摘 要
本篇论文叙述了IIR数字滤波器的设计原理及其在DSP上的实现思路，并对用DSP实现IIR数字滤波的方法进行了分析。用MATLAB计算出IIR数字滤波器的系数，考虑到溢出问题，采用级联的形式对滤波器进行分解，最后在TMS320VC5416 DSP上得以实现，并通过CCS(come composer studio)的输入输出功能和RTDX(real-time data exchange)的功能保证实现结果和仿真结果的一致性。 关键词： IIR数字 滤波器 DSP 算法
Abstract: this paper narrated the IIR digit filter's principle of design and realizes the mentality on DSP, and to used DSP to realize the IIR digital filtering's method to carry on the analysis. Calculates the IIR digit filter's coefficient with MATLAB, considered the overflow question, uses the cascade the form to carry on the decomposition to the filter, finally can realize on TMS320VC5416 DSP, and through CCS (come composer studio) input output function and RTDX (real-time data exchange) the function guaranteed that realizes the result and the simulation result uniformity.
key word: IIR digital filter DSP algorithm
