摘要
弹载红外图象处理器是一个复杂的实时红外图象处理系统。由于它的计算量很大，实时性很强，单ＣＰＵ已经不可能完成如此繁重的任务。本文分析了弹载红外图象处理器中多ＣＰＵ之间通信的几种方法。在分析几种通信方法的原理和各自的优缺点之后，提出了弹载红外图象处理器中多ＣＰＵ之间通信应采用双口ＲＡＭ作共享存储器的并行通信方法，我们所设计的系统中均采用这种方法。实验证明这种方法的数据信息通信具有很高的灵活性和可靠性，完全满足弹载红外图象处理器中多ＣＰＵ之间通信的要求。
The missile borne infrared image processor is a complex real-time infrared image signal processing system,It is abvious that a single CPU is not able to be employed to take such a great amount of computation tasks because of the stfict real-time requirement of the signal processor several multi-CPUcommu-nicatio n principles and methods has been discribed and a nalysed in this paper,and it is put forward that a multi-CPU parallel communication model with a double-port RAM as the common-shared memory used in the practical missile borne infrared image signal processor.It is verified in tests that the requirenemts of the missile borne infrared image signal processor can be totally satisfied for the high flexibility and reliability shown in the way of the multi-CPU communication.
