On-Chip Debugging Emulator (Renesas Technology America)

Renesas Technology America, Inc. (San Jose, CA) offers the E8a emulator, an onchip debugging emulator for developing embedded systems that use Renesas microcontrollers. It allows referencing and modification of memory, on-chip I/O, and memory contents while a program is being executed. The tool allows C source-level debugging to be carried out with a microcontroller in the M16C, H8/Tiny, or H8/Super Low Power series, operating at full speed in the system. The device also can be used as a programmer to load code into the internal flash memory of many Renesas microcontroller families. The programming voltage range is 1.8 to 5 V, and the unit features a clock oscillator to enable asynchronous communication in line with a microcontroller's operating frequency. The case measures 92 × 42 × 15 mm.

Multi-Cores: The Gateway to Next-Gen SBCs and Blades

With the introduction of Intel Core microarchitecture into embedded systems, history could very well repeat itself. The company that invented the microprocessor in 1971 and created the very first micro-controller in 1976 is about to revolutionize the embedded space once again. By bringing the power of parallel processing to embedded developers in an open-standards-based building block architecture, Intel is hoping to break down the cost barriers while taking embedded systems performance to new levels that once were reserved only for expensive computer systems specifically designed for symmetric multiprocessing (SMP), while also accomplishing unrivaled levels of efficiency.

Beamforming System Eases Crowded Wireless Spectrum

Beamforming is critical to enable initiatives by the U.S. Federal Communications Commission (FCC) to increase spectrum capacity and provide additional cellular service and coverage through satellite and terrestrial systems. The key technology for this application is beamforming, which electronically steers data streams to and from a satellite via a combination of an array of antennas on the satellite and very sophisticated, ground-based computational engines.

SOA in Practice: Model-Driven Repositories Fill the Gap Between Concept and Implementation

In the past, network-based applications were pretty simple. A networked server ran a monolithic application that users accessed via a basic GUI (graphical user interface). Today, organizations struggle to develop feature-rich, network-based applications while also facing business pressure to minimize timescales, maximize quality, and work with legacy systems hosted on different platforms.

How to Design an Embedded RDBMS Search

As the cost of micro-disk and NAND Flash continue to drop, devices are storing more and more data. It is common now for a person's MP3 player to have more storage than their laptop. But this increase in storage capacity has not been matched with advances in the user interface. Typically, users still wrestle with a folder-based interface to find the data they want, searching by a few vendor-defined categories such as artist, album, and genre. But a new class of embedded database manage- ment systems (DBMS) is emerging to allow end users to search the way people think, rather than in this stat- ic manner. With a RAM footprint ranging from a few tens to a few hundred kilobytes, these products enable developers to deliver this sophisti- cated search on mobile devices. So how do they work? How do you write an embedded application to use a relational DBMS (RDBMS)? While there are a few kinds of DBMS, the relational model has tri- umphed over all the others, largely because it abstracts the data struc- tures so that applications don't have to know them. A relational database management system offers a standard, high-level query language that allows access to data by content, not by pointer or location and offset.

Open-Standard Multicomputers Address Next-Generation Multi-Function Radar Applications

Next-generation radar applications will drive performance demands that will have architectural implications for radar computing and electronics. Advanced multi-function radar (MFR) systems, which will be deployed in harsh and demanding environmental conditions inside unmanned aerial vehicles (UAVs), manned aircraft, and ship- and ground-based radar systems must simultaneously provide multi-mode search, multi-target tracking, synthetic aperture radar (SAR) imaging, and space time adaptive processing (STAP). Both the performance and ruggedization requirements make it challenging to service MFR applications using yesterday's commercial- off-the-shelf (COTS) technologies.

WIN-T: The Warfighter's Communications Backbone for Today and Tomorrow

The battlefield of the future will integrate all elements into one networked force, enabling communication among soldiers and commanders on the land, at sea, in the air, and at fixed command posts. Developed by a team led by General Dynamics C4 Systems and Lockheed Martin, the Warfighter Information Network - Tactical (WIN-T) project is the tactical communications backbone for the warfighter, both today and for the future. WIN-T supports voice, video, and data applications, enabling the soldier to stay connected anytime and anywhere by providing mobility and reliable bandwidth. Leveraging communications technologies such as cellular, wireless LAN, satellite, and VoiceOver IP, WIN-T links weapons, intelligence, surveillance, and reconnaissance, while remaining mobile, scalable, modular, and secure.

A Predictive Model for Cognitive Radio

A computational model that predicts effects of changing operational parameters of a cognitive radio has been developed as part of continuing research on cognitive / software - defined radio (C/SDR) data-communication networks. The term "cognitive radio," "software-defined radio," or "smart radio" denotes a radio transmitter, receiver, or transceiver, (1) much of the functionality of which is implemented in software and (2) that is able to reason about its configuration on the basis of requirements and its environment.

Metamaterials for Advanced Microwave Antennas

A report discusses a research and development project that has made contributions to the art of metamaterials for directing electromagnetic radiation at frequencies of the order of several gigahertz. The next-generation metamaterials expected to emerge from this and related projects could enormously improve the performances of microwave radar and communication antennas.

Accelerated Evaluation of Properties of Polyphase Alloys

A methodology for accelerated evaluation of mechanical properties of polyphase alloys is based on digital representations of the alloys. For a given alloy material system, this representation is utilized in concert with (1) software tools and probes that simulate traditional laboratory testing equipment and instrumentation, and (2) real laboratory mechanical testing by nontraditional methods.
