$3$ Cache Performance

Please answer the following questions regarding average memory access time $($AMAT$).(20$ pts $)$

$1.$ If a specific cache design has $\backslash (2\backslash \%\backslash )$ miss rate for a set of benchmarks with a hit latency of $20$ cycles and a miss penalty of $200$ cycles. What is the AMAT for this cache?

$2.$ If another cache design has $\backslash (5\backslash \%\backslash )$ miss rate for the same set of benchmarks with a hit latency of $13$ cycles and a miss penalty of $200$ cycles. What is the AMAT for this cache?

$3.$ Which cache design is better?
