第4题

Assume the miss rate of an instruction cache is 2% and the miss rate of the data cache is 5%. If a processor has a CPI of 1.5 without any memory stalls and the miss penalty is 50 cycles for all misses, determine how much faster a processor would run with a perfect cache that never missed. Assume the frequency of all loads and stores is 36%. the speed with a perfect cache that never missed / the speed with a cache that will miss=______(number only, keeping 4 significant digits)
