Suppose we have a deeply pipelined processor, for which we implement a 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 90% hit rate, 80% accuracy, and 10% branch frequency. how much faster is the processor with the branchtarget buffer versus a processor that has a fixed two-cycle branch penalty? assume a base clock cycle per instruction (cpi) without branch stalls of 1.
