    Abstract: Systems, apparatuses, and methods for saving power on a bus interface are described. A system includes a host, a device, and a repeater interposed between the host and the device. While the host and device are in a low-power state, the repeater monitors a first bus to determine if the device has woken up. When the repeater detects a remote wake-up event initiated by the device, the repeater generates an interrupt which is sent to the host. The host responds to the interrupt by initiating a resume wake-up event procedure that assumes the device is still asleep. In this way, the host is able to stay in the low-power state longer while also using a wake-up procedure that does not require the host to be aware of the existence of the repeater.

    Abstract: Circuits, methods, and apparatus where a dongle or adapter may provide continuous power in the event of a disconnection of a charging device. One example may provide a dongle having a charge storage circuit. A charging device connected to the dongle may be used to power an accessory also connected to the dongle. Following a disconnection of the charging device, the dongle may use the charger storage circuit to provide power to the accessory for a first duration. After the first duration, a host device also connected to the dongle may provide power to the accessory via the dongle.

    Abstract: Methods and apparatus for dynamically allocating resources to a plurality of controllers are disclosed. In one embodiment, the controllers comprise multiple types of Universal Serial Bus compliant controllers. When a USB-compliant device is detected, one or more determinations are made regarding the detected device such as the supported data transfer speed capabilities. Based on the one or more determinations, the device is directed to an appropriate controller.

    Abstract: 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.

    Abstract: 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.
