Abstract
A method for supporting a plurality of requests for access to a data cache memory ('cache') is disclosed. The method comprises accessing a first set of requests to access the cache, wherein the cache comprises a plurality of blocks. Further, responsive to the first set of requests to access the cache, the method comprises accessing a tag memory that maintains a plurality of copies of tags for each entry in the cache and identifying tags that correspond to individual requests of the first set. The method also comprises performing arbitration in a same clock cycle as the accessing and identifying of tags, wherein the arbitration comprises: (a) identifying a second set of requests to access the cache from the first set, wherein the second set accesses a same block within the cache; and (b) selecting each request from the second set to receive data from the same block.
