Abstract
The present disclosure relates to circuitry for performing a multiply-accumulate (MAC) operation. The circuitry comprises a first multiplexer having a plurality of inputs for receiving a plurality of unary-coded input signals representing operands of the MAC operation and an output for outputting a multiplexer output signal representing a result of the MAC operation and a first vector quantizer configured to receive a plurality of weighting signals, each representing a proportion of a computation time period for which a respective one of the unary-coded input signals should be selected by the multiplexer and to output a first selector signal to the multiplexer to cause the multiplexer to select each of the input signals in accordance with the plurality of weighting signals.
