基於可變因子CORDIC新演算法的座標轉換

Abstract

In this paper we will describe our new CORDIC algorithms which are applied in coordinate transformation using variable factors. In our simulation for our new algorithms .the number of iterations is 12 maximum with the accuracy of 23 bit length. This is accomplished by suing signed two bits. Instead of one to process at a time, Simulation results show that the accuracy can be up to 99% maximum and 96% minimum. Besides, our new algorithms are multiplication-free and division-free and keep the original concept of the classical CORDIC algorithms
