[70] If you don't go to the Great Wall, you are not a hero

"The Great Wall is thousands of miles long, and outside the Great Wall is my hometown, with sorghum fertilizer, soybean fragrance, and gold everywhere.

……

The Great Wall is thousands of miles long, outside the Great Wall is the hometown, 100,000 compatriots have one heart, and the new Great Wall is thousands of miles long.

……”

Hu Yiting hummed a ballad, stood on the Badaling Great Wall and looked into the distance, thinking about the eight poles and four wildernesses, the wind and clouds and the ocean, how many emperors and generals throughout the ages, and the merits were passed on to future generations.

While his heart was agitated, he shouted at the countless stacked mountains in the north on the beacon tower: "If you don't reach the Great Wall, you are not a hero, the Great Wall!

Zhang Zhuxuan has disappeared with the other leaders, and there are only Qiu Xiaoqing and Mianqiang by Hu Yiting's side.

Qiu Xiaoqing was infected by the summer beauty of the Great Wall, and when he saw Hu Yiting shouting, he also learned from him to shout to the north: "I'm here too!"

Mianqiang laughed and took out his camera to take a photo of the two.

"Hu Yiting, it's your first time coming to Beidu. ”

"Yes, Mian reporters must come often. "Hu Yiting naturally can't say that he has been here in his previous life.

Mianqiang sighed: "Yes, counting, this is the third time I have gone to the Great Wall." ”

"Tell us about your experience on the Great Wall. Hu Yiting demanded.

"I don't have any feelings, I just feel that our nation is like the Great Wall stretching and undulating, across the long river of history, across deep valleys and mountains, but today the Great Wall is useless, the world has become a global village, everyone wants to go out to see and walk, appreciate the appearance of the world. ”

Qiu Xiaoqing, with a shallow sense of wine, applauded: "What reporter Mian said is so good!"

Mianqiang said: "Since Hu Yiting asked, let's also tell me how you feel." ”

Hu Yiting looked at a matchbox-sized beacon tower in the distance, and said with emotion: "I used to think that when our nation is weak, we need something like the Great Wall to protect us.

But I later found out that after spending a hundred years and the efforts of 10,000 people, in the end, it still failed to resist the ambition and internal rot of the invaders.

In today's world, integration is accelerating, and the only way to truly protect a nation's dignity from infringement is to embrace the spirit of pioneering and enterprising.

Only in this way can the motherland be strong, and one day it will be able to make bold statements and never build the Great Wall. ”

"Well said!" Mianqiang exclaimed. "Young people want you to be so vibrant, I don't like those little old men who are dull all day long!"

"Yes, whether we want the Great Wall, how many Great Walls, and how high the walls need to be, it all depends on whether we are strong or not.

Hu Yiting, you have made me see China's future! I sincerely hope that your generation will be able to fulfill the aspirations of youth and use your boundless vitality to bring a new life and new ideals to the country and the people in the coming new century. ”

Mianqiang said excitedly, and bowed his head a little shyly: "I'm a little too excited, our generation and you can't compare, we were born in that era of explosive population growth, everyone has a bunch of brothers and sisters in the family, food, clothing, housing, medical care, education, all nervous, we also have dreams, but few people can get the resources to realize." ”

Speaking of this, Mianqiang raised his head and said: "So we pin more hopes on you, you are a qualified generation, and you deserve to do better and more successfully than us." ”

After leaving the Great Wall, Hu Yiting and his entourage met Zhang Zhuxuan and others in the parking lot on time and returned to the Beijing Office.

As soon as Hu Yiting returned to the room, he packed up, sorted out his luggage, and notified Qiu Xiaoqing.

"You're leaving tonight?"

"Leave after eating. ”

"Then I'll help you contact Secretary Tu of the Chinese Academy of Sciences. ”

"Okay. ”

"Don't you really play for a few more days? According to the schedule, there will be a scientific and technological innovation seminar attended by award-winning students from various schools tomorrow, and there will be a few days of travel arrangements, and you will not participate?"

"I don't have time to dwell on these things. ”

Qiu Xiaoqing hesitated for a while, finally nodded, and went into the room to call Tu Xiaobo.

