Modular input‐parallel output‐series DC/DC converter control with fault detection and redundancy

Fault Tolerance with Multiple Task Modular Redundancy

The redundant units in a classic N Modular Redundancy (NMR) system are employed solely for fault tolerance, making this technique inefficient. This paper introduces Multiple Task Modular Redundancy that allows an NMR system to have a higher throughput by exploiting, when no faults have occurred, the system’s redundancy. More than one group of replicated tasks are optimistically executed. This m...

Fault Tolerant and Correction System Using Triple Modular Redundancy

An alternative way to have a fault less system is Fault Tolerant System, Triple Modular Redundancy (TMR) is used for making a fault tolerant system.. FPGA platform used in Altera Cyclone kit and Altera Quartus software is for functional and timing simulation. This model not only detects the faulty processor but also repair the faulty bits in the faulty processor .Fault detection are done over t...

Transfer Function of Triple Modular Redundancy Fault-tolerant sensors system

This paper formulates the transfer function of Triple Modular Redundancy (TMR) Fault-tolerant sensors system. The first attempt was to present a practicable model of a triple modular redundancy faulttolerant system for sensors working synchronously with same input. Analogues and digital sensors are separately modeled to show the difference in their transfer functions as resulted from their diff...

On-demand Fault Scrubbing Using Adaptive Modular Redundancy

We present an architectural framework for NModular Redundant (NMR) systems exploiting the dynamic partial reconfiguration capability of FPGAs. Partial reconfiguration is used to dynamically construct the throughput datapath under failure conditions. The throughput datapath utilizes only one instance of a Functional Element (FE) while the other instances undergo evaluation by being subjected to ...
