Design and Implementation of an Efficient Modified CORDIC Algorithm
Yuan Xue, Zhongsong Ma · 2019
Coordinate Rotation Digital Computer (CORDIC) algorithm has greatly improved the efficiency of the hardware implementation of digital signal processing algorithms and other mathematical operations. While there exist quite a lot of redundant iterations in the Conventional CORDIC algorithm, this paper proposes a novel efficient modified CORDIC algorithm combining the Conventional CORDIC algorithm with the VSF CORDIC algorithm. And this new method has already been simulated and implemented on Cyclone IV FPGA. The results show that the number of iterations has been obviously reduced while the hardware resource consumption is also decreased to some extent.
