Ace cache organization questions in competitive exams, job interviews, and computer organization and architecture course exams. Genuinely understand the implementation and working of caches in modern computers.
In this course, we will begin with an introduction to the memory hierarchy in modern computers. We will see why the computers employ several different types of memories, such as CPU registers, caches, main memory, hard disk, etc. After the introduction, the rest of the course focuses on caches. We will see that cache is a small but extremely fast piece of memory that sits between the fast CPU and slower RAM (main memory). The course is divided into the following nine sections: Introduction, Temporal locality, Performance implications of caches, Spatial locality, Writes in caches, Content addressable memory, Direct mapped caches, Set associative caches, Cache eviction, and hierarchical caches. The sections have several bite-sized lectures, practice problems, detailed animation examples illustrating concepts, and quizzes. Detailed solutions to the practice problems are included in the video and on the last page of the worksheets. Keys and explanations for the quiz questions are also provided. Specifically, the course will answer the following questions in detail.
1. Why do our computers have so many different types of memories?
2. What is a cache?
3. Why is a cache needed?
4. What data should be kept in a cache?
5. What are temporal and spatial locality?
6. How do caches exploit temporal locality?
7. How do caches exploit spatial locality?
