XILINX SHIPS VIRTEX-4 SX55 - WORLD'S FASTEST FPGA FOR DSP

Xilinx, Inc. (NASDAQ: XLNX) today announced the immediate availability of its Virtex-4 SX55 FPGA - the world's fastest and lowest power FPGA for digital signal processing (DSP) applications. The SX55 device delivers a whopping 256 billion multiply-and-accumulate per second (MAC/s) processing performance,,3 times more than any competing FPGA. Furthermore, the device features power saving process and circuit design technology that reduces static power consumption by up to 76% and dynamic power consumption for the MAC function by more than 20% compared to the closest competing 90nm FPGA. The Virtex-4 SX55 is the sixth member shipping from the Virtex-4 FPGA family and the second device shipping from the DSP optimized Virtex-4 SX platform. With its performance, power and cost advantages, the Virtex-4 SX family is the ideal co-processor for programmable DSPs in real-time signal processing systems.

The Virtex-4 SX55 FPGA provides:

• 10 times higher performance/price ratio compared to previous generation FPGAs, enabled by the revolutionary ASMBL architecture
  
  
• 256 billion MAC/s processing performance enabled by 512 XtremeDSP™ slices each performing 18x18 bit multiply and 48-bit accumulate operations at 500 MHz
  
  
• Industry's lowest in-rush, static and dynamic power consumption with first 90nm triple-oxide technology, embedded IP functions and power-saving configuration circuitry
  
  
• Unique "micropower" architecture consuming a mere 2.3mW/100MHz per XtremeDSP slice

The Virtex-4 SX55 device is supported by the industry's widest range of pre-engineered DSP algorithms and familiar DSP design tools, including the Xilinx System Generator for DSP design and verification tool.

Virtex-4 FPGA Availability
Virtex-4 LX25, LX60, LX100, SX35, SX55, and FX12 are shipping today. Xilinx now has a total of 14 FPGAs in production at 90nm, more than three times the number of its nearest competitor.
