Abstract
Field Programmable Gate Arrays (FPGA) have become viables alternatives to
implementation of high speed semiconductor technology. It is used in many
application such as in digital signal processing (DSP). The FPGA current device
such as XILINX have power and capacity to implement a FIR filter with high
performance and specifICation. In this thesis, the Digital Decimation FIR Low Pass
Filter with Linear Phase for Low Frequency (DDFIR) application has been designed
to perform the specifications of the sonar system applications. The Remez Exchange
Algorithm is used to determine the filter order and to calculate the filter coefficient by
using the very simple MATLAB script. The modified direct form structure for linear
phase filter hardware realizes this filter with multiplier-free and minimum number of
delays and adders. The hardware implementation has been made in Schematic
Capture to realize it in FPGA. The hardware simulation is introduced and its
performance is verified by investigated the structural timing simulation which is
available in the XILINX FOUNDATION 2.1i Tools. The result of simulation shows this
filter system achieveds the maximum frequency up to 19.92 MHz. This filter will be
downloaded into a FPGA XILINX XC4013XLA.
