TAGE是目前已知的最准确的条件分支预测器之一。然而,TAGE并没有完美地利用其输入信息,因为通过使用相同的输入信息用统计校正器补充TAGE,可以获得显著的预测准确性改进。本文提出了一种替代的类TAGE预测器,使得统计校正实际上是多余的。
TAGE is one of the most accurate conditional branch predictors known today. However, TAGE does not exploit its input information perfectly, as it is possible to obtain significant prediction accuracy improvements by complementing TAGE with a statistical corrector using the same input information. This article proposes an alternative TAGE-like predictor making statistical correction practically superfluous.
