Question: QUESTION 10 Suppose a computer using direct mapped cache has 2 30 words of main memory, and a cache of 4K blocks, where each cache

QUESTION 10

  1. Suppose a computer using direct mapped cache has 230 words of main memory, and a cache of 4K blocks, where each cache block contains 256 words.

    What is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag, line, and word fields?

    Tag= 10-bit, Line= 8-bit, Word= 12-bit

    Tag= 10-bit, Line= 12-bit, Word= 8-bit

    Tag= 14-bit, Line= 4-bit, Word= 6-bit

    Tag= 13-bit, Line= 5-bit, Word= 6-bit
