Honghuang, I am engaged in science and technology in the Wuzu

Due to the lack of human resources, there is no way to use human resources on earth to accelerate research and development, and the Institute can only use time to slowly overcome these problems.

The days of flooding are also comfortable, and the progress of the project is proceeding slowly, always testing the limits of everyone’s wisdom.

The Redstone Tribe grew stronger and stronger, and its domination continued to expand, and every once in a while several demon or human races joined the institute, but overall, the speed of research was very touching.

Except for the busy research institute, most of the tribal people practiced in seclusion, and the days seemed deserted.

After the screening of time, many people have given up the path of scientific research, which is really amazing.

In fact, the most striking thing about the Redstone Tribe is the progress of cultivation research, with Fang Hao as an example, and Feng has also become a cultivation research institute.

Inspired by Fang Hao’s knowledge of bioengineering, Feng began to study biological genes, combining genes and cultivation, and produced many remarkable results.

In terms of traditional cultivation, every once in a while, brilliant spells are invented, which then increase the cultivation speed of everyone.

Countless tribes could not stand the temptation of power to join the Cultivation Institute, and although Fang Hao’s Academy of Sciences was also popular, it was gradually fading.

For this matter, Fang Hao is not in a hurry, science is a very attractive physical object, with beauty that ordinary people cannot find, naturally this is for people who really understand science.

For outsiders, scientific research is a boring thing, they do not understand people who are obsessed with scientific research.

In the eyes of ordinary people, people who conduct scientific research are scientific madmen and behave very strangely.

After a year of demonstration and research, Fang Hao’s team finally completed the research on the logic gate circuit at the cost of burning tens of thousands of electron tubes.

This study not only clarified the design of logic gates, but also collected a large amount of data, found many shortcomings in current tube technology, and improved several versions of tube design.

Not only that, the tribesmen also found a better electrode material, making the performance of the tube higher, but this material is a cultivation material, which has a spiritual energy existence that Fang Hao does not understand, and cannot be processed on a large scale.

Fang Hao still cares more about natural materials, which is conducive to reducing the cost of mass production in the later stage, and it is also convenient to sell to the Flood Barren Continent, after all, the Flood Barren Continent is too big.

For Reiki, the entire tribe is studying, but so far has not studied clearly, in fact, Reiki is not qi, but a thing that cannot be seen and touched, most likely a dark matter, with the tribe’s current technology is still inaccessible, let alone studied.

Fang Hao didn’t really like to use substances containing spiritual energy to make tubes, and science couldn’t stand things that it couldn’t control.

He planned ahead, focusing on the study of materials existing in nature to make electronic tubes, and located the huge market of the entire flood famine in advance, he wanted to use science to influence the entire flood famine, and eventually use information science to indirectly control the entire world.

Logic gates include three categories, the first is non-gate, the second is with gates, and the third is OR gates.

These gates have been thoroughly studied, detailed data sheets have been compiled, and comprehensive tests have been carried out on performance, frequency, power consumption, heat dissipation, life, etc., to determine the optimal state of use.

Non-gate operation: The input and output results are reversed.

AND operation: The result is 1 only if the inputs are all 1.

OR gate operation: When there is an input of 1, the result is 1.

OR non-operation: negates the result of the OR operation.

AND operation: Negates the result of the AND operation.

With logic gates, I began to design four operations of addition, subtraction, multiplication, and division, and in fact, the computer would only do addition.

If you want to do other operations, you need to convert the other operations to addition.

Inside the computer, all operations are addition, but the addition calculation of the computer is very anti-human, not human thinking, but machine thinking.

First of all, the computer converts the number into binary, all 0 and 1 codes, and the conversion is carried out according to ready-made programs.

If the addition is calculated, the two numbers are added bitwise, such as 13+15, and after conversion it is 1101+1111, according to the rule of 0+0=0, 1+0=0+1=1, 1+1=10, the result is 11100, and then converted to 28 when output.

If it is a calculation subtraction, take the subtraction as a complement, replace 0 with 1 and 1 with 0, add 1 later, and add it again.

Take the eight-digit data calculation as an example, calculate 15-13,

Convert 15=**,13=**,

Take the complement of 13 as **, and add 1 to **,

Add up with **+**=**, the number of digits has exceeded eight digits, discard the highest bit, and take the last eight digits as **, that is, 2 in decimal.

The calculations here feel complicated and not easy to understand.

In fact, the computer is not troublesome to calculate, and even very simple and fast, because there is an adder inside the computer, and an addition can be calculated once in a few clock cycles, plus the computer is all automatic calculations, completed by the adder, and the calculation is very fast.

If the human brain tracks these calculations, it will feel that the computer is too stupid, and the simple subtraction does not know how many times it has been run.

A functional module called ALU in the computer, which has many hardware computing circuits, such as addition, subtraction, multiplication and division, open exponent, exponential, differential, integral, and so on.

These hardware can directly handle the most basic calculations, speed up the calculation of data, is a fool’s calculation, all processes are integrated in the hardware.

Naturally, addition, subtraction, multiplication and division, opening exponents, exponents, differentiation, integrals, etc. operations are also realized by addition, there are many mathematical theories here, and computers are actually the crystallization of mathematical ideas.

The ALU also has a function to decide which operation to perform, the mathematical operator sign on the keyboard is used to determine the choice of ALI, if the calculation is more complicated, you can select the ALU through the software to perform that kind of calculation.

To design a computer, we must first design ALU, that is, design an adder, and the internal adders of the computer include a full adder, a ripple carry adder, and a super-forward adder.

A full adder can only perform one binary addition, with a full adder, you can do the addition of multi-bit binary numbers, as long as the input and output of multiple full adders are connected, just like multi-bit addition.

A ripple carry adder is an adder that connects many full adders in series, and it can perform multi-bit additions.

However, this adder has a defect, that is, the bit operation is too slow, and the calculation of each bit must wait until the end of the operation of the previous bit before the operation can be performed, resulting in if the number of operation bits is very large, the entire adder operation will be very slow, so the ripple carry adder can only do the addition calculation with fewer bits.

If you want to perform an addition calculation with more bits, you must design a super-forward bit adder, which does not need to wait for the end of the previous bit operation, but can directly obtain the value of the current bit through Boolean operations, and the calculation method is to use hardware calculation.

Therefore, the super-forward adder also has defects, because to use hardware for Boolean operations, the more bits the circuit, the more complex the circuit, which will not only slow the operation, but also the cost will become higher.

The Boolean operation with hardware also requires the use of an adder, so the super-forward adder is also implemented by the full adder, but with more full adders, it constitutes a super-forward bit full adder.

In this way, the Boolean module and the super-forward adder contain each other, forming an extremely complex structure.

But no matter how complex it is, as long as the design is successful, it can be used directly in the future, without the need to analyze and design again.

In addition to the adder, there are subtraction, multiplication, division, etc., which is necessary for computers.

To perform complex calculations, computers need to use the principles of numerical calculation methods, or transform various mathematical functions into polynomials with only addition, subtraction, multiplication and division, or use iterative calculations, or approximate calculations, and so on.

This is again a new field of mathematics.
