Abstract
A graphics processing system for performing tile-based rendering of a scene that comprises safety-related primitives. The system comprises a plurality of graphics processing units (GPUs), each configured to i) receive tile data identifying one or more protected tiles comprising at least part of a safety-related primitive, ii) process two respective sets of protected tiles, and iii) based on said processing, generate two respective checksums for each respective set of protected tiles. The two respective sets of protected tiles are mutually exclusive, and each respective set and each protected tile being processed by two different GPUs. The system comprises a comparison unit configured to compare one or more pairs of checksums, each pair comprising a respective checksum generated based on a same respective set of protected tiles and generated by different GPUs. The graphics processing system is configured to perform one or more actions based on an outcome of said comparison.
