1. Overview
This section explains the overview of the CRC.
This module calculates CRC values.
CRC (Cyclic Redundancy Check) is a kind of error detection methods. CRC codes are remainders left when
input data strings, regarded as high-degree polynomials, are divided by predefined generator polynomials.
Normally, a CRC code is attached at the end of a data string, and received data is regarded as correct if the
data leaves no remainder when divided by the same generator polynomial.
