Abstract
A computing system includes a processing node having one or more processors and a cache subsystem, and a region-based probe filter directory having a first and second entry, the first entry containing information of a region of a memory, the second entry containing information of a line in the region of the memory, data stored in the region being cached in the cache subsystem. Various other methods and systems are also disclosed.
Claims20
A device comprising:
- a probe filter directory having a first and second entry, the first entry containing information of a first region of a memory, the second entry containing information of a line in the first region of the memory.
A system comprising:
- a processing node including one or more processors and a cache subsystem;
- a region-based probe filter directory having a first and second entry, wherein the first entry includes a tag field pointing to a region of a memory, data stored in the region is cached in the cache subsystem, and the second entry includes state information of a line in the region of the memory.
A method comprising:
- constructing a first entry in a probe filter directory to track a first region of a memory;
- and
- constructing a second entry in the probe filter directory to track a line in the first region of the memory.
Dependencies are inferred from the claim text.
