Abstract

The usefulness of three software fault tolerance techniques -- n-version programming, recovery blocks, and exception handling is examined within the context of real-time safety-critical environments. The general requirements of such application systems are presented and the techniques evaluated with regard to how well they satisfy these requirements.
