Radiation-Tolerant FPGAs

October 1, 2008

Xilinx (San Jose, CA) has introduced radiation-tolerant Virtex®-4QV field programmable gate arrays (FPGAs) for processing needs of video, audio, radar streams, and packet processing functions in space applications. The FPGAs feature reconfigurable logic fabric, built-in memory, embedded computing, and digital signal processing on a single chip. The devices provide system integration among FPGA-based offerings for space applications with up to 200,000 logic cells, 10-Mbit of RAM/FIFO, two built-in PowerPC® processor blocks with auxiliary processing unit controller, 512 DSP slices, and four built-in Ethernet MAC blocks.

Upset mitigation features address environmental circumstances such as charged particles that can alter the state of configuration elements within the FPGA, causing a single-event upset that produces adverse effects on the FPGA. These features include triple modular redundancy reference designs, and the Xilinx TMRTool to automate logic triplication in the FPGA fabric.
