Comparison of CORDIC and Modified CORDIC II Algorithm

Abstract: CORDIC algorithm is also known as digit by digit method. It is a special purpose digital computer for real time application .This is a unique computational technique which is suitable for trigonometric , square root ,Logarithm, Exponential function .CORDIC algorithm calculates by breaking down the angle into number of rotation whereas the modified CORDIC calculates by breaking the rotation into nanorotation and makes use of novel set of angles which reduces the number of iterations ,thus accuracy is increased and latency is reduced .In this paper we have carried out MATLab simulation to determining the reduced number of iterations, increased accuracy and reduction in latency between existing CORDIC and modified CORDIC II algorithm. Keywords: CORDIC, trigonometric, logarithm, exponential function.
