Abstract
An apparatus and method for branch prediction are disclosed. The branch predictor has four portions. The first includes a bimodal branch predictor in series with a local branch predictor; the second includes a global branch predictor. The first and second portions are in parallel and operate concurrently, and each provide an output received by the fourth portion. The third portion receives address data and selection data, and also provides output to the fourth portion. The fourth portion receives these outputs, and provides a branch prediction. The branch prediction is a selection of either the output from the first portion or the output from the second portion, based upon selection criteria received from the third portion.
