Open publisher page 0 citations

Abstract

An improved cordic(coordinate rotation digital compute) algorithm used to implement the NCO is introduced.The algorithm can predefine the direction of rotation of all iterrations,and reduce hardware resource consumption compared to traditional cordic algorithm.It is implemented on FPGA with the cycloneII-EP2C5AF256A7 chip of Altra company,and the design can fit the requirements.
