Assume that main memory accesses take 60ns while L1 cache has the following features: L1 cache hit time: 0.5ns, L1 cache miss rate: 8%. What is the average memory access time if we only have L1 cache? Now suppose we add an L2 cache with hit time as 5ns. What would the L2 miss rate need to be in order for the average memory access time to be improved compared with L1 cache only?
