Supercomputing Wings Course Toward FPGAs and Fabrics
Jeff Child

Supercomputing technology—in both embedded systems and installation-based systems—ranks as a vital segment in today’s military. FPGA reconfigurable processing and switched fabric interconnects provide the building blocks for future system developments.

Reconfigurable Processing Design Suits UAV Radar Apps
Peter Buxa, Applications Technology Manager AFRL Sensors Directorate David Caliga, Computer Engineer SRC Computers

UAV-based radar electronics require supercomputing performance in a compact space. A reconfigurable computer architecture offers the compute density to fit the bill.

FPGA Supercomputing Gets Practical for Defense Apps
Malachy Devlin, Nallatech

Moving military computing applications to FPGA platforms calls for a change in development workflows. Tools help automate the design of data flows for complex multi-FPGA implementations.

POS/NAV/GPS and Timing

Keeping Precision Time When GPS Signals Stop
Bruce G. Montgomery, Syntonics

Most military GPS-based timekeeping systems are vulnerable to signal outages caused by unintended malfunctions or interference from enemy threats, because they rely on a single quartz oscillator for holdover timekeeping. A reliable, robust time and frequency source is needed to sustain operation for mission-critical navigation and communication systems.

Emerging Tiled Processor Trend Rivals SMP Approaches
Jeff Child

Compute-intensive military systems are riding the trend toward multi-core processors. Emerging choices in tiled processing architecture offer an alternative to symmetric multiprocessor schemes.

Cell Technology Enables New Defense Applications
Craig Lund, Mercury Computer Systems

Designed for next-gen digital media apps, the Cell processor has hooked interest among image processing designers for automatic target recognition and related apps.

Multi-CPU System-on-Chip Advances Solve Obsolescence Woes
Steve Manuel and Gail A. Walters, CPU Technology

IC advances now make multi-CPU system chips practical. Applying such technologies empower military system designers to make an end run around numerous component and subsystem obsolescence concerns.

CompactPCI Passes Muster in Military Programs
Ann R. Thryft

As military systems houses turn to board vendors for sophisticated electronics, they are demanding CompactPCI in ever-greater numbers. In response, more specialized board functions are appearing and more conduction-cooled 3U and 6U products are available for air-, ground- and sea-based combat systems, as well as space systems.
