Abstract

A system and method of early branch prediction in a processor to evaluate, typically before a full branch prediction is made, ways in a branch target buffer to determine if any of said ways corresponds to a valid unconditional branch, and upon such determination, to generate a signal to prevent a read of a next sequential chunk.
