Compare performance of a Processor with cache vs. without cache. Assume an Ideal processor with 1 cycle memory access, CPI = 1 Processor without cache: Assume main memory access time of 4 cycles Assume 50 % instructions require memory data access Processor with cache: Assume cache access fime of 1 cycle Assume hit rate 0.95 for instructions, 0.80 for data Assume miss penalty (time to read memory into cache and from cache to processor) is 5 cycles > Compare execution times of 1million instructions:
