APPARATUS FOR MINIMIZING CACHE STATE CONFLICT IN CACHE COHERENCY MEMORY SYSTEM AND METHOD USING THE SAME

摘要

The present invention relates to a computer-readable recording medium recording a program for realizing the above method and cache collision avoidance device and method in a cache identity maintain memory system, for storing reference information by the nodes inside the interface in a consistent repeater by having the status buffer, see the directory reference when working state buffer by first reducing unnecessary directory references, which can significantly reduce the shared resource conflicts node internal interface and protocol engine maintains the cache identity to prevent cache conflicts in a memory system device and its method and the method to provide a computer readable recording medium recording a program for realizing the protocol engine comprising: a first step of observing the references directory node to be processed by the internal interface unit operation; A second step of the protocol engine determines that the reference writing operation is still open; Wherein if the determination result of Step 2, the reference work pending write, a third step of recording the address to the buffer status; And wherein if the determination result of Step 2, the reference letter operation end state, and a fourth step of removing the corresponding address written in the buffer status, or the like yiyongdoem cache memory system keep identity.
