Filter Hardware Cost Reduction by Means of Error Feedback
Original language description
A simple method to reduce the hardware cost (silicon area) of the biquadratic section implementation by means of error feedback (EF) is described. The optimization method utilizes the fact that the filter with an EF is more resistant to roundoff noise than a filter without it. An iterative method is used to reduce the occupied silicon area. Results show it is possible to spare up to 22% of the occupied silicon area. Our findings are valid for FPGA as well as ASIC implementation of the IIR filters. Ourmethod has an advantage in using a standard and already verified filtering IP core which results in design time reduction.
