A kind of multi-cell signal size comparator, comparison method and application

Abstract

The invention discloses a multi-cell signal size comparator, a comparison method and an application. The comparator includes four kinds of bacterial cells, the first cell and the second cell are input receiving cells, and the third cell and the fourth cell are result output cells; The first cell corresponds to the first input bit, the second cell corresponds to the second input bit, the third cell corresponds to the first output bit, and the fourth cell corresponds to the second output bit; between the first cell and the third cell The first chemical line or the second chemical line communicates, the second cell and the third cell communicate through the second chemical line, the first cell and the fourth cell communicate through the second chemical line, the second cell and the fourth cell They communicate with each other through the second chemical line or the third chemical line. Through multi-cell cooperation, the size judgment of the input signals of two input bits can be judged, and whether the two input bit signals are equal can be used in related applications such as biological computers that require size comparison.

Description

technical field [0001] The invention relates to the technical field of cell computers, in particular to a multi-cell signal size comparator, comparison method and application. Background technique [0002] The construction of cellular computing components is one of the current hot issues. At present, various logic gates such as cellular AND, OR, and NOT, as well as cellular computing components such as bistable switches, memories, and counters, have been successfully constructed. A comparator is a basic computing component that compares two or more data items to determine whether they are equal, or to determine the magnitude relationship between them. A circuit or device capable of performing this comparison function is called a comparator. [0003] The current cell comparator such as "Construction of a genetic comparator in Escherichia Coli" (Chen Mei, IEEE Access, vol.7, pp.85024-85028, Jun, 2019) published by the inventor in the paper, and as the inventor previously Pa...

AI Technical Summary

Problems solved by technology

[0004] (1) Only one cell accepts input, so only different signals can be judged, and the same signal cannot be judged (that is, equal judgment cannot be made)

If the biological computer needs to compare the results of two sub-tasks to determine the next step during operation, and the results of the two tasks are equal in size (a signal), the above-mentioned calculation components can only use it as an input , resulting in an error;

[0005] (2) The user needs to know the type of the signal to be compared before the calculation. If the biological computer needs to compare the results of the two subtasks to determine the next step during the operation, the user needs to first identify the substance type of the result Then compare and calculate, adding an intermediate step
