computer system, which is designed to be resilient to transient faults, and procedures for managing the system

摘要

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.
