Boolean-Complement Based Fault-Tolerant Electronic Device Architectures

We propose new fault-tolerant architectures, which, in contrast to the well-known double and triple modular redundancy architectures, include only one copy of the original circuit. In the new architectures, a signal error detection circuit is used to select the functions to be corrected. The circuit is built on the basis of the Boolean complement method with parity check of calculations. A generalized architecture with Boolean complement based signal correction is presented. This architecture permits one to design the simplest fault-tolerant circuits. Algorithms for designing signal error detection circuits, as well as examples of their application, are given.
