摘　　要：可编程DSP(digital signal processor)是一种能够快速进行数字信号处理的特殊微处理器,而数字滤波器是DSP的基本应用之一.通过介绍利用DSP技术,采用线性缓冲区和带移位双操作寻址的方法实现FIR滤波器的设计.目前所见文献,多数为滤波器的模型设计,所得结果只是在MATLAB等实验环境下模拟仿真完成,带有很大的局限性,而FIR数字滤波器可在TMS320C5402 DSK系统板上实现,保证了仿真和实现结果的一致性.Programmable digital signal processor is a kind of special microprocessor which can do digital signal processing rapidly. Digital filter is one of its basic application. This text introduced a method which makes use of DSP technique, the adoption of linear buffer with the method which takes to move bits and to look for address with dual operations to carry out a FIR filter＇s design. All the documents at the present, in which there are many designs of filter＇s model. Only using the MATLAB software to carry on imitating real, in which there is much limitation. The FIR filter can be carried out at the TMS320C5402 DSK system plank and it promises to the consistency between imitating real and the result of carrying out.
