摘要
一种嵌入式计算机系统,硬件以386EX CPI 为核心,支持实时纠错编码和标准的军用总线接口MIL-STD-1553B,软件基于VxWorks实时多任务操作系统,支持基于FLASH的文件系统。对该计算机系统的设计与实现的过程,包括硬件的构成、底层软件设计和应用软件开发调试中的问题进行了说明。
The implementation of an embedded computer system was introduced. The core of the hardware is 386EX CPU. Real time error detect and correction was supported. A standard millitary data bus MIL-STD-1553B was used as external interface. The software was based on VxWorks, a realtime operation system (RTOS). A flash based file system TFFS managed on board software maintenance (OBSM).
