基于TMS320VC5402 DSP芯片的信号发生器的设计 摘 要 信号发生器发展到今天，在电子测试、电子设计、模拟仿真中，扮演着一个重要的角色，极大加快了电子测试与设计工作中的效率，在电子技术和信号仿真应用中已发挥了巨大的作用The design of the signal generator based on TMS320C5402 DSP CMOS CHIP ABSTRACT Signal generator which is developed now 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 design 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 onTMS320VC5402 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. The core of this system TMS320VC5402 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 TMS320VC5402DSP C chip and D/A conversion chip TLC7528.DSP chip produce waves and D/A conversion chip is used change digital signals to analog signals. Based on these hardware, we use software to carry out sawtooh wave, triangle wave, square wave, trapezia wave and 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.
