摘要：

In order to achieve the goal of higher accuracy of DDS, In this paper, we will concentrate to modify and improve pipelined accumulator and the ROM lookup table which is based on the Cordic algorithm on the base of traditional DDS. And compared with the advantages and disadvantages of traditional algorithm, experiments have proofed that the Cordic algorithm can solve the problems of disorder, decentralization, big truncation error and instability of the traditional DDS output signal and it can also save the hardware resources up to 30%. It has obvious advantages showed on the speed, accuracy and hardware resources of the system.
