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。

蓝牙协议This specification describes the Audio/Video Control Transport Protocol (AVCTP), which is used to transport command and response messages for controlling Audio Video features in conformant devices. This protocol enables a device to support more than one control profile at the same time each supported profile shall define its own message formatting and/or usage rules.

Its a text-fading linking ticker type applet that will fade text of any color over any color background. It features rollover color feedback, and will pause when rolled over so the user doesn t have to "chase" links. It uses very little processor power and source is included! Now supports frames!
