Chapter 380 Instruction Set

Feng Anbang is the eldest son of the Lin family, and he can be regarded as inheriting his father's mantle and entering the relevant departments. Pen, fun, and www.biquge.info

However, at the beginning, he had the biggest opinion on Lin Hong's family, and now it is still the same, Lin Hong didn't want to see his face at all, so he didn't follow him into the ward and continued to stay outside.

After Feng Anbang's son Feng Tianyu went in, he also came out after a while.

He is slightly older than Lin Hong, and he has now graduated from college and has begun to rely on the family's resources, just like his father, to take the road of politics.

"When did you get to the North J?" Feng Tianyu took the initiative to speak.

Lin Hong looked at him: "Yesterday." ”

This Feng Tianyu looks much more stable than before.

Lin Hong treats others, if others are friendly, he is also good to each other, and vice versa.

It's a reciprocal process. Treat others as you would like to be treated by others.

"I heard you recently started a company? Yes, I'm the boss. ”

Lin Hong said indifferently: "It's so-so, it's just a mouthful of food." ”

"So many years have passed, you disappeared in the United States for a while, I am very interested in what happened to you during that time, can you tell me a thing or two?"

"I'm sorry, I don't want to talk about the past." Lin Hong directly rejected his request.

Between him and Feng Tianyu, there is nothing to say. The two had only met once before, and although they were nominally cousins, this relationship didn't seem to be even comparable to that of strangers. If he remembers correctly, back then, he also gave the other party a punch.

Hearing Lin Hong's words, Feng Tianyu smiled and didn't mind. 《》

He continued: "Actually, I think it's not a big deal at all. After so many years, there is no point in holding on to it again. ”

Feng Tianyu had already seen these things. At that time, he was young and ignorant, and under the influence of his parents, he did not have a good attitude towards Lin Hong's family, and always looked down on them with a condescending attitude.

Over the years, however, this ridiculous notion has gradually changed after he worked. In the unit, he often encounters such people, who always have a sense of self-superiority inexplicably, and they seem extremely immature in life.

Once, in private, he heard from his immediate boss that this was a sign of ideological immaturity. If a person within the system wants to achieve something, he must correct this kind of childish behavior, and he must weigh the gains and losses in everything he does, and he absolutely cannot do anything that harms others and is not beneficial to himself. Such a person with his eyes and nostrils facing the sky, he will not dare to use it, not only will he not be able to do good things, but he may also mess things up.

Since then, Feng Tianyu has been reflecting on this behavior.

He didn't think it before, but after really looking at it, he realized that this was indeed an extremely childish and ridiculous behavior.

Despise other people and humiliate others in this posture, in addition to satisfying some perverted psychology, you will actually not get any practical benefits, but will set up opponents for yourself and create trouble. As the boss said, this is a typical harm to others and not to oneself.

It's a very serious bad habit that many people have and are completely unaware of. Only by jumping out and looking down from the sky can you see this clearly.

Since figuring this out, Feng Tianyu began to consciously change his problem. The benefits of this change are obvious, his efficiency in the unit has been greatly improved, his relationship with others has become more and more harmonious, and he has gradually been appreciated and reused by his superiors. Although he has a prominent family background, others also have it, competition is everywhere, and if he wants to climb smoothly, the role of his boss is still very great.

Now, he looked back and saw that many of his father's actions seemed very childish and ridiculous, and he had made euphemistic suggestions to his father many times, but unfortunately, his father did not listen to them at all. (《》)

He now understands why his grandparents were so opposed to his father's entry into politics in the first place.

Feng Yuanzheng and his wife have three children, and the two sons did not want them to enter politics at the beginning, and the most optimistic is their youngest daughter Feng Wan, who thinks she is the most suitable for politics. Therefore, they had high hopes for Feng Wan, but it was this little daughter that disappointed them the most, especially Feng Yuanzheng's wife, who was so angry that she went directly to the hospital, and her health was not good, which made it even worse, and she never recovered.

The second son, Feng Anguo, obeyed his parents' arrangement and entered the scientific research department.

The eldest son, Feng Anbang, did not agree to do business, and under his strong insistence, he finally entered the political arena.

After Feng Tianyu worked for a period of time, he somewhat understood the reason why his grandparents did not let his father enter politics, his personality and temper were not suitable for this environment at all, which is why after so many years, he has been staying in an idle position at the deputy department level, and basically has not moved his position.

