.
The #ifdef construct ensures that this new code is not seen by the regular compiler. The call to csonar_trigger is never actually executed, but is instead analyzed by the tool. If the analysis considers that the trigger condition may be satisifed, then it will issue a warning with the given message. Of course in most cases it is not appropriate to require that programmers interleave these annotations with the code, so there is an alternative way to implement this kind of check that allows it to be written in a separate file, which avoids the need for the code to be edited. This approach would also be useful when the source code for foo is not available, such as when it is in a third-party library. To do this, the author of the checker would write a replacement function as shown in Code Block 2. void csonar_replace_foo(int x) { csonar_trigger(x, “==”, -1,
void foo(int x)
“Dangerous call to foo()”);
{
foo();
#ifdef __CSURF__ csonar_trigger(x, “==”, -1, “Dangerous call to foo()”); #endif __CSURF__ … }
Code Block 1
}
Code Block 2
When the analysis sees the definition of csonar_replace_ foo, it treats all calls in the code to foo (except the one inside csonar_replace_ foo) as if they were calls to csonar_replace_ foo instead.

CompactPCI Plus ®
This trigger idiom is good for checking temporal properties, particularly sequences of function calls. Suppose there is a rule that says that bar should never be called while foo is executing. A check might be implemented as shown in Code Block 3. static int foo_is_executing = 0; void csonar_replace_foo(int x) { foo_is_executing = 1; foo(); foo_is_executing = 0; } void csonar_replace_bar(void) { csonar_trigger(foo_is_executing, “==”, 1, “Call to bar from foo”); bar(); }
Code Block 3
Note that a global state variable is used to record whether or not foo is active. Before entry to foo, it is set to one and then reset to zero after foo returns. This variable is then checked in the trigger in bar, and if set to one, a warning will be issued. The example in code block 3 shows how a global property might be checked. The same mechanism can be used to write checks for properties of objects. For example, it is illegal to read from a file object after it has been closed. In such a case the state being checked must be associated with the file object. The extension API allows users to specify attributes that can be attached to objects. These can be thought of as state variables that can be associated with objects. An attribute can be used to encode whether a file object is open or closed, and the checker for a reader function can test the value of that attribute and issue a warning if the file is in fact closed. This approach allows users to author static checks almost as if they were writing dynamic checks. The API for this kind of check is small, and the language is regular C, so there is a shallow learning curve. This simplicity is deceptive because the technique can be used to implement fairly sophisticated checks. In CodeSonar, many of the out-of-the-box checks are implemented this way.
The second way to implement a custom check is to use the API that gives access to the underlying IR through a visitor pattern. A visitor is a function that is invoked on every IR element of the appropriate type; there are different visitor types for different IR constructs. When they are present, visitors piggyback on the various traversals carried out by the analysis. Visitors can be defined for files, identifiers, subprograms and nodes in the controlflow graph (which correspond roughly to program statements), and the syntax tree. The interface to a visitor allows for pattern matching against the construct. This way a checker author can easily search for constructs without having to know exactly how they are represented. For example, suppose there is a rule that no variable is allowed to contain uppercase characters. The checker for this would be best implemented by writing a function that takes an identifier as input, checks that it represents a variable, scans it for uppercase letters, and issues a warning if one is found. This function would be registered as a visitor for the table of identifiers. CodeSonar has an additional kind of visitor, which is invoked during the path exploration of the control-flow graph. At each step along the path, the check can query the abstract state of the program, so the implementation can ask questions such as “what is the value of this variable at this point?” This allows the checker author to write sophisticated checks that leverage the built-in program analysis capabilities of the tool.

