Hardware Implementation of CORDIC Algorithm
Anuvab Sahoo, Mamata Panigrahy · 2018
CORDIC algorithm provides an effective way of computing trigonometric and hyperbolic functions. This algorithm replaces multiplication operation through iterative addition and bit shifting action. This not only saves area but also improves the throughput. This paper reviews the basic CORDIC algorithm and implements folded word-serial and unfolded pipelined CORDIC architecture. These designs are implemented using Xilinx Artix-7 FPGA. Hardware utilization and speed of operation are tabulated for both designs. Accuracy for 16 bit precision CORDIC design is noted by comparing the same with Matlab simulation result.
