Modern cpu chips have one two or even three levels of cache


1. Modern CPU chips have one, two, or even three levels of cache on chip. Why are multiple levels of cache needed?

2. Suppose that a CPU has a level 1 cache and a level 2 cache, with access times of 1 nsec and 2 nsec, respectively. The main memory access time is 10 nsec. If 20% of the ac- cesses are level 1 cache hits and 60% are level 2 cache hits, what is the average access time?
