Jimmy S. Wong has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7983270
    Abstract: Various example embodiments are disclosed. According to an example embodiment, a network device may include a memory management unit. The memory management unit may be configured to populate a count field based on a number of equal cost paths for each Internet Protocol (IP) route for a packet, randomly choose one of the equal cost paths for the packet, and send the packet out of the network device, the packet including route information for the chosen equal cost path.
    Type: Grant

  • Patent number: 7626985
    Abstract: A method of replicating multicast datagrams in a network device is disclosed. The method includes the steps of determining by a memory management unit whether a scheduled outgoing datagram stored in a main memory is a multicast (MC) packet. When the scheduled outgoing datagram type is the MC datagram, the method also includes performing a lookup of a replicate count table to determine a copy count value and writing the copy count value to a copy count register, awaiting a ready signal from an egress port of the network switch and sending the outgoing datagram to the egress port from the main memory along with the copy count value. The method also includes changing the copy count value in the copy count register, modifying a VLAN identifier of the outgoing datagram if necessary based on the copy count value and forwarding the outgoing datagram from the egress port.

  • Patent number: 5377122
    Abstract: A logic compiler wherein verification of a generated circuit model is performed automatically by comparing the operation of the circuit model with that of a corresponding mathematical behavior model. A novel user interface and circuit model generation means enables the user to obtain, in real time, performance specifications on the circuit selected by the user as well as incurring other benefits.

  • Patent number: 4760475
    Abstract: A system and method are described for aligning a set of tracks which have been recorded simultaneously on a magnetic medium by a multichannel transducer mounted in a rotating scanner, with transducing channels of a corresponding multichannel transducer for reproduction. A scan identifier signal is recorded simultaneously by a rotating multichannel transducer at a predetermined location along each track. Means are provided for reproducing and summing simultaneously accessed scan identifier signals during consecutive scans of the multichannel transducer over the medium. The relative position of the recorded medium to the rotating multichannel transducer is changed in a direction across the length of the tracks. That relative position in which the largest amplitude of the summed scan identifier signals is obtained corresponds to the desired alignment with the set of tracks.
