Abstract: A system and method for authenticating a user of a device includes a user fob configured to transmit a code related to authentication, wherein the device is configured to receive the transmitted code and confirm that the holder of the fob is or is not an authorized user. In an embodiment, the device is configured to detect a user presence before checking for receipt of a transmitted code. In a further embodiment, the device is configured to emit a beacon upon detecting a user presence, prompting the user fob to transmit the code. The beacon medium may be IR (infrared), ultrasound or other low power medium, and similarly, the fob may detect the beacon and/or transmit the code in any suitable medium including IR and ultrasound.

Abstract: Systems and methods for displaying always-on content on a display of a mobile device allow the device to use a low power processor for certain always-on content and to coordinate with the device application processor for the remaining always-on content. In an embodiment, a pixel row-skip pattern is specified by the low power processor based on the display screen's resolution setting as well as ambient light conditions. In a further embodiment, the execution of pixel rendering in keeping with the prescribed pattern is synchronized between the device's low power processor and main application processor.

Abstract: One disclosed method includes communicating with a kernel running on a primary processor, by a second processor, in response to detection of a state change; performing a hardware operation, in response to the state change, using the kernel without waking user space on the primary processor, where the user space remains suspended; and resuming a sleep mode of the primary processor by suspending the kernel after the hardware operation is completed. One example of a hardware operation is modification of display data on a touchscreen display. The method of operation may perform the hardware operation using the kernel without waking hardware drivers other than a hardware driver related to the hardware operation.

Abstract: One disclosed method includes generating a rule set by an application running on a primary processor. The rule set specifies how the application handles events. The rule set is sent from the primary processor to a secondary processor and the primary processor is placed in sleep mode. The secondary processor may then handle at least one event corresponding to the application by executing the rule set while the primary processor is in sleep mode. In one embodiment, handling the event may include substituting for the application by the secondary processor by executing the rule set, and controlling a peripheral hardware device that is peripheral to the primary processor according to the rule set. Handling an event may also include waking the primary processor from sleep mode by the secondary processor and passing control back to the primary processor.

Abstract: One disclosed method includes registering a graphics buffer with a kernel running on a first processor, storing the registered graphics buffer in memory initially without drawing the graphics buffer to a display, and passing the registered graphics buffer to a kernel display driver directly to draw the graphics buffer to the display, in response to a trigger. The method may further include informing a second processor of the registered graphics buffer and receiving the trigger by the kernel as a message from the second processor. The first processor may receive the trigger as a wake command from the second processor while the first processor is in sleep mode. A partial resume of the kernel is then performed while preventing activation of user space on the primary processor, and the graphics buffer is drawn on the display without using an operating system graphics pipeline of the user space.

Abstract: A method performed by an adjunct processor of a device for bringing a primary processor of the device out of a sleep mode includes monitoring a touchscreen of the device for a first continuous gesture. The method also includes sending, by the adjunct processor to the primary processor upon detecting the first continuous gesture, an initial awake command signal to awaken the primary processor from the sleep mode to initiate a primary processor awake sequence. Further, the method includes monitoring the touchscreen for completion of a second continuous gesture to initiate the sending, by the adjunct processor to the primary processor, of a primary awake command signal to indicate to the primary processor to complete the primary processor awake sequence.

Abstract: A method is performed by an adjunct processor of a device for bringing a primary processor of the device out of a sleep mode. The method includes: monitoring for a set of inputs that indicates a likelihood of the primary processor being provided a primary awake command signal to awaken the primary processor from a sleep mode. The method further includes sending, by the adjunct processor to the primary processor upon receiving the set of inputs, an initial awake command signal to awaken the primary processor from the sleep mode.

Abstract: In embodiments of display co-processing, a computing device includes a display, a full-power processor, and a low-power processor that can alter visual content presented by the display without utilizing the full-power processor. The low-power processor can, responsive to a request from the full-power processor, generate additional display data to update display data stored in a frame-buffer of the display. The low-power processor can then transmit the additional display data to the frame-buffer effective to alter at least a portion of the visual content presented by the display. In some embodiments, the additional display data is transmitted via a protocol converter that forwards the display data to the display using a display-specific communication protocol.
