摘要： Video filtering using a programmable graphics processor is described. The programmable graphics processor may be programmed to complete a plurality of video filtering operations in a single pass through a fragment-processing pipeline within the programmable graphics processor. Video filtering functions such as deinterlacing, chroma up-sampling, scaling, and deblocking may be performed by the fragment-processing pipeline. The fragment-processing pipeline may be programmed to perform motion adaptive deinterlacing, wherein a spatially variant filter determines, on a pixel basis, whether a “bob”, a “blend”, or a “weave” operation should be used to process an interlaced image.

摘要： Methods, apparatus and systems for the display, on a remote node, of a three-dimensional (3D) image rendered on a host system in a first image format are described. In general, the 3D image is transformed into a second image format that is compressed (i.e., uses fewer data bits per pixel) relative to the first image format, (optionally) scaled to a screen size of remote node, and subsequently transferred to remote node for display. In instances, the transformation of the image from the first image format to the second image format and the optional scaling of the image to the screen size of remote node may be done in a graphics processing unit (GPU) on the host system. As an example, the first image format may be an RGB-based format, such as RGBA (32-bits per pixel) or standard RGB (24-bits per pixel) and the second image format may be a YUV-based format, such as YV12 (12-bits per pixel).

摘要： A system and method for adjusting pictures minimizes the impact on graphics processing performance of a discrete processor. A hybrid system configuration includes the discrete processor and an integrated processor, where the discrete processor typically consumes more power and provides greater processing performance compared with the integrated processor. A picture is produced by a video or graphics engine of a discrete processor within a hybrid system. Each picture is then transferred to a back buffer in the host processing memory. The picture is analyzed to produce picture analysis results that are used to generate adjustment settings. The back buffer is swapped to become the front buffer and the adjustment settings are applied to the picture by an integrated processor to display an adjusted picture. The adjustment may be used in conjunction with power saving techniques to maintain the image quality when display backlighting is reduced.

摘要： A system is presented that is configured to reduce power consumption when performing processing tasks. The system includes a first processing entity capable of performing a set of operations, and a second processing entity configured to consume less power than the first processing entity and capable of performing a subset of operations that is part of the set of operations. During system operation, the second processing entity is configured to perform the subset of operations instead of the first processing entity.
