Power-Saving Embedded Board (VersaLogic)

VersaLogic Corp. (Eugene, OR) and General Software, Inc. introduced a power- saving feature on VersaLogic’s PC/104-Plus platform, the Puma. The Suspend- to-RAM function (ACPI S3) of General Software’s Embedded BIOS®2000 allows the system to wake up and resume processing in seconds. The board consumes less than 1 W of power in Suspend-to-RAM mode.

Graphics Display Processor (GE Fanuc Embedded Systems)

GE Fanuc Embedded Systems (Albuquerque, NM) offers the 3U VPX MAGIC1 Rugged Display Processor, an integrated sub- system consisting of the 2.0 GHz Intel Core Duo processor-based SBC340 sin- gle board computer and GRA110 graphics processor. The MAGIC1 rugged subsystem lets system designers develop and deploy more sophisticat- ed display applications than has previ- ously been possible. The graphics dis- play processor supports VAPS, GL Studio, and iData display software, and targets embedded training, digital mapping, and vehicle display applications. The MAGIC1 is the first of several planned system-level 3U VPX platforms from the company, each designed to serve specific functional needs.

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.

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.

Fanless Single Board Computer ( ADLINK Technology)

The NuPRO-796 from ADLINK Technology (Irvine, CA) is a half-size board computer featuring an AMD GeodeTM GX 533 processor. Fanless, the device has a 1.1 W CPU power consumption, and includes an on-board 128 MB memory on a single SODIMM slot, one UltraATA 66 IDE connector, and four Serial ATA connectors with RAID support. With several display options, it supports VGA/CRT monitors (1,600 ×1,200, 16 bbp at 85 Hz or 1,280 ×1,024, 24 bpp at 85 Hz), TFT LCDs, (1,280 ×1,024 bpp), and LVDS. Key I/O interfaces include an ACPI-compliant 10/1000BASE-T LAN port, four USB 1.1 ports (two USB ports on the faceplate, two by the pin header), and integrated audio controllers with an AC’97 interface. Operating temperature ranges from 0 to 60°C (storage temperature is -20 to 80°C).

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.
