摘要：

In order to improve the precision of coordinate rotation digital computer (CORDIC) algorithm and reduce the hardware resource consumption, research on the convergence and the selection of rotation sequence was conducted. Optimization measures were proposed according to angular coverage, hardware resources and computing precision of CORDIC algorithm for circular system. Sine and cosine functions and reverse tangent functions based on pipeline structure were implemented on FPGA, and computing precision and hardware resource consumption were compared with Xilinx IP core. Comparison shows that the optimized algorithm which improves the computing precision can also reduce the hardware resource consumption effectively. © 2015, Beijing Institute of Technology.
