Abstract
A graphics processing system includes a plurality of processing units for processing tasks, each processing unit being configured to process a task independently from any other processing unit of the plurality of processing units; a check unit operable to form a signature which is characteristic of an output of a processing unit on processing a task; and a fault detection unit operable to compare signatures formed at the check unit; wherein the graphics processing system is configured to process each task of a first type first and second times at the plurality of processing units so as to, respectively, generate first and second processed outputs, wherein the check unit is configured to form first and second signatures which are characteristic of, respectively, the first and second processed outputs, and wherein the fault detection unit is configured to compare the first and second signatures and raise a fault signal if the first and second signatures do not match.
