Method and system for display output stutter

摘要

Apparatus and methods for reducing power consumption of a data transfer interface in a computer system are disclosed. In one embodiment, a method for reducing power consumption of a data transfer interface between a first device and a second device, includes, identifying a free interval between a first data and a second data, disabling the data transfer interface during the free interval, enabling the data transfer interface at the end of the free interval, and transmitting the second data. The method may also include a step of notifying the second device that the data transfer interface is being temporarily disabled. Another embodiment, for example, includes the transfer of display data (or video frames) over an interface, such as, a DisplayPort interface, between a graphics controller device and a timing controller device in a computer system.

主权项

1. A method of reducing power consumption for transferring data frames of a video stream over a data transfer interface between a first device and a second device, the method comprising:
determining, by the second device, whether (a) the video stream is completed or terminated or (b) the data transfer interface is disabled after a notification; notifying the second device over the data transfer interface that the data transfer interface will be disabled temporarily; disabling the data transfer interface upon completion or termination of a first frame of the video stream for an interval between the first frame and a subsequent second frame; in response to the second device determining that the data transfer interface is disabled after the notification, enabling the data transfer interface at the end of the interval; and transmitting the second frame.
