Description: CRC校验原理
1、循环校验码（CRC码）：是数据通信领域中最常用的一种差错校验码，其特征是信息字段和校验字段的长度可以任意选定。
2、生成CRC码的基本原理：任意一个由二进制位串组成的代码都可以和一个系数仅为‘0’和‘1’取值的多项式一一对应。例如：-Principle 1 CRC checksum, cyclic checksum (CRC code): is the data communications of the most commonly used error checking code, which is characterized by the information field and verify the length of the field can be arbitrarily selected. 2, CRC code generated the basic principle: an arbitrary bit string formed by the binary code can be a factor of only ' 0 ' and ' 1' values correspond to a polynomial. For example: ~ ~ ~ Platform: |

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.
