4. What observations can be made about the correlation between the miss rate and the cache size and type? (4 pts)

Question

Answer

j.  
 
 For cache sizes below 256, the direct-mapped cache exhibits a lower miss rate.

Answer

d.  The cache miss rate decreases with increasing cache size.

Answer

c.  Beyond size 128, the Miss rate remains the same for all organizations, because all the program’s memory references are below 128.

Answer

e.  For cache sizes larger than 256, the miss rate fluctuates, as certain memory references go beyond the cache capacity.

Answer

h.  The best cache performance, in terms of miss rate, is achieved with the 2-way set-associative cache organization.

Answer

g.  For cache sizes larger than 128, the miss rate decreases across all cache organizations, as all memory references fall within the cache capacity.

Answer

f.  For all cache sizes below 256, the direct-mapped cache exhibits a higher miss rate compared to set-associative caches.

Answer

b.  The cache miss rate increases with increasing cache size.

Answer

i.  The best cache performance, in terms of miss rate, is achieved with the 4-way set-associative cache organization.

Answer

a.  For cache sizes above 128, the 4-way set-associative cache exhibits a higher miss rate.
