发明名称 Method and apparatus for determining a cyclic redundancy check (CRC) for a data message
摘要 A method of creatine a CRC (Cyclic Redundancy Check) code for a data message in a data communications system includes sequentially placing portions of the data message on a bus of width W bits consisting of an integral number N of segments of width S. An initial portion of the message fills n complete segments, where n<N. The method further includes processing the initial portion of the message placed on the bus to compute a CRC while compensating for any data on the bus preceding the initial portion, and subsequently processing one or more following portions of the message placed on the bus to update the CRC. A final portion of the message is processed to update the CRC by separately processing complete segments that do not fill the bus and any bytes that do not completely fill the last segment.
