hit ratio of H 0.95. Main memory uses a block transfer capability that has a firstword
(4 bytes) access time of 50 ns and an access time of 5 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 then re-executes for a hit.
b. Suppose that increasing the line size to 128 bytes increases the H to 0.97. Does this
reduce the average memory access time?
