Abstract

A processing system configured to process protected tasks, the processing system comprising: processing logic configured to process each of the protected tasks first and second times so as to generate, respectively, first and second processed outputs; a first fault detection unit operable in a mission mode in which it is configured to: compare the first and second processed outputs for a respective protected task; and generate a first signal indicative of whether said first and second processed outputs match; and a second fault detection unit operable in a mission mode in which it is configured to: compare the first and second processed outputs for the respective protected task; and generate a second signal indicative of whether said first and second processed outputs match; wherein the processing system is operable in a first protected mode in which: the first fault detection unit and the second fault detection unit operate, concurrently, in their respective mission modes; and the first signal and the second signal for the respective protected task are provided to a fault assessment unit for comparison in order to assess whether a fault existed at the first fault detection unit and/or the second fault detection unit when generating the first and second signals.