kill of larger motherboards like Mini-ITX. The single-chip Intel US15W chipset provides modest expansion buses and I/O sufficient for controller applications. The board’s feature set includes a Gigabit Ethernet port, several USB ports, eight GPIO pins and a CompactFlash socket on the bottom of the board. Since space is at a premium, pin headers are used for flexible cabling. Only the I/O used by an application is cabled out to the enclosure, and in the locations where desired. SBCs with fixed I/O blocks are convenient but inflexible. Computer-on-Module architectures require custom carrier boards to be designed in order to bring out the I/O, consuming development budgets and extending project risk and schedule. Solid-state drives (SSDs) are gaining in popularity for mass storage. They offer small size, low power, lower MTBF and no spin-up time compared to rotating disk drives. Windows XP Embedded brings the familiar desktop user interface in a modular footprint (image size)—even down to 1 Gbyte and below. For many applications, a 1 Gbyte CompactFlash device is very mainstream and cost-effective, well below the steep part of the flash price curve. A short copper plate with fins spreads the modest heat from the Atom processor and single-chip US15W chipset over the full breadth of the board. The SODIMM RAM memory is also cooled by this heatsink. The thermal solution has a low thermal resistance with minimal airflow inside the system enclosure, allowing operation to +70°C air temperature just above the heatsink. The heatsink can be attached to the outer enclosure in places, further removing heat from the tiny SBC (Figure 2). At the front of Figure 2 are pin headers for two USB ports and one Gigabit LAN port, as well as an IDE connector that can be used in other applications. These connectors are not covered by the copper heatsink so they are easily cabled to the outside of the enclosure.
PoE System Solution
The Jaco Electronics JDS104CA01 (Figure 3) is a new x86based PoE solution with full LCD and touch screen capability. Designed as a wall-mounted user interface to a professional au-
dio control system, the unit includes: 10.4” SVGA LCD, resistive touch screen and 1.6 GHz Atom CPU powered Ampro by an Adlink CoreModule 730. This panel PC system uses only 11 watts, landing safely under the IEEE 802.3 PoE power requirements. The combination of x86 and ultra-low power is the best of both worlds that many have been waiting for. JDS104CA01’s configuration creates a reference design that is suitable for application in industrial, medical and other arenas using LCD sizes up to 12.1” diagonal. Many of today’s panel PCs strive for a fanless, low-powered, high-performance product. While these panel PCs may be low powered compared to some standards, they do not come close to meeting the 12.95 watt PoE requirement. Table 1 compares a typical low-powered panel PC to JDS104CA01. A low-powered SBC is only the first step to designing a highperformance system that is PoE-compliant. As one can see from Table 1, an LED backlit LCD also plays a major role in power savings. The emergence of LEDs in LCD backlighting has allowed for numerous advantages for today’s applications. New high-efficiency LEDs have allowed displays to use less power for the same luminance. For example, an AUO G104SN02 V2 10.4” display with 400 nits of luminance uses 5.2 watts of total power. This is 32% less power as compared to similar displays utilizing CCFL backlights.
Figure 2 The thin heat sink on the ISM board draws heat off the major components and can also be attached to the chassis, allowing operation in +70° C ambient air temperature.
The power savings due to LED backlights does not stop there; LED backlit panels require even less power due to the differences in drive requirements compared to their CCFL rivals. The change from a DC-AC inverter to an LED driver with a constant current circuit allows for a simpler, more efficient solution that does not inherit the EMI problems that accompany CCFL inverters. In fact, many of the latest LED backlit LCDs embed these constant current circuits; this eliminates one more part in the design and simplifies the total solution. The AUO G104SN02 V2 is one example of an LCD with a built-in LED driver circuit. This driver circuit is included in the 5.2W of total power from the LCD and allows the system to eliminate an additional 1.2W that is lost by the inefficiencies of the CCFL inverter.

PoE power board is designed to receive an input of up to 12.95W and supply an output of up to 11.00W. The CAT5 cable entering the unit is the only external cable needed to run the system, making for a clean and elegant solution. The PoE board used in the 10.4� design is 85% efficient and has a PC/104 mounting scheme that can stack on top of the ISM Atom board. Although all low-power components are selected, heat dissipation is still an important design consideration in such an application. Many PoE applications require fanless solutions in sealed enclosures that do not allow for airflow through the unit. Heat sinking and proper enclosure design become critical to the longterm reliability of the product. The Atom-based SBC is designed to use the outside enclosure to help dissipate the heat generated from the SBC. The low-power and customizable solution also allows for the system to be designed to withstand harsh environments or meet many unique enclosure requirements. Although not essential, touch screens often complement many of the current PoE applications in today’s market. Whether it is resistive, capacitive, projected capacitive or any other touch screen technology, touch screens provide a convenient user interface to operate interactive applications. The touch screen also allows for a sleek look by having no buttons on the faceplate, one single in/out wire and no mouse or keyboard. Jaco Electronics (877) 373-5226. Hauppauge, NY.

