Direct Mapped vs Fully Associative Caches:
Direct Mapped Caches:
- Direct mapped caches have a one-to-one mapping between memory blocks and cache blocks.
- Each memory block can only be placed in a specific cache block determined by a specific index.
- Direct mapped caches do not need a cache block replacement policy as each memory block can only be placed in one specific cache block.
Fully Associative Caches:
- Fully associative caches allow any memory block to be placed in any cache block.
- The full address is stored alongside the data block in a fully associative cache, allowing for more flexible mapping.
- Fully associative caches require a more complex hardware structure to search for data blocks.
Explanation of False Statement:
- Option 'D' states that direct mapped caches may produce more misses if programs refer to memory words that occupy a single tag value, which is false.
- In a direct mapped cache, each memory block is mapped to a specific cache block based on the index.
- If a program references memory words that occupy a single tag value in a direct mapped cache, it will not necessarily result in more misses compared to a fully associative cache.
- The number of cache misses in a direct mapped cache is determined by the cache block size and the memory access pattern, not solely by the fact that memory words occupy a single tag value.
