摘要:
A method for determining whether to store binary information in a fast way or a slow way of a cache is disclosed. The method includes receiving a block of binary information to be stored in a cache memory having a plurality of ways. The plurality of ways includes a first subset of ways and a second subset of ways, wherein a cache access by a first execution core from one of the first subset of ways has a lower latency time than a cache access from one of the second subset of ways. The method further includes determining, based on a predetermined access latency and one or more parameters associated with the block of binary information, whether to store the block of binary information into one of the first set of ways or one of the second set of ways.
