Question: Consider a system with a main memory access time of 5 0 ns supported by an L 1 cache having a 5 ns access time

Consider a system with a main memory access time of 50ns supported by an L1 cache having a 5 ns access time and a hit rate of 90% and an L2 cache having a 10 ns access time and a hit rate of 80%.
What is the average memory access time for a look aside cache?
What is the average memory access time for a look through cache?
