Question: a . Assume the cache is 5 1 2 bytes, direct - mapped, with 1 6 - byte cache blocks. What is the miss rate?

.

Assume the cache is

512

bytes, direct

-

mapped, with

16 -

byte cache blocks. What is the miss rate? b

.

What is the miss rate if we double the cache size to

1024

bytes?

.

Now assume the cache is

512

bytes, two

-

way set associative with

16 -

byte cache blocks. Furthermore, assume that if a cache miss occurs and the set into which the incoming block is to be brought in is full, the cache block that was accessed the furthest in the past is replaced.

(

This is called the Least Recently Used, or LRU, replacement policy.

)

What is the miss rate?

.

For the cache in part c

,

will a larger cache size help to reduce the miss rate? Why or why not?

a . Assume the cache is 5 1 2 bytes, direct -
