摘　　要：基于对飞行器飞行控制软件的需求(包括功能需求以及性能需求)的分析结果,提出一种基于战星嵌入式实时操作系统的多核分布式飞行控制软件架构,架构共分为5层,从下至上依次为:操作系统层、硬件接口层、框架层、应用层和重用构件层。该架构目前已经应用于多个项目,具有可移植性好、可靠性高、实时性强等特点,能够降低项目研制时间与成本,提高飞行控制软件的可靠性与安全性。Firstly, the functional requirements and performance requirements of fly control software on rockets or missiles are analyzed. Based on the requirements results, multi-core distributed software architecture based on the MARS real-time operating system(RTOS) is presented. The architecture is divided into five layers that are known as RTOS layer, hardware excuse layer, frame layer, application layer, reuse component layer from top to bottom. This architecture is used in a couple of programs, which has good portability, high reliability and can segment in real time. It also can reduce development time and cost, and improve fly control software reliability and security.
