This paper analyzes the function of chirp. A design solution based on SOPC technology chirp signal put forward after the function had been studied both the hardware design and implement method. The chirp signal generator based on SOPC is designed according to the design process of Matlab/Simulink/DSP Builder/ QuartusII. The generator can produce the chirp signal well which is verified by the Matlab/Simulink and QuartusII. The starting frequency, bandwidth, and frequency resolution of chirp signal can be revamped by utilizing SOPC technology. This method is easier to implement since it is simple to design, easy to modify, low cost, no programming.

Setting Parameters

A phase shift signal generator which has high precision and whose phase can be easily and digitally controlled is designed through utilizing DDS technology. A method which can replace complicated hardware description language programming through calling modules and setting parameters is proposed. The designed phase shift signal generator passes waveform simulation under Simulink and SignalTap Ⅱcertification, and the results obtained on the FPGA board are correct. The DSP Builder is utilized to design the phase shift signal generator, which reduces the difficulty of the design and shortens the design time.
