<p>A microcontroller fail-safe system includes a primary microprocessor (20) coupled to a bus (80), and arranged for processing unprocessed signals received from the bus (80) and for providing primary processed signals. A delay arrangement (210) delays the unprocessed and the processed signals by a predetermined period, to provide delayed signals. A secondary microprocessor (120) is arranged for processing the delayed unprocessed signals and for providing secondary processed signals. A comparing arrangement (210) compares the delayed primary processed signals and secondary processed signals such that the compared signals are synchronised through having experienced the same delay.</p> |
