Patent ID: 8339409

Claim:
A tile-based graphics system for generating graphics data for a frame comprising a plurality of tiles, comprising: an input means for receiving a plurality of graphics primitives for the frame; graphics processing circuitry configured to operate in a first mode of operation and a second mode of operation; in said first mode of operation said graphics processing circuitry receiving said plurality of graphics primitives from said input means, and being configured to perform a binning operation to determine, for each of said plurality of tiles, a tile list identifying the graphics primitives from amongst said plurality which intersect that tile; in said second mode of operation, said graphics processing circuitry receiving said tile list for an allocated tile, and being configured to perform a rasterization operation to generate said graphics data for said allocated tile dependent on said tile list; and control circuitry for controlling switching of the graphics processing circuitry between said first mode of operation and said second mode of operation.
