摘要
介绍RapidIO协议和以MPC8641D处理器及Tsi578交换芯片组成的RapidIO互连系统硬件平台,在此平台上进行基于VxWorks操作系统的RapidIO驱动开发,实现RapidIO的主要功能,如读写、消息传递、门铃事务等,并对RapidIO通信机制进行带宽和时延的测试,验证RapidIO通信的基本功能和性能。
This paper introduces the RapidlO protocol and the hardware platform of RapidlO interconnect system which is composed of MPC8641D and Tsi578 switch chip. On this platform, it designs the RapidlO drive based on VxWorks operating system, carries out the main function of RapidlO, such as read and write, message passing, doorbell transaction and so on, and tests the bandwidth and latency of RapidlO communication mechanism, validates the basic skill and performance of RapidlO communication.
