Abstract
A graphics processing system with a data store includes processing units for processing tasks. A check unit forms a signature which is characteristic of an output from processing a task on a processing unit, and a fault detection unit compares signatures formed at the check unit. Each task is processed first and second times at the processing units to generate first and second processed outputs. The graphics processing system write outs the first processed output to the data store, reads back the first processed output from the data store and forms at the check unit a first signature characteristic of the first processed output as read back from the data store; forms at the check unit a second signature characteristic of the second processed output, compares the first and second signatures at the fault detection unit, and raises a fault signal if the signatures do not match.
