Abstract:
For a memory access at a processor, only a subset (less than all) of the ways of a cache associated with a memory address is prepared for access. The subset of ways is selected based on stored information indicating, for each memory access, which corresponding way of the cache was accessed. The subset of ways is selected and preparation of the subset of ways is initiated prior to the final determination as to which individual cache way in the subset is to be accessed.
