EMU8086 - MICROPROCESSOR EMULATOR

d. The Intel 80486 has an on-chip, unified cache. It contains 8 Kbytes and has a four-way set-associativeorganization and a block length of four 32-bit words. The cache is organized into 128 sets. There is a single "linevalid bit" and three bits, B0, B1, and B2 (the "LRU" bits), per line. On a cache miss, the 80486 reads a 16-byte linefrom main memory in a bus memory read burst. Draw a simplified diagram of the cache and show how thedifferent fields of the address are interpreted. (4 marks)e. Co
