Abstract
A multiply-accumulate device comprises a digital multiplication circuit and a mixed signal adder. The digital multiplication circuit is configured to input L m-bit multipliers and L m-bit multiplicands and configured to generate N one-bit multiplication outputs, each one-bit multiplication output corresponding to a result of a multiplication of one bit of one of the L m-bit multipliers and one bit of one of the L m-bit multiplicands. The mixed signal adder comprises one or more stages, at least one stage configured to input the N one-bit multiplication outputs, each stage comprising one or more inner product summation circuits; and a digital reduction stage coupled to an output of a last stage of the one or more stages and configured to generate an output of the multiply-accumulate device based on the L m-bit multipliers and the L m-bit multiplicands.
