A pipelining direct digital synthesis(DDS) architecture based on basic principles of CORDIC algorithm is proposed in this paper to replace the traditional method of ROM look-up table.A full cycle of the trigonometric function calculations was achieved with this algorithm by pre-processing of input angles and post-processing of iterated results.The design was described by Verilog language,compiled by Quartus Ⅱ 9.0 and simulated by Modelsim-Altera 6.4.The results indicate that the algorithm has advantages of large calculation angle range,high speed operation and low resource.
