ABSTRACT:
The present invention concerns a software system that tolerates transient errors made up by a processing unit, including:at least two processing units (50, 51) with each one including:a microprocessor (54, 57),a memory (53, 56) protected by a device generating and controlling a code for the detection and correction of errors,a device (55, 58) for monitoring memory accesses,A centralized control device (52) for the processing units and for inputs/outputs, including:macro-synchronization means,data comparison/vote means,correction demand means,decision-making means,means allowing the inputs/outputs to be made.Some links (60, 61) respectively linking each processing unit to the device (52) for controlling the processing units and the inputs/outputs.
