A design scheme of a high-performance, commonly-used processing module is presented.The module selects four high-performance, dual-core CPUs to meet the data-processing and signal-processing requirements through parallel working, adopts three high-speed serial buses to meet the transfer bandwidth requirements, uses switch fabric to construct high-speed interconnect structure of the system with expandability and fault-tolerant/reconfiguration functions.The design of the module is in accordance with VPX (ANSI/VITA 46) standard, which can meet the requirement of the multi-task, real-time processing in the synthesized embedded system.
