Annotation
Services a system delivers are called dependable when it is trustworthy enough that reliance can be placed on them because they are available, reliable, safe and secure. In the contribution, our approach to modelling and design of components for the construction of dependable time-critical systems implemented by means of RT kernel is presented. On top of that, faults and errors in components and RT kernels are classified in the contribution. Safety of the components is verified by means of the UPPAAL tool. Reliability is solved by means of time-redundancy and spatial redundancy, both implemented on RT task scheduling level. Proposed solution is analyzed from view of schedulability of the resulting time-redundant set of RT tasks and its implementation is demonstrated by means of uC/OS-II kernel.
