6. The average memory access time (AMAT) is possibly useful as a figure of merit for different cache systems.

6.1 Find the AMAT for a processor with a 2 ns clock, a miss penalty of 20 clock cycles, a miss ratc of 0.06 misses per instruction, and a cache access time (including hit detection) of 1 clock cycle. Assume that the read and write miss penalties are the same and ignore other write stalls.
