摘要
提出了一种基于双处理器的弹载计算机的设计方法,采用主处理器、协处理器的系统架构,主处理器负责系统管理,协处理器负责数据的采集、转换,两个处理器之间通过IDMA接口进行通讯,详细介绍了处理器、复位、模拟量和离散量设等部分的设计方法。经过验证,表明该设计方法具备工程上的可行性。
This paper introduces a design method of missile-borne computer based on double processes. Computer’s structure of this design method is master-slave mode, master process used to manage system resource, slave process used to collect and convert the signal of sensor. IDMA port is used for communication of master process and slave process. The designs of process、reset、analog signal and discrete signal are presented particularly. Proven results indicate this method having good effect for engineering design.
