Consider a computer system with 2 levels of caches L1 and L2. L1 Cache has l-Cache and a D-Cache. The I cache has a miss rate of 17% and the D-Cache has a miss rate of 14.6%. The miss penalty to L2 cache is 13 cycles. L2 cache miss rate is 70.9% and the miss penalty to the main memory is 177 cycles. The frequency of all data operations is 34%. Assuming a processor with no memory stalls has a CPI of 3. What is the CPI with memory stalls? Select one: O a. 33.42 O b. 27.19 O c. 46.76 O d. None of the options O e. 6231894.43 O f. 45.51
