Design of DDS Circuit Using Improved CORDIC Algorithm
Xue Zhong-jie · 2010
CORDIC algorithm is widely used in direct digital frequency synthesizer(DDS)and some other digital communication circuits due to its high speed and high accuracy.An improved CORDIC algorithm was proposed based on conventional CORDIC algorithm.Using the new algorithm,ROM space required in the traditional algorithm was reduced,and operation speed was improved.The proposed DDS circuit was implemented on FPGA of Cyclone II-EP2C5AF256A7 by Altera for verification,which saved resource.
