Abstract
A multiplier-accumulator includes: a plurality of exclusive negative OR (XNOR) gates provided along one or more input lines and configured to receive signals corresponding to an input bit sequence and a weight bit sequence corresponding to each of the one or more input lines and to output partial product results between the input bit sequence and the weight bit sequence; an encoder configured to apply, to the plurality of XNOR gates, a signal corresponding to a sequence in which a logical value of a most significant bit (MSB) is converted from an original sequence expressed in 2's complement of a corresponding sequence for either one or both of the input bit sequence and the weight bit sequence; and an outputter configured to generate an output in which a correction value is applied to operation results in which the partial product results output from the plurality of XNOR gates are summed.
