Verilog code for Sine Cos and Arctan Xilinx CORDIC IP core Verilog by VLSI Universe - June 5, 2021July 21, 20210 Generation CORDIC IP core functions for the implementation of trigonometric functions such as sine, cos, and arctan in the Xilinx ISE 14.7. This article helps you to understand the steps to be followed to get a code from Xilinx IP core and run it. The IP core model allows us to select the bit widths for the operation 16bit or 32bit and also the number of iterations. The larger the number of coarse iterations for the CORDIC algorithm, the more will the results accuracy. These IP cores are so accurate and synthesizable codes. One can generate the RTL model and the design summary tables for the implemented CORDIC functions. These are more faster and efficient in the form of hardware complexity and
Verilog code for sine cos and arctan using CORDIC Algorithm Verilog by VLSI Universe - June 3, 2021July 21, 20210 Hardware implementation of trigonometric functions such as sine, cosine and tangent functions using Verilog HDL. Here we make use of CORDIC algorithm to implement these functions in Verilog. It is important to to write a synthesizable code in Verilog to implement on hardware such as FPGA's. The computation of the functions helps to analyze sine wave generation and phase and magnitude calculation of several signals. 1. Basics of CORDIC Algorithm 1.1 Need for CORDIC Algorithm There are several approaches such as the Lookup table method and Polynomial series (for example, Taylor series) to implement these sine, cosine and tangent trigonometric functions. They have complications such as cost of the implementation and the hardware complexity of the design. In case Lookup table method it is fast
