Abstract
There are several ways to define trigonometric signals; CORDIC is the more efficient algorithm to perform trigonometric operations for generating sine and cosine waveforms. By using rotation and vectoring modes in the coordinate system implementation in hardware becomes easy, and also different scaling factors and its compensated techniques can also be calculated further. The proposed system can generate sine and cosine signals in signal processing applications. Also, we can perform hyperbolic and exponential calculations. It can be further enhanced by extending for extended hyperbolic and linear coordinates for the trigonometric functions and inverse trigonometric functions. The proposed project is implemented in Xilinx ISE 13.2, and the output waveforms are simulated in Questasim 10.0b. The design implementation of CORIDC algorithm thus reduces the hardware implementation by using shift registers and adders, thereby increases its speed.
