综合化技术的发展对嵌入式通用处理模块的设计提出了更高的要求。提出一种高性能通用处理模块的设计实现方案, 模块采用多片双核处理器阵列同时具备高性能的数据和信号处理能力; 采用高速串行总线来构建满足不同应用的高速数据通信链路; 采用交换开关式互连结构支持可扩展性和多级容错/重构功能;采用符合VITA 46规范的VPX标准设计, 满足综合化嵌入式系统多任务实时处理的应用需求。

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.
