Suppose you wanted to add a cache to the basic cpu architecture. recall that to design a cache you must decided: • cache size (how much memory the cache has. this can be given in blocks) • block size (what size chunks is used to divide main memory? ) • mapping function • replacement policy operating systems concepts page 1 cs/se 4348.003 reflection 01 fall 2019 • write policy • number of levels (assume one level for this assignment) decide what each of these should be, and explain why you chose what you did. do not make cache size too large. remember cache is expensive. you must justify the size of the chosen cache. you may assume that the main memory is 16 kb. assume that there is some operating system on the machine that will be managing multiple programs. this means cache would be used for multiple tasks
