Description
Summary:This paper describes the implementation of a CPU which can operate successfully in hostile environments such as an orbiting space vehicle. The design goal is to reduce sensitivity to the effects of radiation which can cause malfunctions in electronic circuit or a complete failure of the system. Moreover, to test performance and collect data, special hardware structures are integrated on silicon to collect data on detected errors.
