Two-Cycle Shift Register with Error Detection

摘要

The invention pertains to the area of computer technology. Single-crystal registers with error detection are known. However, in them the error detection block is suitable only for the class of single-cycle registers. Also known are two-cycle shift registers in which the emergence of undetected errors is possible. In the proposed two-cycle register, to increase the reliability of error detection the first outputs of the primary and auxiliary flip-flop of each digit are connected with the inputs of one element, EXCLUSIVE-OR, the output of which is connected with input of the first element OR, the second outputs of the main flip-flop of each digit and the auxiliary flip-flop of the following digit are connected with the inputs of each element EXCLUSIVE-OR, the output of which is connected with the input of the second element OR, the outputs of elements OR, are connected with the input of the element AND which corresponds to it, the other input of which is connected with output of the additional flip-flop, the inputs of which are connected with the main and auxiliary clock bus, and the outputs of element AND are connected to the inputs of the third element OR.
