PROBLEM 1
Consider a 2 level cache with access time of 5 ns and 80 ns respectively. If hit rate are 95% and 75% respectively and memory access time is 250 ns, what is average access time?
PROBLEM 2
Calculate the effective address time if average page fault service time of 20 millisec and a memory access time of 80ns. Let us assume the probability of a page fault 10%
