where I, Ierror are the conventional implementation without soft error injection and the implementation (conventional or stochastic approach) in case of injecting soft error. Table 4.2 shows that the traditional approach is more sensitive to the variation caused by the injected soft error, while SC is seem to be stable with an reliable quality at the output. Therefore, the fault–tolerant capacity of SC is definately better than one of conventioanl computing.
