Introduction

›

The Flexible CRC Engine (FCE) provides a parallel implementation of
Cyclic Redundancy Code (CRC) algorithms.

›

FCE module supported algorithms:

–

IEEE 802.3 Ethernet CRC32 polynomial

–

CCITT CRC16 polynomial

–

SAE J1850 CRC8 polynomial

›

CRC algorithms are used to calculate message signatures that can be
used to check message integrity during transport over communication.
