基于VPX标准的高速处理模块的设计与实现

摘要

为满足高度综合化的发展对嵌入式数字信号处理技术的更高要求,提出一种高性能数据信号处理模块的设计实现方案.模块采用符合VITA 46/VITA 48的VPX标准设计,用多片高性能多核处理器组建处理器阵列来实现超高数据信号处理性能；采用Serial RapidIO、PCI Express、Gigabit Ethernet三种标准高速串行总线来满足不同应用的高速数据通信要求；采用交换开关式互连体系结构设计,支持容错/重构和可扩展性,能够满足嵌入式领域多通道、多任务的应用需求.%Aimed at the development in the embedded signal processing domain,this paper proposes a design of the high-performance processing module.The module selects four high-performance multi-core CPUs parallel working to meet the processing requirements; based on high-speed Serial RapidIO,PCI Express,Gigabit Ethernet agreement to build interconnect network to meet the transfer bandwidth requirements ; uses switch fabric to construct high-speed interconnect structure of the system,applies VPX (AN-SI / VITA 46) standard architecture to meet the versatility and scalability requirements.It may meet the requirement of the multichannel and multi-task signal processing in the next generation avionics.
