Abstract

With the rapid development of VLSI technology,CORDIC algorithm is widely used.A method of jumping over 0 in the input phase values is adopted to reduce the iterations effectively in this paper.The modified CORDIC algorithm was simulated with ISE simulation technology for several times.The results show that the operational speed of the modified CORDIC algorithm is obviously improved on the premise of ensuring the operational accuracy of the algorithm.The CORDIC algorithm was implemented with FPGA.
