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
Modulo 2 is a binary algorithm, the core of CRC 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,
In many cases, modulo operations are used. Here we describe some pattern operations and prove them. The practical application of these theories will be recorded and explained in the future.
1. The modulo operation is a remainder operation (recorded
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.
[to] the difference between the modulo operation and the remainder operationIn general, modulo operations (mods) and Redundancy (REM) operations are confused because in most programming languages, the '% ' notation is used to denote modulo or
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
Note: This is just my personal understanding. It may be incorrect.
For integers A and N, the modulo n operation is to calculate the remainder of a divided by N.
If a = 10, n = 3, the quotient of a divided by N is 3, and the remainder is 1.
C
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
