Abstract :
The paper describes a fault tolerant system that is based on two replicas of a self checking module and on an error masking interface. The main contributions of this work rely on the fail safe/strongly fail safe design of the error masking interface, and on the analysis of the competitiveness of this fault tolerant scheme with respect to its reliability
