Abstract
A method of determining an error detection code (EDC) on incoming data which includes a reserved bit field, comprising applying the incoming data to inputs of both an input data CRC (IDC) calculator and to an input data and reserved field CRC (IDRC) calculator, calculating the EDC on successive input data words and recursively updating the EDC in both the IDC and IDRC calculators, selecting a payload of the input data as a system output signal for all payload words, and subsequently selecting a output EDC word from the IDRC calculator in a time immediately following a final payload word which contains the reserved field.
