CSCI 620 Homework 2
Due: September 23, 2022
Factors: 35
Do the next issues; present your work:
Drawback A (three Factors)
Think about a 2 MB Four-way set associative cache. Suppose a block is 64 bytes and an
handle consists of 32 bits. If we assume that an handle area is split as
described within the textual content: tag-field, index-field, block-offset, compute the size of
every area for this cache; present your work:
a. tag-field size in bits:
b. index-field size in bits:
c. block-offset size in bits:
A.2 (5 Factors) In computing the reply to this downside:
• assume that the conditional branches are taken 70% of the time, and never taken
30% of the time.
• do the computation for the common frequencies of astar and hmmer (not bzip
and hmmer).
B.2 (6 Factors) Do components a and b. For half b, assume that the cache is an eight-way
set associative cache.
B.eight (6 Factors) Do components a and b. In arising together with your estimates, assume that
the hit occasions are comparatively small and could be ignored.
B.13 (5 Factors) Assume that the content material of the TLB doesn’t change for this
downside.
2.20 (Four Factors) Do half a with the next adjustments: the primary 16 byte block can
be acquired in 60 cycles (not 120); and every extra 16 byte block requires 32
cycles (not 16)..
2.42 (6 Factors) Do components c and d. Compute slowdown as a ratio relative to native
execution. As well as: what’s the geometric imply of the pure and para
virtualization ratios?
