Design of Chirp Signal based on NIOS

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/Simulinlc/DSP Builder/ Quartus II. The generator can produce the chirp signal well which is verified by the Matlab/Simulink and Quartus II. 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.
