摘要
数字信号处理器芯片从1980年开始为人们所使用,它引发了工业设计的革命。在当今的数字化时代背景下,DSP己成为通信、计算机和电子产品等领域的基础器件。DSP处理速度快、低功耗、体积小的特点为产品的研制开辟了一条新的道路。
最早的信号发生器,多是用模拟电路设计的,这使信号发生器的性能受到了很多的限制。随着大规模集成电路的应用,信号发生器也开始数字化,但是大部分都用硬件设计很少有用软件来设计,本设计是尝试用DSP处理器芯片通过软件来实现信号发生器和频谱分析。
本论文详细介绍了通过软件编程所设计的信号发生器的设计构想,算法原理以及程序设计等,并阐述了基于TMS32OVC54O2 DSP芯片实现的信号发生器的设计原理、过程和实现方法以及运行得到的结果。S图形观察器观察利用信号发生器设计产生的正弦波,方波,三角波等基本图形以及心电信号等较为复杂的波形。本设计可以产生正弦波,三角波,方波等基本波形并进行频谱分析等操作,也可以产生较为复杂的波形并进行频谱分析等操作,例如产生心电信号。这种设计的优点是开发周期短,可移植性好。

ABSTRACT
DSP (Digital Signal Processing) chips were first used in 1980, and since then they brought a new revolution in industrial design field. DSP has e a ment of the product munication, computer, electronic and so on. The high processing speed, low power consumption and small volume provide a new way for the product.
The signal generator was constructed by analog electronic before 1980,which made the faction limited .Now with the development of the maelstrom, the signal generator switch to digital. The construction plicated. The most of them is constructed by digital hardware, there are litle designed with software .This design is atempt to design it and performance the spectrum analysis with DSP by software.
This brochure has introduced the algorithm principle and the program design of the wave form which is designed by software programming in detail,and explained the principle,course,implementation method and result received based on the TMS320VC5402 observe the sine wave,triangular wave,square wave and the electrocardiograph which is plex signal generator designed in this design,can produce sine wave,triangular wave,square wave which is basic wave form;it also can plicated wave form,such as electrocardiograph;it can carry on frequency spectrum to analyse, strongpoint of this design can shorten the period of design time and stronger adaptability.
