An efficient CORDIC arithmetic unit for 3-phase voltage grid synchronization

The aim of this paper is to implement the CORDIC algorithm in the most used 3-phase voltage grid synchronization techniques. The CORDIC algorithm is an efficient trigonometric calculus processor, which makes possible to solve complex trigonometric functions by means of a shift-adder structure, thus obtaining a very efficient calculus core which achieves a short computation time when used in FPGA or ASIC platforms.
