No. 60/429,641 filed November 27, 2002, entitled “Dividing Work Among Multiple Graphics Pipelines Using a Super-Tiling Technique", having as inventors Mark M. Leather and Eric Demers, and owned by instant assignee.
The front end circuitry 35 generates the pixel data 36 by performing, for example, clipping, lighting, spatial transformations, matrix operations and rasterizing 0013
Alternatively, the third and fourth graphics pipelines may be configured to be on multiple chips interconnected by a communication path, for example, a synchronization signal or data bus.
This is accomplished, for example, by the back end circuitry 39 performing color, shading, blending, texturing and/or z—bul'fering operations on the pixels within the portions (e.g. 81-82) of the tiles (e.g. 72 and 75) they are responsible for.
