Question: The average CPI for L1 and L2 cache system with no miss is 1.0. L2 has a hit rate of 80%. L1 has a miss

The average CPI for L1 and L2 cache system with no miss is 1.0. L2 has a hit rate of 80%. L1 has a miss rate of T%. 1 cycle takes 0.25 ns. The miss penalty for L1 is 8 cycles and for L2 is 54 cycles. If the cache average access time is found to be 0.8 ns, evaluate the miss rate of the L1 cache?
