摘要： One embodiment of the present invention sets forth a method for pre-computing Z-values using an IGPU and, subsequently, conveying these Z-values to a DGPU. The graphics driver partitions the display into rectangular M-by-N tiles of pixels. For each tile, the graphics driver generates a quad geometry that encompasses the corresponding pixels. For each image frame, the graphics driver configures the IGPU to generate and down-sample a Z-buffer, creating a coarse Z-texture that contains a Z-value for each tile. The graphics driver transfers the coarse Z-texture to the system memory and configures the DGPU to apply the coarse Z-texture to the quad geometries, thereby generating a coarse Z-buffer in which the M-by-N pixels included in each tile are assigned the Z-value for the particular tile. Among other things, this technique enables the IGPU to pre-compute Z-values for the DGPU without straining the system memory bandwidth or defeating the Z-buffer compression techniques used by the DGPU.

摘要： One embodiment of the present invention sets forth a method for dynamically load balancing rendering operations across an IGPU and a DGPU. For each frame, the graphics driver configures the IGPU to pre-compute Z-values for a portion of the display surface and to write feedback data to the system memory indicating the time that the IGPU used to process the frame. The graphics driver then configures the DGPU to use the pre-computed Z-values while rendering to the complete display surface and to write feedback data to the system memory indicating the time that the DGPU used to process the frame. The graphics driver uses the feedback data from the IGPU and DGPU in conjunction with the percentage of the display surface that the IGPU Z-rendered for the frame to scale the portion of the display surface that the IGPU Z-renders for one or more subsequent frames. In this fashion, overall processing within the graphics pipeline is optimized across the IGPU and DGPU.

摘要： One embodiment of the present invention sets forth a technique that enables a user to reverse through video content based on scene transitions. By employing a graphics processing unit to compute one or more frame-to-frame correlation coefficients that measure the consistency of sequential images and a central processing unit to analyze the one or more correlation coefficients, a list of scene transitions may be generated in real-time. The list of scene transitions forms the basis for a content-based reverse user control within the playback application. The content-based reverse user control enables a more natural mechanism for reversing through video content, providing the user with a superior overall viewing experience.

摘要： A system and method uses the capabilities of a geometry shader unit within the multi-threaded graphics processor to offload data compression computations from a central processing unit (CPU), reduce the memory needed to store image data, and reduce the bandwidth needed to transfer image data between graphics processors and between a graphics processor and a system memory. The multi-threaded graphics processor is also configured to compress data for use in memory paging and when data is relocated to lie within an accessible memory aperture. The data is losslessly compressed using a geometry shading program to produce variable length compressed data.

摘要： Split-frame post-processing techniques are used in a programmable video post processing engine. A frame of video data is divided into a processing region and a control region that contain either different portions of the frame or copies of a portion of the frame. Post-processing operations are performed for the processing region but not for the control region. The processing and control regions are then displayed simultaneously on the same display device (e.g., side by side), facilitating visual comparisons of images with and without post-processing.

摘要： Multichip graphics processing subsystems include at least three distinct graphics devices (e.g., expansion cards) coupled to a high-speed bus (e.g., a PCI Express bus) and operable in a distributed rendering mode. One of the graphics devices provides pixel data to a display device, and at least one of the other graphics devices transfers the pixel data it generates to another of the devices via the bus to be displayed. Where the high-speed bus provides data transfer lanes, allocation of lanes among the graphics devices can be optimized.
