Display data and video data are stored within a graphics processing unit to reduce power consumed by the computing device during video playback. Storing display data and video data within the GPU reduces power consumption, because bus transaction activity is reduced and the need to read data from a larger, common main memory is avoided.

Power savings in a computing device during video playback

Video conversion using a 3D graphics pipeline of a graphical processing unit (GPU) is disclosed. A plurality of video data formatted in a first video format is accessed from a memory unit. Moreover, the plurality of video data is converted from the first video format to a second video format using a 3D graphics pipeline of the GPU. The plurality of video data formatted in the second video format is sent to the memory unit. The 3D graphics pipeline applies a filtering technique. In an embodiment, the filtering technique is an interpolation technique.

A method of rendering 3-D graphical image data suitable for use in interactive 3-D applications is provided, which reduces the amount of time required to perform the rendering. This is achieved by dynamically adjusting the resolution of the image depending upon the type of operation being performed. 3-D operations are performed at a reduced resolution, while 2-D operations (including display) are performed at full resolution. A method of dynamically enhancing/reducing resolution for image depth information (z-buffer data) is also provided.
