Comparative Analysis and Efficient VLSI Implementation of FIR Filter

Mahesh Kadam, Kishor Sawarkar, Sudhakar Mande

In this paper, we present suitable design optimization for area-delay efficient implementation of finite impulse response (FIR) filter on Field Programmable Gate Array (FPGA). Architectural optimization done in MATLAB/Simulink environment, Hardware description language (HDL) netlist produced by System Generator enables emulation on FPGA and also serves as design entry for chip realization. The design of digital filter characterized by minimum critical path and latency, low cost and reduced complexity. Considering above parameters different architectures are implemented such as transpose-form, pipelined filter and parallel processing. Result shows comparison for maximum frequency, resource utilization and reduced latency
