Consider a computer system with 2 levels of caches L1 and L2. L1 Cache has I-Cache and a D-Cache. The I cache has a miss rate of 10.3% and the D-Cache has a miss rate of 11.5%. The miss penalty to L2 cache is 26 cycles. L2 cache miss rate is 53% and the miss penalty to the main memory is 123 cycles.The frequency of all data operations is 35.5%. Assuming a processor with no memory stalls has a CPI of 1. What is the CPI with memory stalls? Select one: O a. 14.12 b. 18.95 + c. 20.88 d. 11.45 O e. 2662428.15 f. None of the options
