    Abstract: A processor is described that includes a plurality of processing cores. The processor includes an interconnection network coupled to each of said processing cores. The processor includes snoop filter logic circuitry coupled to the interconnection network and associated with coherence plane logic circuitry of the processor. The snoop filter logic circuitry contains circuitry to hold information that identifies not only which of the processing cores are caching specific cache lines that are cached by the processing cores, but also, where in respective caches of the processing cores the cache lines are cached.

    Abstract: Method, apparatus, and systems employing dictionary-based high-bandwidth lossless compression. A pair of dictionaries having entries that are synchronized and encoded to support compression and decompression operations are implemented via logic at a compressor and decompressor. The compressor/decompressor logic operatives in a cooperative manner, including implementing the same dictionary update schemes, resulting in the data in the respective dictionaries being synchronized. The dictionaries are also configured with replaceable entries, and replacement policies are implemented based on matching bytes of data within sets of data being transferred over the link. Various schemes are disclosed for entry replacement, as well as a delayed dictionary update technique. The techniques support line-speed compression and decompression using parallel operations resulting in substantially no latency overhead.
