Virtex-4: World's Fastest FPGAs Now Even Faster With New Speed Grade Files

February 23, 2005 -- Xilinx, Inc. (NASDAQ: XLNX) today announced that it has released software timing files for the fastest speed grade of its Virtex™-4 multi-platform FPGA devices. Designs implemented using the latest version of the Xilinx industry-leading ISE software tools and this new timing information clearly demonstrate that Virtex-4 FPGAs are the industry's fastest, out performing competing FPGAs in every performance category:

• 1.6x higher LVDS I/O bandwidth
  
• 3x higher memory interface bandwidth
  
• Only 90nm FPGA with high-speed serial I/Os
  
• 1.2x higher on-chip RAM speed
  
• 1.4x higher DSP performance with 32-tap FIR filter example
  
• 3x higher embedded processing performance
  
• 1.1x faster logic performance

A free web seminar, demonstrating the performance advantages of Virtex-4 multi-platform FPGAs is available for designers, visit www.xilinx.com/virtex4/performance for more information.

Xilinx has invested significant effort in developing a methodology that fairly and accurately measures logic performance on real customer designs. A good methodology must correctly constrain both the synthesis and place and route tools, evaluate the most important clock in the design (not only the slowest clock), use equivalent switch settings for each tool, and compare similar speed grades for each device. This accurate methodology shows a logic fabric performance advantage for Virtex-4 FPGAs of up to 70 percent, and on average 10 percent as compared to competing FPGAs.
