ABSTRACT:
A method of conditional branching in a pipelined processor. The method comprising the steps of (A) prefetching a branch target address in response to encountering a branch instruction, in prediction of taking a branch, and (B) evaluating between (i) taking the branch and (ii) not taking the branch substantially contemporaneously with prefetching the branch target address.
