摘要： Embodiments for programming a graphics pipeline, and modules within the graphics pipeline, are detailed herein. Several of these embodiments utilize offset registers associated with the instruction tables for the modules within the pipeline. The offset register serves as a pointer to locations in the instruction table, which allows instructions to be written to be instruction table, without requiring that the shader programs have explicit addresses. One embodiment describes a method of programming a graphics pipeline. This method involves accessing the shader program stored in memory. A shader instruction is generated from this shader program, and loaded into an instruction table associated with a target module graphics pipeline. The shader instruction is loaded into the instruction table at the location indicated by an offset register.

摘要： Early Z scoreboard tracking systems and methods in accordance with the present invention are described. Multiple pixels are received and a pixel depth raster operation is performed on the pixels. The pixel depth raster operation comprises discarding a pixel that is occluded. In one exemplary implementation, the depth raster operation is done at a faster rate than a color raster operation. Pixels that pass the depth raster operation are checked for screen coincidence. Pixels with screen coincidence are stalled and pixels without screen coincidence are forwarded to lower stages of the pipeline. The lower stages of the pipeline are programmable and pixel flight time can vary (e.g., can include multiple passes through the lower stages). Execution through the lower stages is directed by a program sequencer which also directs notification to the pixel flight tracking when a pixel is done processing.

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.

摘要： A pixel processing system and method which permits rendering of complicated three dimensional images using a shallow graphics pipeline including reduced gate counts and low power operation. Pixel packet information includes pixel surface attribute values retrieved in a single unified data fetch stage. A determination is made if the pixel packet information contributes to an image display presentation (e.g., a depth comparison of Z values may be performed). The pixel packet information processing is handled in accordance with results of the determining. The pixel surface attribute values and pixel packet information are removed from further processing if the pixel surface attribute values are occluded. In one exemplary implementation, the pixel packet includes a plurality of rows and the handling is coordinated for the plurality of rows. Any of a number of downstream pipestages may remove the occluded pixel information, and in response thereto, may notify a gatekeeper pipestage of the slack increase so that more pixels can be allowed into the pipeline.
