| 摘 要： | 为了满足新的信号处理平台使用RapidIO技术来进行重构的要求,实现DSP芯片在信号处理板之间和机箱之间的动态连接配置,提出了一种基于RapidIO的网络交换板卡的设计和实现方式。板卡使用TSI578交换芯片构成RapidIO交换机,来实现信号处理板和网络交换板之间的RapidIO数据包路由交换;使用千兆以太网和光纤来实现机箱间的互连;使用FPGA芯片来实现RapidIO和千兆以太网、光纤数据之间的协议转换。应用结果表明,利用该网络交换板能够很好的实现DSP芯片在板卡间与机箱间的互连重构。

| Abstract: | In order to satisfy the requirements of reconstructing the new signal processing platform using RapidIO technology,and implement the DSP’s dynamic connection configure between the signal processing boards and the crates,a design and implementation of network switching board based on RapidIO is proposed.The board used TSI578 switching chips to construct the RapidIO Switches;and used Gigabit Ethernet and optical fiber to implement the crates’ connection;and used FPGA chip to implement the protocol conversion between the Ethernet,optical fiber and RapidIO.The results of application indicated that it was good to realize the connection’s reconstruction of DSP between boards and crates using this network switching board. |
