crc任意位生成多項式 任意位運算 自適應算法 循環(huán)冗余校驗碼(CRC，Cyclic Redundancy Code)是采用多項式的 編碼方式，這種方法把要發(fā)送的數(shù)據(jù)看成是一個多項式的系數(shù) ，數(shù)據(jù)為bn-1bn-2…b1b0 (其中為0或1)，則其對應的多項式為： bn-1Xn-1+bn-2Xn-2+…+b１X+b０ 例如：數(shù)據(jù)“10010101”可以寫為多項式 X７+X４+X２+1。 循環(huán)冗余校驗CRC 循環(huán)冗余校驗方法的原理如下： (1) 設(shè)要發(fā)送的數(shù)據(jù)對應的多項式為P(x)。 (2) 發(fā)送方和接收方約定一個生成多項式G(x)，設(shè)該生成多項式 的最高次冪為r。 (3) 在數(shù)據(jù)塊的末尾添加r個0，則其相對應的多項式為M(x)=XrP(x) 。(左移r位) (4) 用M(x)除以G(x)，獲得商Q(x)和余式R(x)，則 M(x)=Q(x) ×G(x)+R(x)。 (5) 令T(x)=M(x)+R(x)，采用模2運算，T(x)所對應的數(shù)據(jù)是在原數(shù) 據(jù)塊的末尾加上余式所對應的數(shù)據(jù)得到的。 (6) 發(fā)送T(x)所對應的數(shù)據(jù)。 (7) 設(shè)接收端接收到的數(shù)據(jù)對應的多項式為T’(x)，將T’(x)除以G(x) ，若余式為0，則認為沒有錯誤，否則認為有錯

This sample displays a basic integer calculator powered by the 8051 microcontroller. Although Keil C51 has a full floating point math library the evaluation version is restricted to 2k of object code, so we have constrained this sample to integer maths in order to fit within this limit. The program for this design was written in C using the Keil uVision 2 IDE for which Proteus VSM provides a Debug Monitor driver. Instructions for configuring Proteus to run in conjunction with the Keil environment can be found by editing the 8051 microcontroller on the schematic (point at it and press CTRL-E) and then clicking on the help button on the Edit Component dialogue form.
