Modulo 2 is a binary algorithm, the core ofCRC calibration technology, so before we analyze the CRC algorithm, we must grasp the rules of modulo 2 operation. In the same way as arithmetic, modulo 2 also includes modulo 2 plus, modulo 2 minus, modulo
1. What is modulo 2 operation?
First of all, what is modulo 2? Modulo: The remainder, then, modulo 2, is divided by 2 to obtain the remainder.
Again, what is arithmetic? is subtraction.
That is, the modulo 2 operation, can be opened up in this way:
Key words: CRC algorithm principle; CRC verification; modulo 2 (mod 2); mod 2The CRC verification algorithm adopts a binary algorithm called "modulo 2 operation. The modulo 2 operation is the core part of the CRC operation. Therefore, before

Complement and modulo, complementI. Reasons for this article
I did some research on reverse code, complement code, and floating point number yesterday, but there are still some omissions. I discussed it with the fans in the dormitory at night.
Modulo and remainder, modulo RemainderFor integer a and B, the modulo or remainder operations are all performed: 1. evaluate the integer quotient: c = a/B; 2. modulus or remainder: r = a-c * B. the modulo operation and the remainder operation are
Summary: We know that in different languages, the results of negative number modulo operations may be different. For example, (-11) % 5 calculates 4 in Python and-1 in C (c99. Truncate division floor division in most programming languages, if the
Typically, modulo operations (MoD) and remainder (REM) operations are confused, because in most programming languages, the '% ' notation is used to represent modulo or remainder operations. Here we want to remind you to pay attention to the specific
