    摘要: A system, method and computer program product are provided for texture shading in a hardware graphics processor. Initially, a plurality of texture coordinates is identified. Further, it is determined whether a hardware graphics processor is operating in a texture shader mode. If the hardware graphics processor is operating in the texture shader mode, the texture coordinates are mapped to colors utilizing a plurality of texture shader stages in the hardware graphics processor. If, however, the hardware graphics processor is not operating in the texture shader mode, the texture coordinates are mapped to colors utilizing a conventional graphics application program interface (API) in conjunction with the hardware graphics processor.

    摘要: A system and associated method are provided for processing pixel data in a graphics pipeline. Included is a triangle module coupled to a rasterizer for calculating a plurality of equations using pixel data received from the rasterizer. Also provided is a shader core module coupled to the rasterizer for receiving the pixel data therefrom. The shader core module is further coupled to the triangle module for receiving the equations therefrom. The shader core module functions to execute floating point calculations and generating texture coordinates using the pixel data. Coupled to the shader core module is a texture module. The texture module is capable of looking up texture values using the texture coordinates. Associated therewith is a shader back end module coupled to the texture module and the triangle module. The shader back end module is capable of converting the texture values to an appropriate floating point representation and generating color values using the equations. Still yet, a combiner module is coupled to the shader core module and the shader back end module. Such combiner module combines the color values and the texture values.

    摘要: A system, method and article of manufacture are provided for programmable processing in a computer graphics pipeline. Initially, data is received from a source buffer. Thereafter, programmable operations are performed on the data in order to generate output. The operations are programmable in that a user may utilize instructions from a predetermined instruction set for generating the same. Such output is stored in a register. During operation, the output stored in the register is used in performing the programmable operations on the data.

    摘要: System and method for reserving a memory space for multithreaded processing is described. Memory space within a memory resource is allocated responsive to thread type. Examples of thread types for graphics processing include primitive, vertex and fragment types. Memory space allocated may be of a predetermined size for a thread type. Memory locations within a first memory space may be interleaved with memory locations within a second memory space.
