摘要
本文从设计和应用的角度分析了数字信号处理器 (DSP)的特点 ,详细地从结构、指令集和运算单元方面阐述了DSP区别于其它处理器的特点 ;介绍了DSP的发展概况 ,从复杂指令单个乘法累加运算单元发展到复杂指令两个运算单元 ,又发展到简单指令多个运算单元 ,并指出是应用推动了DSP的飞速发展 ;最后 ,对DSP的发展作了预测 ,DSP将在多发射。
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.
