Zhang Baiqi saw that Hu Yiting was stunned, so he said: "I know you haven't seen it, you read martial arts books all day long, how can you have the kung fu to care about national affairs." ”

Hu Yiting laughed dryly: "Have you seen it?"

Zhang Baichi patted his chest: "Nonsense, last time in physical education class, I went to the dance studio with a few people to visit, oh! That woman, what a goblin! That beauty! That beautiful! That figure! That look!"

Hu Yiting hurriedly stopped: "You said that the famous flower has a master, so who is she with?"

"Our school!"

Hu Yiting became nervous and swallowed: "Who?"

Zhang Baiqi saw that Hu Yiting was serious, so he had to scratch his head: "I didn't see it either, I just heard from the second class that Lai Gangqiang said that in the past few days, Tong Mudu and a student have gone home side by side." ”

"Who's strong?"

"Coming to Gangqiang is to live in the compound of our commercial bureau, and take the car home with me all the way every day, my elementary school classmates. This is what he saw with his own eyes, and there will be no fake!"

Hu Yiting breathed a sigh of relief, it turned out that Zhang Baiqi was talking about himself.

He was originally worried that it was someone else, so he put his mind at ease.

"Your friend didn't say it, who is that man?"

He didn't dare to look closely. Zhang Baiqi paused: "Do you think, people dare to soak in school flowers, that must be a terrible master! Come to be strong, how dare you go up and take a closer look." ”

Hu Yiting coughed dryly twice: "I said, idiot, in fact, that man is me." ”

"Hahaha.................." Zhang Baiqi smirked: "Yes, slut, I also hope that the man is me." You say, how beautiful it would be to be able to come home from school with a girl like that. ”

Zhang Baiqi shook his head lyrically and sighed: "If you can wave like this, the next thing is to go out and be hit by a car and die, it's worth it." ”

Hu Yiting couldn't cry or laugh, so he had to say: "There will be such a day, I promise." ”

Zhang Baiqi unhappily pushed Hu Yiting's thigh with his knee: "you, you were hit by a car and died, it's better to be an ox cart, hit you to death, and then pee on your head." ”

"Don't run, you uncle, idiot!"

…………

After the second class in the morning, Teacher Xie from the Youth League Committee came to the fifth class of the junior high school and called Hu Yiting out.

Teacher Xie seemed to be in good spirits, and introduced to Hu Yiting downstairs in the junior high school: "Hu Yiting, this is Teacher Sun of Normal University, a judge of the computer group of the Hushan Thesis Review Committee of the National Youth Science and Technology Competition. ”

Finally finished reading such a long title in one breath, and didn't make a single mistake, Teacher Xie's expression was proud, and he then introduced to Sun Bo: "Teacher Sun, this is Hu Yiting." ”

Teacher Sun stretched out his hand and shook hands with Hu Yiting, and said with a smile: "Since ancient times, heroes have been born as teenagers, classmate Hu Yiting, do you know why I came to you?"

Of course, Hu Yiting knew in his heart: "Is there any hope for my paper to win an award?"

Teacher Sun smiled heartily: "Come, let's talk while walking." ”

Teacher Xie hurriedly said: "Then you talk, I still have some things, Teacher Sun, you want to find me when you go back, come to the Youth League Committee office on the second floor of the high school." ”

"Okay, you're busy. ”

Teacher Sun and Hu Yiting walked towards the big playground, and after a few short words, the two sides got to know each other.

"Hu Yiting, the format of your paper is very rigorous, who is your supervisor?"

"I didn't have an advisor, but I loved reading papers, especially in microelectronics and computer programming, so I wrote them like a tiger and a cat. ”

"Oh?!! there is no mentor?" Sun Bo was surprised.

It was the first time he had met a junior high school student who was interested in academic papers, and it was also a thesis in electronic science and technology. What's more, this student actually wrote such an in-depth paper without a supervisor.

"Science and engineering papers are not as good as literature, history and philosophy, although liberal arts papers also have depth, but as long as you are not illiterate, you can always understand them roughly. Since you can read professional computer papers, then your mathematical foundation should be very solid!"

"It's okay, I'm self-taught. ”

"What Cheng dù?"

"Graduate level. ”

Sun Bo was stunned for a moment, he didn't believe that Hu Yiting could learn from himself to the graduate level.

Hu Yiting also regretted it a little after speaking, and felt that he was a little reckless.

There was a silence between the two, and finally Sun Bo broke the embarrassment and said:

"It's not easy. What did your parents do?"

