Evaluation of a software-based error detection technique by RT-level fault injection

Abstract

This paper discusses the efficiency of a software hardening technique when transient faults occur in the processor elements. Faults are injected in the RT-Level model of the processor, thus providing a more comprehensive view of the robustness compared with injections limited to the registers in the programmer model (e.g. injections based on an Instruction Set Simulator or using instructions of the processor to modify contents of registers).
