New approach to hardware FIR filter implementation is described in this paper.Method includes the conversion to the frequency domain, as well as the principles of residue number systems and number-theoretic transforms.Parameterized RTL IP-core generators were implemented for both conventional and developed methods.These IP generators were used to implement different devices for different filter orders and input widths.Filters were synthesized, and resulting time and hardware evaluation allow one to consider the effectiveness of the method compared with the conventional realization of FIR filter.
