The radiation-tolerant Virtex-4QV family, from Xilinx Inc. (Nasdaq: XLNX), is the first FPGA solution for space applications to offer multiple platforms optimized to meet the stringent high-performance processing needs of video, audio, radar streams, and packet processing functions. In addition to the high-performance reconfigurable logic fabric and abundant built-in memory, Virtex-4QV FPGAs incorporate advanced embedded computing and digital signal processing (DSP) technology in a single chip. This enables designers of spaced-based digital electronics to reduce system size, weight and power consumption while accelerating development and eliminating the risk and NREs associated with application-specific integrated circuits (ASICs).
The Virtex-4QV family is now shipping with the XQR4VLX200, XQR4VSX55, and XQR4VFX60 devices available for order today in a variety of package options. The XQR4VFX140 device will be available for order in the third quarter of 2008.

To meet the unique processing requirements of space-based systems, Xilinx selected four of the highest performance, largest capacity devices across the three Virtex-4 platforms for its new Virtex-4QV family. These devices provide an unprecedented level of system integration among FPGA-based offerings for space applications with up to 200,000 logic cells, 10Mbit of RAM/FIFO, two built-in PowerPC(R) processor blocks with auxiliary processing unit (APU) controller, 512 DSP slices, and four built-in Ethernet MAC blocks.
All Virtex-4QV FPGAs are guaranteed for radiation tolerance, making it possible for aerospace designers to take advantage of high-performance, high-density reprogrammable technology. Extensive testing by Xilinx and the Single Event Effects (SEE) Consortium verifies a total ionizing dose (TID) of 300 krad (Si) and single-event latchup (SEL) immunity greater than 125 MeVcm2/mg with Virtex-4QV devices. The SEE Consortium was founded in 2002 when Xilinx joined forces with NASA’s Jet Propulsion Laboratory at the California Institute of Technology, leading the way to the application of SRAM-based reconfigurable FPGA technology in high-radiation environments.
The Virtex-4QV family is supported with a range of upset mitigation solutions to address environmental circumstances, such as charged particles (e.g., heavy ions or protons), that can alter the state of configuration elements within the FPGA, causing a single event upset (SEU) that produces adverse effects on the expected FPGA functionality. These solutions include triple modular redundancy (TMR) reference designs, extensive application notes that simplify the implementation of advanced configuration memory scrubbing techniques, and the Xilinx TMRTool to automate logic triplication in the FPGA fabric. The TMRTool not only increases productivity with fast, error-free design triplication, but also streamlines the integration of custom-built TMR modules while giving designers control over how the design is triplicated.
