WebThis allows the GEHL predictor to efficiently capture correlation on recent branch outcomes as well as on very old branches. As on perceptron predictors, the pre-diction is computed through the addition of the predictions read on the predictor tables.

WebA GEHL predictor featuring 13 ta-bles, 5 bit entries and 8K entries per table using (6,2000) history length , i.e. a total of 520 Kbits was considered 3. In practice, on the benchmark set, TAGE encounters an average of 2.17 effective writes per misprediction or 9.06 writes per 100 retired conditional branches.

WebNov 1, 1998 · YAGS introduces tags into the PHT that allows it to be reduced without sacrificing key branch outcome information, and shows that YAGS gives better prediction accuracy for the SPEC95 benchmark suite than several leading prediction schemes, for the same cost.
