Effective implementation methods of FIR filters in FPGAbased signal processing systems

Abstract

Today’s modern FPGA devices and high speed digital to analog converters make it possible to use advanced direct synthesis technologies in semi-professional equipment. However this market segment is usually cost-sensitive, that’s why effective usage of available hardware resources is important. This paper analyzes implementation techniques of one of the most resourceconsuming building blocks – FIR filters, special attentions is paid to multiplierless approach. Proposed ways of improving existing methods using hardware resources available in the latest-generation FPGAs.
