ABSTRACT: This
paper presents the design and implementation of a low-pass, high-pass and a hand-pass
Finite Impulse Response (FIR) Filter using SPARTAN-6 Field Programmable Gate
Array (FPGA) device. The filter performance is tested using Filter Design and
Analysis (FDA) and FIR tools from Mathworks. The FDA Tool is used to define the
filter order and coefficients, and the FIR tool is used for Simulink simulation.
The FPGA implementation is carried out using Spartan-6 LX75T-3FGG676C for
different filter specifications and simulated with the help of Xilinx ISE
(Integrated Software Environment). System Generator ISE design suit 14.6i is
used in synthesizing and co-simulation for FPGA filter output verification.
Finally, comparison is done between the results obtained from the software
simulations and those from FPGA using hardware co-simulation. The simulation
waveforms and synthesis reports verify the parallel implementation of FPGA
which proves its effectiveness in terms of speed, resource usage and power
consumption.
