摘要
在介绍CORDIC算法原理的基础上,提出了基于CORDIC算法的直角坐标与球面坐标变换电路的工作原理,并结合现场可编程门阵列(FPGA)的特点,给出了变换电路的FPGA实现方法,最后利用Quartus Ⅱ软件进行了直角坐标到球面坐标变换电路的编程实现和时序仿真,并在EP2S90F1020I4上验证了设计的有效性和可靠性。
This paper introduces the principle of CORDIC algorithm,and based on this,brings forward the operation principle of transformation circuit between rectangular coordinate and spherical coordinate based on CORDIC algorithm,combining the characteristics of field programmable gate array（FPGA）,gives the realization method of transformation circuit based on FPGA,lastly performs the programming realization and sequential simulation of transformation circuit from rectangular coordinate into spherical coordinate by means of Quartus Ⅱ software,and validates the validity and reliability of the design for EP2S90F1020I4.
