The trade-off between fast branch prediction and good branch prediction is sometimes dealt with by having two branch predictors. The first branch predictor is fast and simple. The second branch predictor, which is slower, more complicated, and with bigger tables, will override a possibly wrong prediction made by the first predictor. Neural Methods for Dynamic Branch Prediction † Eden and Mudge ] but do not change the basic prediction mechanism. Given a generous hardware budget, many of these two-level schemes perform about the same as one another [Eden and Mudge ]. Most two-level predictors cannot consider long history lengths, which be-. Figure 1: One-Level Branch Predictor Dynamic Branch Prediction on the other hand uses information about taken or not taken branches gathered at run-time to predict the outcome of a branch. There are several dynamic branch predictor in use or being researched nowadays.
