Evolving Reversible Fault-Tolerant Adder Architectures and their Power Estimation
2014
Fault tolerance property is incorporated in a circuit to increase its reliability. Error at the output side can be prevented by Fault-tolerant circuits. Its design enables the circuit to continue operation, at an error-free state, rather than failing completely, when some part of the circuit fails. Here, reversible adder fault-tolerant architectures of ripple carry, carry look-ahead adder (CLA) and carry skip adder (CSA) are implemented and their corresponding powers are estimated. Power efficiency and reliability of the implemented adders make them effective.
