  • Pseudo least recently used replacement/allocation scheme in request agent affinitive set-associative snoop filter
    Patent number: 8433856
    Abstract: The storage locations of a snoop filter are segregated into a number of groups, and some groups are associated with some processors in a system. When new data enter a cache line of a processor, one of the storage locations associated with the processor is selected for further operations.
    Type: Grant
    Filed: September 14, 2009
    Date of Patent: April 30, 2013
    Assignee: Intel Corporation
    Inventors: Kai Cheng, David C. Lee, John A. Urbanski

  • Microprocessor point-to-point communication
    Patent number: 5634043
    Abstract: A computer system having at least a first microprocessor for processing information and a first memory coupled to the first microprocessor via a first point-to-point interface. The first point-to-point interface provides communication of signals between the first microprocessor and the first memory irrespective of the phase of the signals received by either the first microprocessor or the first memory. The first point-to-point interface includes a first point-to-point circuit in the microprocessor for receiving the signals from the first memory. The first point-to-point circuit and the microprocessor comprise a single integrated circuit in some implemented embodiments, providing ease of construction and design of systems having a variety of topologies.
