Chapter 350 Three Judges

Lin Hong had expected this change of Wu Dong. His personality is very suitable for technology, and the other two in the dormitory are a little inappropriate.

Technicians generally tolerate loneliness, have a sense of research, and have an idea to understand the context of any technology.

Wu Dong's technical foundation was too weak before, mainly because he rarely came into contact with this aspect before. His vision mainly came from books. What content in the book is, what knowledge he has. But he has a tossing heart and wants to understand what knowledge. After all, he will do his best and concentrate all his energy.

In less than two months, Wu Dong went from a rookie who had nothing to do with computer hardware to a semi-professional who was fully qualified for computer maintenance. On the one hand, he was willing to study and willing to study, and on the other hand, he often had problems with the second-hand computers he bought, in order to When the computer worked normally, he had to find a way to solve it.

If he buys a brand machine, because the price is expensive and the machine is new, he will not have the courage to tear off the repair seal for at least a few months. He can't even see the internal structure of the machine, and the quality of the brand computer is also good. Maybe there will be no problems in a year and a half.

There is no problem with the computer, which is good news for ordinary users. They just need to use it. But for those who want to learn technology, it is bad news.

It is an excellent way to learn knowledge by finding problems and then solving them.

This teaching method is used more skillfully in American universities. Lin Hong deeply understood this when he was in a Latin school before.

The teachers assign homework after class, not to tell the students which questions and papers they should do, but to choose a topic, and then let the students do a survey around the topic, and then write a paper.

At the beginning, all the students who had just come from China were also a little uncomfortable with this method. After all, they had never come into contact with this area before. Suddenly, they said that they wanted to write a paper. It sounded like a very big project, and they would subconsciously have a sense of fear and at a loss.

However, when they have really experienced it several times, they will find that this kind of homework is very good. In the process of investigating and looking for cases, they will learn a lot of knowledge, and this knowledge is usually difficult to forget because they have a unique experience.

Lin Hong called it "experiential learning" or "practice comes from true knowledge".

This teaching method has been quite mature in foreign countries. Whether it is the teaching concept of teachers or the evaluation system of academic performance, there is a set of mature mechanisms.

In China, this way can only be seen in universities, and unfortunately, the imitation is not very decent. Although it always seems to assign homework in this way, it lacks correct guidance to students. In addition, the evaluation of the final result is not very scientific, and the final result is too important, and the final result is too important. Failure to pay attention to the process leads to this kind of teaching method being formal. In fact, it still does not jump out of the scope of traditional cramming teaching.

When Wu Dong kept running to the library reading room to check computer magazines, Lin Hong did not rest.

He has been soaking in the school library for a while, and the books he read are mainly about bioengineering.

Usually, if he sees a well-known professor in this regard, he will also go to the class of his senior year.

The class in the university is very casual. If you want to come to listen to the class, you don't care about it. Even if you want to, you can't control it, because in most cases, it is a large classroom, one or two hundred people have a class, many classes together, many people don't know each other at all.

Although there are several powerful professors from the Department of Bioengineering of Shuimu University who have returned from abroad, what Lin Hong has done so far is not convenient to disclose to them. If he runs to tell others, I want to write a superbrain system in my brain, which involves knowledge of bioengineering, not It's strange that others treat you as a madman.

At ordinary times, Lin Hong prefers to study alone.

Of course, he will not miss the existing theory. He knows very well that standing on the "giant's shoulder" can save him a lot of time.

Therefore, the super worm has another task to search and rescue the bioengineering technology he is interested in. The world's famous laboratories are basically connected to the Internet. As long as relevant bioengineering technologies appear in their daily use of computers, they will be secretly collected by the super worm and finally stored in The distributed database is available for Lin Hong to consult at any time.

Inspired by the BacMRWb search engine, Lin Hong has also made subtle changes to the super worm. After all, the database he has collected now is getting larger and larger, and it is impossible for him to read all the information. Except for very important information, everything else is generally simply stored, and finally Search from these results when he needs it.

processes a large amount of data, which involves a search ranking problem. Lin Hong also introduced several parameters and rated the weight of this information, which greatly improved the efficiency of the search.

