Question

We are given a list of 64-bit memory address
references, given as word addresses.
Ox03, Oxb4, Ox2b, 0x02, Oxbf, Ox58, Oxbe, OxOe,
Oxb5, Ox2c, Oxba, Oxfd
(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.
