Method and apparatus for efficient ordered stores over an interconnection network

摘要

A physically distributed cache memory system includes an interconnection network, first level cache memory slices, and second level cache memory slices. The first level cache memory slices are coupled to the interconnection network to generate tagged ordered store requests. Each tagged ordered store requests has a tag including requester identification and a store sequence token. The second level cache memory slices are coupled to the interconnection network to execute ordered store requests in-order across the physically distributed cache memory system in response to each tag of the tagged ordered store requests.
