  • Programmable canonic signed digit filter chip
    Patent number: 5262974
    Abstract: A programmable canonic signed digit (CSD) filter is provided which employs programmable CSD multipliers. The filter receives a digital input signal and includes a tapped delay line for providing a delay between the input samples. The filter advantageously employs a plurality of programmable CSD multipliers which receive programmable input filter coefficients and perform multiplication of the coefficient with the delayed input signal. Summation hardware is further included for summing the outputs of the plurality of multipliers to provide the filter output therefrom.
