Design and Implementation of Chirp Function Based on NCO IP core

This design analyses the character of Chirp function in the time and frequency domain zone.And after analyzing the input/output feature of the NCO IP core.The different output frequency by writing different controlling words which can be determined from the MegaCore environment.The FPGA′s running situation by oscillograph to inspect and verify feature of the design is detected.The conclusion that this design can get the Chirp′s function perfectly.
