Abstract

A branch target buffer comprises a partitioned cache memory having for each partition a CAM array holding the least significant bits of a fetch address, a RAM holding the least significant bits of a target address, and comparators for comparing the most significant bits of the fetch and target addresses to control entry of a branch instruction into the buffer.
