modulo 2 addition

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,

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.

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

About a binary number of 1111000 divided by 1101, modulo 2 Division quotient is 1011, the remainder is 111. This result is different from decimal division. So make a note of it. The specific steps are as follows: #第一步 1111000 1101

Proof and use of Barrett reduction algorithm. The author has just finished the course design work, free to write an article. Exponential operations in large numbers require a number to be modeled, because the maximum possible binary is 2048 bits

Idea: In the past, when I was playing a game, I encountered a lot of situations where I had to calculate the number of combinations. I tried to write recursion instead of brute force or timeout, or because I had to take the modulo, then we also need
