Abstract:
Methods, systems and computer system products to allow audio decryption and decoding to be performed on a graphics engine instead of on a host processor. This may be accomplished without having to modify media application software. A down codec function driver exposes a down codec to a media application, which may then send encrypted and encoded audio data to the down codec function driver. The down codec function driver may then redirect the audio data to a graphics driver. The graphics driver may then pass the audio data to a graphics engine. The graphics engine may then decrypt and decode the audio data. The decrypted and decoded audio data may be returned to the graphics driver, which may then send the decrypted and decoded audio data to the function driver. The function driver may then pass the decrypted and decoded audio data to the down codec for rendering.
Abstract:
Power gating a portion of a graphics processor may be used to improve performance or to achieve a power budget. A processor granularity, such as a slice or subslice, may be gated.
Abstract:
A processor may operate at a first frequency level for a first time interval. The processor automatically may transition to a sleep state from the first frequency level after the first time interval. Then the processor automatically transitions from the sleep state to the first frequency level after a second time interval. As a result the processor may operate at a reduced power consumption and higher performance.

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.
