Abstract:
A CRC redundancy calculation circuit and a design structure including the circuit embodied in a machine readable medium are presented. The CRC redundancy calculation circuit is pipelined to run at high frequencies and configured to operate on an arbitrary multiple of the base granularity of the data packet. Additionally, the CRC redundancy calculation circuit provides the same multiple of outputs that provide intermediary output remainder values. Thus, for example, a circuit which processes 24 bytes of packet data per cycle and which the packets have a 4 byte granularity, the CRC redundancy calculation circuit provides 6 output remainder values, one for each 4 byte slice of data.
