基于TMS320VC33的多功能DSP实验系统

Multifunctional Experimental System Based on TMS320VC33 DSP

随着数字信号处理课程的改革,增加了DSP系统的设计和开发等一系列实践类课程。本文给出了一种基于TM S320VC 33的DSP实验系统,该系统具有信号发送、灵活通信、信号分析、DSP与PC机间的互控以及仿真、脱机运行等多项功能,非常适合DSP芯片应用研究和实验项目开发。本文首先介绍了该系统的特点及硬件组成,随后具体描述了实验系统可实现的功能,并进一步讨论了在本系统基础上所开设的一系列实验内容,最后给出了示例实验及结果。目前,该系统已应用到研究生的DSP实验教学中。

The experimental course of design and development of DSP system is appended during the teaching reform of Digital Signal Processing. An experimental system based on TMS320VC33 DSP is presented, which is provided with various functions such as sending different signals, flexible communications, signal analysis, mutual control between DSP and PC along with simulation and off-fline tuning, adapting to the study of DSP application and the development of experimental projects. Its characteristics and hardware constitution are introduced, functions of the system are especially described in detail, and the contents of experiments based on the system are presented furthermore, an experiment for demonstration and its result are given at last. At present, the experimental system has been applied in the DSP teaching successfully.
