  • Patent number: 7783823
    Abstract: One embodiment includes a system comprising a processor configured to read and write data packets via a data bus to and from at least one additional hardware device. The system also comprises a data buffer configured to store a plurality of consecutive related flits associated with at least one of the data packets in one of a plurality of addressable locations of the data buffer. The system further comprises a pointer memory configured to store a respective pointer associated with each of the plurality of addressable locations of the data buffer.
    Type: Grant
    Filed: July 31, 2007
    Date of Patent: August 24, 2010
    Assignee: Hewlett-Packard Development Company, L.P.

  • Patent number: 6825699
    Abstract: Buffer that includes an input node, an output node, and a three-transistor charge pump circuit is coupled to the input node and the output node. The buffer generates an output signal that is a delayed version of a signal presented at the input node. The three-transistor charge pump includes a first transistor (e.g., a pass transistor) that includes a drain electrode that is coupled to the input node, a gate electrode and a source electrode; a second transistor that includes a drain electrode that is coupled to a first predetermined voltage, a gate electrode coupled to the drain electrode of the second transistor, and a source electrode coupled to the gate electrode of the first transistor; and a capacitive element that includes a first electrode that is coupled to the source electrode of the second transistor and the gate electrode of the first transistor and a second electrode that is coupled to the output node.

  • Patent number: 6715014
    Abstract: A module array includes a lead-in transmission line from a driving source. The lead-in transmission line ends with a series impedance between the lead-in transmission line and a star node. The star node has a terminating impedance between it and a termination voltage. At least two branch transmission lines diverge from the star node. Modules connect to the branch transmission lines in a comb topology.
