Cyclic Redundancy Check (CRC) is an error-checking code that is widely used in data

communication systems and other serial data transmission systems. CRC is based on

polynomial manipulations using modulo arithmetic. Some of the common Cyclic Redundancy

Check standards are CRC-8, CRC-12, CRC-16, CRC-32, and CRC-CCIT. This application note

discusses the implementation of an IEEE 802.3 CRC in a Virtex™ device. The reference

design provided with this application note provides Verilog point solutions for CRC-8, CRC-12,

CRC-16, and CRC-32. The Perl scr ipt (crcgen.pl) used to generate this code is also

included. The scr ipt generates Verilog source for CRC circuitry of any width (8, 12, 16, 32), any

polynomial, and any data input width.-Cyclic Redundancy Check (CRC) is an error-checking code that is widely used in data communication systems and other serial data transmission systems.
