Abstract

The way to realize an arbitrary waveform generator with FPGA and DDS are discussed in this paper.The microcomputer is the master controller in this system,it can accomplish the disposal and control of the user interface.The FPGA integrate the periphery interface circuit,it can realized the function of Accumulator.The FPGA can export scanning when the microcomputer is writing to the RAM by use the dual port RAM,therefore the system is to become more rapid.The simulation results are given by using the Proteus and Matlab at the same time.
