摘　　要：近年来,随着信息化的进程和计算机科学与技术、信号处理理论与方法等的迅速发展,在智能控制方面对实时性和精度的要求越来越高,而且需要处理的数据量也越来越大,显然低档单片机已不能再满足其在智能控制方面的要求。本文从性能、价格等方面对单片机和DSP器件进行了比较,并在此基础上以TT的TMS320C2XX系列DSP器件为例,探讨了DSP器件取代单片机的可行性。Recent years have witnessed the rapid development of information industry, computer science and technology, and theories and methods of signal - disposal, etc. Requirements in accuracy and timeliness of intelligence control have been becoming stricter, the same with datas needed to be delt with. Obviously, low - end SCM (Single - Chip - Microcomputer) can not meet its requirements in intelligence control. This article is centered on a comparison between SCM and DSP from price and performance, and take DSP of TMS320C2XX series by TI (Texas Instruments) as an example to explore the feasibility of replacing SCM with DSP.
