tailieunhanh - Filter design based on DSP builder

Presents a method to realize FIR filter based on DSP Builder, FIR design using a relatively independent function of circuit module and subsystems in the design, it can easily realize the filtering function of FIR, simplified the design, modular design method greatly shortens the development cycle, make the system have been optimized in the chip area and timing analysis etc. | Send Orders for Reprints to reprints@ The Open Electrical Electronic Engineering Journal 2015 9 15-21 15 Open Access Filter Design Based on DSP Builder Ding Ji-feng Xu Shuang Zhang Jun-xing and Yang Ya-ning Information Communication Engineering Dalian Nationalities University Dalian Liaoning 116600 China Abstract Presents a method to realize FIR filter based on DSP Builder FIR design using a relatively independent function of circuit module and subsystems in the design it can easily realize the filtering function of FIR simplified the design modular design method greatly shortens the development cycle make the system have been optimized in the chip area and timing analysis etc. Experimental results show that the filtering performance of the filter is good and completely suitable for use in practical engineering in various signal processing. Keywords DSP Builder FIR signal processing time series analysis. 1. INTRODUCTION Digital filter can be divided into two categories according to the time domain characteristics of unit impulse response function Infinite Impulse Response IIR filter and Finite Impulse Response FIR filter. Compared with the IIR filter FIR filter has the advantages of exact linear phase easily implemented in hardware and system stability and are widely used in digital audio image processing satellite navigation and military communication fields 1-3 . At present there are many kinds of main implementation method of FIR digital filter. The design method based on DSP chip adopt a unique internal hardware structure to realize the filtering algorithm it not only need instruction programming but also debugging online simulation real-time on DSP hardware so the development process is very complex 4 the design method based on MATLAB and DSP hardware aided design using MATLAB to extracting the filter coefficients but needed to write special instruction code for digital signal processing on DSP so dependency on hardware poor portability the .
