    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 pixel 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.

    摘要: A fragment program may configure a fragment shader to compute a destination position for a fragment, where the destination position is independent of a position computed for the fragment during rasterization of a primitive. The destination position may be computed based on fragment parameters such as color, depth, and transparency. A raster operation unit writes processed fragment data to the destination position. Furthermore, the fragment program may configure the fragment shader to compute a per-fragment stencil operation for use by the raster operation unit during stencil buffering.

    摘要: Apparatuses and methods for detecting position conflicts during fragment processing are described. Prior to executing a program on a fragment, a conflict detection unit, within a fragment processor checks if there is a position conflict indicating a RAW (read after write) hazard may exist. A RAW hazard exists when there is a pending write to a destination location that source data will be read from during execution of the program. When the fragment enters a processing pipeline, each destination location that may be written during the processing of the fragment is entered in conflict detection unit. During processing, the conflict detection unit is updated when a pending write to a destination location is completed.

    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.
