一種基于共享總線的冗余容錯(cuò)多處理器系統(tǒng)

定義了一種完全基于局部處理器的多處理器系統(tǒng)，討論了系統(tǒng)的實(shí)現(xiàn)條件，提出了一
種共享總線結(jié)構(gòu)，建立了處理器域之間基于固定地址窗的信息交換機(jī)制，實(shí)現(xiàn)了無(wú)主多處理器系統(tǒng)。從而解決了高端應(yīng)用中的設(shè)備的冗余備份問(wèn)題，同時(shí)提供了靈活而且任意層次的系統(tǒng)級(jí)備份模式，具有最高的處理器安裝密度以及信息處理能力。
關(guān)鍵詞：多處理器，無(wú)主的，共用總線，非透明橋
Abstract：A kind of multiprocessor system completely based on local processor is defined，the conditions how to realize the system are discussed，corresponding architecture which shared bus is put forward, data exchange mechanism based on fixed address window between processor domains is established，and finally the multiprocessor system without host processor is realized. The problem on the device redundancy in the high-end application is thoroughly solved, it supplies us with a redundancy mode which have flexible and any layer in system-level, with a highest assemble density on processor-card and computing ability of data.
Keyword：Multiprocessor，without host，Shared bus，Non-transparent bridge
