基于Matlab的DSP实验设计

The Design of DSP Experiment Based on Matlab

本文以开发三相SPWM调制系统为例,详细阐述了基于Matlab/Simulink的DSP实验设计与实现。传统的DSP代码开发周期较长,效率不高。Matlab公司的Embedded Target for TI DSP可解决上述问题,用户通过使用该模块,不仅可以进行电路的系统级仿真,还可编译生成相应的C语言代码,进行算法的探索与设计思路的验证。通过Matlab先仿真后直接生成DSP代码进行实验的方式,使学生加深对DSP的认识,并能很快独立用DSP进行开发。

A DSP SPWM modulation system model is built in the Simulink platform with the use of Simulink modules in Matlab. Traditional way for DSP code developed has a long cycle and low efficiency drawback. Embedded Target for TI DSP of MathWorks can solve the problems. Through this library, the users not only can complete the simulation, but also can generate C code. The users also can verify the correctness of the algorithm. Through the auto generation of DSP code by Matlab/Simulink modules, make students to deepen the understanding of the DSP, and develop DSP code quickly and independently.
