cache access time=10ns
main memory access time=200ns
cache hit ratio=0.9
Average access time=hit ratio*cache access time+(1-hit ratio)*(cache access time+main memory access time)
=>0.9*10+(1-0.9)*(10*200)
=>9+(0.1)*(2000)
=>9+200
=>209
so average access time =209

6. Memory Access Time [15 points] 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...
