Question: Assume we build a cache with a 1 ns access time, and RAM for main memory has access time of 6 0 ns . a

Assume we build a cache with a 1 ns access time, and RAM for main memory has access time of 60 ns. a.(5 points) How high of a hit rate do we need to sustain an average total access time of 7 ns? b.(5 points) The CPI of load on HIT is 5, but on MISS is 120. What is the average CPI for load given the hit rate in (a)?
