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 在多處理器系統(tǒng)體系結(jié)構(gòu)的研究實(shí)現(xiàn)上,我們采用了雙cpu共享內(nèi)存的類smp結(jié)構(gòu),同時(shí)進(jìn)行了系統(tǒng)冷備份冗余的容錯設(shè)計(jì),保證星載多處理器實(shí)時(shí)系統(tǒng)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 針對怎樣實(shí)現(xiàn)汽車起重機(jī)電液比例控制系統(tǒng)核心控制器問題,即系統(tǒng)的設(shè)計(jì)問題,本文從整體上研究和比較了多種方案,最終選擇了雙處理器共享內(nèi)存的體系結(jié)構(gòu)模式,并且從硬件和軟件上完成了核心控制器的詳細(xì)設(shè)計(jì)。
