摘要
定义了一种完全基于局部处理器的多处理器系统,讨论了系统的实现条件,提出了一种共享总线结构,建立了处理器域之间基于固定地址窗的信息交换机制,实现了无主多处理器系统。从而解决了高端应用中的设备的冗余备份问题,同时提供了灵活而且任意层次的系统级备份模式,具有最高的处理器安装密度以及信息处理能力。
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.
