Chapter 350 Three Kinds of Judges

For this change in Wu Dong, Lin Hong had long expected it. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Info Templar's latest chapter, his personality is very good for technology, and the other two in the dormitory are a little less suitable.

Technicians are generally more tolerant of loneliness, have a sense of study, and have a desire to understand the ins and outs of any technology.

Wu Dong's technical foundation was too weak before, mainly because he had little contact with this aspect before, and his vision mainly came from books, and what was in the book, what knowledge he had. But he has a tossing heart, he wants to understand something, after all, he will go all out and concentrate all his energy.

In less than two months, Wu Dong has gone from a rookie who has nothing to do with computer hardware to a semi-professional who is fully qualified for computer maintenance, on the one hand, because he is willing to study and study, and on the other hand, because the second-hand computer he bought often has problems, and in order to make the computer run normally, he has to find a way to solve it.

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

If there is no problem with the computer, it is good news for the average user, who can just use it. But it's bad news for people who want to learn technology.

Finding problems and solving them is an excellent way to learn knowledge.

This kind of teaching method is more skillfully used in American colleges and universities, and Lin Hong deeply experienced this when he was a student in Latin School before.

Teachers assign homework after class, and instead of telling students which questions and which papers to do, teachers choose a topic, and then ask students to do research around this topic and then write an essay.

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 been exposed to this part before, and suddenly they said that they were going to write a thesis, which sounded like a very big project, and they would subconsciously have a sense of fear in their hearts and be at a loss. Templar

However, when they actually go through it a few times, they will find that this kind of homework is very good, and they will learn a lot in the process of investigating and finding answers, and this knowledge is often hard to forget because they have a unique experience.

Lin Hong calls it "experiential learning", or "practice makes true knowledge".

This teaching method has been quite mature in foreign countries, and there is a set of mature mechanisms for both the teaching philosophy of teachers and the evaluation system for academic performance.

In China, this method can only be seen in universities, and unfortunately, the imitation is not very decent, although it seems to be in this way to assign homework, but the lack of correct guidance for students, in addition to the final result evaluation is not very scientific, too much attention to the final result, not pay attention to the process, resulting in this teaching method is a mere formality, in fact, it still does not jump out of the traditional cramming teaching category.

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

He spent a lot of time in the school library, reading books mainly about bioengineering.

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

The classes in the university are very casual, and if you want to come and listen to the lectures and audit, you don't have to manage them, and even if you want to, you can't manage them, because in most cases, they are in large classrooms, one or two hundred people in a class, and many classes are together, and many people don't know each other at all.

Although there are several powerful professors in the Department of Bioengineering of Mizuki University in this area, what Lin Hong is doing at the moment is inconvenient to reveal to them, if he runs over and tells others, I want to write a superbrain system in the brain, which involves the knowledge of bioengineering, and it is strange not to be regarded as a madman by others. 《》

Usually, Lin Hong prefers to study on his own.

Of course, he will not miss the existing theories, and he knows very well that standing on the "shoulders of giants" can save him a lot of time.

As a result, the super worm has another task, to search and rescue the bioengineering technology he is interested in, the world's major famous laboratories have basically been networked, as long as their daily use of the computer in the process, there are relevant bioengineering technologies, will be secretly collected by the super worm, and finally stored in a distributed database, for Lin Hong to consult at any time.

Inspired by the backrub search engine, Lin Hong also made subtle changes to the super worm, after all, the database he collected now is getting bigger and bigger, and it is impossible for him to read all the information, except for very important information, the others are generally simply stored, and finally when he needs to, he can search from these results.

Dealing with large amounts of data, this brings us to the question of search rankings. Lin Hong also introduced several parameters to rate the weight of these information, which greatly improved the efficiency of search.

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

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

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

When addition is solved, subtraction, multiplication, and division are naturally solved, and the operation can be completed by changing on the basis of addition.

Addition is the only thing a computer CPU does. Once this problem is solved, it is only a matter of time before other problems are solved, which can be used for mathematical operations, as well as for calculating complex ballistic parameters, and even launching satellites and controlling spacecraft.

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

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

These days, he's been working hard to construct a superbrain adder, which has led him to research CPU design and intermittently experimenting with on/off proteins to find ways for these proteins to communicate with each other.

The adder is the basis of the CPU, and the basis of the adder is the simplest of the three types of logic circuits: the AND gate, or the gate and the AND gate.

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

"Yomen" is like a very harsh referee, as long as you do a bad thing once (there is a 0 in the input), then you must be judged as a bad person, and only if you sit on a good thing twice (1), you will be considered a good person.

"Or door" is a good old person referee, his judgment criteria are relatively relaxed, as long as you do a good deed, he will recognize you as a good person, only all times you do bad things, you will be recognized as a bad person.

And the "non" door is even simpler, this referee is incompetent, always singing the opposite, you do bad things, he thinks you are a good person, and do good things, but he thinks you are a bad person.

In addition, there are some more derived gate circuits, such as AND gates, OR gates, XOR gates and three-state gates, these circuits are expanded from the most basic three circuits, and are upgraded versions of those three types of referees.

Lin Hong's first step is to find a way to create these three kinds of "referees", and he now has the basic material, which is "switch protein".

He has been studying the connection between switch proteins these days, and what he finally discovered is that they can also use fluctuations to communicate with each other, and this energy fluctuation, somewhat similar to the propagation of electrical energy, is also very fast and does not feel the delay at all.

Drawing on the experience of the last time, Lin Hong bought about three days of physical goods and drinking water from the store, and then shrank into the laboratory and did not come out.

The first step he has to do now is to use two switch proteins to construct a contrarian referee, when the state of switch protein 1 is "open", switch protein 2 must be "closed", and vice versa.

The birth of on-off proteins requires the stimulation of energy field vibration, so Lin Hong had to design a "on-off protein generator", whose function is to provide a special frequency of energy vibration to produce on-switch proteins in the brain. Lin Hong added frequency-adjustable modules to it, so that different kinds of switch proteins could be generated.

With his last experience, this time it only took him about two hours to "switch the protein generator" on and off, and it was a long process of experimentation and testing.

Five hours later, Lin Hong's face finally showed a relaxed look, and he made the first progress, finding the stimulation frequency of the "switch protein" that constructs the "contra-tune referee", and successfully connected the two switch proteins together to form the "N gate".

Two hours later, the protein material of the "Severe Referee" was also successfully found by Lin Hong, and the construction of the "and door" was successful.

An hour later, the "Good Old Referee" was successfully constructed.

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

Lin Hong did not stop, but worked hard to realize the NAND gate, the NOR gate, the XOR gate and the three-state gate.
