摘要：On receiving a Store instruction from a Release side processor, a sharedmemory transmits a cache invalidation request to an Acquire side processor, increasesthe value of an execution counter, and transmits the count value to the Release sideprocessor asynchronously with the receiving of the Store instruction. The Release side
processor has: a store counter which increases its value when the Store instruction isissued and, when the count value of the execution counter is received, decreases its valueby the count value; and a wait counter which, when the store counter has come to indicate0, sets a value indicating a predetermined time and decreases its value every unit time.The Release side processor issues a Store Fence instruction to request for a guarantee ofcompletion of invalidation of the cache of the Acquire side processor when both thecounters have come to indicate 0.
