Xiaoli Zhou · Computer Development & Applications · 2012
This paper uses the Cyclone series of EP1C3T144C8 device to complete the circuit design,description of compilation,simulation,comprehensiveness and other major processes of DDS Besides.It uses the Quartus II platform of ALTERA company and bases on the principle of direct digital frequency synthesizer to design language of VHDL.Also,through the field programmable gates array FPGA to find table,it realizes a 32 bit simple direct digital synthesizer scheme that the frequency and phase of this mode are controllable.Last,simulation and hardware validation test the correctness of the design.
