Design and Implementation of Floating Point Sine and Cosine Functions Using Xilinx ISE for Analog Circuits
Manoj Duhan, Ishu Ishu · SSRN Electronic Journal · 2018
The paper performs the design and implementation of sine and cosine functions in floating point format. To implement these functions, an iterative shift-add algorithm called Co-Ordinate Rotation Digital Computer (CORDIC) was used. Also, single precision floating point format was used among various IEEE-754 floating point formats which consisted of 32 bits. Software implementation of sine and cosine functions was done using VHDL and module for CORDIC using equations given by Volder (1959) was designed and simulated for wave form.
