crc任意位生成多項式 任意位運算 自適應算法 循環冗余校驗碼(CRC,Cyclic Redundancy Code)是采用多項式的 編碼方式,這種方法把要發送的數據看成是一個多項式的系數 ,數據為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:數據“10010101”可以寫為多項式 X7+X4+X2+1。 循環冗余校驗CRC 循環冗余校驗方法的原理如下: (1) 設要發送的數據對應的多項式為P(x)。 (2) 發送方和接收方約定一個生成多項式G(x),設該生成多項式 的最高次冪為r。 (3) 在數據塊的末尾添加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)所對應的數據是在原數 據塊的末尾加上余式所對應的數據得到的。 (6) 發送T(x)所對應的數據。 (7) 設接收端接收到的數據對應的多項式為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。

Metalog is a modern replacement for syslogd and klogd. The logged messages can be dispatched according to their facility, urgency, program name and/or Perl-compatible regular expressions. Log files can be automatically rotated when they exceed a certain size or age. External shell scripts (e.g., mail) can be launched when specific patterns are found. Metalog is easier to configure than syslogd and syslog-ng, accepts unlimited number of rules and has (switchable) memory bufferization for maximal performance.

This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr
