Logic circuitry provides a fast resolution of conditional branch instructions in a high-performance superscalar processor. The logic circuitry facilities early (fast) resolution of a subset of conditional branches located within the first position of the primary instruction buffer within the processor enabling the overall branch processing logic to bypass history table-based prediction logic for such branches without crossing the cycle boundary. Thus, penalties associated with possible mispredictions for this subset of conditional branches are avoided.
