英文摘要	Coordinate Rotation Digital Computer (CORDIC) algorithm is well known and widely used in many computer systems due to its simplicity and the variety of functions it provides. Although CORDIC is known to be able to work in several modes and coordinate to provide elementary functions including trigonometric and transcendental functions, most proposed CORDIC enhancement and application were only limited to a single or only a few modes, and that does not help to build a CORDIC coprocessor that works in all modes. This paper presents an enhanced version of double rotation method which is a scaling-free and redundant arithmetic based CORDIC variation. The proposed algorithm has been implemented and it is shown that the new architectures have great advantage on both FPGA and ASIC platforms and are extremely attractive for high precision and high performance computing. © 2014 IEEE.
