Assuming an Instruction cache miss rate for a program is 2%. and a Data cache miss rate is 5%. If a processor has a CPI of 2 without any memory stalls, and the miss penalty is cycles for all misses, Assume that 30% of the instructions are load & stores, 50% of the instructions are ALUs and 20%of the instructions are controls. What is actual CPI with the possible cache misses? Assume that we have perfect data and instruction cache (no cache misses), what is the performance speed up of the CPU with the ideal perfect cache vs. the CPU with actual cache. What if the processor is faster, but memory system is not. Suppose we speed up the CPI from 2 to 1 without changing the clock rate. What is the CPI of the system with cache misses? What is the performance speed up of the CPU with the ideal perfect cache vs. the CPU with actual cache? What is your observation on the effect of the memory on the system performance
