Assume a computer design problem having following parameters: Main memory: 128KB, 4-way Set-Associative mapped cache, Cache size: 1KB, Block size: 8 Bytes. Computer program accesses (in order) memory locations: 137, 138, 169, 170, 1203, 1205. (i) What is the hit ratio? (ii) What are the final cache contents? Assume that the cache is empty at the beginning.
