Explain how a 32-bit byte memory address should be divided into
Tag/Index/Offset fields for each of the cache configurations below.
Note: 1KB = 210 bytes. You must explain how many bits to assign to
each field and the ordering of the three fields. You get at most
50% of the credit if you give the length of each field without an
explanation.

Assume there are three small caches, each consisting of four one-word blocks. One cache is fully associative, a second is two-way set-associative, and the third is direct mapped. Find the number of misses for each cache organization given the following sequence of block addresses: 2, 4, 2, 7, 0, and 8. Assume a LRU (least recently used) scheme is used to choose which block to replace.
