摘要： CABAC coefficient decoding may be increased to two bins per clock. Since coefficients comprise most of the bitstream, this improvement almost doubles the CABAC decoding for a low quantization parameter bitstream (with lots of coefficients).
摘要翻译： CABAC系数解码可以每个时钟增加到两个bin。由于系数包括大多数比特流，所以这种改进对于低量化参数比特流（具有大量系数）几乎使CABAC解码加倍。

摘要： A camera input can be used by the computer to support audio spatialization or to improve audio spatialization of an application that already supports it. A computer system may to support audio spatialization, for example, by modifying the relative latency or relative amplitude of the rendered audio packets. If a sound is intended, for example, to be located on the left side of the user, then the audio channel that is rendered on the headset speaker located on the user's left ear may have a somewhat decreased latency and increased amplitude compared to the other audio channel.
摘要翻译：计算机可以使用相机输入来支持音频空间化或改善已经支持它的应用的音频空间化。计算机系统可以支持音频空间化，例如通过修改所渲染的音频分组的相对等待时间或相对幅度。例如，如果声音位于用户的左侧，那么在位于用户左耳上的耳机扬声器扬声器上呈现的音频通道可能会稍微降低等待时间并且与其他音频通道相比增加幅度音频通道。

摘要： In accordance with some embodiments, a fixed function media accelerator may be preempted in the middle of processing one frame of data and still be able to resume operation later without the need to save an internal state. This ability to be preempted, without saving an internal state, may be important for supporting page fault and increasing the responsiveness of fixed function engines. Enabling preemption without the need to save the entire state reduces the complexity of the implementation in some embodiments.
摘要翻译：根据一些实施例，固定功能介质加速器可以在处理一帧数据的中间被抢占，并且仍然能够在稍后恢复操作而不需要保存内部状态。这种在不保存内部状态的情况下被抢占的能力对于支持页面错误并增加固定功能引擎的响应性可能是重要的。在一些实施例中，启用抢占而不需要保存整个状态降低了实现的复杂性。

摘要： 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.

摘要： In general, in one aspect, a decode order for a group of picture (GOP) frame structure for a video stream is modified to include regenerated P frames. The modified decode order includes a regenerated P frame of a P frame decoded prior to a sequence of B frames after last B frame in the sequence of B frames and before next I or P frame. The frames are decoded in modified decode order by a decode engine. The decoded frames are post processed in a display order (only includes regenerated P frames and does not include initial P frames defined in the decode order) by a post processing engine. The post processing engine may ignore the initial P frames or the decode engine may not forward the initial P frames to the post processing engine. The post processed frames may be prepared for presentation by a display engine.
摘要翻译：通常，在一个方面，用于视频流的一组图像（GOP）帧结构的解码顺序被修改为包括再生的P帧。经修改的解码顺序包括在B帧序列中的B帧之后和在下一个I帧或P帧之前的B帧之后的序列之前解码的P帧的再生P帧。帧由解码引擎以修改的解码顺序解码。解码帧以后处理引擎以显示顺序（仅包括再生的P帧，并且不包括以解码顺序定义的初始P帧）进行后处理。后处理引擎可以忽略初始P帧，或者解码引擎可能不将初始P帧转发到后处理引擎。后处理帧可以准备用于由显示引擎呈现。

摘要： In general, in one aspect, a graphics driver receives information related to where eyes of a user watching a video are focused, determine if the user is focusing their attention on a particular location of the video, and generates post processing instructions for pixel macro blocks of decoded video frames. The instructions are based on whether it is determined that the user is focused. The graphics driver is further to determine a focus area associated with the particular location the user is focusing their attention on, determine a peripheral area around the focus area, generate a first set of post processing instructions for pixel macro blocks within the focus area, generate a second set of post processing instructions for pixel macro blocks within the peripheral area, and generate a third set of post processing instructions for pixel macro blocks not within either area.
