In the research and implement of the multiprocessor system, we have developed a smp like structure which two cpus share a memory, and a cool backup system for the fault-tolerant . this system can meet the requirement of reliability 在多处理器系统体系结构的研究实现上,我们采用了双cpu共享内存的类smp结构,同时进行了系统冷备份冗余的容错设计,保证星载多处理器实时系统的可靠性。
According actual situations, a system design pattern called “ double cpu share memory ” is adopted for such a kind of electro-hydraulic proportional controller . so in the third part, the concrete realization is presented to show the efficiency of the system design pattern, in the middle of which it emphatically give out the design of the hardware driving model 针对怎样实现汽车起重机电液比例控制系统核心控制器问题,即系统的设计问题,本文从整体上研究和比较了多种方案,最终选择了双处理器共享内存的体系结构模式,并且从硬件和软件上完成了核心控制器的详细设计。
