One more thing to keep in … Web“A MultiLevel cache hierarchy has the inclusion property(ML1) if the contents of a cache at level i-tl, C;+l, is a superset of the contents of all its children caches, Ci, at level i.” This definition implies that the write-through policy must be used for lower level caches.

If the lower level cache is inclusive of the higher level cache and it is a miss in the lower level cache, then the higher level cache need not be searched. This implies a shorter miss latency for an inclusive cache compared to exclusive and NINE. richards bay to joburgWebchies simplify cache coherence and are therefore widely used in CMPs [Casazza 2009]. However, inclusive caches have limited performance because of the inclusion property. All blocks stored in higher-level caches also have to be in the inclusive LLC.
