Implementation of FIR filter as per DO-254 compliance

摘要

Implementation of filter needs mainly three basic building blocks as multiplier, adder and signal delay. If a filter has to be speed means it should have high speed basic building block i.e. multiplier and adder blocks should be very high speed. The paper presents a proposed digital FIR filter which is delay efficient and area efficient. The improvement of proposed Direct Form FIR filter in delay is of 11% and 26% of area has been decreased. The design has been implemented in Verilog according to the DO-254 compliance guidelines, simulated in industrial standard simulator Questasim and synthesized using Precision synthesis RTL plus and Xilinx ISE. DO-254 compliance is done using HDL Designer tool suite.
