摘要：

For traditional hyperbolic and trigonometric functions calculation algorithms, multiplier and a lookup table are needed to achieve calculation of multiple transcendental functions, which will lead to hardware circuit complexity and lower operation speed. Aim at overcoming the disadvantages of traditional algorithm, a CORDIC algorithm is proposed and implemented by FPGA program. Two types of realization circuits for CORDIC algorithm are implemented into the FPGA and their performances are compared. One is the flatten pipeline and the other is the folded one, while the first performs higher throughput and the last saves more chip area.
