Question: Suppose that a computer system's cache memory has an access time of 3 nanoseconds and main memory has an access time of 106 nanoseconds. Suppose

Suppose that a computer system's cache memory has an access time of 3 nanoseconds and main memory has an access time of 106 nanoseconds. Suppose that on average, 91% of memory accesses from the CPU are found in the cache and so only incur the cache access time while 9% of the memory accesses incur both the cache access time and because of the cache miss also the memory access time. What is the average memory access for the CPU? Suppose that a level two cache is added between main memory the this cache with a hit rate of 99% and a hit time of 24 nanoseconds. What is the average memory access time for the system with this new cache?
