Abstract: T his paper described an original design project of DDS device based on the SOPC techno-
logy , particularly discussed the principle of DDS and the design course of SOPC. This design inte-
grated the DDS module and the MCU module on a single FPGA chip. So the performance such as
integration, stability and expansibility improved much.
