Novel architectures for TSC/CD and SFS/SCD synchronous controllers
S.M. Kia, Sri Parameswaran · 2002
Introduces design models for totally self checking, code disjoint (TSC/CD) and strongly fault secure, strongly code disjoint (SFS/SCD) synchronous controllers. The TSC/CD and SFS/SCD models are based on two new proposed low-cost, modular, totally self checking (TSC), edge triggered and error propagating (code disjoint) flip-flops; one, a D flip-flop which can be used in TSC and strongly fault secure (SFS) synchronous circuits with two-rail codes; the other a T flip-flop, used in a similar way as the D flip-flop but retaining the error as an indicator until the next presetting, as an aid to error propagation.>
