The implementation of FIR low-pass filter based on FPGA and DA

Abstract

The DA(distributed algorithm) is the key of FIR filter implementation based on FPGA, compared with the traditional multiply-add structure, DA has the characteristics of parallel data processing and efficient operation. This paper shows that the design method of a 16 order FI R filter based on FPGA is studied, using VHDL language. Simulation experiments and time series analysis are carried out in EDA platform of ALTERA, the design is verified by being downloaded to the EPF10K10LC84-3 FPGA chip. The design of FPGA has practical applications in digital signal processing; it has certain directive significance to the reform of electronic technology practice teaching.
