摘要
基于直接数字合成器(DDS)技术设计的任意波形发生器中,ROM查找表是DDS模块的一个重要环节,主要用于存储系统的波形数据。介绍使用C语言、Matlab和DSP Builder三种方法生成正弦波、三角波、锯齿波和方波的查找表初始化波形数据,并对每一种方法的程序设计、参数设置以及波形仿真都作了详细说明,所有波形数据均在GW48 SOPC开发系统中测试通过。
In the arbitrary waveform generator based on DDS,ROM LUT is an important element of the DDS module,which is used to store waveform data of the system.In the paper,using three methods,including C language,Matlab and DSP Builder,producing the arbitrary waveform initialization data of the sine wave,the triangular wave,the saw-tooth wave and the square-wave.Programming,parameter setting and waveform simulation are described to every method detailedly.All waveform data are verified by GW48-SOPC development system.
