What is the AMAT for P1 with the addition of an L2 cache? Is the AMAT better

Question:

What is the AMAT for P1 with the addition of an L2 cache? Is the AMAT better or worse with the L2 cache?

For the next three problems, we will consider the addition of an L2 cache to P1 to presumably make up for its limited L1 cache capacity. Use the L1 cache capacities and hit times from the previous table when solving these problems. The L2 miss rate indicated is its local miss rate. a. b. L2 Size 1 MB 8 MB L2 Miss Rate 95% 68% L2 Hit Time 5.62 ns 23.52 ns
