Abstract
A set-associative cache memory having a built-in set prediction array is disclosed. The cache memory can be accessed via an effective address having a tag field, a line index field, and a byte field. The cache memory includes a directory, a memory array, a translation lookaside buffer, and a set prediction array. The memory array is associated with the directory such that each tag entry within the directory corresponds to a cache line within the memory array. In response to a cache access by an effective address, the translation lookaside buffer determines whether or not the data associated with the effective address is stored within the memory array. The set prediction array is built-in within the memory array such that an access to a line entry within the set prediction array can be performed in a same access cycle as an access to a cache line within the memory array.
