Computer Architecture:

A system has 256 words of main memory, 64 words of cache, and a block size of 8 words. The following words are access in this order: 0x2a, 0x84, 0xc8, 0x43, 0x2c, 0x22, 0x4d, 0xc9, 0x98, 0x06, 0x14, 0xfa, 0x08, 0x63, 0x2b, 0x20. (Word Address) The cache starts empty. (write result in excel show tag and age)

- Using a 4-way set associative (4 blocks in a set) cache with LRU replacement

- Use direct mapping
