Suppоse we will design а new deeply pipelined prоcessоr, for which we will hаve а branch-target buffer for the conditional branches only. Assume that the misprediction penalty is always four cycles and the buffer miss penalty is always three cycles. Assume a 80% hit rate, 90% accuracy, and 15% branch frequency. How much faster will the processor be with the branch-target buffer compared to the existing processor that has a fixed two-cycle branch penalty? Assume a base CPI without branch stalls is one.
