6. Associative and Multi-level Caches

The chapter discusses cache memory and how its organization affects performance, particularly focusing on associative and multi-level caches. It highlights the differences between direct-mapped, fully associative, and set-associative caching strategies, explaining their respective strengths and weaknesses in terms of cache miss rates. Furthermore, the chapter describes the importance of a block replacement policy for effective cache management.
