A processor includes at least one processing core. The processing core includes a memory cache, a store queue, and a post-retirement store queue. The processing core retires a store in the store queue and conveys the store to the memory cache and the post-retirement store queue, in response to retiring the store. In one embodiment, the store queue and/or the post-retirement store queue is a first-in, first-out queue. In a further embodiment, to convey the store to the memory cache, the processing core obtains exclusive access to a portion of the memory cache targeted by the store. The processing core buffers the store in a coalescing buffer and merges with the store, one or more additional stores and/or loads targeted to the portion of the memory cache targeted by the store prior to writing the store to the memory cache. |
