Chapter 6, Problem 26E

a)

Explanation of Solution

Price competitive memory hierarchy:

• To develop a price competitive memory hierarchy the system would require a cache that is cheaper.
• The choice of recommendation would be direct mapped or non-associative cache.
• The price is lowered by ignoring the levels of cache. Higher the hierarchy there will be increase in the cost...

b)

Explanation of Solution

Features that is required for the best performance in a memory hierarchy:

• A machine that contains two level caches is required to achieve the better performance.
• Utilizing caches of larger size will be not a good choice because caches are helpful in obtaining higher hit ratio but after a certain period of time there will not be a great change in the hit ratio...
