摘要：

In this brief, we present the CORDIC II algorithm. Like previous CORDIC algorithms, the CORDIC II calculates rotations by breaking down the rotation angle into a series of microrotations. However, the CORDIC II algorithm uses a novel angle set, different from the angles used in previous CORDIC algorithms. The new angle set provides a faster convergence that reduces the number of adders with respect to previous approaches.
