一种双余度车载核心处理机的设计与实现

为适应车载电子系统综合化发展趋势,提高国内车载电子系统综合化水平,根据实际应用需求,设计了一种主从式冗余架构的车载核心处理机。该系统以可靠性好的CPCI总线为基础,采用综合化、模块化、层次化的系统结构设计方法,实现了能够进行冗余功能模块主从切换的综合化车载数据处理中心,为搭建车载综合化计算平台提供有力保障。

Design and Implementation of a Dual Redundancy Vehicle Core Processor

In order to adapt the integrating tendency of armored vehicle electronic system and enhance the integration level of China＇s armored vehicle electronic system, we design an armored vehicle core processor with redundancy structure and Master-Slave Mode based on the practical needs. The system takes CPCI bus with good reliability as the basis, and adopts integrating, modular, and hierarchical system design method, implementing an integrated armored vehicle data processing center that can conduct master-slave switching of redundancy function module, so as to ensure the good performance of integrated armored vehicle electronic system.
