Abstract
An arithmetic device includes a multiplying-accumulating (MAC) operator and an activation function (AF) circuit. The MAC operator performs a MAC arithmetic operation for weight data and vector data to generate an arithmetic result signal. The AF circuit extracts a first bit group and a second bit group from the arithmetic result signal. In addition, the AF circuit generates an input distribution signal based on the first bit group and the second bit group. Moreover, the AF circuit selects and outputs an output distribution signal that corresponds to the input distribution signal based on an activation function.