"My father was a copy editor at Hushan Daily, and my mother worked in the sales department of a dyeing and weaving factory. ”

"Newspaper copy editors, dyeing and weaving mills, how did you get into computers, and do such in-depth research?"

Hu Yiting stood on the edge of the big playground, bathed in the warm golden sunlight, his brain had begun to sweat, he was thinking about how to lie, but he couldn't hear the slightest weakness in his mouth:

"My tablemate Zhang Baiqi has a computer at home, and I went to his house to get in touch with it, and then I became very interested and began to find relevant books to read on my own. Well, also, my dad also has a computer in his unit, and after exposure and study, I found that the world of microelectronics is very wonderful, which is a top temple of physics and mathematics. It was in this hall that I became interested in computer instruction sets. ”

Hu Yiting simply let go and pulled down: "The processor is pre-installed with different instruction sets, with the integration of special components, to execute a certain type of special program, which can make the processor play a powerful role in various fields, so that it can be applied to different levels of production and life, such as industrial machine tools, production lines, engines, entertainment electronics, etc." ”

Mr. Sun was both surprised and happy when he heard this, and felt that he had found a very good computer seedling: "So you are completely self-taught? Have you read all the books and papers in your paper?

Hu Yiting said confidently: "Yes, I have seen it all." ”

"There are some papers in there, I can't find them in the city library, where did you read them?"

Hu Yiting raised his hand, wiped the sweat on his forehead with his sleeve, and said: "Last year, my father went to Beijing to attend a training course organized by the General Administration of Press and Publication, and I also went there during the summer vacation. ”

Hu Yiting's words were half-true, he did go to Beijing last year, but he was just traveling by visiting his father, who was participating in the study.

Sun Bo is an honest man, how did he know that Hu Yiting was a reborn demon, when he heard this, he immediately rubbed his hands and said excitedly: "That's great, interest is the key to opening the door of science and technology, you are interested, and you are willing to study, it is really rare." ”

"Thank you, Mr. Sun, for the compliment. ”

"Hu Yiting, can you guarantee that the content cited in the paper is correct? After all, you were not in Beijing when you wrote it, and many of the annotations are based on memory, so there must be deviations, right?"

Hu Yiting was very confident in his amazing memory, and said loudly: "It will never be wrong, I remember it very clearly." ”

Mr. Sun thought that blind self-confidence among young people is a common problem, and he can only verify this aspect by himself.

"Hu Yiting, I will test you, don't you mind?"

"You just say. ”

Sun Bo squatted down, picked up a small pebble from the edge of the track, and drew it on the cinder playground.

Before he finished writing, Hu Yiting had already seen that this was a sick function.

"Mr. Sun, you don't need to continue writing, this sick function is continuous everywhere and underivable everywhere, you can use Fourier analysis to find the approximate curvature, and then use Riemann integrals to find the extreme value within a certain range. ”

Sun Bo threw away the stone in his hand in surprise, stood up, and nodded to Hu Yiting with satisfaction.

Hu Yiting, I plan to recommend your paper to the province, you have to think clearly, in case your paper conclusion is wrong, or the citation is false, this will affect the results of the competition in our city. Besides, I haven't read many of these books and papers you cited, so how do you say I should write my recommendation comments?"

From the moment Hu Yiting saw Sun Bo, he had already guessed that his paper was going to be recommended, and now that it was confirmed, he was happy in his heart and pointed out:

It's easy, you just write: this is a paper that is difficult to evaluate on a general academic level, and considering that the author is a junior high school student, it is even more difficult to describe or recommend without reservation in a simple and crude generalization. Like: 'Good, not good. Yes, no. Yes and no. Totally agree, disagree. And so on.

If I have to make it clear, I can only say that as far as the current situation is concerned, looking at the overall situation of education since the reform and opening up, looking at the development of education in ancient and modern times, looking back at every important node of the science and technology competition in history, taking into account the average level of students everywhere, and analyzing and summarizing, it may be considered that in summary, we may find that although this paper may be unsatisfactory, in any case, I am afraid that this is a paper with a delicate prospect, we can only expect so, and I hope that this is the right direction of development。 But we must not rely on our limited knowledge and judgment to give science any irresponsible and debatable absolute guarantees, and the same is true for student papers. It is hoped that the higher judges will take into account the imbalance in the development of various places and give correct guidance to this paper. ”

Teacher Sun was stunned and unable to move when he heard this, and said in his heart: "Oh my God! Is this child really a junior high school student? It's just a demon! This official tone is slippery and doesn't leave his hands! Even the old man who has been in the officialdom for more than ten years may not be able to speak better." This Hu Yiting is really a wonderful, this is like playing Tai Chi, and he is not focused! If this paper wins an award in the future, this recommendation and comment can be described as thoughtful, and it is simply a solitary insight and ingenuity. However, if this paper is proved to be incorrect, or if there are inaccuracies in the quotation, this recommendation can be interpreted as a great reservation and a clear shift of responsibility! This kind of eight-sided and exquisite orthodox official tone cannot even be said by an adult like himself.

