摘要： Examples are disclosed that relate to depth-aware late-stage reprojection. One example provides a computing system configured to receive and store image data, receive a depth map for the image data, processing the depth map to obtain a blurred depth map, and based upon motion data, determine a translation to be made to the image data. Further, for each pixel, the computing system is configured to translate an original ray extending from an original virtual camera location to an original frame buffer location to a reprojected ray extending from a translated camera location to a reprojected frame buffer location, determine a location at which the reprojected ray intersects the blurred depth map, and sample a color of a pixel for display based upon a color corresponding to the location at which the reprojected ray intersects the blurred depth map.

摘要： Independently processing planes of display data is provided by a method of outputting a video stream. The method includes retrieving from memory a first plane of display data having a first set of display parameters and post-processing the first plane of display data to adjust the first set of display parameters. The method further includes retrieving from memory a second plane of display data having a second set of display parameters and post-processing the second plane of display data independently of the first plane of display data. The method further includes blending the first plane of display data with the second plane of display data to form blended display data and outputting the blended display data.

摘要： Embodiments include a texture mapping processor incorporating a dynamic level of detail map for use in a graphics processing system. Level of detail values are defined, with 0 being the finest and corresponding to the largest mipmap level. Each bound texture in a graphics object is assigned an identifier. This identifier is used as an index into a minimum-LOD value tracking table that is updated whenever a texel is fetched. A texture processing module controls when the tracking table is initialized and read back, and which identifiers are tracked. The minimum-LOD values in the tracking table are accompanied by a coarse region access mask to associate a minimum LOD value with a specific region of the image or object. A clamping table contains LOD clamp values for each region and a region code that specifies the coarseness of the LOD associated with each region of the texture.

摘要： A hardware-based aperture compression system permits addressing large memory spaces via a limited bus aperture. Streams are assigned dynamic base addresses (BAR) that are maintained in registers on sources and destinations. Requests for addresses lying between BAR and BAR plus the size of the bus aperture are sent with BAR subtracted off by the source and added back by the destination. Requests for addresses outside that range are handled by transmitting a new, adjusted BAR before sending the address request.

摘要： A computer graphics processing system provides efficient migrating of a GPU context as a result of a context switching operation. More specifically, the efficient migrating provides a graphics processing unit with context switch module which accelerates loading and otherwise accessing context data representing a snapshot of the state of the GPU. The snapshot includes its mapping of GPU content of external memory buffers.

摘要： A method and apparatus for graphical processing. A logic core to perform pixel fragment manipulation and processing is instantiated on a single substrate with one or more memory units. The memory units are dynamically segmentable into frame buffer and texture memory. Because the logic core is on the same substrate as the memory units, the bandwidth between the core and the memory is greatly increased.

摘要： Embodiments directed to an autonomous graphics processing unit (GPU) scheduler for a graphics processing system are described. Embodiments include an execution structure for a host CPU and GPU in a computing system that allows the GPU to execute command threads in multiple contexts in a dynamic rather than fixed order based on decisions made by the GPU. This eliminates a significant amount of CPU processing overhead required to schedule GPU command execution order, and allows the GPU to execute commands in an order that is optimized for particular operating conditions. The context list includes parameters that specify task priority and resource requirements for each context. The GPU includes a scheduler component that determines the availability of system resources and directs execution of commands to the appropriate system resources, and in accordance with the priority defined by the context list.
