CACHE MEMORY, METHOD FOR RETRIEVING CACHE MEMORY, INFORMATION PROCESSOR, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve the problem of increasing an access time because of subsequently starting MSHR retrieval in an MSHR in the case that a cache memory using a technology of a non-blocking cache performs tag retrieval in a tag memory to make a cache mistake when a processor makes a memory access request.SOLUTION: The cache memory includes a tag memory, an MSHR (Miss information/Status Holding Register), tag memory retrieval means, MSHR retrieval means, and cache control means for operating the tag retrieval means and the MSHR retrieval means in parallel in response to a request for data from a processor.
