Find out whether a certain cache is inclusive or exclusive by looking at the contents of it.
For the same 60 word fully associative cache with 30-word blocks, say the LRU replacement algorithm is used, and the LRU is always kept in index 0. And say you access the following 3 words, in the given order: 100, 120, 105 a) On the second access (the access of word 120), in which index will the block containing 120 be placed?
In this chapter, you will learn about the four cache replacement policies that have been discussed.
