System and method for triangle rasterization with frame buffers interleaved in two dimensions

摘要

A method and apparatus is provided for interleaving frame buffer controllers in two dimensions. Each frame buffer controller includes an edge stepper, a subspan stepper and a span stepper. The subspan stepper separates each span line into a plurality of parts. Each frame buffer controller provides pixel data for certain parts of the span line. The parts are defined by a start value, a stop value and a starting color value.
