基于CPCI总线的IEEE1394接口模块设计与应用

摘要

IEEE1394 bus is named "Fire wire"t it is an industrial standard high-speed serial bus with the excellence of reliability and high transmission and expansibility. By the TI' s OHCI Lynx chip TSB82AA2 and PHY chip TSB81BA3, the paper introduce a design and application of IEEE1394 interface module based on the CPCI Bus, extended two 1394 ports for the embedded computer system. The module is applied during the command and control system of tank for digital video gathering and supervising, the practice proved it' s steady and reliability.%IEEE1394总线又称之为“火线”,是一种工业标准高速串行总线,具有可靠性好、传输速率高、扩展性强的优点；采用TI公司的链路层控制芯片TSB82AA2和物理层接口芯片TSB81 BA3,设计了一种基于CPCI总线的IEEE1394接口模块,在嵌入式计算机中扩展了2路1394总线接口,该模块在车载指控计算机系统中得到应用,实现了图像采集和视频监控,实际应用表明模块能够在恶劣环境下可靠稳定工作.
