Study of CORDIC algorithm based on FPGA

The CORDIC algorithm is the most important algorithm to achieve sine-cosine signal. This paper discussed the architecture of FPGA implementation, optimization measures were proposed according to hardwarere sources, angular coverage and computing precision of the algorithm. There are 3 main problems for hardware implementation of CORDIC algorithm, based on the basic principle of the algorithm. Combined with conversion quadrant method, pipeline technology and quantitative data format, CORDIC algorithm is implemented in FPGA. The amplitude of the sine-cosine signal can be calculated in a clock cycle. The simulation results show that the accuracy and speed of the optimized algorithm is high, and it reduce the hardwarere source consumption effectively.
