ABSTRACT:
A system and method for distributed cache. Cache tag storage and cache data storage are maintained in separate pipeline stages. Cache tag storage is operated by a data producer. Cache data storage is operated by a data consumer. Cache hits and misses are determined by the data producer prior to any operations being performed by the processor. In the event of a cache miss, produced data is sent to the processor to be processed. In the event of a cache hit, the cache address of the corresponding previously processed data is sent to the data consumer so that the corresponding processed data unit can be retrieved from cache data storage.
