System and method for accelerating ownership within a directory-based memory system

摘要

The current invention provides a system and method for managing data stored within a main storage device such as a main memory. In one embodiment, multiple requesters are coupled to the main storage device to store copies of ones of the data signals. A directory is coupled to the main storage device to store directory signals that describe the most recent copy of each the data signals. Another storage device is coupled to the directory to store a subset of the directory signals that describes a predetermined subset of the data signals. This subset of directory signals can be used to access any of the predetermined subset of the data signals in an accelerated manner.
