Abstract : This paper describes the conditional branch predictor that the author submitted to the unlimited-size track of the 4th Championship Branch Prediction. The proposed predictor consists of 5 TAGE predictors which we have tuned for better accuracy under huge storage budget. The overall prediction is obtained by combining the 5 TAGE predictions via COLT fusion. One of the 5 TAGE components takes a conventional global path as input. The 4 other TAGE components take as input different sorts of first level histories.
