1. A method of performing safety-critical rendering of a frame in a tile based graphics processing system, the method comprising:
receiving, at a rendering control unit, geometry data for the frame, a definition of a region in the frame and verification data, wherein the geometry data for the frame includes data defining a plurality of primitives representing a plurality of objects in the frame;
the region being associated with one or more primitives among the plurality of primitives;
the verification data associating one or more primitives with the region in the frame; and
rendering the frame using the geometry data and controlling the rendering of the frame using the verification data, so that the rendering excludes, from the frame outside the region, the primitives identified by the verification data.
