20120000705 | CIRCUITRY FOR ACTIVE CABLE - Circuits, methods, and apparatus that allow signals that are compliant with multiple standards to share a common connector on an electronic device. An exemplary embodiment of the present invention provides a connector that provides signals compatible with a legacy standard in one mode and a newer standard in another mode. | 01-05-2012 |
20120005496 | POWER DISTRIBUTION INSIDE CABLE - Circuits, methods, and apparatus that provide for the powering of active components in connector inserts at each end of a cable may in various ways. For example, where a host is coupled to a device that is not self-powered, the host may provide power for circuitry at each end of the cable. In various embodiments of the present invention, the device may request higher voltage from the host, such that more power can be delivered. In these cases, the device may regulate the voltage received from the host to a lower voltage, and then provide the lower voltage to circuitry at one or both ends of the cable. Where the host is connected to a device that is self-powered, the host and the self-powered device may power their respective connector insert circuits. | 01-05-2012 |

20120278645 | CLOCK SYNCHRONIZATION ACROSS AN INTERFACE WITH AN INTERMITTENT CLOCK SIGNAL - The disclosed embodiments provide a system that facilitates synchronization between a first component and a second component connected to the first component via an interface in a computer system. During an active state of the interface, the system uses a local time base in the second component to generate a local clock signal that tracks a host clock signal from the first component. Next, during an inactive state of the interface, the system uses the local time base to maintain the local clock signal at the second component. Finally, during a subsequent active state of the interface after the inactive state, the system adjusts the local clock signal to remove clock drift between the local clock signal and the host clock signal. | 11-01-2012 |

20140092107 | SHARING A GRAPHICS-PROCESSING-UNIT DISPLAY PORT - An electronic device selectively couples a head with links in a graphics processing unit to a currently selected display port in a pair of display ports. During operation, control logic in the electronic device monitors a pair of configuration signals from the pair of display ports, where the pair of configuration signals correspond to physical connections to the pair of display ports. Then, the control logic determines a selection control signal based on the monitored pair of configuration signals, a policy setting and a default display port, where the selection control signal specifies the currently selected display port. Moreover, the control logic provides the selection control signal to a multiplexer in the electronic device. Next, the multiplexer selectively couples the head with the links in the graphics processing unit to the currently selected display port based on the selection control signal. | 04-03-2014 |
