ABSTRACT:
A branch predictor generates an index to access a branch prediction table storing branch prediction reference data therein. The index is generated in response to a combination of a branch history, a branch instruction address, and a process ID. The process ID is derived from one of multiple processes operating on a multi-processing computer with which the branch predictor is associated.
