摘要
数字滤波器和快速傅氏变换算法是数字信号处理的两大基石。在DSP芯片上实现数字滤波器算法的传统做法是用汇编语言编写软件来实现。用汇编语言编写的DSP程序具有最好的执行效率 ,但DSP汇编语言的编程效率较低。该文主要研究如何使用基于交互的方框仿真和自动代码生成快速原型的方法进行滤波器设计。实现了从顶层的系统仿真到底层的芯片算法的设计。
Digital filter and Fast Fourier Transform Algorithm is two big foundation stones of the Digital Signal Processing. On DSP chip, the traditional method that realizes the digital filter algorithm is to compile software with assembly language. It has the best efficiency, but cycle is lower. In this paper, research how to carry out the Algorithm of digital filter based on fast prototype. Have realized the design that goes to the chip algorithm of bottom from the system simulation of top layer. This method has shortened the development cycle of algorithm greatly.
