ABSTRACT:
A hybrid branch predictor is disclosed. The predictor includes prediction aiding information, a plurality of branch predictors to provide a plurality of branch predictions, a plurality of storage elements to hold less than full extent of the branch predictions, but sharing information among said plurality of storage elements enables extraction of said full extent of the prediction. The predictor also includes a selection mechanism to select a prediction from the plurality of branch predictions.
