Abstract

The invention relates to a thermometer decoding method and circuit, belongs to the field of integrated circuits, and is simple in logic, not easy to make mistakes and high in reliability. The thermometer decoding method comprises the following steps: splitting an N-bit binary code into at least one group of high-order continuous bits and low-order continuous bits meeting a preset bit number condition; if a group of M-bit high-order continuous bits and K-bit low-order continuous bits are obtained through splitting, K and M both meet the preset bit number condition and K = N-M, executing the decoding step comprising the following steps S1 and S2: S1, the M-bit high-order continuous bits are decoded into (2M-1)-bit row selection thermometer codes by a row temperature decoding module, and the column temperature decoding module decodes K-bit low-order continuous bits into (2K-1)-bit column selection thermometer codes; S2, 2N-1 basic logic particle units carry out logic processing on the row selection thermometer code and the column selection thermometer code to obtain a (2N-1)-bit thermometer code.

Description

technical field [0001] The present disclosure relates to the field of integrated circuits, and in particular, to a thermometer decoding method and circuit. Background technique [0002] The traditional thermometer decoding method is to first use the truth table to list the output state values ​​of the thermometer decoding corresponding to all inputs, then list the logical expressions and simplify the expressions, and finally obtain the combinational logic corresponding to each bit of the thermometer code circuit. The process of this method is cumbersome and error-prone. Contents of the invention [0003] The purpose of the present disclosure is to provide a thermometer decoding method and circuit, which has simple logic, is not easy to make mistakes, and has high reliability. [0004] According to the first embodiment of the present disclosure, a thermometer decoding method is provided, including: splitting an N-bit binary code into at least one group of high-order conti...
