For the next three problems, we will consider the addition of an $L2$ cache to P$1$ to

presumably make up for its limited L$1$ cache capacity. Use the L$1$ cache capacities and hit

times from the previous table when solving these problems. The $L2$ miss rate indicated is

its local miss rate.

What is the AMAT for P$1$ with the addition of an L$2$ cache? Is the AMAT

better or worse with the $L2$ cache? $(10$ pts$)$

Assuming a base CPI of $1\mathrm{.}0$ without any memory stalls, what is the total CPI

for P$1$ with the addition of an L$2$ cache? $(6$ pts$)$

Which processor is faster, now that P$1$ has an L$2$ cache? If P$1$ is faster, what

miss rate would $P2$ need in its $L1$ cache to match $P1\text{'}$s performance? If $P2$ is

faster, what miss rate would P$1$ need in its L$1$ cache to match P$2\text{'}$s

performance? $(10$ pts$)$
