Using electronic systems to control complex applications has found its way into nearly all technical and industrial areas during the last four decades. Today, in addition to system size, reduced system costs, optimized energy consumption and high reliability or safety, the aspects of functional safety are increasingly in the focus of many applications. Especially concerning safe embedded cyber-physical systems, which is favored by increasing integration of components, these aspects are of central importance. This article describes a consistently safety 1oo2 SoC architecture model (a miniaturized safety system on a chip) based on a modified software comparator architecture. The design and realization of the safety SoC, according to IEC 61508, are also presented.
