A computer system has a L1 cache.

a) L1 cache access time is 6 ns and hit ratio is H=0.80. Calculate the execution time of a program with 1000000 instructions and an average instruction execution time 20 ns.

b) Suppose the cache design is changed such that H is increased to 0.90, but access time is also increased to 12 ns. Which cache design would you choose?
