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: 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: The 16-bit CRC checksum. The algorithm used is CRC-CCITT. The CRC calcula-
tion includes all bytes of the frame. The data bytes have to be calculated as a
word. At first you have to shift in the high byte of the data word. This is the opposite
way you transmit the data word. The 16-bit generator polynomial ‘x16
+x12
+x5
+1’ is
used for the calculation.
