CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
detecting errors in a so-called non-volatile memory (here a Flash memory). The CRC
calculation unit helps compute a signature of the software during runtime, to be compared
with a reference signature generated at link-time and stored at a given memory location.
