摘要：NOVELTY - The method involves separating a system input signal into three paths for entering into three data processing units, respectively. An instruction control is processed to input data. Calculating information is recorded in data buffering areas, respectively. Data in the areas is input to a voting logic unit. A monitoring unit is mount. Signals of the processing units and the logic unit are transmitted to a multi-path switch. A signal that is output to an expansion bus is determined by the multi-path switch according to a judgment given by the logic unit. USE - Method for realizing a triplet instruction of a fault-tolerant controller. ADVANTAGE - The method realizes triplet instruction of fault-tolerant controller to be executed synchronously, completes data synchronous calculation of three channels and ensures reliability. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a triplet instruction realizing method. '(Drawing includes non-English language text)'.
