In this exercise, we will examine how replacement policies impact miss rate. Assume a 2-way set associative cache with 4 blocks. To solve the problems in this exercise, you may find it helpful to draw a table. Consider the following address sequence: 0, 2, 4, 8, 10, 12, 14, 8, 0. a– Assuming an LRU replacement policy, how many hits does this address sequence exhibit? Please show the status of the cache after each address is accessed. b – Assuming an MRU (most recently used) replacement policy, how many hits does this address sequence exhibit? Please show the status of the cache after each address is accessed.

Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:
