摘　　要：数字信号处理器(DSP)是专门针对数字信号处理运算而设计的微处理器芯片。本文在介绍DSP算法特点的基础上,指出了DSP的基本结构组成以及当前主流DSP的两种典型体系结构。分析了这两种结构各自的优缺点,最后根据DSP应用领域的新情况以及微处理器体系结构的发展,对DSP结构的发展提出了一些看法。Digital signal processor (DSP) is the microprocessor specially by digital signal processing ( DSP )algorithm.The character of DSP algorithm is presented in the paper, and basic architecture organization of DSP and the two representative architectures of the moder, mainstream DSP are directed, then point out the advantage and disadvantage of each architecture.According to new circumstances of application area of DSP and the development of microprocessor architecture, new trends of DSP architecture is indicated in the paper finally.
