A naive CRC implementation in C Code Cleanup Before we start making this more efficient, the first thing to do is to clean this naive routine up a bit. In particular, let's start making some assumptions about the applications in which it will most likely be used. First, let's assume ...
So, whereas the implementation of a checksum algorithm based on addition is straightforward, the implementation of a binary division algorithm with an m+c-bit numerator and a c+1-bit denominator is nowhere close. [1] For one thing, there aren't generally any m+c or c+1-bit registers in...
Portable implementation in C Explanation Shown below is a piece of C code that SEGGER actually uses in production code. It first computes a CRC andLSBfor any polynomial of up to 32 bits, and for any amount of data. The starting value can be specified, and the routine can be used to co...

CRC校验的概念及具体实现 概念 CRC(Cyclic redundancy check),循环冗余校验 CRC校验是⽤于检测⼀帧数据发送是否正确，只有确认对错的作⽤，并没有纠错的能⼒。还有⼀点就是CRC校验通过了，并不代表这个数据肯定就是正确的，只能说尽可能减少出错的概率，当然 CRC错了那么这个数据肯定是不正确的。⽽这个概率...
half not. It's really terribly confusing. In particular, it would seem to me that the casual reader who runs into a reflected, table-driven implementation with the bytes "fed in the wrong end" would have Buckley's chance of ever connecting the code to the concept of binary mod 2 ...
This is an implementation of binary long division, in which the message sequence is the divisor (numerator) and the polynomial is the dividend (denominator). The CRC checksum is the remainder of the division operation. Direct CRC Algorithm This block diagram shows the direct CRC algorithm. Where...

in the shift register are XORed with the coefficients of the generator polynomial. When the augmented message sequence is completely sent through the LFSR, the register contains the checksum [d(1) d(2) . . . d(r)]. This is an implementation of binary long division, in which the message...
