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 10.6% and the D-Cache has a miss rate of 10.5%. The miss penalty to L2 cache is 21 cycles. L2 cache miss rate is 69% and the miss penalty to the main memory is 152 cycles.The frequency of all data operations is 35.2%.