When Tu Xiaobo heard that Hu Yiting asked to go over now, he immediately agreed, saying that he would immediately send a car to pick him up.

After eating a dinner of four dishes and one soup, it didn't take long for the car from the Chinese Academy of Sciences to come.

Qiu Xiaoqing was not at ease, and accompanied Hu Yiting all the way to the computing office.

Tu Xiaobo arranged for Hu Yiting to live in the graduate dormitory, a small gray four-story building, with rows of balconies drying all kinds of summer clothes and pants outside, and dancing in the sunset when the wind blows, like a poem of youth.

Hu Yiting was arranged to live in a room alone, Tu Xiaobo brought Hu Yiting a basin, towels, toothpaste, toothbrush, and mat, and then Qiu Xiaoqing was busy cleaning up.

"You stay first, and I'll take you to familiarize yourself with the environment and get to know some graduate students early tomorrow morning. ”

Hu Yiting shook his head: "Don't waste time, take me to see the development equipment first." From now on, I will probably only go back to the dormitory when I sleep, and go directly to the computer room to find me if I have something to do in the future. ”

Tu Xiaobo shook his head with a smile, didn't speak, and took Hu Yiting straight to the fifth computer room of the Science and Technology Building.

"You remember the road here, you go back to the dormitory in the evening, and when you turn around, I will put your ID and meal card on the table in your room, you put it away, and Teacher Xia and I will come to see you tomorrow morning." ”

Hu Yiting glanced at the equipment and found that it was a Unix workstation system supported by a 64-bit DEC-Alpha server.

Tu Xiaobo asked worriedly, "Do you know Unix?"

Hu Yiting jumped out of the graphical interface with a smile and entered a # on the screen.

Tu Xiaobo laughed: "It's me who is too careful, okay, the key to the computer room is given to you, the work manual is on the table over there, and you can find out if you have any questions, including some passwords." ”

"Teacher Qiu, I'll send you back to the guest house. ”

Qiu Xiaoqing nodded, silently patted Hu Yiting on the shoulder twice, and then turned around and left.

Hu Yiting stayed in the computer room all night, and finally had the opportunity to get in touch with the 64-bit workstation of the Chinese Academy of Sciences, and he had to get familiar with it.

After having a preliminary understanding of the system, he found the corresponding design software, opened it and immediately started to design.

The multimedia coprocessor, which was an alternative in '95, is a mess in 2015, with thousands of smartphones integrated with MMX multimedia coprocessors for video playback and 2D gaming.

The MMX instruction set coprocessor is implanted into the mobile phone ARM platform, which is also a problem that many IC design engineers in later generations can solve, and the ARM platform is still like this, not to mention the original X86 architecture.

The first thing Hu Yiting wants to solve is the problem of which MMX coprocessor to copy.

No way, it's a headache to have too many choices.

Hu Yiting finally referred to the design of some MMX coprocessors that were commonly used in later graphics cards, and directly copied them. After all, the chip on the PC is more versatile in the personal computer architecture, and it can be directly connected to the computer with the PCI interface of the graphics card in the future.

Because he was accustomed to research and development day and night in his previous life, and his body after rebirth was younger and more energetic, Hu Yiting didn't have a point to do it, and he couldn't wait to see all the Chang'an flowers in one night.

The next morning, when Tu Xiaobo came to Hu Yiting's dormitory, he opened the door and found that he was not inside, and the temporary documents and meal cards he sent last night were not moved, they were all on his desk.

"This kid can't fall asleep in the computer room, right?"

Tu Xiaobo then went to Xia Lao's office, and when he saw that Xia Lao had come, the two went to the computer room together.

When he arrived at the fifth computer room, Tu Xiaobo was stunned.

"This Hu Yiting, he won't have worked all night, right?"

Through the glass window, Xia Lao looked at Hu Yiting's thin back: "Xiaobo, do you know what the difference between a genius and a madman is?"

