Two-level adaptive branch prediction
WebTwo-level adaptive branch prediction. Most predictors based on 2-level adaptive branch prediction [Yeh & Patt ’91] Branch outcomes shifted into history register, 1=taken, 0=not taken. History bits and address bits combine to index a pattern history table (PHT) of 2-bit saturating counters. Prediction is high bit of counter Webcompare the Two-Level Adaptive branch predictors to the several popular schemes available in the literature. We show that the average prediction accuracy for Two- Level …
