Mitigation of software errors produced by radiation from the space environment

Abstract

This paper presents the development and implementation of a software error mitigation technique with the aim of protecting functions to be used in space missions. The Preemptive Control Signature technique is analyzed to mitigate Single Event Upset type errors on the ARMv7E-M architecture and thus be able to extend the availability time of spatial devices by increasing tolerance to such errors. Implemented technique detected 79.5% of the errors.
