Abstract :
Robust-fault-tolerant arithmetic circuits for a highly safe digital system are proposed. Two kinds of robust-fault-tolerant arithmetic circuits based on distributed coding are designed. One is a robust-fault-tolerant adder, and the other is a robust-fault-tolerant multiplier. It is shown in an experiment of robot control that the safety of the proposed arithmetic circuits is superior to that of the ordinary binary arithmetic circuits
