Download Computer Organization: CPU Cache and the Memory Hierarchy

What you would learn in Computer Organization: CPU Cache and the Memory Hierarchy course?

Ace questions about cache organization in exam competitions, job interviews, and computer examinations for architecture and organizational courses. Know the proper implementation and operation of caches on modern computers.

In this class, we'll begin with an introduction to the memory hierarchy of modern computers. We will learn why computers use various kinds of memory, like caches, CPU registers, primary memory, hard disk, and more. Following an introduction to the course, the second part of the class focuses on caches. It will be apparent that caches are a tiny but high-speed bit of memory, which is between the CPU's speed and the slower RAM (main memory). The course is split into nine sections: Introduction, Temporal Locality and the performance impact of caches, Spatial location Writing in caches content addressable memory Direct-mapped caches set associative caches Cache eviction, as well as Hierarchical caches. The sections include short lectures and problems to practice elaborate animations that illustrate concepts and questions. The detailed solutions to the exercises are available in the video and on the final webpage of worksheets. The keys and explanations for questions on the quiz are also included. Mainly you will be taught to be able to answer the following questions in depth.

1. What does the reason computers come with numerous types of memory?

2. How do you define a cache?

3. What is the reason a cache is needed?

4. What kind of information should be saved in the cache?

5. What are spatial and temporal localization?

6. How do caches exploit temporal locality?

7. How do caches exploit spatial locality?

8. What is the LRU's classic policy on the replacement of caches?

9. How do you use cache block? What are they?

10. What is associativity in caches?

11. Is it a cache that is entirely associated?

12. What is a direct-mapped cache?

13. What is an associative set cache?

14. How do you determine if an address in memory will be a miss or hit inside the cache?

15. How does the address breakdown work to access the data stored in direct, associative, fully associative set-associative, or mapped caches?

16. How can I modify the data stored in caches?

17. How do you define a write-through cache?

18. Is a cache for writeback ever a thing?

19. How dirty are the bits that are used in write-back caches?

20. Can other algorithms for evicting caches other than LRU be used?

21. How do caches are organized in a hierarchical structure in modern computers?
