Embodiment 1

[0019] Such as figure 1 , 2 And shown in 5, in the present embodiment and be four digits, therefore, " summand " A 0 B 1 C 0 D. 1 with "addend" a 0 b 1 c 1 d 1 The substances in the corresponding bits are XORed from right to left.

[0020] Among them, D1+d1=D0p+Ct+d1; d1 is the catalyst, and the reaction remains unchanged, D0p is the intermediate product of the first step, and Ct is the carry material of the D material position.

[0021] C0+c1=C1p+c1; c1 is the catalyst, the reaction remains unchanged before and after, C1p is the intermediate product of the first step, C1p is converted into C1p+Ct=Copp+Ct+Bt under the catalysis of the carry material Ct; Copp is the next One-step intermediate product, Bt is the carry material of C material position.

[0022] B1+b1=B0p+At+b1; b1 is the catalyst, the reaction remains unchanged, Bop is the intermediate product of the first step, At is the carry material of the B material position, B0p is converted into B0p+ under the cat...

Abstract

The invention discloses a method for calculation of a CRNs adder based on bistable state reaction. The method comprises the following steps: S1 of setting parameters; S2 of adding an augend and an addend, causing materials of the corresponding positions of the augend and the addend to undergo XOR reaction simultaneously, and obtaining a first-step intermediate product and a carry material; S3 of converting the first-step intermediate product into an intermediate product of a next step under catalysis of the carry material; converting an intermediate product of each step into a corresponding final product, and finally obtaining a stable result under the bistable state reaction. According to the method, a complex circuit structure in the digital circuit adder is not needed, and a concise and efficient calculation mode is sought, so that the augend is quickly and stably converted into a computed result through the intermediate product under the catalysis effect of the addend.

Description

technical field [0001] The invention belongs to the calculation field of chemical reaction networks (CRNs), in particular to a calculation method for CRNs adders based on bistable reactions. Background technique [0002] In 2011, PhillipSenum and others proposed "Rate-Independent Constructs for Chemical Computation", which realized the addition operation at the molecular concentration level. However, molecular concentration is rarely used in digital circuits as a quantification unit, and the accuracy of calculation results needs to be improved, so chemical reaction networks (CRNs) need precise binary adders. That is, in CRNs, each bit of a binary number uses two chemical substances to represent logic values ​​1 and 0 respectively, and the two substances ensure the uniqueness of the bit 0 and 1 through a bistable reaction. In this way, matter representing two binary numbers interacts to produce matter representing "and". [0003] In 2013, JiangHua et al. proposed "DigitalLo...
