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

Question

Accepted Answer

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

Accepted Answer

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

Accepted Answer

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

Accepted Answer

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

Answer

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

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

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

Answer

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