摘　　要：本文提出一种基于IEEE-1394b协议的光总线系统实现方案。并以DSP和IEEE1394b协议芯片为基础,利用CPLD进行时序配合,完成了光总线系统总线扩展电路的硬件电路和程序设计,使光总线系统可以兼容采用多种通用通信协议的设备。在基于总线扩展电路搭建的光总线系统中,从PC端的总线系统网络拓扑图可以看出所设计的总线扩展电路可以满足应用的需求。This paper shows a means of optical bus implementation using IEEE-1394b. Based on DSP chip and IEEE1394b protocol chips with appropriate timing provided by CPLD, the bus extension circuit design and program design of optical bus is accomplished, which can facilitate the compatibility between optical bus system and the devices adopted different general communication protocols. In optical bus system which adopted the bus extension circuit, from the network topology diagram of optical bus on PC, it can be concluded that the bus extension circuit meets the needs of practical applications.
