Abstract :
In this paper we implemented a single-precision floating-point CORDIC algorithm in rotation mode. The architecture of floating point CORDIC algorithm is in a floating-point representation for the angle. The angle is represented as a combination of exponent, microrotation bits and two bits to indicates rotation over 0 to π radians. Representing floating-point angle in this form maintains the accuracy that is presented in the input data which makes it to suitable for implementing a floating-point given operations.
