Inclusive cache
WebAnother advantage of inclusive caches is that the larger cache can use larger cache lines, which reduces the size of the secondary cache tags. (Exclusive caches require both caches to have the same size cache lines, so that cache lines can be swapped on a L1 miss, L2 hit). If the secondary cache is an order of magnitude larger than the primary ... WebThe cache is one of the many mechanisms used to increase the overall performance of the processor and aid in the swift execution of instructions by providing high bandwidth low latency data to the cores. With the additional cores, the proc essor is capable of executing more threads simultaneously.

Multi-level caches can be designed in various ways depending on whether the content of one cache is present in other levels of caches. If all blocks in the higher level cache are also present in the lower level cache, then the lower level cache is said to be inclusive of the higher level cache. If the lower level cache … See more Consider an example of a two level cache hierarchy where L2 can be inclusive, exclusive or NINE of L1. Consider the case when L2 is inclusive of L1.
