第十讲 数字信号处理与数字信号处理器(DSP)

Digital signal processing and processors

文章简要介绍了“数字信号处理”与“数字信号处理器(DSP)”的发展历史.在数字信号处理的应用中,实时实现是非常重要的,而DSP在实时处理中,扮演了一个重要的角色.文章中还介绍了DSP在实际应用中的一些关键技术,例如DSP的种类和选型,DSP的开发工具,实时软件的开发过程等.最后,还介绍了一些DSP的应用实例,如语音编码器,视频电话和视频会议系统。

The history of digital signal processing and the digital signal processor （DSP） is reviewed. As is wen known, real -time implementation is crucial in the applications of digital signal processing in which the DSP plays an important role. Certain key techniques, such as the types and type selection of DSPs, their development equipment, real -time software development and so on are then described. Finally, some practical applications such as speech coding hardware, video telephone and video conference systems, DSP parallel processing systems for sonar and radar are also described.
