Description: 可以将以bit为单位进行处理的算法扩展到8位，即以Byte为单位进行处理。由于有8个bit，所以有2^8种选择。这样明显会使运行时
间大为减少，速度明显更快，但是也有它的缺点，即，占用资源太大，所以综合考虑速度和 资源两点，采用半字节查表法。即以半
Byte为单位进行处理。由于有4个bit，所以有2^4种选择。-bit can be processed for the extension of the algorithm 8, to Byte unit for treatment. With 8 bit, it is 2 ^ 8 options. This will significantly reduce travel time significantly, significantly faster speed, but it also has its drawbacks, namely, taking up too much resources. Therefore, considering the speed and resources 2:00, semi-byte look-up table method. Byte is a semi-processed as a unit. As a four bit, it is 2 ^ 4 choice.

Description: 生成多项式的最高位必须是1。例如：CRC-CCITT标准的16位生成多项式：g（x）= x16+x12+x1+1；阶数r = 16
即：0x11021.最高位通常为1。-Generating polynomial must be the highest one. For example: CRC-CCITT standard 16-bit generation polynomial: g (x) = x16+ X12+ X1+ 1 order of r = 16 that is: 0x11021. Highest one usually.

Description:
循环冗余码校验英文名称为Cyclical Redundancy Check，简称CRC。它是利用除法及余数的原理来作错误侦测（Error Detecting）的。实际应用时，发送装置计算出CRC值并随数据一同发送给接收装置，接收装置对收到的数据重新计算CRC并与收到的CRC相比较，若两个CRC值不同，则说明数据通讯出现错误。
根据应用环境与习惯的不同，CRC又可分为以下几种标准：
①CRC-12码；
②CRC-16码；
③CRC-CCITT码；
④CRC-32码。
CRC-12码通常用来传送6-bit字符串。CRC-16及CRC-CCITT码则用是来传送8-bit字符，其中CRC-16为美国采用，而CRC-CCITT为欧洲国家所采用。CRC-32码大都被采用在一种称为Point-to-Point的同步传输中。
下面以最常用的CRC-16为例来说明其生成过程。-err
