CORDIC (Coordinate Rotation Digital Computer) algorithm that coordinate rotation digital computation method is JDVolder1 first proposed in 1959, mainly for trigonometric, hyperbolic, exponential, to calculate the number. The algorithm basic addition and shift operations instead of multiplication, such that rotation of the orientation vector calculations and no longer need to trigonometric functions, multiplication, square root, inverse trigonometric, exponential and other functions.