"I remember you said before that genius is thinking more than the average person. ”

Xia Lao said meaningfully: "A genius is actually a sober madman, there is no difference between the two, they are both the same perseverance and perseverance, they can focus on one thing for a long time, and devote themselves to selfless thinking." ”

Tu Xiaobo nodded: "I understand, because of this dedication, they always think more than ordinary people." ”

Xia Lao nodded: "You go and make breakfast and put it in the computer room." After speaking, she immediately changed her words: "Forget it, you go and get busy, I'll go to the cafeteria." In addition, you can arrange that the fifth computer room will not be open to other projects recently. ”

Tu Xiaobo sighed in his heart: "Xia Lao really values Hu Yiting, who would dare to eat in the computer room if someone else is changed." And he actually gave him an entire computer room!"

When Xia Lao entered the microcomputer room with four meat buns, four vegetable buns and a tea jar of soy milk, Hu Yiting was suddenly unaware, and was still copying the design in his mind at a rapid pace, and at the same time checking whether there was anything incompatible with this era.

When Hu Yiting clicked on the thumbnail with the mouse, Xia Lao was very surprised behind him: "What is this?

Only then did Hu Yiting realize that Xia Lao was behind him.

"Old Xia, you're here. Seeing the bun in her hand, Hu Yiting quickly got up and took it, and said gratefully: "Thank you Xia Lao for your concern, and please bring me breakfast, I'm really sorry." ”

Xia Lao opened a microcomputer next to Hu Yiting and sat down: "You hurry up and send it over, let me see what you have done this night? How can you have such progress? You have done a third of this, right?"

Oh my God, at first glance, you actually have a few cores drawn. If you're in such a hurry, can you use what you've made?"

Hu Yiting hurriedly put the bun in his mouth, operated the computer with his oily hands, and sent the design sketch to the server.

Xia Lao immediately pulled Wen Jiàn into his microcomputer, changed a pair of high-magnification glasses from his pocket, opened Wen Jiàn and pondered carefully.

"Hu Yiting, how did you set these parameters? Have you calculated them? Are the size of those command lines you remarked just right?"

"Are the source code of your functions written in C and then compiled? Or are they written directly in assembly? How can you write so many of them overnight? This function is too streamlined! It's just beautiful!"

The more Xia Lao looked at it, the more frightened she became, and she opened an auxiliary program to calculate it a little, and found that the code written by Hu Yiting was surprisingly efficient, and these mathematical languages were perfect under Hu Yiting's weaving, which made her even more amazed.

"Oh my God! Hu Yiting, what kind of high school are you going to! Hurry up and calculate your graduate studies!

As far as you work this night, it is impossible for the engineers of our computing institute to drive out so much in a month, let alone one night.

Your assembly language is so concise, every line is so beautiful, it's a work of art, how can you write it without optimization?

Hu Yiting: Did your parents graduate from the Department of Mathematics? Or from the Department of Physics?"

Hu Yiting took a sip of soy milk and said with a smile: "My parents are ordinary people. ”

Xia Lao turned his face in admiration and stroked Hu Yiting's head: "Genius...... What a genius...... Anyway, Mr. Xia, I have never seen a genius like you in my life, and today is an eye-opener......

Hu Yiting only smirked, eating the buns in a big gulp, with a happy face, as if he didn't know what a sensational thing he did last night.

Xia Lao smiled kindly and shook his head, feeling that he was still a child after all.

"You can go back to sleep later, pay more attention to rest, and when you design the core and write all the code, I will ask someone to help you wiring it." ”

Hu Yiting knew that good wiring could save him a lot of trouble when tape-out, and he already had a ready-made design in his heart, but he felt that it was difficult to resist the enthusiasm.

"Actually, I had already considered the wiring when I designed it, but it was too troublesome to do it together. I'm going to finish the core registers and general architecture first, and then it's not too late. ”

Xia Lao was so surprised that he had nothing to say, and thought to himself: "He is so omnipotent, no wonder he can't look down on the help of the computing institute! I don't understand, how can a person write code directly without calculus and deduction? You must know that this is the algorithm code written into the chip, not a word can be wrong, and a single extra byte is a waste of resources! How did he do it in one go? How did this kid's brain grow?"
