摘　　要：介绍了1394b总线网络系统和1394b逻辑设计架构,阐述了基于RapidIO架构的双路1394总线控制器的硬件平台。在此平台上进行基于VxWorks操作系统的1394驱动开发和RapidIO驱动开发,并搭建1394b总线网路测试平台。验证了板卡上两路1394b总线控制器的基本通信功能,实现了板卡内部芯片间的高速互联,以及根节点和叶节点在不同通道上、在100 Mbit/s和400 Mbit/s速率模式下的总线网路通信。The 1394b bus network systems, I394b logic design architecture and hardware platform of dual 1394b bus controller based on RapidlO architecture are introduced. On the platform, the 1394b drive and Ra- pidIO drive based on VxWorks operating system are designed, 1394b network test platform is built. Finally, the fundamental functions of the two channels 1394b bus controller are verified. The system interconnection among chips is implemented, as well as computer communications between the root node and the leaf node under the mode at the speed of 100 Mbit/s and 400 Mbit/s.
