Make an assumption that your cache is either: Fully associative Direct mapped Two-way set-associative Four-way set-associative determine: the size of the Tag and Word for Associative cache; OR the size of the Tag, Line, and Word for Direct-Mapped Cache ; Or the size of Tag, Set, and Word for K-Way Set-Associative Cache. You may make any assumptions necessary including the number of Words in each block (recommend 2 or 4 or 8)

1. 2-way Set Associative Cache Memory Consider a hypothetical machine with 1K words of cache memory. They are in two-way set associative organization, with cache block size of 128 words, using LRU replacement algorithm. Suppose the cache hit time is 9ns, the time to transfer the first word from main memory to cache is 50ns, while subsequent words require 10ns/word. Consider the following read pattern (in blocks of 128 words, and block id starts from 0): 1 2 3 5...
