3-3. Algorithm
To summarize the principle described in 3-1, algorithms CODIC method is as follows.
Also, I is shown in Figure 4 as a flow chart of these algorithms.

Those that are uploading is being uploaded the solution file of program files and Microsoft Visual Studio for C. It was created and verified under the environment of Microsoft Visual Studio 2010 Version 10.0 40219 SP1Rel as a development environment for C-based.
Upload C program that will input the theta, is a program that outputs a sin and cos. Each output of sin and cos, a result of CORDIC circuit, true value in the input theta, being displayed in the result and the true value difference between the binary and decimal.
