使用QUARTUS2写的循环码编码器源代码-Writing of the use of cyclic codes QUARTUS2 encoder source code

计算输入字符串的CRC编码。CRC编码即循环冗余码，它是利用除法及余数的原理来作错误侦测的。-Calculate the CRC coding of the input string. The CRC encoder that cyclic redundancy code, which is the principle of the division and the remainder for error detection.
