摘要： A system, method and computer program product are provided for depth clamping in a hardware graphics pipeline. Initially, a depth value is identified. It is then determined as to whether a hardware graphics pipeline is operating in a depth clamping mode. If the hardware graphics pipeline is operating in the depth clamping mode, the depth value is clamped within a predetermined range utilizing the hardware graphics pipeline.

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 adjusts floating-point-valued images prior to conversion to a display signal so that the dynamic range of the display device is effectively used. Images are adjusted using transfer functions to create an adjusted image within the dynamic range of the display device. The adjusted image also has a frequency distribution of pixel values to maximize the perception of visual detail. The system generates transfer functions from statistical attributes of one or more images. The transfer functions are applied to images on the fly as they are converted into a display signal. The statistical attributes of the image are computed on the fly as it is converted into a display signal. A first transfer function is applied to an image to produce an adjusted image in parallel with the generation of a second transfer function to be applied to a future image.

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.
