In order to improve its prediction accuracy, many branch predictors have been investigated in the past few decades. In this paper, the Bimode++ branch predictor is proposed as an enhanced version of Bimode branch predictor. The Bimode++ branch predictor is unique by using the feature of extremely biased branches. Our experimental results using benchmarks from SpecFP, SpecINT, multi-media and server area show that Bimode++ branch predictor gives better prediction accuracy than Bimode branch predictor.}, title = {極端な偏りを利用するBimode++分岐予測器の提案}, year = {2005} }
