Abstract: The present application discloses a Hamming weight calculation method performed by an operation apparatus. The operation apparatus includes a controller and a first calculator, wherein the controller sets an initial resistance state of the first memory to a low resistance state; determines a first gate voltage of the first transistor based on first bit data in a first binary sequence, and control an on-off state of the first transistor based on the first gate voltage; controls a target resistance state of the first memory based on the on-off state of the first transistor; and determines a Hamming weight of the first bit data based on a first output current on the source of the first transistor.

Abstract: A detection circuit includes a first pulse sequence generator configured to generate a first pulse sequence based on a first signal and a second pulse sequence generator configured to generate a second pulse sequence based on a second signal. Amplitudes and frequencies of the first signal and the second signal are different. The detection circuit further includes a first conductance device configured to receive the first pulse sequence to generate a first conductance, a second conductance device configured to receive the second pulse sequence to generate a second conductance, and a difference detection circuit configured to, when both the first conductance device and the second conductance device receive a third signal, output a voltage representing a difference between the first conductance and the second conductance. The detection circuit can be applied to an image edge detection scenario.
