DSP(数字信号处理器)被誉为信息通信产业革命的旗手,本文将 就专为数字处理信号而开发的DSP作一简单介绍:DSP的过去,DSP与MPU的不同点,多媒体应用和今后发展前景。DSP的发展历程 在DSP出现之前,数字信号处理是利用大型计算机进行运算和模拟的。进入七十年代以后,出现了要求开发实时运算数字信号并可以装入产品中的廉价集成电路的呼声。1982年,美国德州仪器(TI)公司发表采用改进型哈佛结
DSP (Digital Signal Processor) Known as the standard-bearer of the information and communication industry revolution, this article will give a brief introduction to the DSP developed specifically for digital signal processing: the past of DSP, the difference between DSP and MPU, multimedia applications and future development prospect. The history of DSP Prior to the advent of DSP, digital signal processing is the use of large computers for computing and simulation. Since the 1970s, there has been a call for the development of inexpensive integrated circuits that can be used to develop real-time operational digital signals that can be loaded into products. In 1982, the United States Texas Instruments (TI) announced the use of improved Harvard junction
