Abstract

The invention relates to a four-steady-state RS trigger supporting multiple-valued logic, and belongs to the technical field of digital circuits. The four-steady-state RS trigger specifically comprises four NAND gates G1, G2, G3 and G4, and two XOR gates G5 and G6, wherein the NAND gate G1, the NAND gate G2, the NAND gate G3 and the NAND gate G4 respectively comprise two input ends and an output end, and the XOR gate G5 and the XOR gate G6 respectively comprise an input end and an output end. Two inputs of the four-steady-state RS trigger are S and R, and two outputs of the four-steady-state RS trigger are Q and N and namely are the output of the NAND gate G1 and the output of the NAND gate G2. Four states 00, 01, 10 and 11 which can be kept continuously can be obtained, and the four-steady-state RS trigger can be used for building a molecular computer based on the multiple-valued logic of digital circuits.

Description

technical field [0001] The invention relates to a four-stable RS flip-flop supporting multi-valued logic, which belongs to the technical field of digital circuits. Background technique [0002] Molecular computing is based on multi-valued logic, and the quad-stable RS flip-flop is one of the basic components for building molecular computing based on digital logic circuits. Molecular computing uses DNA encoded by bases (A, T, C, G) as "data", DNA biochemical reactions as "operations", DNA before the reaction as the "input" of the problem, and DNA after the reaction as the "output". After polynomial time "operation", the "answer" is finally obtained and read out. [0003] Molecular computing is a space-based processing model, which can generate, process and store exponential data at the same time through efficient information encoding and huge parallel storage and processing systems, and realize exponentially accelerated calculation and time-space complexity conversion.
