Abstract
A multiplication-and-accumulation (MAC) circuit includes a MAC operator and a data input circuit. The MAC operator selectively performs a MAC arithmetic operation of weight data and vector data or an element-wise multiplication (EWM) arithmetic operation of the weight data and constant data. The data input circuit provides the MAC operator with the weight data and the vector data when the MAC operator performs the MAC arithmetic operation and provides the MAC operator with the weight data and the constant data when the MAC operator performs the EWM arithmetic operation.
