Design and Implementation of DDS Function Generator Based on FPGA
Luo Ke-xue · Machine Building & Automation · 2010
In this paper,the design considerations of a DDS(Direct Digital Synthesizer) function generator with DSP Builder,including the method of changing frequency,amplitude and phase of output signal,are introduced.This system is mainly controlled by FPGA of Alter,and it is also assisted by micro-processor C8051F340.The results of software simulation of the system are given and hardware verification of the whole system is completed.The results prove that the design is correct,and show that the use of DSP Builder is simpler and faster to implement the DDS function generator.
