The only component missing from the normal and reversed code fragments in the previous section is the lookup table. The lookup table can be computed at run time using the cm_tab function of the model package given earlier, or can be pre-computed and inserted into the C program. In either ...
Wesley Peterson教授,是纠错/检错编码理论的奠基人之一,著有《Error-Correcting Codes》。CRC校验码的发明来自Peterson教授1961年发表的论文《Cyclic Codes for Error Detection》。很遗憾,博主二选一的猜想,刚好猜反CRC校验码的发明者刚好是研究清楚了循环码的数学原理,顺手,不用怀疑,就是顺手提出了一个高效的编码电...
The SIMPLE algorithm above is a good starting point because it corresponds directly to the theory presented so far, and because it is so SIMPLE. However, because it operates at the bit level, it is rather awkward to code (even in C), and inefficient to execute (it has to loop once for...
这个串又叫做''codeword''. CRCs 经常被叫做“[[校验和]]”, 但是这样的说法严格来说并不是准确的,因为技术上来说,校验“和”是通过加法来计算的,而不是CRC这里的除法。 “[[错误纠正编码]]”常常和CRCs紧密相关,其语序纠正在传输过程中所产生的错误。这些编码方式常常和数学原理紧密相关。 ==实现== ==...

__循环冗余校验(CRC)计算单元是根据固定的生成多项式得到任一32位全字的CRC计算结果。__在其他的应用中, CRC技术主要应用于核实数据传输或者数据存储的正确性和完整性。标准EN/IEC 60335-1即提供了一种核实闪存存储器完整性的方法。 CRC计算单元可以在程序运行时计算出软件的标识,之后与在连接时生成的参考标识比较...
CRC Math in C I'm going to complete my 3-part discussion of checksums by showing you how to implement a CRC in C. I'll start with a naive implementation and gradually improve the efficiency of the code as I go along. However, I'm going to keep the discussion at the level of the...
If the remainder is zero, the data is considered error-free. If the remainder is non-zero, it means that errors were detected in the data. What are the advantages of using CRC? CRC has several advantages when it comes to error detection in data transmission. Firstly, it is simple and ...
The checksum error is output as a binary column vector of lengthC. An element value of 0 indicates an error-free received subframe, and an element value of 1 indicates an error occurred in the received subframe. For the scenario shown here, a 16-bit codeword is received with an error ...
