定義了一種完全基于局部處理器的多處理器系統，討論了系統的實現條件，提出了一
種共享總線結構，建立了處理器域之間基于固定地址窗的信息交換機制，實現了無主多處理器系統。從而解決了高端應用中的設備的冗余備份問題，同時提供了靈活而且任意層次的系統級備份模式，具有最高的處理器安裝密度以及信息處理能力。

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.
