Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...

Parity checking and checksums are actually the simplest forms of a cyclic redundancy check (CRC). In mathematical terms, a CRC is the result of a polynomial modulus operation, modulo 2 on the message.

This application note describes how to use the enhanced error detection cyclic redundancy check (CRC) feature in the Arria® II, Stratix® III, Stratix IV, Arria V ...
