Q.2.
A computer system has a cache (L1). For a given program with 1 million instructions, L1 cache miss rate
is 20%. Average instruction execution time is 40 ns. For all misses, time to take a block from main memory into the LI
cache is 600ns.
a. Calculate the time to execute this program. Give your result in milliseconds.
b. You need to improve the performance of this system. You replace the cache by a new one that is 2 times faster than the
existing one, but the new cache has smaller capacity, so the miss rate is increased to 25%. Will the new design improve
the performance? Calculate the execution time of the program and prove your answer.
