The conditional jumps can be predicted with 60% accuracy, and the loop jumps can be predicted with 90% accuracy. The penalty for guessing wrong is four cycles. There is no penalty for unconditional jumps or correct guesses. What is the efficiency of the pipeline on this machine? 2. A cache system has a 95% hit ratio, an access time of 100nsec on a cache hit and an access time of 800nsec on a cache miss. What is the effective access time?
