Matrix vector multiplication double-track logic circuit based on DNA composite strand displacement and method thereof

Abstract

The invention discloses a matrix vector multiplication double-track logic circuit based on DNA composite strand displacements and a method thereof; the method comprises the following steps: firstly building a three-row-three-column matrix and three-row-one column vector multiplication system according to a composite strand displacement combination mechanism; building a third-order matrix vector multiplication operated digit logic circuit; using a double-track idea to convert the digit logic circuit into a third-order matrix vector multiplication operated dual-track logic circuit; converting the dual-track logic circuit into a seesaw logic circuit; converting the seesaw logic circuit into a biochemical logic circuit; finally using Visual DSD simulation software to verify the outputted result and parse the three-row-three-column matrix and three-row-one column vector multiplication system complex dynamics behaviors, and enabling the simulation result to prove the result validity. The method provides basic theory basis for building a higher-order matrix vector multiplication in a later time and matrix and matrix multiplication logic operations, thus promoting the biology computer development, and improving the bio-computer logic circuit reliability.
