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

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
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.
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

I. Problem description:
Calculate (a ^ power) % m, where power is a non-negative big integer, A, M is an integer greater than 1.
Ii. Problem Analysis:
Obviously, power is a big integer, so the overflow of Power computing must be considered. How can
