Tagged geometric history branch predictor
WebA retired branch normally induces three accesses to the branch predictor tables: read at prediction time, read at retire time and write for the update. We show that in practice, the TAGE predictor accuracy would not be significantly impaired by avoiding a systematic second read of the prediction tables at retire time for correct prediction.
