Abstract: A circuit module for performing matrix multiplication and a method for performing matrix multiplication are provided. The circuit module includes a row-column calculation unit for performing a row-column multiplication calculation. The row-column calculation unit includes a multiplication unit and an addition unit. The multiplication unit is configured to perform a multiplication calculation based on a row matrix element of a first matrix and a column matrix element of a second matrix, and receive at least one electrical signal sequentially inputted in multiple predetermined timing sequences via an input end of the multiplication unit. The electrical signal represents the row matrix element of the first matrix. The addition unit is configured to accumulate a product, obtained by the multiplication unit based on the inputted electrical signal, to perform the row-column multiplication calculation.

Abstract: A voltage detection circuit and method for an integrated circuit, and an integrated circuit are provided. The voltage detection circuit includes: a first current source, a first branch and a second branch. A current outputted by the first current source is allocated to the first branch and the second branch. The first branch includes a first voltage control current component and a first load connected in series. The second branch includes a current signal detection component and a second load connected in series. A voltage signal to be detected is inputted to a control signal input terminal of the first voltage control current component. The current signal detection component is configured to output, in real time, a preset signal characterizing a second current flowing through the second branch, to determine change of the voltage signal to be detected based on the preset signal.
