FPGA Implementation of a CORDIC Algorithm

CORDIC(Coordinate Rotation Digital Computer)algorithm is the main method to realize the fast and accurate trigonometric function,and is widely used in modern engineering.Based on the study of simple state machine realization and fast pipe-line realization of CORDIC algorithm,propose a new floating-point algorithm's optimized realization,and implement it on ALTERA's FPGA.The result indicates that the optimized realization calculates faster than the simple state machine realization of CORDIC algorithm,while use less resources.This realization realizes the balance between the resource consumption and speed.