System Integration Advances in Small Form Factors
Embedded Form Factors Harness Emerging Technologies to Enable Wireless Systems Developments in low-power processors, highly integrated peripherals and new interconnects are shrinking the size and power consumption of modules to allow their deployment in wireless network applications.
by Jason Krueger, VersaLogic

ireless connectivity is merging with technological advancements in silicon, signaling, mass storage and software to meet the high-performance, ultra-low-power requirements for next-generation wireless systems. Embedded form factors, seeking to utilize these developing technologies to the best advantage of system designers, continue to evolve by facilitating emerging standards and providing enhanced capabilities while simultaneously reducing form factor footprints. As wireless connectivity becomes increasingly ubiquitous, the volume of embedded systems that utilize wireless is expanding, thereby perpetuating the demand for higher processing power with minimal power draw and size. Embedded computing systems have long been tethered by wires to a stable infrastructure providing myriad connectivity options and a continuous source of power. For applications where the data is beyond the infrastructure, the solution has often been to build the infrastructure out to the data. Though this approach is feasible in locations where a wired infrastructure exists and the distance to be wired is relatively short, wired connectivity quickly becomes prohibitively expensive as the distance to be wired increases; furthermore, building out infrastructure is an

entirely improbable solution in situations where there is no established infrastructure to begin with. The solution to the limitations imposed by wires is simple—remove the wires. Though this dream of wireless connectivity has existed since the first network packet was sent over a wire, the technology required to facilitate reliable, high-bandwidth, secure data transmission has only recently emerged as a truly viable solution. The continuing evolution and adoption of wireless protocols, including Wi-Fi, WiMax, CDMA, UMTS, LTE, Zigbee and Bluetooth, along with free worldwide access to Global Positioning System (GPS) data, has unleashed an explosion of wireless consumer devices, including smartphones, mobile Internet devices (MIDs), e-books, portable media players and navigation systems. The success of these products has proven the potential for wireless applications while simultaneously fueling the expansion of the infrastructure necessary to sustain them. This has in turn opened the door for sophisticated wireless applications in the embedded systems space that take advantage of increased processing power and expanded system capabilities to revolutionize both existing and emerging embedded applications.
Design Restrictions
The freedom afforded by wireless carries with it inherent design restrictions. Lacking a constant supply of wired grid power, wireless systems typically rely on batteries. Faced with a scarcity of power, stringent control of power consumption is no longer an option but a necessity. Size is also a major design factor, as smaller sizes afford greater mobility. Support for standard interfaces and peripherals is also required to facilitate design implementation, speed time-to-market and keep system costs to a minimum. Wireless systems must also communicate over standard networking protocols and utilize advanced data compression and security functions to minimize bandwidth while maximizing data integrity and security. Wireless systems are often deployed in demanding environments subject to extreme physical and environmental stresses, which necessitates the need for ruggedized solutions with unquestioned reliability, especially in the case of remote applications. RISC architectures, including ARM and PowerPC, have been the preferred choice for wireless embedded devices due to their ultra-low power consumption and superior performance-tocost ratio in the light of application requirements and production

