Hardware friendly schemes to implement exponential linear phase FIR filters

A family of exponential linear phase FIR filters was previously proposed. This work investigates various hardware schemes that can be used to implement fast exponential linear phase FIR Filters. The investigated schemes are the alternative base implementation for filters with integer bases and a recursive implementation for filters with fixed-point bases. Both schemes are described in hardware description language, synthesized, and simulated. The results show that both implementations can achieve high operating frequencies with a reasonable hardware size.
