中文摘要：

数字信号控制器具有数字信号处理器和微控制器的优点,在现代自动控制、数据采集系统中占据着重要的地位,TMS320F28335作为目前最主流的数字信号控制器,在实际工程中被广泛的使用。目前该处理器存在着程序设计周期长,程序设计过程复杂等问题。采用模型化设计的DSP嵌入式系统程序开发方法能很好地解决这个问题。以设计一个基于DSP的音频数据采集系统为例,通过将CCS软件和Matlab/Simulink进行有机的结合,对模型进行图形化界面配置,最终实现目标处理器程序代码的自动生成、下载、调试和运行,从而快速地实现音频信号数据采集系统的设计。

英文摘要：

The digital signal controller has the advantages from digital signal processor and microcontroller,which has played the important role in modern automatic control and data acquisition system. TMS320F28335 as the mainstream digital signal controller is widely used in practical engineering. Currently,this processor has the problems of long period program design and complicated program design process. The program development method of DSP embedded system with modeling design can solve these problems better. Taking design a DSP-based audio signal acquisition system as an instance,the graphic interface of the model is configured by combining CCS software with Matlab/Simulink greatly. The automatic generation,downloading,debugging and operation of the program codes in the target processor are realized,and the design of this audio signal acquisition system can be implemented fast.
