Patent US 8,502,829

A method and an apparatus are provided for combining multiple independent tile-based graphic cores. An incoming geometry stream is split into a plurality of streams and sent to respective tile based graphics processing cores. Each one generates a separate tiled geometry list as described. These may be combined into a master tiling unit or, alternatively, markers may be inserted into the tiled geometry lists which are used in the rasterization phase to switch between tiling lists from different geometry processing cores.
