CORDIC Reference Design

Please contact your local Altera sales representative for a copy of this reference design. The use of this design is governed by, and subject to, the terms and conditions of the Altera Hardware Reference Design License Agreement.
Overview
The coordinate rotation digital computer (CORDIC) reference design implements the CORDIC algorithm, which converts Cartesian to polar coordinates and vice versa. CORDIC is an iterative process, using a series of shifts and adds. Hence it is a hardware-efficient solution compared to using multiplication, division, and square roots.
The reference design comprises a MATLAB bit-accurate model of the CORDIC algorithm implemented in hardware and a graphical user interface (GUI) test environment. The test environment allows you to configure the CORDIC reference design and test conditions and compare the results with the theoretical results.
Separately, Altera® provides the encrypted Verilog hardware description language (HDL) source code, precompiled simulation files for the ModelSim® simulator, and a testbench for the hardware implementation of CORDIC.
