The Intel 80486 has an on chip, unified cache. It contains 8 kB and has a four-way set-associative organization and a block length of four 32-bit words. The cache is organized into 128 sets. There is a single “line valid bit” and three bits, B0, B1, and B2 (the “LRU” bits), per line. On a cache miss, the 80486 reads a 16-byte line from main memory in a bus memory read burst. Draw a simplified diagram of the cache and show how the different fields of the address are interpreted.
