Improving Branch Prediction Accuracy in Embedded Processors in the Presence of Context Switches

Abstract

Embedded processors like Intel’s XScale use dynamic branch prediction to improve performance. Due to the presence of context switches, the accuracy of these predictors is reduced because they end up storing prediction histories for several processes. This paper shows that the loss in accuracy can be significant and depends on predictor type and size… (More)
