摘要: The crossbar-multi-processor (CMP) architecture is an interconnection of multis using a hierarchy crossbars. It intended to be the base architectural framework that can used experiment with different processors, various directory protocols for communication among and memory keep caches coherent, parallel programming paradigms. Each multi in provides low latency between small (<8) number processors. Communication supported by To support large hierarchical connection crossbars employed. CMP combines advantages snooping cache schemes scalable multiprocessor consistent. shared distributed system. reduce global traffic each also has associative store contains locked data items processor.
