Display co-processing

摘要

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.

主权项

1. A method comprising:
rendering and transmitting, by an application processor, display data to a display; causing, by a display manager based on a computing device entering a state of low graphical activity, the application processor to write data to control registers of the low-power processor and enter a low-power state; decreasing, by the display based on the computing device entering the state of low graphical activity, a refresh-frequency of visual content; and generating and sending to the display, by a low-power processor based on the computing device entering the state of low graphical activity and based on the data stored in the control registers by the application processor, additional display data to alter at least a portion of visual content presented by the display.
