摘　　要：应国防系统的安全要求,军用计算机的中央处理器逐步采用国产系列CPU来取代国外的产品。结合国产化工程实践需要介绍了一种新型的基于龙芯2F+1A的四余度火控计算机系统的设计思路与方法。详述了多路计算机系统的工作原理,以及基于国产中标麒麟操作余度管理模块的设计。经实验证明该软硬件系统能有效地提高安全性和可靠性,并有良好的实时性和实用性。As the safety-demand of national-defense, the military-computer gradually uses loongson-CPU to re- place overseas-CPU. A new method of fourfold-redundancy fire-control computer system based on domestic Loongson2F ＋ LoongsonlA and its design architecture are introduces. The working principle of multiple com- puter system and the design of redundancy management module based on Neokylin-Linux OS are described in detail. This fourfold-redundancy system can improve security and reliability effectively, and has good instanta- neity and practicability.
