    摘要: Processing pixels in a graphics pipeline. Screen coincidence between a first pixel and a second pixel in a graphics pipeline is detected, wherein the first pixel has entered a downstream pipeline portion of the graphics pipeline but has not yet completed processing within the graphics pipeline. In response to detecting the coincidence, propagation of the second pixel to the downstream pipeline portion is stalled until the first pixel completes processing within the graphics pipeline. A data cache associated with the data fetch stage is invalidated in advance of a data fetch stage of the downstream pipeline portion obtaining data for the second pixel.

    摘要: A rasterizer stage configured to implement multiple interpolators for graphics pipeline. The rasterizer stage includes a plurality of simultaneously operable low precision interpolators for computing a first set of pixel parameters for pixels of a geometric primitive and a plurality of simultaneously operable high precision interpolators for computing a second set of pixel parameters for pixels of the geometric primitive. The rasterizer stage also includes an output mechanism coupled to the interpolators for routing computed pixel parameters into a memory array. Parameters may be programmably assigned to the interpolators and the results thereof may be programmably assigned to portions of a pixel packet.

    摘要: A present invention pixel processing system and method permit complicated three dimensional images to be rendered with shallow graphics pipelines including reduced gate counts and also facilitates power conservation. Pixel packet information includes pixel surface attribute values are retrieved in a single unified data fetch stage. At a data fetch pipestage a determination may be made if the pixel packet information contributes to an image display presentation (e.g., a depth comparison of Z values is performed determine if the pixel is occluded). A pixel packet status indicator (e.g., a kill bit) is set in the sideband portion of a pixel packet and the pixel packet is forwarded for processing in accordance with the pixel packet status indicator. The status indicator is a kill bit is set to prevent logic components from clocking information for a payload portion of the pixel packet if the status indicator indicates the pixel packet payload does not contribute to the image display presentation while continuing to clock pixel packet sideband information.
