To meet the needs of real-time image processing of space applications,a master-slave parallel computer system based on MPP techniques is designed in this paper. The communications method through shared memory and interlock synchronization mechanisms between the master and the slave are introduced.According to the principles of real time,reliability and high accuracy,a memory organization of storing programs and data in different areas is used in the system.%根据航天实时图象处理的需求，本文设计了一种基于MPP技术的主从式并行计算机系统，主要介绍主从机通过共享数据存储器的通信方式和互斥工作方式。遵从实时性、可靠性、高精度原则，该系统采用了程序和数据分开存储的组织结构。
