Design and Optimization of DDS Based on CORDIC in FPGA

This paper realizes DDS by using the CORDIC algorithm to calculate the value of trigonometric function, which is convenient to the FPGA implement.According to analysis of the traditional pipeline structure CORDIC algorithm, we present a new method of optimization that using different bits to save the anger value and amplitude value during iterations, and realize it in FPGA, which can reduce the FPGA resource.
