Abstract

Disclosed is a method for maintaining a directory of high level cache, multiple lower-level caches, and cache inclusion, where addresses present in low level caches are also present in high-level cache. The method consists of a conventional directory for high-level cache and a directory for each low-level cache in which tags are not addresses, but indexes into a high-level directory.
