Abstract
Multiple cyclic redundancy check (CRC) engines for checking/appending CRCs during data transfers. Two distinctly implemented CRC engines are employed to enable the processing of different sized byte formats at two ends of a communication channel. These two distinctly implemented CRC engines can be employed to enable the processing of different sized byte formats in a host device at one end and an hard disk drive (HDD) at another end. For example, sometimes the size of blocks, frames, and/or sector sizes that are processed and employed within a first communication device at one end of a communication channel can differ from the size of blocks, frames, and/or sector sizes that are processed and employed within a second communication device at another end of the communication channel. Two distinctly implemented CRC engines allow the appropriate processing and translation of any desired different sized blocks, frames, and/or sector sizes of a communication channel.
