Abstract
Circuits and methods provide the concurrent calculation of CRC bits for messages from different channels, where one part of a message is received at a time. Context buffers store certain state variables of the CRC calculation for each channel. The context buffers output data in a synchronized manner with the input data so that the proper calculations are done and the proper data is available at the appropriate times.
