Abstract
A branch resolution logic for an in-order processor is provided which scans the stages of processor pipeline to determine the oldest branch instruction having sufficient condition codes for resolution. The stages are scanned in order from the latter stages to the earlier stages, which allows quick and simple branch resolution. Therefore, because branches are resolved as soon as the necessary condition codes are generated in a specific stage, branch mispredict penalties are minimized.
