An Arithmetic Checksum for Serial Transmissions
John George Fletcher · IEEE Transactions on Communications · 1982
An error-detection method for serial transmissions is presented that uses an integer arithmetic checksum. The checksum is compared with cyclic-redundancy-check methods with regard to error-detecting ability and efficiency of implementation in software (or firmware). The method is a bit weaker at detection but is more efficient, thus representing a different and potentially useful choice in rhobust-benefit spectrum.
