1. A graphics processing system for performing tile-based rendering of a scene, wherein the system comprises:
a plurality of graphics processing units, wherein each graphics processing unit is configured to i) receive tile data identifying one or more protected tiles, ii) process two respective sets of the protected tiles, and iii) based on said processing, generate two respective checksums, one for each respective set of protected tiles, wherein each respective set of protected tiles is processed by two different graphics processing units; and
a comparison unit configured to compare one or more pairs of checksums, wherein each pair comprises a respective checksum generated based on a same respective set of protected tiles and generated by different graphics processing units, and wherein the graphics processing system is configured to perform one or more actions based on an outcome of said comparison.