It can be seen that Feng Tianyu wants to have a good relationship with Lin Hong, or he doesn't want to be so stiff with Lin Hong, so he said so much.

Lin Hong didn't know what his routine was for the time being, and he only answered some questions perfunctorily.

About ten minutes later, Feng Wan and Lin Changming came out of it, and judging from their expressions, it seemed that they were not very happy.

Although Feng Yuanzheng's physical condition was not as bad as he imagined, since he came, Feng Wan did not go back for the time being, but decided to stay and take care of his father first, he was usually alone in the hospital, taken care of by nurses, and he was quite lonely. As the only daughter, she is naturally obliged to serve one or two by her side.

Because it was still early, after Lin Hong sent his parents to the courtyard, he called Wu Dong, and then returned to Shuimu University again.

When Lin Hong came to the 604 dormitory, he found that Wu Dong was not the only one in the dormitory, but a tall and chubby young man.

"Boss, let me introduce you, his name is Tang Huaxin, and he is the senior brother of the School of Automation."

When Wu Dong saw Lin Hong arrive, he immediately introduced Lin Hong:

"I felt a little struggling to do this virtual machine project alone, and you weren't around, so I posted a post on the Mizuki forum and found a few interested students to study together."

For Wu Dong, the virtual machine project is indeed very large, and it has never been done before, and the efficiency of exploring alone is too low, so he started to find someone to learn together, so that any problems can be discussed together, so as to learn from each other's strengths and improve efficiency.

He posted a recruitment post in the computer section of Mizuki BBS, saying that he had launched a virtual machine project in order to learn the underlying principles of computers, and was looking forward to people with common interests and goals to join.

In the post, he described in detail the main elements of the project and the progress it has made so far.

In Mizuki, there are still a lot of cows.

After his post was posted, it attracted a lot of attention and discussion, some people said that it was too difficult and a little unrealistic, while others said that it was really good to use this method to learn the principles of computer composition.

Of course, in addition to those who talk about it, many more people go directly to dormitory 604 to actually understand the situation.

Although Wu Dong also came into contact with this project for the first time, Lin Hong had already planned for him before the basic steps, and he was basically right as long as he followed this process, so when he told others about this project, he was naturally the first to go, attracting many people to join, and finally formed a virtual machine project development team.

Of course, there are many people who are interested, but the technical level of more people is not even comparable to Wu Dong, only a few senior brothers are more reliable, and this Tang Huaxin is one of them.

Tang Huaxin is tall and chubby, and he looks honest and honest.

"Hello." Tang Huaxin greeted first.

"Hello."

Lin Hong nodded, then walked over to them, looked at the monitor, and asked:

"How's your progress? Where have you gotten to development? ”

Wu Dong said with some embarrassment: "The progress is a bit slow, and I have just begun to implement the instruction set, and I have already implemented common instructions such as add and move." ”

The instruction set he refers to refers to the language that can be understood by the CPU, each instruction set corresponds to one or more assembly languages, and after compilation, it corresponds to the machine opcode that the CPU can understand. Since they are simulating Intel's x86 architecture instruction set reminder, its implementation mechanism can be found from the int """ file.

They use a program to emulate the CPU, so the program must be compatible with these instruction sets, for example, to give the program input instruction add, it must be able to understand, this is to let it add two operands, and the operands are divided into different types such as memory and registers.

The details of the implementation are accurate to the bit, and the person who writes the virtual machine must be clear about each bit, for example, add itself corresponds to multiple different binary encodings.

To be able to understand these, basically the underlying operating principle of the computer has been very profound, which is why everyone thinks that participating in this project can be a good way to learn the principle of computer composition.

Even, after hearing about this project, some teachers in the School of Computer Science were considering whether to use this as a case to design a course, so that everyone can apply what they have learned, so that they will not just talk on paper, learn relevant knowledge, and forget it in a blink of an eye.

Fortunately, 8086 is 16 bits, its instruction set is relatively small, and the implementation mechanism is not so complicated.

However, the method used by Lin Hong is highly optimized, for example, for the conditional judgment mechanism, let Wu Dong and them realize it, and it may take at least three or four sentences to judge separately, while Lin Hong can use one sentence to do it. And this simple statement, Wu Dong and they seem, they have to think for a long time to figure out the mechanism.
