该系统的核心芯片TMS320VC5416 DSP是TI公司生产的16位定点处理芯片，它有运算速度快、具有可编程特性、接口灵活和外围电路丰富等特点。选择该芯片作为设计信号发生器的核心芯片，能够提高信号发生器所产生信号的频率，使信号发生器有更加广泛的应用。设计的硬件部分是由DSP芯片和D/A转换芯片TLC7528组成， TMS320C5416 DSP通过D/A输出正弦信号，正弦信号通过DSP应用软件给出，可通过键盘改变正弦信号幅度、频率、相位，并通过LCD显示正弦信号的参数。在以上硬件的基础上，通过软件编程来实现正弦波波形。
通过软件调试后，所要求的波形都能按要求实现。由于设计的时间短等原因，本次设计只是原理性的设计，要达到实用，还有许多的工作要做。由于经验不足，在设计中还有许多不足之处，需要进一步改进。

The design of the signal generator
based on TMS320C5416 DSP CMOS CHIP
ABSTRACT
Along with the development of signal generator, it is playing an important role in the electron test、electron design、simulate emulate、communication engineering and so on, signal generator is used very comprehensive and expedite the efficiency of the electron test and electron design,signal generator exert immense effect in the electron technology and the signal emulate.This text mainly introduce the design of the signal generator based onTMS320VC5416 DSP CMOS chip. This is a signal generator system
which is make DSP as its core ,this system with configuration simpleness agility, anti-jamming capability better, frequency higher, application abroad and so on.

洗瓶The core of this system TMS320VC5416 DSP CMOS chip is made by TI company which has 16 bit pointing dispose chip, it has operation rate high, having programme characteristic, interface agility and periphery circuit abundance characteristic. Choosing this chip as the core of the signal generator, it could enhance the frequency of the signal generator and make the signal generator used more widely. The hardware of this design is made by TMS320VC5416DSP CMOS chip and D/A conversion chip TLC7528.DSP chip produce waves and D/A conversion chip is used change digital signals to analog signals. The TMS320 C5416 DSP CMOS which can product sine signal by software pass the D/A exportation sine signal. Keyboard change sine signal range, frequency, mutually, and pass the parameter of the LCD manifestation sine signal. Based on these hardware, we use software to carry out sine wave.
After soft ware debugging and all the waves could be actualized as we need. Because of
the time is short, this design is only elements design, if we want use it in life, we need do much more. Because experience lacking, the design has much shortage, needing more change.

前 言
信号发生器，主要作为仿真信号，广泛应用于电力电子、电子设计、环保、机械运动、航空航天、国防、生物医疗、新型材料等各个领域。随着技术的进步，各领域对信号发生器的要求也越来越高，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，由于用硬件设计的电路存在波形质量差，控制难，可调范围小，电路复杂和体积大等缺点，所以一旦工作需求功能有增加，则电路复杂程度会大大增加。
