False Statement 1: Every write hit in WB leads to a data transfer from cache to main memory
In Write Back (WB) cache, when a write operation hits the cache, the data is modified in the cache block but not immediately transferred to the main memory. Instead, a dirty bit associated with the cache block is set to indicate that the data in the cache block is different from the corresponding block in main memory. The modified data is only transferred to the main memory when the cache block is evicted from the cache to make space for a new block. Therefore, a write hit in WB cache does not always lead to a data transfer from cache to main memory.
False Statement 2: A read miss in WB will never lead to eviction of a dirty block from WB
In Write Back (WB) cache, when a read operation misses the cache (i.e., the requested data is not present in the cache), a cache block replacement is performed to fetch the required data from main memory. If the cache block selected for replacement is dirty (i.e., modified), it needs to be written back to the main memory before the new block is fetched. This ensures that the modifications made to the cache block are not lost. Therefore, a read miss in WB cache can lead to eviction of a dirty block from the cache.
True Statement 1: Every write hit in WT leads to a data transfer from cache to main memory
In Write Through (WT) cache, when a write operation hits the cache, the data is immediately transferred to the main memory along with the cache update. This ensures that the main memory always reflects the most up-to-date data. Therefore, every write hit in WT cache leads to a data transfer from cache to main memory.
True Statement 2: Each cache block in WB and WT has a dirty bit
Both Write Back (WB) and Write Through (WT) cache organizations maintain a dirty bit for each cache block. The dirty bit indicates whether the data in the cache block has been modified since it was fetched from the main memory. This information is used during cache block replacement to determine if the block needs to be written back to the main memory before eviction. Therefore, each cache block in WB and WT caches has a dirty bit.
