Abstract

A system and method of logically partitioning shared memory structures between computer domains is disclosed. In one embodiment, each domain is assigned a unique address space identifier. The unique address space identifier preferably has tag extension and index extension bits. This permits the tag and index bits of a conventional local domain address to be extended with tag extension and index extension bits. Data entries in the shared memory structure may be accessed using an extended index value. Hits may be determined using an extended tag value.
