Q9) Assume miss rate of an instruction cache is 2% and miss rate of data cache is 4%. If a processor has CPI of 2 without any memory stalls and miss penalty is 100 cycles for all misses, determine how much faster a processor would run with a perfect cache that never missed. Assume frequency of all loads and stores is 36%.
