Assume an instruction cache miss rate for an application is 2% and the data cache miss rate of 4% where load and store are 20% of the instruction set. Assume further that our CPU is running at 1 GHz and has a CPI of 2 without any memory stalls The main memory access time is 50 ns. a. Determine the overall CPI with the indicated misses. b. Suppose we like to add a second level cache with an access time of 10 ns which has an instruction miss rate of .4% and data cache miss of 6%. Determine the overall CPI.
