摘要
针对现代社会对数据传输速率要求的不断提升,现有的传输方式如PCI总线、PCI Express总线及千兆网等,已经不能满足技术的需求。因此,采用了一种新型的传输方式,利用SRIO总线的高速特性和交换芯片多端口的灵活性,对不同种类的设备节点(DSP、FPGA、PowerPC)进行网状结构的拓扑互联,实现数据高速和灵活传输的目的。主要介绍了在一个拓扑网络内部DSP、FPGA和PowerPC设备节点的SRIO配置方式及网络中全拓扑系统的实现过程,并对该系统进行了速率和正确性测试,为实时数据处理技术提供了必要的技术基础。
With increasing data transfer rate requirement of the modern society,existing transmission modes,such as PCI bus,PCI Express bus,gigabit network,etc.,cannot meet the technical needs.Therefore,a new type of transmission mode is adopted,using the high speed feature of SRIO bus and the switching chip multiport flexibility for mesh interconnection of different types of device nodes（ DSP,FPGA,PowerPC）,in order to realize high-speed flexible data transmission.The paper mainly introduces the SRIO configuration mode of device nodes（ DSP,FPGA,PowerPC） in a topology network and the realization of whole network topology system,gives the test results of the rate and correctness of the system,and provides the necessary technical foundation for real-time data processing technology.
