SDR in the News
Complete SDR Development Platform Released
A development platform containing all hardware and tools required for software-defined radio development has just been released. Compliant with the Software Communication Architecture (SCA) mandated for all future U.S. military radios, the Pentek SCA 2510 hardware platform consists of a Pentek 7640 software radio transceiver PCI card installed in a PC workstation. The computer is loaded with the Linux operating system, development tools and the SCARI++ SCA core framework from Communications Research Centre, Canada . The PCI card comes pre-configured with drivers and libraries so developers can immediately begin their software-defined radio projects. The SCA Architecture mandated by the Joint Tactical Radio System (JTRS) program office provides a software framework for the implementation of software defined radio platforms. This framework includes a common operation environment and a set of common services and standardized component interfaces. The Model 7640 Dual Channel Transceiver PCI board digitizes HF or IF input signals using a pair of 14-bit, 105 MHz A/D converters and generates output signals with two 16-bit, 500 MHz D/A converters. The 7640 is also equipped with a Virtex-II Pro VP50 FPGA that serves as a control and status engine with data and programming interfaces to each of the many onboard resources, including a four-channel digital downconverter, a digital upconverter, and a clocking and synchronization system. A 64-bit 66 MHz PCI interface includes a high-performance nine-channel DMA controller to boost PCI bus transfer speeds. Pentek, www.pentek.com .
New FPGA Technology Supports SDR Waveform Portability and Reuse
PrismTech recently demonstrated how a CORBA ORB can be embedded natively in an FPGA and used to control logic within the FPGA. As a middleware technology, the Spectra ICO (Integrated Circuit ORB) eliminates the need to develop custom proxies on General Purpose Processors (GPPs) and Digital Signal Processors (DSPs) that simply serve to establish communication to waveform objects residing within FPGAs. These proxies (sometimes referred to as Hardware Abstraction Layers or HALs) have been used when designing to SDR architectures such as the Software Communications Architecture (SCA) and are meant to increase portability and re-use, but in practice can increase latency, reduce throughput, and lower re-use potential. Spectra ICO eliminates any need to embed GPP cores into FPGAs in order to offer software ORB capability. The Spectra ICO demo equipment consists of a PC running the client code and an Altera Cyclone II development board that hosts the FPGA. The software running on the PC generates a CORBA GIOP message bound for the ICO, encapsulates it in an Ethernet frame and transmits the packet to the demonstration board. An Ethernet controller on the Altera FPGA demo board receives the packet, strips off the Ethernet encapsulation and passes the GIOP message to the ICO residing within the FPGA. The ICO processes the message, extracts the data in the message body and transfers it to the internal logic blocks of the FPGA representing the custom signal processing design blocks of an SDR waveform. If required by the CORBA message, the ICO generates and sends a reply message back to the client on the PC. Spectra ICO utilizes approximately 5% of the logic elements of an Altera EP2C35 and no memory blocks. PrismTech, www.prismtech.com .

New Embedded Wireless Technology for Military Diagnostics
A new embedded sensor concept is nearly ready for use in advanced military vehicle diagnostics. Unveiled two weeks ago at the Defense Maintenance Symposium in Birmingham , Alabama , Solidica's new prototype sensors were created in collaboration with Freescale Semiconductor. Directly embeddable into any metal component, the sensors are able to measure a wide range of critical system health information and wirelessly convey the data to the platform in real time using Freescale's 2.4 GHz digital radio and microcontroller technology based on their ZigBee compliant platform. These data can then be used to make immediate tactical decisions at the operational level and can further be leveraged by the military in support of automated logistics activities as part of their emerging Sense and Respond initiatives. The enabler for these small rugged sensors is Solidica's ultrasonic consolidation technology. Solidica fabricates their sensors using thin strips of metal, one layer at a time. Periodically, electronics and/or sub-millimeter integrated features are inserted between the layers during fabrication, drawing energy from their environment and allowing for an invisible monitoring capability that cannot be removed or easily destroyed. Solidica, www.solidica.com.
PCI Express Frame Grabbers Debut
With the new National Instruments PCIe-1430 image acquisition board, engineers and scientists can now use a single board to acquire images from two independent base-configuration Camera Link cameras. Using PCI Express, the board can acquire images from two cameras at speeds up to 255 MB/s and clock rates up to 85 MHz, the maximum defined by Camera Link. PCI Express bandwidth ensures reliable frame transfer with both cameras operating at full resolution and maximum frame rate. Traditionally, engineers and scientists performing multi-camera inspections through a PCI bus with data rates more than 100 MB/s had to purchase multiple computers and multiple Camera Link frame grabbers. With the introduction of PCI Express and the NI PCIe-1430 image acquisition board, these engineers and scientists can now acquire high-speed data from two independent cameras through a standard PC bus. The NI PCIe-1430 board can obtain information from cameras with different formats, resolutions, speeds and bit depths. Additionally, several NI PCIe-1430 boards can be used together in a single PC to acquire gigabytes of images per second. National Instruments, www.ni.com .

Sensors and MEMS
MEMS (micro electro-mechanical systems)—an acronym barely heard of a decade ago—have been having a profound impact in a variety of sensor applications. From relatively simple pressure sensors to complete chemical analysis systems, MEMS are used in a very broad cross-section of military devices from checking airspeed, wing deflection, surface conditions and performing chemical analysis on everything from suspected contaminated areas to fuel/air mixtures. They also play a key role in many other kinds of military electronic systems including data collection sensors for radar, sonar, SIGINT, or sensors used as navigational gyroscopes and munitions guidance. And because MEMS are basically manufactured as semiconductors, they have the inherent robustness and long lifetimes required by such systems. This feature section explores the current and future state of sensor and MEMS technologies as they apply to the military.
Safety-Critical Software Standards
The military and aerospace industry mandates rigorous technical and process requirements for safety-critical computing. Such capabilities emerged a couple years ago as a few scattered announcements supporting safety critical software standards such as DO-178B and ARINC-653, but they're now an entrenched part of the embedded OS vendor's offerings. Articles in this section update readers on those standards and how they're being implemented and applied to a variety of mission-critical systems.
PCI Express Analyzers
PCI Express certainly wasn't the first switched fabric technology to enter the mix, but as it moves onto servers and desktop PCs it's already becoming the most ubiquitous. And it's rapidly moving into the embedded-computer space. PCI Express is quickly becoming a backbone of performance-based embedded systems, and, while many sub-systems take some of the work out of tracking the flow of data, there are several PCI Express bus analyzers that can make any development and debug task faster and easier. This Tech Focus section provides an update on PCI Express analyzer trends, and provides a product album of representative PCI Express analyzer products.
Mass Storage
If the dynamics in the flash memory chip market and the roadmaps of flash chip vendors are any guide, it looks like flash-based solid-state disks (F-SSDs) are poised to quell any arguments for staying with traditional rugged hard drives. Throw in the major advantages of ruggedness and security that F-SSDs enjoy and the contrast becomes even more pronounced. Because F-SSDs targeted for military and aerospace apps use the same fundamental flash components as the consumer realm, the price advantages can be leveraged across all markets. Traditional problems with Flash-based disks are quickly falling by the wayside. Random access speeds rival and will soon beat other media, retention and re-writing cycles have dramatically increased and many systems offer a single-control “erase all” function with or without power for security-sensitive applications. Articles in this section examine the key technology trends affecting the use of F-SSDs in military applications. back to top