volume. Success naturally breeds competition. While RISC technology continues to drive incremental increases in processor performance, CISC architectures (primarily x86), have been aggressively moving into the wireless embedded systems space through radical decreases in power consumption and package size. Intel and VIA have been aggressively transitioning x86 technology into the wireless embedded systems space. Initially targeted at the netbook market, then at even smaller, lower-power nettop applications, x86 technology continues to find its way into smaller and smaller embedded applications. The second-generation Atom Z5xx processor series (Figure 1) illustrates Intel’s commitment to the exacting needs of nextgeneration embedded systems. Optimized for low power, thermally constrained, fanless, small form factor (SFF) solutions, the Atom Z5xx series offers system designers a true embedded processor solution with processing performance up to 1.6 GHz, extended temperature operation (-40° to +85°C) and long life-cycle manufacturing support. The Atom Z5xx, along with the System Controller Hub (SCH) US15WP(T), provide the processing performance required to deliver next-generation wireless applications incorporating advanced graphics, display, video and audio capabilities, while support for PCI Express (PCIe), USB 2.0, SMBus, I2C, LPC, IDE (PATA) and GPIO provide a wealth of I/O options to support diverse system applications. Advanced power management capabilities enable power to be removed from the processor core and caches while minimizing leakage to significantly reduce idle power. Intel is pushing deeper into the wireless embedded systems space as it transitions its System on Chip (SoC) designs to an Atom processor core, providing designers with a broad array of purpose-built processors that share a common core, yet have differentiating features that can be mapped to system requirements for speed, power and temperature range. SoCs further minimize space by combining typical two- and three-chip solutions into a single integrated chip. Originally targeted at MIDs, the addition of Intel QuickAssist Technology will appeal to wireless applications through the acceleration of cryptographic and packet processing to facilitate virtual private network (VPN) gateways, firewalls and Unified Threat Management (UTM). Further size and power reductions to the x86 architecture will continue to be achieved by building on the success of 45nm process technology, with the promise of 32nm process technology looming just over the horizon.
including PCI Express (PCIe), ExpressCard, USB 2.0, SMBus, I2C and LPC, as well as control and power management signals. Additionally, interconnects must be ruggedized for high shock and vibration environments. Smaller connector heights enable denser designs, further reducing the overall system volume. Finally, interconnects must be low cost in order to be viable for original equipment manufacturers (OEMs) in production quantities. Several new interconnect standards have emerged to meet these demands for wireless embedded systems. Some connectors, such as MXM, have been adapted to the embedded space after having proven themselves in the notebook sector. Others, such as Stackable Unified Interconnect Technology (SUMIT) from the Small Form Factor Special Interest Group (SFF-SIG), have been built from the ground up to meet the exacting needs of embedded systems development. Wireless embedded systems typically use a solid-state drive (SSD) for mass storage. Compared to hard disk drives, SSDs offer substantial power savings. Furthermore, as SSDs have no moving parts, they are less susceptible to the effects of shock and vibration. Secure latching connectors further increase reliability in mission-critical applications. SSD capacities are continually expanding, while extended temperature and conformal coating options are emerging to satisfy the needs of demanding environments. SSDs can be interfaced via parallel ATA (PATA), serial ATA (SATA), USB or PCIe, offering system designers the ability to target their system throughput requirements. CompactFlash, which has long been the standard for embedded systems, is now beginning to be displaced by these new offerings, including Disk on Module, eUSB, SSDDR and the new MiniBlade specification from the Small Form Factor-SIG.

Interconnects and Storage
As silicon technology advances to increase the amount of processing power available to embedded systems, so does the sheer amount of data that needs to flow in and out of these systems. Multiple simultaneous inputs (GPS, video cameras, microphones, sensors, accelerometers, etc.) and outputs (wireless data transmission), along with a rich user interface (high-definition video and audio), combine to put demanding I/O throughput requirements on wireless embedded systems. To meet these needs, advanced I/O connectors are emerging that offer an array of both high- and low-speed signals to meet the diverse needs of wireless embedded systems. Robust signal support is required, typically

ing that takes advantage of advancements in power efficiency, thermal management, and feature integration to enable ultracompact, stackable board solutions. The Pico-ITXe specification, originally proposed by VIA, has been adopted by the SFF-SIG specifically for the development of energy-efficient, fanless, x86 systems with a complete range of standard signaling on a 100 mm x 72 mm form factor. Pico-ITXe (and its complementary Pico-I/O specification) utilizes the SUMIT interface while also providing a standardized, modular, SFF expansion specification. The SFF-SIG is also bringing the benefits of SUMIT to the industry-standard 90 mm x 96 mm footprint popularized by PC/104, thereby opening the door to high-speed signaling via PCIe and SATA, with the added versatility of ExpressCard, while retaining legacy signal support. A size comparison of several major form factors is shown in Figure 2.

