Silvus Communication Systems rolls soft PHY core for Wi-Fi

San Francisco -- A startup spun out of UCLA is developing soft cores for next-generation wireless systems ranging from Wi-Fi to software-defined and cognitive radios.

The first commercial product from Silvus Communication Systems Inc. (Los Angeles) aims to give a leg up to developers of next-generation Wi-Fi chip sets and systems. The company has developed the VHDL software for a physical-layer chip that exceeds the requirements of the upcoming IEEE 802.11n standard. The code, running on a Xilinx Virtex-II FPGA, supports a 4 x 4 matrix for multiple input, multiple output (MIMO), the key antenna technology behind the pending .11n standard.
