摘要： Embodiments of this application disclose a Hamming weight calculation method based on an operation apparatus. The operation apparatus in this application includes a controller and a first operation unit, the controller is in signal connection with the first operation unit, the first operation unit includes a first memory and a first transistor, a drain of the first transistor is connected to a negative electrode of the first memory, and a source of the first transistor is grounded. The Hamming weight calculation method is performed by the controller. Specifically, 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 an input 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.
