Abstract (en)
[origin: WO2021122261A1] Method, implemented by computer, for coding a digital signal quantified on a given number Nd of bits and intended to be processed by a digital computing system, the signal being coded on a predetermined number Np of bits that is strictly smaller than Nd, the method comprising the steps of: - receiving (101) a digital signal composed of a plurality of samples; - decomposing (102) each sample into a sum of k maximum values that are equal to 2Np-1 and a residual value, with k a positive or zero integer; - successively transmitting (103) the values obtained after decomposition to an integration unit in order to perform a MAC operation between the sample and a weighting coefficient.
