Abstract: This paper divides the software into several thread and schedules the priority according to the scheduling and data-flow of guidance and control system. The real-time multithread software of guidance and control system is implemented on the DSP/BIOS operation system. It is proved that this kind of design method can decrease the complexity of software design, and meet the need of real-time, reliability and efficiency of guidance and control system.

Key words: guidance and control, real-time multithread, DSP/BIOS operation system

摘要： 根据制导控制系统的工作时序和数据流图，对其软件进行多线程划分和任务优先级安排，并在DSP/BIOS操作系统支持下实现制导控制系统的实时多线程软件设计。采用实时多线程的软件设计方式，有效降低了软件设计的复杂度，满足了制导控制系统对实时性、可靠性和运行效率的要求。
