    • 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.

    • 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.
    • 本发明的像素处理系统和方法允许使用包括减少的栅极数量的浅图形管线来呈现复杂的三维图像,并且还有助于功率节省。 像素分组信息包括像素表面属性值在单个统一数据获取阶段检索。 在数据提取管线处,可以确定像素分组信息是否有助于图像显示呈现(例如,执行Z值的深度比较来确定像素是否被遮挡)。 像素分组状态指示符(例如,杀死比特)被设置在像素分组的边带部分中,并且像素分组被转发以根据像素分组状态指示符进行处理。 如果状态指示符指示像素分组有效载荷对图像显示呈现不起作用,同时继续对像素分组边带信息进行时钟处理,则状态指示符是设置为防止逻辑组件针对像素分组的有效载荷部分的时钟信息。
