Abstract
A method and apparatus may be used to evaluate a polynomial by initializing a multiply and accumulate feedback apparatus () comprising a multiplier stage () having an output coupled to an input of an accumulator stage () having an accumulator feedback output () selectively coupled to an input of the multiplier stage over a plurality of clock cycles; iteratively calculating a final working loop variable z over an additional plurality of clock cycles; multiplying the final working loop variable z and a complex input vector x to compute a final multiplier value; and adding a least significant complex polynomial coefficient to the final multiplier value using the multiplier stage of the multiply and accumulate feedback apparatus to yield a result of the polynomial evaluation.
