Calculate the access time when there is a cache miss

Assignment Help Computer Engineering
Reference no: EM1333954

A single level cache has following specifications.

Access time = 2.5 ns
Line size = 64 bytes
Hit ratio = 0.95

Main memory uses a block transfer capability, and has first word (4 bytes) access time of 50 ns and access time for following words as 5 ns.

Compute 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.

Will increasing the line size to 128 bytes, and a resulting increase in H (hit ratio) to .97, reduce the average memory access time?
