摘要： An apparatus and method for converting color data from one color space to another color space. A driver determines that a set of shader program instructions perform a color conversion function and the set of shader program instructions are replaced with either a single shader program instruction or a flag is set within an existing shader program instruction to specify that output color data is represented in a nonlinear color format. The output color data is converted to the nonlinear color format prior to being stored in a frame buffer. Nonlinear color data read from the frame buffer is converted to a linear color format prior to shading, blending, or raster operations.

摘要： Systems and methods for dynamically canceling texture fetches may improve texture mapping performance. A shader program compiler inserts condition code writes and condition code comparison operations for shader program instructions that contribute to a texture read instruction and do not need to be executed if certain conditions are met. During execution of the shader program, the inserted condition codes are used to compute a dynamic writemask that indicates if the texture data resulting from the texture read is unnecessary. The dynamic writemask is used to cancel unnecessary texture fetches during execution of the shader program.

摘要： Hybrid sampling of pixels of an image involves generating shading values at multiple shading sample locations and generating depth values at multiple depth sample locations, with the number of depth sample locations exceeding the number of shading sample locations. Each shading sample location is associated with one or more of the depth sample locations. Generation and filtering of hybrid sampled pixel data can be done within a graphics processing system, transparent to an application that provides image data.

摘要： A method for synchronizing divergent samples in a programmable graphics processing unit is described. In one embodiment, the method includes the steps of determining that a divergence has occurred and detecting that a first sample of a group of samples has encountered a first synch token. The method also includes the steps of determining whether each of the other samples of the group has encountered a synch token and determining whether the synch token encountered by each of the other samples of the group is the first synch token.

摘要： A fragment program may configure a fragment processor to compute several output positions and associated data for a fragment, effectively scattering the fragment. Each output position may be independent of a position computed for the fragment during rasterization of a primitive. Each output position may be computed based on a point light source position to compute a shadow map corresponding to the point light source. A raster operation unit writes processed fragment data to each output position. Furthermore, the fragment program may configure the fragment processor to compute per-output position parameters for the fragment such as stencil and alpha values.

摘要： A system and method are provided for using information from at least one depth layer and for collecting information about at least one additional depth layer utilizing a graphics pipeline. Initially, constraining depth layers are provided which, in turn, define a plurality of depth constraints. Next, a plurality of tests is performed involving the constraining depth layers for collecting information about at least one additional depth layer. The information relating to the at least one depth layer may then be used to improve processing in the graphics pipeline. By the foregoing multiple tests, information relating to a plurality of depth layers may be collected during each of a plurality of rendering passes. Initially, information relating to the constraining depth layers and associated depth constraints is provided in the aforementioned manner. Thereafter, information relating to at least one additional depth layer is collected during additional rendering passes using multiple tests on each rendering pass. Once collected, such information relating to the constraining depth layers and the information relating to the at least one additional depth layer may be used to further improve processing in the graphics pipeline.

摘要： Circuits, methods, and apparatus that provide for partial texture load instructions. Instead of one instruction that may take several shader passes to complete, several instructions are issued, where each instruction is an instruction to retrieve a part or portion of a texture. While each instruction is performed, the other shader circuits can perform other instructions, thus increasing the utilization of the shader circuits when large textures are read from memory. Since several shader passes may be required to read a texture, if a particular instruction needs the texture, one exemplary embodiment reorders instructions such that other instructions are performed before the particular instruction that needs the texture.
