<p>A tile-based graphics processing system 3 has a write out stage 31 configured to compress depth data by dividing each depth value to be compressed into plural parts, forming plural depth data channels by associating corresponding ones of the plural parts of different depth values with each other and applying a data compression scheme separately to each depth data channel to be compressed in order to produce compressed representations of the depth data channels. The compressed representations of the depth data channels are written to external memory 34.</p> |
