A tile based graphics processing pipeline comprises a plurality of processing stages, including at least a rasterizer that rasterizes input primitives to generate graphics fragments to be processed, and a renderer that processes fragments generated by the rasterizer to generate rendered fragment data, and a processing stageoperable to receive rendered fragment data, and to perform a processing operation using the rendered fragment data to generate per-tile metadata

Graphics processing systems

A tile-based graphics processing pipeline comprising a rasteriser, a renderer, a tile bufferconfigured to store rendered fragment data locally to the graphics processing pipeline prior to that data being written out to an external memory, a write out stageconfigured to write data stored in the tile buffer to an external memory, and a programmable processing stage. The programmable processing stageis operable under the control of graphics program instructions to read fragment data stored in the tile bufferon a random access basis, perform a processing operation using the read fragment data, and write the result of the processing operation into the tile bufferor to an external memory.
