Arithmatica IP selected by Xilinx for Virtex-4 XtremeDSP(TM) Slice

Xilinx’s SX55 Sets New DSP Performance Threshold with CellMath IP  

MENLO PARK, Calif. – Mar. 15 , 2005 – Arithmatica, Inc., the silicon math company, today announced that Xilinx, Inc. has deployed Arithmatica’s CellMath™ IP in its Virtex-4 SX55 FPGA – the world's fastest and lowest-power FPGA for digital signal processing (DSP) applications. The SX55 device delivers 256 billion multiply-and-accumulate per second (MAC/s) processing performance, nearly three times more than any other FPGA. The SX55, with 512 XtremeDSP™ Slices, is the highest-performance member of the SX family.  All of the available Virtex-4™ FPGA family members include some number of XtremeDSP Slices and each has benefited from the joint design collaboration effort between Xilinx and Arithmatica.

According to Brent Przybus, Sr. Manager of product marketing for the Advanced Products Group at Xilinx, “The power and versatility of CellMath IP made it an ideal choice for Virtex-4 signal processing solutions.  Many of our customers are trying to solve very complex signal processing challenges such as those associated with base stations and software defined radio (SDR) and these require the highest performance at the lowest per function power consumption.”

With up to 512 XtremeDSP Slices operating at 500MHz, designers now can implement hundreds of IF-to-baseband down-conversion channels, 128X chip-rate processing for 3G spread spectrum systems, and high-definition H.264 and MPEG-4 encode/decode algorithms, while using just 10 percent of the power consumption of previous FPGA DSP implementations.

Dave Burow, Chairman of the Board at Arithmatica said, “With Virtex-4, Xilinx allows designers to meet the demanding performance requirements of next-generation communications and media processing systems while retaining all of the development cost, flexibility and time to market advantages of FPGA, We’re pleased that Xilinx chose Arithmatica as a technology and development partner.”
