摘　　要：数字信号处理器(DSP)是一种具有特殊结构的微处理器,特别适合于进行数字信号处理运算,它是当今发展最为迅速和前景最为可观的技术之一。自从20世纪80年代第一片DSP芯片诞生至今,其性能得到了极大的提高,应用领域取得了不断的拓展。目前它已经成为通信、计算机、网络、工业控制以及家用电器等电子产品不可或缺的基础器件,尤其在通信领域,数字信号处理器以其实时快速地实现各种数字信号处理算法的优点得到了广泛的应用。文章结合DSP芯片的特点,介绍了它在语音压缩和软件无线电领域中的应用,以及在进行系统设计时, DSP器件的选择。DSP is a kind of microprocessors, which has a special structure, so it is very fit for digital signal processing. It is one of the most popular and prospective techniques. Since the early of 1980′s the first DSP chip was invented, until now its capability has got a great development, and its application fields have continuously extended. At present, DSP has been a basic instrument in the communication field, computer, network, industry control, home facility and so on. Especially, digital signal processor has been applied in communication here and there, because of its ability of fast processing kinds of algorithm in digital signal processing on real time. In this paper, based on the character of DSP, the application on voice compressing and software radio technique and the chip selection of DSP during system design are introduced.
