3. Direct Mapped Cache Organization

The chapter covers the organization and operation of direct-mapped caches, including cache lines, tag fields, cache hits, and misses. It provides practical examples illustrating how memory addresses map to cache lines and how data is retrieved from memory. The significance of utilizing fast cache memory to reduce execution time by exploiting local reference patterns is emphasized.
