This paper presents design and implementation of 3rd
order low pass digital FIR filter using pipelining retiming
technique. Aim of this paper is to apply pipelining retiming
technique on low pass digital FIR filter and compare with the
existing second order retimed FIR filter and third order
broadcast, non-broadcast low pass FIR filter. MATLAB FDA tool
is used to calculate digital FIR filter coefficients. Hamming and
Kaiser window methods are used to find out the coefficients of the
FIR filter. Broadcast and non broadcast third order low pass FIR
filter architectures are used for pipelining retiming .Cutset and
feed forward pipelining retiming techniques are used to retime the
third order low pass digital FIR filter. We design our algorithm in
VHDL and implemented on Xilinx Vivado xc7a35tcpg261-1. Area
(LUT), speed and power are calculated using Xilinx Vivado
2015.2 tool. Synthesis and simulation results are discussed in this
paper. Speed and area (LUT) of proposed third order low pass FIR
filter is improved in comparison with existing designs.
