摘要： A system and method for assigning operations to multiple pipelines in a graphics system is disclosed. The graphics system may include an arbitration unit coupled to a plurality of calculation pipelines. The arbitration unit is operable to provide graphics operations to selected ones of the calculation pipelines. Each of the calculation pipelines is operable to perform a graphics operation. Each of the calculation pipelines may include digital logic and/or a processing element for performing the graphics operations. An operation may be assigned to a pipeline if the pipeline is performing a low latency operation. A low latency operation may comprise an operation that is performed by one of the calculation pipelines in less time than a pre-determined number of clock cycles.

摘要： A graphics system and method for rendering a plurality of triangles. Information regarding the triangle may first be received. The method may then determine the longest edge or major edge of the triangle and also determine the direction or axis of the longest edge of the triangle. The method may then perform edge walking on the major edge (e.g., along the axis of the major edge) of the triangle, followed by span walking. The edge walking is preferably always performed on the major or longest edge of the triangle, prior to the span walking, and regardless of the orientation of the major edge of the triangle. This operates to load balance the edge walker and the span walker for the plurality of triangles.

摘要： A graphics system and method are disclosed that may optimize the rate of pixel generation to match the rate at which a memory may be designed to receive pixel data. If a memory is configured to store multiple pixels substantially simultaneously, it may be advantageous to render an equivalent number of pixels substantially simultaneously and at the same rate. An edge walker that utilizes multiple sets of accumulators to generate multiple scan lines substantially simultaneously and a span walker that utilizes multiple sets of accumulators to render multiple pixel values substantially simultaneously is described.

摘要： A system and method for rendering a polygon, such as a triangle. The method may comprise receiving geometry data (or vertex data) defining vertices of the polygon. The method may compute initial vertex x,y values at end points proximate to each of the vertices of the polygon, and a slope value along each edge of the polygon. The computed slope may be a quantized slope value having a first number of bits of precision. The first number of bits of precision may produce inaccuracies for interpolated x,y values computed at the end points of an edge of the polygon. The method may then interpolate x,y values along each respective edge of the polygon using the computed slope along the respective edge of the polygon. Finally the method may store final x,y values for each respective edge of the polygon. The final x,y values comprise the interpolated x,y values for non-end points of the respective edge, and the computed initial vertex x,y values for each of the end points of the respective edge. The operation of storing the computed initial vertex x,y values for each of the end points of the respective edge, instead of using interpolated x,y values at the end points, operates to prevent inclusion of an extraneous pixel and/or exclusion of a pixel within the polygon.
摘要翻译： 用于渲染多边形（如三角形）的系统和方法。 该方法可以包括接收定义多边形顶点的几何数据（或顶点数据）。 该方法可以在靠近多边形的每个顶点的端点处计算初始顶点x，y值，以及沿多边形的每个边缘的斜率值。 所计算的斜率可以是具有第一数位精度的量化斜率值。 对于在多边形边缘的端点处计算出的内插x，y值，第一个精度位可能会产生不准确。 然后，该方法可以使用沿多边形的相应边缘的计算斜率来内插多边形的每个相应边缘的x，y值。 最后，该方法可以存储多边形的每个相应边缘的最终x，y值。 最终的x，y值包括相应边缘的非端点的内插x，y值以及相应边缘的每个端点的计算的初始顶点x，y值。 存储相应边缘的每个端点的计算的初始顶点x，y值而不是在端点处使用内插的x，y值的操作，以防止包含外部像素和/或排除 多边形内的像素。

摘要： A graphics system and method for displaying lines on a display device. The system may comprise a sample buffer, a rendering unit and a sample-to-pixel calculation unit. The rendering unit may (a) generate a plurality of sample positions in a two-dimensional space, (b) determine a sample normal distance for each of the sample positions with respect to a line defined by the line-draw command, (c) assign sample values to the sample positions based on the sample normal distance of each of the sample positions, and (d) store the sample values in the sample buffer. The sample-to-pixel calculation unit may read sample values from the sample buffer, filter them to determine a pixel value, and transmit the pixel value to the display device. The rendering unit may render the line sample values with a narrower width to pre-compensate for the line-expanding effect of the filtering performed by the sample-to-pixel calculation unit.