Form Factors
Evolving form factors are synthesizing the hardware requirements for wireless embedded systems into a standardized development platform, thereby enabling innovation, reducing risk and speeding time-to-market. Taking advantage of reduced processor package sizes, form factors continue to decrease in size, enabling increasingly smaller embedded systems for wireless applications. Computer-on-Modules (COMs) allow a modular systems approach that decouples the processor complex from the remainder of the system, thus alleviating system obsolescence as imposed by Moore’s law. The benefits of a modular approach have led to a proliferation of specifications. The nanoETXexpress specification is a variant of the COM Express standard PICMG, which adds support for PCIe, Gigabit Ethernet (GbE), USB 2.0 and SATA while retaining legacy signal support on a reduced 55 mm x 84 mm form factor utilizing a standard COM Express Type 1 connector. Another variant of the COM approach is the Qseven specification from the Qseven Consortium, which utilizes standard high-speed MXM connectors to provide high-speed serial signals on a 70 mm x 70 mm form factor. The SFF-SIG, on the other hand, has taken a fresh approach to COM development with the introduction of its Computer on Module Interconnect Technology (COMIT) specification. Rather than focusing on a particular form factor, COMIT is a modular, processor-independent connector system that supports both emerging and legacy signaling common to modern low-power chipsets by way of a rugged, highdensity 240-pin connector pair that meets the bandwidth requirements for next-generation PCIe 2.0 and USB 3.0 signaling. A new generation of mainboard form factors is also emerg-

The critical role that software plays in the control of power consumption cannot be understated. The Advance Configuration and Power Interface (ACPI) specification is an open industry standard that provides industry-standard interfaces for application control of hardware sleep, performance and throttling states. By proactively controlling the sleep states of hardware via software, system developers are able to reduce power consumption to a fraction of typical system levels. Because entering and exiting deeper power-saving states increases system latency, the ability to invoke the full range of both processor and system sleep states afforded by emerging processors enables power benefits to be adaptively fine-tuned to application performance as needed. ACPI also enables systems to control device states for powering down auxiliary peripherals when idle, further reducing system power consumption for maximum efficiency and battery life. The open source community, through projects such as Mobile Linux and LessWatts, is contributing best practices and creating standards to realize even greater power savings and accelerate wireless embedded development. As wireless connectivity proliferates and the processing power available to SFF embedded systems increases, new opportunities are emerging to deliver innovative solutions that harness the true potential of wireless applications. To facilitate these solutions, embedded form factors are evolving to provide open platforms that meet the demanding needs of wireless applications while also providing the flexibility required to adapt to a diverse array of solution possibilities (Table 1). The future of wireless is at hand—all that remains is to realize its full potential for the benefit of humankind. VersaLogic Eugene, OR. (541) 485-8575. [www.versalogic.com].

TECHNOLOGY FEATURED PRODUCTS “Energy Optimizer” Lets Data Centers Conserve Energy While Meeting Efficiency Goals A wireless monitoring system provides continually updated information on a data center's electrical usage and thermal status, giving users the precise knowledge to take energy-conservation measures while maximizing the operational efficiency and reliability of their servers and other computing equipment. The Arch Rock Energy Optimizer-Data Center Edition (AREO-DC) measures both power and cooling system efficiency in the data center using non-disruptive Internet Protocol (IP)-based wireless sensor networks. It lets data center managers: identify the factors that cause energy waste (e.g., short-cycling, missing blanking panels, sub-floor obstructions) or "hot spots" and other harmful conditions, and correct these problems to reduce existing power consumption or allow the facility to support more equipment. They can then optimize available capacity for new servers based on the actual electrical/cooling consumption of equipment, rather than the overstated "nameplate" ratings. AREO-DC works by deploying wireless sensors to measure electrical, thermal, flow and pressure conditions on power circuits, server racks, computer-room air conditioners (CRACs) or air handlers (CRAHs), chillers and underneath the raised computer-room floor. The sensed data is then transmitted via wireless sensor networks to a graphical, multiwindow dashboard that shows the electricity load (and associated utility rate-adjusted spend rate) of various equipment, electricity usage by physical or functional area over user-selected time intervals; temperature and humidity data from CRACs, CRAHs, server racks and chillers over time; chiller water-flow rates; "heat maps" superimposed on a floor plan; and key performance indicators such as the Green Grid organization's Power Usage Effectiveness (PUE) Level 3 standard. From the AREO-DC dashboard, users can drill down to specific data centers and specific racks within a data center, and bring up side-by-side views of various factors, such as energy usage vis-à-vis indoor and/or out-

