| Abstract: | The characteristics of digital signal processor (DSP) are investigated from the viewpoint of design and application in the article. The characteristics distinguished from other processors are elaborated from the aspects of architecture, instruction set and processing unit. The developing situation of DSP is presented; the processes from single MAC unit and complex instruction to double MAC units and complex instructions, as well as to single instruction and multiple MAC units are reviewed. And it is indicated that the application of DSP has compelled it forward rapidly. At last, the trend of development of DSP is predicted: the multi-issued DSP, embedded DSP and hybrid DSP of computation and control are the future orientations of DSP. |
