摘　　要：为了处理器与总线频率的匹配,实现处理器间的高速通信,提出了一种基于Vx Works嵌入式操作系统的Rapid IO总线驱动的设计方案。Rapid IO硬件平台以MPC8548作为端点处理器,Tsi578芯片作为交换器件。软件部分首先对Rapid IO本地设备进行初始化;然后对Rapid IO网络进行枚举与配置;最后完成消息传递。实际应用表明,该系统实现了Rapi IO总线驱动的高速通信需求,达到了设计要求。In order to match the processor frequency and the bus frequency, realize high-speed communication between the processors,the design of the Rapid IO bus driver based on Vx Works embedded operating system is designed in this paper.Rapid IO hardware platform adopts MPC8548 as the endpoint and Tsi578 chip as switching device.The software parts initialized to Rapid IO local device firstly, then enu-merated and configuration for Rapid IO network, finally completed the messaging pass.The application show that this system has realized the Rapi IO bus driver high-speed communication requirements, and achieves the design requirement.