This Hu Yiting must be a demon in the future, and the future is unpredictable. ”

After Hu Yiting finished speaking, he saw Sun Bo looking at him in surprise, and suddenly came to his senses, and secretly regretted that he was frivolous because he was happy for a while, and he showed that he surpassed the normal level of junior high school students.

Hu Yiting said with a smile: "I just mentioned it, because when I saw that my father wrote letters of recommendation to other magazines and publishers for submitting articles, he probably touched this way." ”

Hu Yiting reassured Sun Bo again, and began to use his best professional knowledge and technology to convince the other party: " This kind of built-in instruction set technology, to put it bluntly, is not unusual, because the traditional personal computer CPU processor, is based on the processing of words and numbers and design, is not good at processing text and image information, usually we play games, watch videos, involving a large number of analog-to-digital conversion, that is, the conversion between analog signals and digital signals, the number of this conversion is extremely large, the signal must be pre-compressed, in order to reduce the main line load brought by transmission, and the CPU load brought by processing. ”

Seeing that Sun Bo nodded in agreement, Hu Yiting continued: "When the number jù is processed, the computer CPU will also decompress the output number jù to restore the number jù to the greatest extent.

This kind of restoration does not require complete accuracy, especially the floating-point arithmetic in the number jù processing, which is too precise for images and sounds to be meaningless, and the human eye and ears cannot distinguish the difference. Therefore, in the design algorithm, I sacrificed part of the compression accuracy in exchange for speed, otherwise the microstructure of the processor's pipeline will be overwhelmed by the huge amount of computation, and the overall performance will be reduced.

The DSP decompression card that we commonly see on the market is actually a decompression chip, and this DSP decompression card is installed on the computer, so that the CPU and this decompression chip work together to complete the processing of a large number of videos. The invention I proposed to build a multimedia instruction set into the processor is actually to integrate this DSP decompression card into the CPU.

In the past, most of the users of DSP decompression cards were TV stations or advertising agencies, and they had a large number of videos that needed to be edited and processed. However, in the future, home computers will become an important multimedia entertainment center in people's homes, and playing games, watching videos, listening to music, and multimedia processing capabilities will become the main direction of home PCs.

For a long time in the future, the main direction of microelectronics technology will not change, that is, to continuously improve the degree of integration, in order to integrate as many functions as possible, so as to improve the overall performance, so I think it is imperative to add the corresponding multimedia instruction set to the CPU.

My dissertation provides a feasible algorithm structure that enables the current CPU to use only one-third of the number of instructions required to be called in the past to complete the processing of multimedia data in a clock cycle, so as to increase the processing capacity of the CPU by 10% or even more than 40%. ”

Teacher Sun pondered what Hu Yiting just said for a long time before he came back to his senses and nodded in dismay: "That's right, I'll write your words into the recommendation comments, hand them in and try them, and finally there will be a provincial check." ”

Hu Yiting was overjoyed: "Thank you, Mr. Sun, I still have a question, if this paper can win an award, will there be a bonus?"

Sun Bo blinked, looked at Hu Yiting carefully and said, "There is no bonus." ”

Hu Yiting was suddenly in a bad mood.

"It's been in vain that I've been grinding with you for a long time, it's a pit!" he thought.

Sun Bo added slowly: "But if you want to win the award, you can add points to the high school entrance examination, if you get a ranking in the country, you can directly send to a key high school, maybe it is the high school attached to the Normal University, maybe it is the provincial first high school! If it is the first prize in the country, it is very promising to get extra points in the college entrance examination in the future, which is also an important reference for escorting the national key universities, of course, your usual grades are also very important." ”

Hu Yiting blinked, thinking to himself that I remember the future college entrance examination papers, and what else do I need to escort.

"The gaokao is too far for me. Teacher Sun, thank you for coming to see me, if there is nothing else, I will go back, and there will be classes next. ”
