ECP平台倒机单元的设计实现

Design of Self-regulated Unit in ECP Platform

ECP平台是一套通用的嵌入式插件平台,采用CPCI总线架构,可以使不同功能板卡在平台内部自由搭配组合,最大化的利用系统资源。倒机单元位于整个平台的中心位置,可以根据系统内A机和B机各自的运行状态给出倒机结果,决定哪台机器为当前系统主机。采用逻辑门器件完成了倒机单元设计,具有较高的可靠性和稳定性。

ECP platform is a set of embedded platform with CPCI bus architecture,and it can fulfill the free combination of boards with different functions in the platform and share maximally the system resources.The self-regulated unit is located at the center of the platform to give the result according to the operating state of A and B machines in the system.The result indicates which machine is the host of the current system.The paper introduces to complete the design of the self-regulated unit by using a logic gate device with the high reliability and stability.
