  • Method, system and computer program product for digitally generating a function
    Patent number: 6807554
    Abstract: A method, system and computer program product for digitally generating a function, including a phase accumulator configured to receive a phase value and integrate the phase value to generate an accumulation result; an address generator configured to generate consecutive addresses based on the accumulation result; a storage device configured to initiative initial digital function values based on the consecutive addresses; a coefficient calculator configured to generate coefficients for a polynomial interpolation based on the initial digital function values; and an interpolator configured to generate a final digital function value corresponding to the phase value based on the accumulation result and the coeffcients.
