The Intel80486 has on-chip, unified cache. It contains 8Kbytes 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,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. Show the details for the different fields of the address.
