    • A block expanding section and a plurality of pixel processing sections are formed in the same semiconductor chip. The block expanding section handles an area to be drawn in units of blocks each composed of an appropriate number of pixels and performs expansion calculation of information of a representative value of each block. Each of the plurality of pixel processing sections has a pixel expanding section and a computing section. The pixel expanding section expands information in units of pixels at least in a rectangular area from block representative point information calculated in the block expanding section. The computing section performs computation in units of pixels information-expanded by the pixel expanding section. Each of the plurality of pixel processing sections selectively performs either graphics processing performed in cooperation with the block expanding section, or image processing performed independent of the block expanding section.
    • 在相同的半导体芯片中形成块扩展部分和多个像素处理部分。 块扩展部分处理以每个由适当数量的像素组成的块为单位绘制的区域,并执行每个块的代表值的信息的扩展计算。 多个像素处理部中的每一个具有像素扩展部和运算部。 像素扩展部分至少在矩形区域中以从块扩展部分中计算出的块代表点信息的像素为单位扩展信息。 计算部以像素扩展部扩展的像素为单位进行计算。 多个像素处理部分中的每一个选择性地执行与块扩展部分协同执行的图形处理,或独立于块扩展部分执行的图像处理。

    • An apparatus of drawing graphics includes an edge coefficient calculator calculating, from vertex data on vertices of a triangle, edge coefficients of edge functions used to determine whether a pixel is present in an inside region of the triangle, and a bounding box calculator calculating a bounding box of projected images of the triangle on a projection plane based on the edge coefficients. The apparatus also includes a starting point determiner and a traverser. The starting point determiner classifies the projected images of the triangle based on a combination of the edge coefficients for respective sides of the triangle, and determines a scan starting point from a corner of the bounding box based on classification of the projected images. The traverser generates pixel data used in rasterization by scanning the bounding box from the scan starting point.
    • 绘制图形的装置包括边缘系数计算器,从三角形顶点的顶点数据计算用于确定像素是否存在于三角形的内部区域中的边缘函数的边缘系数,以及边界框计算器,计算边界 基于边缘系数在投影平面上的三角形的投影图像的框。 该装置还包括起点确定器和横越器。 起始点确定器基于三角形的相应边缘的边缘系数的组合来对三角形的投影图像进行分类,并且基于投影图像的分类从边界框的角确定扫描起始点。 遍历器通过从扫描起始点扫描边界框来生成光栅化中使用的像素数据。
