A description of the design and an analysis of the fault-tolerance characteristics of the A129 integrated multiplex system (IMS) are presented. The A129 IMS is a computer system designed to implement automatic flight control, navigation, system monitoring, and other flight-critical and mission-related tasks. The fault-tolerance design philosophy has been to implement the majority of the fault detection and redundancy management features in software as opposed to hardware. The resulting system has been shown, via a Markov reliability analysis, to possess high reliability during a three-hour mission.
