Abstract: This paper introduces an implementation of a high performance, high reliable and reconfigurable computer. The core of the hardware is MPC8240 CPU. Real-time error detect and correction are supported. A standard millitary data bus MIL-STD-1553B is used as external interface. The software is based on VxWorks, a real-time operation system(RTOS). A flash based file system TFFS manages on board software maintenance(OBSM).

摘要： 设计并实现一种应用于空间飞行器的嵌入式、高性能、高可靠、可重构计算机的设计与实现。硬件以MPC8240 CPU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。介绍硬件的构成、底层软件设计和应用软件开发调试中的问题。
