This work proposes a Genetic Algorithm (GA) based on-line testing and recovery mechanism for reconfigurable critical digital circuits. Given the input / output specifications for a circuit, multiple versions (n) of the circuit are evolved using GA techniques. The n different versions are evolved to provide 100% fault coverage. A TMR fault tolerant circuit is designed using three different versi...

Reversible logic is emerging as an important research area having its application in diverse fields such as low power CMOS design, digital signal processing, cryptography, quantum computing and optical information processing. This paper presents a new 4*4 parity preserving reversible logic gate, IG. The proposed parity preserving reversible gate can be used to synthesize any arbitrary Boolean f...

The increasing demand of low complexity and error tolerant design in signal processing systems is a reliability issue at ground level. Complex circuit is consistently affected by soft errors in modern electronic circuits. Fast Fourier transforms (FFTs) plays a key role in many communication and signal processing systems. Different algorithms have been used in earlier techniques for achieving fa...

Quantum-dot cellular automata (QCA) is a newly-developed nanotechnology for next-generation nanoelectronic circuits. QCA circuits use the propagation of charge polarity in QCA cells to pass information without any current being involved. It has the advantages of extremely small size, low power consumption, high device density and twinkling operation process. Nanofabrication of QCA circuits may ...

Electronic circuits and systems used in mission and safety-critical applications usually employ redundancy in the design to overcome arbitrary fault(s) or failure(s) and guarantee the correct operation. In this context, the distributed minority and majority voting based redundancy (DMMR) scheme forms an efficient alternative to the conventional N-modular redundancy (NMR) scheme for implementing...

Biology demonstrates high levels of fault tolerance in all instances. This paper documents a demonstration system that takes inspiration from the immune system and embryonic processes to acquire some of these fault tolerant properties in hardware circuits. A multi-layer immune system is used as fault detection; a negative selection algorithm is used at a system level to identify non-self states...
