  • Control method and circuitry of receiver
    Patent number: 11950016
    Abstract: The present invention provides a control method of a receiver. The control method includes the steps of: when the receiver enters a sleep/standby mode, continually detecting an auxiliary signal from an auxiliary channel to generate a detection result; and if the detection result indicates that the auxiliary signal has a preamble or a specific pattern, generating a wake-up control signal to wake up the receiver before successfully receiving the auxiliary signal having a wake-up command.

  • USB port for employing a plurality of selectable data transmission priority rules
    Patent number: 7996586
    Abstract: A USB port transmitter includes a plurality of arbiters, each employing a distinct priority rule to select one USB transmission from among multiple scheduled USB transmissions based on their types. A selector selects one of the arbiters to select the one USB transmission from among the multiple scheduled USB transmissions. A programmable storage element controls the selector to select the one arbiter. In one embodiment, at least a first arbiter prioritizes header/data packets higher than link commands, and at least a second arbiter prioritizes link commands higher than header/data packets. In one embodiment, at least one arbiter prioritizes flow control and power management link commands higher than header/data packets. In one embodiment, at least a first of the arbiters prioritizes USB LGO_Ux link commands higher than USB LAU/LXU link commands, and at least a second arbiter prioritizes USB LAU/LXU link commands higher than USB LGO_Ux link commands.
