Originální abstrakt

This work focuses on the roll-back and roll-forward lockstep architecture that are techniques to detect faults like SEU, voltage dips or another impacting to system misbehaviour. These techniques are explored using FMEA analysis and on its basis, some propose is presented that improves reliability and safety of each technique. In this case, availability is lowered as a trade of higher reliability and safety. These techniques are also explored from the point of view using in real-time systems. On this basis, some recommendations of appropriate checkpointing in lockstep roll-back technique is presented.
