| Abstract: | In order to meet the demands of data processing speed,a kind of control system based on FPGA+DDS was designed.In the paper,hardware of the control system was designed based on the characteristic of AD9910 and the design of the power,ground and filter was described particularly.The software control flow of FPGA was designed and the correlative software examples were given.It described the setting of each control-register and require of timing of DDS AD9910 in detail.At last,the test result was given.The result proves that the wave is high quality and good effct.It will be with realistic meaning and usable value in the design and implement of frequency synthesis source. |
