Duplicated control unit based embedded fault-masking systems

Abstract

Fault-masking architectures are classified into a few major categories. The first is the multiplication of the microcontroller, the other is a CON-MON architecture (not a full-fledged fault-masking system), there is of course, the multiplication of frequently failing units. In this article, the focus is on the different kind of solutions, how can a duplicated microcontroller based system, monitoring itself, and increasing the fault-tolerance level of the embedded system.