On this day, he said hello to the people in the dormitory, so he returned to the laboratory.

He is going to start a very important experiment today to implement an "additioner" in the brain on the basis of "switching protein".

Addition is the most important operation in a computer. If you want to make a computer, you must first solve the problem of addition.

addition is solved, and subtraction, multiplication and division are naturally solved, which can be changed on the basis of addition to complete the operation.

Addition is the only thing a computer CPU does. After solving this problem, the solution of other problems is just a matter of time. It can be used for mathematical calculations, calculation of complex ballistic parameters, and even launching satellites and controlling spacecraft.

The CPU has many component modules, such as arithmetic logic units, program counters, coprocessors, etc. These modules are the most frequently used in the CPU, and the adder is the core component of these modules, and almost all the key paths are related to them.

If Lin Hong wants to start a superbrain system, the first step is to construct the CPU hardware structure, and the adder is the most critical step in the whole CPU design.

These days, he has been working hard to construct a superbrain adder. For this reason, he has specially studied the relevant knowledge of CPU design, and also intermittently tested switching proteins to find a way to communicate between these proteins.

The adder is the basis of the CPU, and the adder is based on the three simplest logic circuits: with gate, or gate and non-gate.

Gate circuit is a logical operation, which is actually designed according to binary operation rules. The gate circuit is divided into two parts: input and output. The rule with the gate is that as long as one of the inputs is "then the output is", as long as one of them is 0, the result is 0. In computers, 0 and 1 are usually expressed by the potential of the voltage.

"With the door" is like a very strict referee. As long as you do a bad thing (input 0), you must be judged to be a bad person. Only when you sit on a good person twice (1) can you be regarded as a good person.

"Or the door" is a good referee. His judgment standard is relatively loose. As long as you do a good thing, he will identify you as a good person. Only when you do all the bad things will you be regarded as a bad person.

And the "non" door is even simpler. This referee is incompetent and always sings the opposite. You do bad things. He thinks you are a good person, but he does good things, but he thinks you are a bad person.

There are also some relatively derived gate circuits, such as non-gate, or non-gate, heterogeneous gate and three-state gate. These circuits are expanded from the three most basic circuits. They are upgraded versions of those three referees. As long as the three most basic referees are cultivated, other senior referees will not be mentioned. .

The first step for Lin Hong to do is to find a way to make these three kinds of "judictionary", and the basic material he now has is "switching protein".

He has been studying the connection between switching proteins these days, and finally found that fluctuations can also be used to communicate between them. This kind of energy fluctuation is a bit similar to the propagation of electrical energy. The speed is also very fast, and there is no delay at all.

After learning from the last experience, Lin Hong bought physical objects and drinking water from the store for about three days, and then shrank into the laboratory.

The first step he needs to do now is to use two switching proteins to construct a referee. When the state of the No. 1 switching protein is "open", the No. 2 switching protein must be "closed", and vice versa.

The birth of switching protein requires the stimulation of energy field vibration. For this reason, Lin Hong had to design a "switching protein generator" whose function is to provide special frequency of energy vibration, so that switching protein can be generated inside the brain. Lin Hong added an adjustable frequency module to it, so that different kinds of switching proteins can be produced.

With the last experience, this time he only took about two hours to put this "switch protein generator" followed by a long experiment and testing process.

After five hours, Lin Hong finally showed a relaxed look on his face. He made the first progress, found the stimulation frequency of the "switching protein" that constructed the "sang the opposite tone referee", and successfully connected the two switching proteins together, forming a "non-door".

Two hours later, the protein material of the "strict referee" was also successfully found by Lin Hong.

An hour later, the "good man referee" was also successfully constructed.

So far, the three basic logic gate circuits have been successfully realized by Lin Hong.

Lin Hong did not stop, but realized all the non-door, or non-door, different or three-door and three-door.
