Quad-Fault Tolerant Architecture Design for Ripple Carry Adder

Vayalasetti Swarnalatha, Praveen Kumar Polisetty

Volume : VOLUME 2 || Issue : ISSUE 5

Abstract :

We consider quad fault cases and show   how a system can reconfigure from an error causing four faults at maximum. A system must be fault tolerant to decrease the failure rate and increase the reliability of it. Multiple faults can affect a system simultaneously and there is a trade-off between area overhead and number of faults tolerated. Fault tolerant architecture design for a ripple carry adder assuming quad faults.
