A simple terminal program to calculate the crc code of particular input and generation polynomials.

In the terminal, follow the instructions on the menu to set the data to be encoded, the generation polynomial.

To set the generator polynomial recommended in the homework, type in the following command: 6 or 7 and press enter.

To set costomized generator polynomial, type in the following command: 2 and press enter.

For polynomial x^31 + x^3 + 1, input "31 3 0 -1", where -1 is the end of input.

For polynomial x^31 + x^3 + x^2 + x + 1, input "31 3 2 1 0 -1", where -1 is the end of input.

Similarly, press 1 to set the polynomial to be encoded.

Press 3 to see what is in the buffer.

Press 4 to encode the data.

Press 5 to quit the program.

1. Press 6 to set the generator polynomial as x^3 + x^2 + 1.

   

2. Press 1 to set the data to be encoded as x^4 + x^3 + x^2 + x + 1.

   

3. Press 4 to encode the data.

   

   It displays the remainder and the encoded data.

Don't press keys except the numbers on the keyboard.
