Multicore Tools for Embedded Systems — Staying Ahead of the Game —

Building a multicore system means dealing with non-determinism. Interactions between tasks running on different cores can occur in a different order, and at a different rate from one run to the next. This makes it harder to reproduce, find, and fix bugs. It also lowers the probability that validations and QA have caught all problems.

Redesigning COTS Servers for Military Applications

Military and ISR operations are inundated with vast amounts of data collected from an expanding network of sources, including sensor data from UAS, satellites, and remote monitoring stations. Critical information must be processed quickly and reliably, and delivered in real time to command centers and forces on the battlefield. Processing this plethora of information requires a multitude of computers, many of which are outdated or on proprietary platforms. To remain sustainable, systems used for enterprise computing, field operations, warfighting, and command and control, must be continually upgraded or replaced. Many of these systems need to be integrated, consolidated, and securely linked to multiple networks.

When the Going Gets Tough...

The theaters of operation for marine, air and land vehicles continue to redefine the term “rugged environment.” No longer bound by on-board human operators, autonomous and unmanned military vehicles are now free to operate within unparalleled temperature, vibration and shock regimes. The limitation on survivability of such vehicles is defined primarily by the robustness of their internal electronics. To meet these challenges, suppliers of hardened electronic systems must employ various ruggedization techniques.

Chassis Mount Power Supplies

XP Power (Sunnyvale, CA) has announced the VCS series of chassis mount single output AC-DC power supplies aimed at cost sensitive industrial applications. The series comprises 50W, 70W and 100W models and are available with +5, +12, +15, +24 or +48 VDC outputs. A user accessible voltage trim control provides a +/- 10% adjustment of the output voltage allowing for the use of non-standard voltages or to compensate for cable losses. The VCS series accommodates the full universal input range from 90 — 264 VAC without derating, and can provide full output power from -10 degrees C to +50 degrees C without derating, and with derating to +70 degrees C. Start-up is from -20 degrees C.

Flat Panel PC

WinSystems (Arlington, TX) has introduced the PPC3-G-6.5, a 6.5" open frame, color, flat panel PC based on a PC/104-Plus single board computer (SBC) that operates from -20°C to +70°C. It includes a resistive touch screen integrated into an aluminum, corrosion-resistant chassis about 2" thick; the open frame chassis (without a front bezel) permits flexible mounting of the system for OEMs and integrators with content-rich applications. It is suitable for instrumentation, industrial automation, and control applications with tight system integration and minimal space requirements. The outdoor-use, 6.5" diagonal color TFT flat panel display features a resolution of 640 × 480 pixels, and a high luminance of 500 cd/m2 (nits) and uses two long-life CCFL lamps that are user-replaceable. The display has a contrast ratio of 600:1, while the screen offers an anti-reflective coating.
