Abstract: Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.

Abstract: Techniques are disclosed that involve the processing of audio streams. For instance, a host processing platform may receive a content stream that includes an encoded audio stream. In turn, a graphics engine produces from it a decoded audio stream. This producing may involve the graphics engine performing various operations, such as an entropy decoding operation, an inverse quantization operation, and an inverse discrete cosine transform operation. In embodiments, the content stream may further include an encoded video stream. Thus the graphics engine may produce from it a decoded video stream. This audio and video decoding may be performed in parallel.
