摘要
针对软件实现坐标变换速度慢而传统算法的硬件实现又非常复杂的缺点,根据CORDIC算法只需简单的移位加减运算就能实现许多复杂运算的优点,提出了运用CORDIC算法的不同模式进行三维坐标变换,并在FPGA上实现。仿真结果表明:利用该算法实现三维坐标变换在节省硬件资源的同时能兼顾工作速度和精度的需要,具有一定的工程实际意义和应用前景。
Aiming at the shortcomings of slow speed of software coordinate transformation and the complexity of hardware of traditional algorithm, different modes of CADRDIC （Coordinate Rotational Digital Computer） algorithm was used to realize coordinate transformation according to the advantage of CORDIC algorithm that only simple addition and subtraction needed. And the CORDIC algorithm was realized in FPGA. The simulation results showed that this algorithm could meet the demands of high-speed and precision, and save hardware resources.
