Field-programmable logic (FPL) is on the verge of revolutionizing digital signal processing (DSP) in the manner that programmable DSP microprocessors did nearly two decades ago. While FPL densities and performance have steadily improved to the point where some DSP solutions can be integrated into a single FPL chip, they still have limited the use in high-precision high-bandwidth applications. In this paper it is shown that alternative implementation strategies can be found which overcome the precision/bandwidth barrier. The design of Daubechies length 4 and 8 filter is presented to compare FPL and programmable DSP solutions.
