(A) For each of these references, identify the
binary word address, the tag, and the index
given a direct-mapped cache with 16 one-word
blocks. Also list whether each reference is a hit
or a miss, assuming the cache is initially empty.
(B) For each of these references, identify the
binary word address, the tag, the index, and the
offset given a direct-mapped cache with two-
word blocks and a total size of eight blocks.
Also list if each reference is a hit or a miss,
assuming the cache is initially empty.
(C) You are asked to optimize a cache design
for the given references (i.e. addresses). There
are three direct-mapped cache designs
possible, all with a total of eight words of data:
(i) Cache1 has 1-word blocks,
(ii) Cache2 has 2-word blocks, and
(iii) Cache3 has 4-word blocks.
