Universal error-correction circuit with fault-tolerant nature, and decoder and triple modular redundancy circuit that apply it

摘要

The present invention provides a universal error-correction circuit with fault-tolerant nature, and a decoder and a triple modular redundancy circuit that apply it, where the universal error-correction circuit with fault-tolerant nature includes: an error-correction unit with fault-tolerant nature implemented by a logic gate, where digital input signals of the error-correction unit with fault-tolerant nature are separately I 0 , I 1 ..., I 2 k -1 , and I 2 k , digital output signals of the error-correction unit with fault-tolerant nature are separately O 0 , O 1 ..., O k -2 , and O k -1 , and the digital input signals and the digital output signals belong to a set {0,1}, where k is a positive integer. The error-correction unit with fault-tolerant nature is configured to: when k=1, set O 0 = I 0 if I 0 = I 1 , and O 0 = I 2 otherwise; and when k1, set O k -1 = I 2 k -1 if O k -2 =I 2 k -1 , and O k- 1 = I 2 k otherwise. Because a logical relationship between input and output is uniquely certain, the error-correction circuit with fault-tolerant nature may be implemented only by a logic gate. There may be a plurality of specific implementation manners, as long as input and output meet the uniquely certain logical relationship of the present invention. Therefore, the error-correction circuit with fault-tolerant nature provided by the present invention is provided with general commonality.
