Consider a computer with a processor running at 2 GHz and three levels of cache memory. That is, L1, L2, and L3. Their respective hit times are 2 clock cycles, 15 clock cycles, and 35 clock cycles. Assume main memory has a latency of 100 clock cycles. Some program running on this computer has relatively good locality. This program results in the following cache hit rates: L1 hit rate = 95%, L2 hit rate = 90%, L3 hit rate = 85%. Using this information calculate the average memory access time for this program running on this computer.
