`comm.CRCDetector`	Detect errors in input data using CRC
`comm.HDLCRCGenerator`	Generate CRC code bits and append to input data
`comm.HDLCRCDetector`	Detect errors in input data using CRC

General CRC Generator	Generate CRC code bits according to generator polynomial and append to input data frames
General CRC Syndrome Detector	Detect errors in received codeword frames according to generator polynomial
General CRC Generator HDL Optimized	Generate CRC code bits and append them to input data
General CRC Syndrome Detector HDL Optimized	Detect errors in input data using CRC

Cyclic redundancy check (CRC) coding is an error-control coding technique for detecting errors that occur when a message is transmitted.
