Design and Implementation of Crosspoint Switch Module Based on High Speed Serial Bus

Crosspoint switch is the key of parallel data and signals processing technique of next generation avionics. It switches and transfers high- speed digital signals between data processing modules and signal processing modules in parallel processing system. We analyzed the trend and requirements of parallel processing technique of next generation avionics, and introduced the research on crosspoint switch technique and the design of crosspoint switch module. Crosspoint switch module implemented M21131, the crosspoint switch fabric, to build interconnect fabric, which supports any data rate from DC to 3.2 Gbps, can be re- configured online and re-build connection channel between modules when the former one encounters failure. Crosspoint switch module can meet the requirements of parallel processing technology of next generation avionics which needs high- bandwidth, high- reliability and low- delay.