door temperature. Alerts can be generated when heat- and energy-use thresholds or userdefined financial thresholds are exceeded. AREO-DC can help data center managers, for example, pinpoint improper mixing of hot and cold air such as conditions that may lead to insufficient cold air pressure at rack inlets, top-of-rack hot spots, or cooling-plant overcompensation. It can verify the existence of short-cycling or conditions that cause suboptimal CRAC/CRAH operation. In addition, it can obtain an accurate PUE figure in mixeduse environments by measuring the cooling load of the data center relative to that of the entire facility, and combining this with measurement of the central cooling plant's electrical consumption. And it can measure outside air temperature and humidity to identify air or water free-cooling opportunities through the use of HVAC economizers or cooling towers rather than costly use of compressors and refrigerants. Data from the various sensor nodes is

Robust Dual Gigabit Ethernet Mezzanine Board with Long-Term Availability
A new dual Gigabit Ethernet mezzanine board enables all VPX, VME, CompactPCI and custom boards offering a PMC or XMC slot to be extended by two Gigabit Ethernet interfaces, which can be individually routed to the front or to the backplane. Equipped with the high-end Intel 82571 Dual Channel Ethernet Controller, the XMC-ETH2 mezzanine board from Kontron delivers very high data throughput. The new mezzanine board comes in two versions: air-cooled (Standard Commercial (SA)) or conduction-cooled (Rugged Conduction Cooled Version (RC)), in order to suit the individual needs of different system environments. Kontron’s dedicated long-term supply (LTS) program offers customers 10+ years of guaranteed supply, making the Kontron XMC-ETH2 a suitable Ethernet mezzanine for infrastructure programs. Typical application areas can be found in markets such as medical, transportation, military, aerospace, energy and automation. Because the XMC-ETH2 mezzanine board supports both XMC and PMC extension slots, it can be used universally in different system designs. Designed as a Plug & Play solution, the board automatically selects the data bus according to whether the power supply is present on the P5 connector (x4 PCI Express). Otherwise, it switches to 32-bit PCI 33 MHz or 66 MHz on the PMC connectors. An integrated micro DIP switch allows for manual override of the host bus selection. Another micro DIP switch controls Ethernet channel routing to the front panel (RJ-45) or to the backplane (P4). Each channel can be routed separately. The Kontron XMC-ETH2 dual Gigabit Ethernet mezzanine board supports Linux, VxWorks and Windows XP and is available now: the SA version for air-cooled system designs in a temperature range of 0° to 55°C (VITA 47Class AC1) and the RC version for robust conduction-cooled systems in the extended temperature range of -40° to 85°C (VITA 47-Class CC4).

Dual PMC Expansion on Core2 Duo VME Carrier Card
Many long-life VMEbus systems require high-performance expansion using PMC or XMC modules. Xembedded has announced the XVME-9076 dualPMC 6U carrier module. The XVME-9076 single-slot dual PMC carrier provides support for two additional PCI/PCIX sites to the Xembedded XVME-6200 Core2 Duo VMEbus processor. The XVME-9076 expands the XVME-6200 processor to support up to three PMC modules or two PMC modules and one XMC module for functions such as FPGA, Ethernet, SCSI, serial port, digital I/O, analog I/O and special-function PMC modules. The PCIe x4 is a high-speed connection in each direction between the XVME-9076 and the XVME-6200 processor. The XVME-9076 is compatible with PMC 2.0 specifications for IEEE P1386 modules. The XVME-9076 offers two 32/64-bit, 66/133 MHz sites, one with rear I/O out P2 of the carrier and the other site with rear I/O out the optional P0. Both PMC sites are capable of providing 14 watts of power. The XVME-9076 expansion module is available in commercial and air-cooled versions. Xembedded, Ann Arbor, MI. (734) 975-0577.
