Description: 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 script (crcgen.pl) used to generate this code is also
included. The script 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.

Description: 本人根据XMODEM协议的16位CRC校验方式CRC--CCITT(X^16 + X^12 + X^5 + 1)，根据其理论思路一步一步编写的源代码，按照程序思路，会比较容易理解CRC16较验方式的来龙去脉。
-I according to the XMODEM protocol 16 of the CRC method CRC- CCITT (X ^ 16+ X ^ 12+ X ^ 5+ 1), according to their theoretical ideas step by step to write the source code, in accordance with program ideas will be easier to understand the CRC16 more experience in the way of the context. Platform: |
