1- Suppose that the processor has access to 3 levels of memory. Level 1 contains 1000 words and has an access time of 0.01 us; level 2 contains 10,000 words and has an access time of 0.1 us; level 3 contains 100,000 words and has an access time of 1 µs. Suppose 80% of the memory accesses are found in level 1, 15% of the memory accesses are found in level 2, 5% of the memory accesses are found in level 3, then find the average access time ?
