Predictor Parameter Variations

In this section, the effect of varying the parameters involved in the design of the branch predictor is studied. The parameters were optimized sequentially and the following subsections report them in that order. The studied parameters include the number of history buffers (n), path history length (p), the number of bits of each target address registered in the history buffer (b), the hashing function, and the structure of the target buffer.
