<p>A multi-prediction branch prediction mechanism predicts each conditional branch at least twice, first during the instruction-fetch phase of the pipeline and then again during the decode phase of the pipeline. The mechanism uses at least two different branch prediction mechanisms, each a separate and independent mechanism from the other. A set of rules are used to resolve those instances as to when the predictions differ. <IMAGE></p>
