Consider a single-level cache with an access time of 5 ns, a block size of 128 bytes and a hit ratio H = 0.95. Main memory uses a block transfer capability that CSC 295 Homework 2 Page 1 of 3 has a first-word (8 bytes) access time of 100 ns and an access time of 10 ns for each word thereafter. A. What is the access time when there is a cache miss? Assume that the cache waits until the line has been fetched from main memory and re- executes for a hit. B. Suppose that increasing the block size to 256 bytes increases H to 0.97 Does this reduce the average memory access time
