The generator constant in the code sample has a "1" that is
not in the
CRC polynomials are usually written without the leading term.
constant in the code has the term is an implementation detail
example, if the CRC width is the same as the word width (e.g.
a CRC-32), it's
easier and faster not to write it that way.
