摘要： A cache access control system for dynamically conducting specification of dedicated and common regions and thereby always conducting optimum cache coherency control. In a processor, an L1 cache including an L1 data array and a directory is provided. A plurality of L2 caches are connected to each L1 cache. The L2 caches are connected to a main memory L3. An L2 cache history manager is supplied with L2 cache status information and an L2 cache access request from L2 caches. The L2 cache history manager judges an attribute (a dedicated region or a common region) of each line of L2. On the basis of the attribute, a cache coherency manager conducts coherency control of each L2 cache by using an invalidation type protocol or an update type protocol. The attribute is judged to be the common region, only in the case where a line shared by a plurality of L2 caches in the past is canceled once by the invalidation type protocol and then accessed again.
