A two-dimensional logarithmic number system (2DLNS)-based Finite Impulse Response (FIR) filter design

摘要

The ever increasing demand for low power DSP applications has directed researchers to contemplate a variety of potential approaches in different contexts. In this regard, using some alternative number systems, which inherently are capable of reducing the hardware complexity, have been propounded. In this work, a 2DLNS-based platform for multiplication intensive DSP applications is presented. Implementing an FIR filter structure on this basis shows outstanding privilege to its binary counterpart in terms of VLSI area and power consumption.
