Abstract :
For some applications, such as aircraft control, military communications etc., these should have a larger mean time to failure (MTTF). This is why N-modular redundancy (NMR) is used instead of triple modular redundancy to increase the MTTF. However, the reliability of the fault-tolerance system decreases as the faulty modules increase. The reconfiguration 5MR can improve this problem. It can tolerate up to three faulty modules in a 5MR systems. But for N >5, the design is more difficult and accordingly the hardware becomes more complicated. The authors introduce a general version of the reconfiguration NMR (GVRNMR) system. Not only does it simplify the design process, but it also decreases the hardware complexity
