Abstract: A method and apparatus for storing and utilizing set prediction information regarding which set of a set-associative memory will be accessed for enhancing performance of the set-associative memory and reducing power consumption. The set prediction information is stored in various locations including a branch target buffer, instruction cache and operand history table to decrease latency for accesses to set-associative instruction and data caches.
