Abstract
Some embodiments describe techniques that relate to hybrid graphics display power management. In one embodiment, data corresponding to one or more image frames of a video stream are stored in a local frame buffer. A display device (e.g., an LCD) may then be driven based on the stored data in the local frame buffer or a video stream from a graphics controller. Other embodiments are also described.
Claims30
An apparatus comprising:
- a display switching logic to drive a display device, the display switching logic to comprise:
- a local frame buffer to store data corresponding to one or more image frames of a video stream;
- and
- a controller to determine whether to drive the display device based on:
- the stored data in the local frame buffer or a video stream from a graphics controller.
2 more elements
A method comprising:
- storing data corresponding to one or more image frames of a video stream in a local frame buffer;
- determining whether to drive a display device based on:
- the stored data in the local frame buffer or a video stream from a graphics controller;
- and
- driving the display device.
2 more elements
A computer-readable medium comprising one or more instructions that when executed on a processor configure the processor to:
- store data corresponding to one or more image frames of a video stream in a local frame buffer;
- determine whether to drive a display device based on:
- the stored data in the local frame buffer or a video stream from a graphics controller;
- and
- drive the display device.
2 more elements
A system comprising:
- a memory to store context switching data;
- and
- a display switching logic to drive a display device, the display switching logic to comprise:
- a local frame buffer to store data corresponding to one or more image frames of a video stream;
- and
- a controller to determine whether to drive the display device based on:
- the stored data in the local frame buffer or a video stream from a graphics controller.
