Square-Root Solution and FPGA Implementation based on CORDIC Algorithm
Deng Qiang · Communications technology · 2013
The solution of square root,as a kind of basic mathematical operations,is wildly used in engineering project.However,the implementation of square-root solution in FPGA is fairly complex,and it is necessary to study the efficient implementation.Experiment indicates that with CORDIC structure for computing the hyperbolic functions,the solution of square root could be efficiently realized.This paper describes CORDIC algorithm and its application in square-root solution,and then gives designs of the two square-root operation architectures suitable for the FPGA implementation,including parallel structure and bit serial structure,and finally compares the advantage and disadvantage of between this tow structure and analyzes the simulation results.
