Memory Access Time Consider a MIPS processor that includes a cache, a main memory, and a hard drive. Access times of cache memory, main memory, and hard drive are 5 ns, 200 ns, and 1000 ns, respectively. Assume that cache memory is divided into instruction cache and data cache. Assume that data cache has a 90% hit rate. Assume that main memory has a 98% hit rate and hard drive is perfect (it has a 100% hit rate). Use the following formula for average access time calculations: AMST = tcache + MRcache (tMM + MRMM + tV M) (a) What is the average memory access time (b) How many clock cycle per instruction (CPI) on average are needed for load and store word instructions
