Abstract:
1. A method for processing data samples, the method comprising: storing, in a base function generator block, a plurality of different base functions, wherein each base function of the plurality of different base functions is a respective specified order derivative of a corresponding respective filter function; selecting in the base function generator block a base function from the plurality of different base functions; producing, by the base function generator block, an initial sequence of data values corresponding to the selected base function; producing, by a series of accumulator circuits, and based on the initial sequence of data values, a plurality of sequences of data values, wherein each accumulator circuit of the series of accumulator circuits comprises a data input and a data output, wherein the data output of each accumulator circuit, except the last accumulator circuit, is coupled to the data input of a successive adjacent accumulator circuit in the series of accumulator circuits; selecting a sequence of filter coefficient values from the plurality of sequences of data values, by selection circuitry coupled to the data output of each of the plurality of accumulator circuits, corresponding to a specified order integral of the selected based function, wherein the specified order of the integral of the selected base function matches the respective specified order of the derivative of the respective filter function corresponding to the selected base function; and modifying, by a processing element, respective values of one or more data samples of a data stream according to one or more filter coefficient values of the sequence of filter coefficient values.
