A TILE BASED GRAPHICS PROCESSOR AND A METHOD OF PERFORMING GRAPHICS PROCESSING IN A TILE BASED GRAPHICS PROCESSOR

摘要

A graphics processing apparatus and method of performing graphics processing are provided. The graphics processing apparatus comprises a sequence of processing stages capable of performing graphics processing to generate a frame of display data. The graphics processing is performed on a tile-by-tile basis. The graphics processing apparatus is capable of determining if a current tile subject to the graphics processing is empty. At least one processing stage of the sequence of processing stages is omitted for graphics processing of the current tile in dependence on whether the current tile is empty.
