| Abstract: | Fast and accurate computation of the trigonometric function in a modern engineering has been used widely. With the recent research achievement, a new digital hardware architecture based on the CORDIC algorithm is proposed. We finished it in FPGA. Proved in experiments that this architecture is easier to implement and adjust the accuracy of the results, it has great practical value in some applications. |
