Approved for public release; distribution is unlimited === To implement an IIR notch filter is theoretically feasible but not technically verified or validated. Two methods often used to speed up a computation are multiprocessing and pipelining. In designing a notch filter the pipelining technique is the natural choice to speed up its processing speed. To have a rapid prototype design we may employ the silicon compiler techniques and explore numerous design variations before sending for fabrication. This paper will report the alternative pipelined design of IIR notch filters. We will present the problem, explain the methodologies used in our investigation, analyze the results, and discuss the findings. We first summarize various fixed-point designs for the pipeline building component, the multiplier-adder pair. We then present the design considerations about the system integration. Various parameters are investigated in our research: pipelined stages, timing, silicon area. Additionally, the experiences and difficulties of using timing verifiers that are built in the silicon compiler will be discussed as well.
