Abstract:
A digital filter having a plurality of filter cells for generating processed data, each of the filter cells comprising:a plurality of coefficient registers for circulating a plurality of coefficient values corresponding to a plurality of coefficients, said plurality of coefficient registers outputting each of the plurality of coefficients once during a predetermined time period;one or more data registers for circulating a data value for a time period which is at least as long as the predetermined time period such that said one or more data registers outputs the data value each time that said plurality of coefficient registers outputs a different one of the plurality of coefficients is output;an output for supplying said output data value to a following filter cell in said plurality of filter cells; anda circuit for receiving each output data value and each output coefficient and for generating processed data by processing each output data value with each output coefficient.
