Abstract: this paper, we examine two new branch predictor optimizations. Firstisanewbranch prediction optimization called Squash False Path (Squash-FP) that attempts to know a branch's guarding predicate value as it is being fetched, and, if it is false, then the branch is predicted as not-taken. The goal of this predictor is to correctly predict the region branches that are on the false path as not-taken (Update)
