WebIn a sectored cache, only one tag needs to be maintained per sector along with a state vector to record the states of the constituent cache blocks (e.g., valid/occupied and dirty). Figure 1 shows a 512-byte sector composed of eight 64-byte cache blocks, four of which are occupied. Two of the occupied blocks are dirty (marked “D”). The WebIn a sectored cache, a cache line is divided into several subblocks. Each subblock is a basic coherence unit. In this way partial block invalidation can be done on the cache lines in order to eliminate false sharing on invalidate-based multiprocessors. Sectored caches often include a facility, called bounteous transfers, to supply extra subblocks after transferring …
