A microcontroller fail-safe system includes a primary microprocessor coupled to a bus, and arranged for processing unprocessed signals received from the bus and for providing primary processed signals. A delay arrangement delays both the unprocessed and the primary processed signals by a predetermined period, to provide delayed signals. A secondary microprocessor is arranged for processing the delayed unprocessed signals and for providing secondary processed signals. A comparing arrangement compares the delayed primary processed signals and secondary processed signals such that the compared signals are synchronised through having experienced the same delay. |
