Description: crc任意位生成多项式
任意位运算
自适应算法
循环冗余校验码(CRC，Cyclic Redundancy Code)是采用多项式的
编码方式，这种方法把要发送的数据看成是一个多项式的系数
，数据为bn-1bn-2…b1b0 (其中为0或1)，则其对应的多项式为：
bn-1Xn-1+bn-2Xn-2+…+b１X+b０
例如：数据“10010101”可以写为多项式
X７+X４+X２+1。
循环冗余校验CRC
循环冗余校验方法的原理如下：
(1) 设要发送的数据对应的多项式为P(x)。
(2) 发送方和接收方约定一个生成多项式G(x)，设该生成多项式
的最高次幂为r。
(3) 在数据块的末尾添加r个0，则其相对应的多项式为M(x)=XrP(x)
。(左移r位)
(4) 用M(x)除以G(x)，获得商Q(x)和余式R(x)，则 M(x)=Q(x)
×G(x)+R(x)。
(5) 令T(x)=M(x)+R(x)，采用模2运算，T(x)所对应的数据是在原数
据块的末尾加上余式所对应的数据得到的。
(6) 发送T(x)所对应的数据。
(7) 设接收端接收到的数据对应的多项式为T’(x)，将T’(x)除以G(x)
，若余式为0，则认为没有错误，否则认为有错。-crc-generating polynomial arbitrary Operators adaptive algorithm Cyclic Redundancy Check (CRC. Cyclic Redundancy Code) is the polynomial coder, This way the data to be sent as a polynomial coefficient data bn- 1bn-2 ... b1b0 (0 or 1), corresponding to the polynomial : bn- 1Xn-1 bn- 2Xn-2 ... b1X belts such as : data "10010101" polynomial can be written as a X7 X4 X2. Cyclic Redundancy Check Cyclic Redundancy Check method of principle as follows : (1) The data to be sent to the corresponding polynomial p (x). (2) the sender and the receiver agreed on a generator polynomial G (x), set up the generator polynomial of the highest power of r. (3) In the data block Add to the end of r-0, then the polynomial corresponding to M (x) = XrP (x). (R-bits) (4) M (x) divided by G (

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
