Agree! I like the idea of the comic stylistic choice for the presentation, but maybe toning it down a little bit would be better.

what polynomial would correspond to the shift register used here? (also - fantastic video - outstanding work all 'round)

@bssolutions8351 2 жыл бұрын

I am pretty sure it is, x^5 + x^4 + x^2 + 1 (CRC-5-ITU)

but how do you know how many xor gates to use and where to put them?

@SYEDAfsahul 7 жыл бұрын

Where was generator polynomial used in the process?

@wisconline 7 жыл бұрын

The generator polynomial used to create the feedback registers is x^5+x^4+x^2+1. Note though that I do not believe this meets the criteria for a true CRC. I used this very simple polynomial just to illustrate how the feedback registers work when calculating a CRC code. A true CRC would have 16 or 32 registers.

"there's no delay" -> "let's run this code through the loop again" - Well.. isn't that a delay?

@Leonelf0 6 жыл бұрын

Harry Svensson the data is fed through the registers (generating the CRC) as it's sent out to the receiver, then the crc is sent out aswell. the receiver generates a CRC as it's receiving the data and compares it to the received crc. so the only"delay" is the time it takes to receive/send the CRC. calculation is done when sending/receiving

siclic? it's pronounced cyclic as in i cycle to work...

@wisconline 6 жыл бұрын

Your suggested pronunciation may be more popular but it is acceptable either way [sahy-klik, sik-lik] as found here: unabridged.merriam-webster.com/unabridged/cyclic or here: www.thefreedictionary.com/cyclic The popular pronunciation of both cyclic and cyclical varies around the world. Sometimes it may sound like cycle or sometimes like bicycle. - Thanks!
