ABSTRACT:
A graphics system comprising a set of rendering processors and a series of filtering units. Each of the rendering processors couples to a corresponding one of the filtering units. Each rendering processor RP(K) is configured to (a) generate a stream of samples in response to received graphics primitives, (b) add a dither value DKto a data component of each the samples in the stream to obtain dithered data components, (c) buffer the dithered data components in an internal frame buffer, and (d) forward a truncated version of the dithered data components to the corresponding filtering unit. The filtering units are configured to perform a weighted averaging computation on the truncated dithered data components in a pipelined fashion to determine pixel data components.
