JavaScript used to create the bit-wise CRC equations
This is some HTML/ECMAScript code to display tables as shown in computation of CRC (see the reference there about how it is working). It is not very pretty code but the output might be useful. For example, 8 bit input data with polynomial coefficients 0x80 and degree 8 shows that this is simply the computation of 8-bit parity (TRC-1/VRC-1). Or 8 bit input data with polynomial coefficients 0x01 and degree 8 is the same as LRC-8/HRC-8 (simple byte-wise exclusive-or). Save the code in a file like crc.html and load it in a browser. Feel free to use and/or improve/move it…

 * Code noted, thanks again. I also find it useful to plot r against e, putting an X wherever ei contributes to the value of rj .  The same information appears in a visual pattern.  – Regregex (talk) 23:43, 31 July 2009 (UTC)
