摘　　要：采用一种新的总线桥网络连接方法,实现了由一个总线桥将两个CPU以及多个数字设备连接在一起的功能。重点研究了总线桥的整体结构设计及内部逻辑功能,并对其进行了详细分析及仿真验证。结果表明总线桥能够正确完成双CPU与公共设备之间的通信,提高了系统电路的工作速度和性能,很好地解决了多CPU与公共电路模块之间的通信问题。A connection bridge is designed in this paper. The connection bridge designed in the paper connects two CPU system and three others digital circuitry components together and make the CPU connected with three digital circuitry directly as a part of the CPU system. The architecture and logic functions of the connection bridge are analyzed in detail and simulated. The simulation results demonstrate that the connection bridge can not only supply the connection of two CPU and three common components, but also increase the running speed and system performance.
