In the golden autumn provincial capital, the night breeze blows away the last trace of the autumn tiger.

Su Yuanshan held his wife's hand and walked in the alley outside the west gate of the University of Electrical Science and Technology of China in the moonlight.

Su Yuanshan and his wife met Yu Freshman. They have been together for more than 20 years. Now that their daughter is in junior high school, they still have a deep affection.

His wife Ye Rudai leaned on his shoulder. The habits over the years made the two of them completely consistent in their steps: "Brother Shan, can you Haixin stand the recent ban? If you can't stand it, you might as well come back to teach."

Su Yuanshan shook his wife's hand and a smile appeared on his face: "I want to quit, but the option has not been obtained yet. Who will support you after leaving?"

"You said this, it seems like I have become a prodigal girl raised by you." Ye Rudai glared at her husband with a gentle charm, and what she said was not the tone of an associate professor at the University of Electronic Science and Technology.

"Hehe, mainly..." Su Yuanshan kissed his wife's hair.

The breeze blew, and my wife approached his body: "I know, you said it a long time ago, and it's hard to calm down."

"Yes." Su Yuanshan sighed.

Because his father was one of the earliest teachers in microelectronics science and engineering at the University of Electronic Science and Technology of China, Su Yuanshan has heard of it since childhood and has developed a strong interest in integrated circuits.

After graduating from his father, Su Yuanshan went to Columbia University to study for a master's degree in computer engineering. After staying at Intel for three years, he witnessed the birth of p3 to p4 and returned to China with his wife. He worked as a logic design engineer for Guoxin, and his wife returned to the University of Electronic Science and Technology for teaching.

After staying in Guoxin for seven or eight years, he was exhausted and invited to Haixin. In the past few years, he has been responsible for logic design, structural design, and even microcode compilation in Guoxin. This almost omnipotent qualification has made him unswervingly become Haixin's chief kernel architect.

From the previous year to this year, the sanctions in the west have caused a dark cloud in the domestic high-end chip industry. Countless doubts and anger have caused a huge uproar on the Internet - but it has given Su Yuanshan the opportunity to come back to spend a vacation to accompany his wife.

But what?

The authorization and ecological chain of the x86 architecture are like a big iron pliers, tightly pinching the neck of the domestic desktop processor. Even without the constraints of the ecological chain and authorization, a ban also makes Haixin, a 7nm mobile Soc chip based on the arm architecture, also has no ability to resist.

Compared with intelligence, Chinese people have never been a waste.

But even if you can design a world-class architecture without the support of high-end precision manufacturing industry, it is still just a flower in the mirror and a moon in the water.

Even people can pinch you directly from the source - even etymology is not given to you.

"Now I can only take one step at a time to see if Huaxin can save the country in a curve. Otherwise..."

Su Yuanshan sighed, and at this time the headlights came from behind him, and he hugged his wife and leaned to the right.

However, the headlights approached at a crazy speed!

Accompanied by his wife's exclamation, Su Yuanshan used all his strength to push his wife away.

He flew up.

*

Tick.

Tick.

Tick...

Su Yuanshan's eyes finally left the iron alarm clock with long ears.

It took him an hour to accept the fact that he returned to 1991.

February 25, 1991, the eleventh day of the first lunar month.

This year he was under seventeen and had just entered the first year of high school.

"Dai'er, wait for me." Su Yuanshan closed his eyes hard and hid Ye Rudai and his daughter's figures in his heart.

Since you are reborn, middle-aged people don’t need sentimentality.

1991? For Su Yuanshan, who is obsessed with domestic chips, it is not the worst, but it is not a good one.

This year? While Intel made the final fix for 80486, he started to hold back his ultimate moves.

Because Intel canceled the x86 authorization for other "second suppliers" as early as the 386 era, Amd and Cyrix have been using the clean room "clean      room" method to make Intel curse her.

Not to mention the copycat? Everyone also hangs the signs of 386 and 486.

Of course, even if other manufacturers can perform white box test reproduction through clean     room—similar to dissecting a CPU?          Blind guessing the microcode finally implements functions that are compatible with the original product—but as long as you are doing the x86 architecture?                                                                                

The most notorious one is the Crawford patent ('338) patent), which is a patent for memory management and cache, and it is said that no one can bypass it under x86.

Thanks to this, Intel wielded the patent stick? I won’t say much about the counterfeit party to defeat the army - except for Cyrix, a free-spirited genius.

Two years later? Andy Grove of Intel was so angry that he jumped up and said who would use 586 to step on my body, so the pentium was born.

——Lights, waiting for lights.

In contrast, at this time, everything was in trouble. In the 1980s, dozens of semiconductor production lines were introduced in China? But they were confused by the so-called "honeymoon period" and fell into the naive trap of "it is better to buy than to make".

You know? At that time, when the domestic copycats released 8086 microcontrollers, they were only five years behind.

And the 908 project that is already underway?                                                                                                                         

Although the following 909 project learned from the pain, the time was just stuck in the last highlight of diplomatic relations in the 1995, the 1990s? No one expected that it would be "arranged" the next year.

Vassenal? This shameless agreement? It began to encircle Xia Kingdom for 30 years.

All equipment from the most basic eda (integrated circuit design software) to the last flow strip are all arranged. A wafer factory needs more than just a lithography machine.

Su Yuanshan remembers it very clearly that next year, one of the three giants of EDA will enter the country and launch a "dimensionality reduction strike".

...

The mother's call interrupted Su Yuanshan's thoughts.

"Small Hill."

"Hey, mom." Su Yuanshan wiped his face and replied with a smile.

"Check it out quickly and go downstairs, your uncle is coming soon."

"Uncle?" This title that had disappeared in his mind for a long time suddenly awakened the unpleasantness in Su Yuanshan's memory. He said in a deep voice: "What are he doing?"

Su Yuanshan's uncle was Zhang Ke. In the 1980s, he was an amazing talent in the family. He and a group of people became dissidents. From south to north to the distant northern empire, he earned millions of dollars in a few years. For this reason, Su Yuanshan's mother Zhang Xiuyun muttered about her husband Su Xinghe a lot, complaining that her husband was not as good as a speculative man to make more money as a professor.

To be fair, my uncle is not the kind of old man who just makes money. He has always respected his brother-in-law, and once gave a Wave 486 to Su Yuanshan's father.

But everything changed after Zhang Ke met the great man who was reselling second-hand planes soared into the sky.

Zhang Ke, who had been respectful of knowledge before, became arrogant and entered the futures market under the guidance of that great man, but ended up losing all his pants.

Later he found Su Yuanshan's mother, Zhang Xiuyun, the "brother-supporting demon" in later generations, believed the lies of his younger brother's words of "repaying his principal for a month at most". He gave all the savings in his family to his younger brother, and embezzled 100,000 public funds.

The result can be imagined...

Associate Professor Su Xinghe was so anxious that he almost turned gray all night, asking people everywhere to borrow money to fill the holes.

Although this matter was not discovered in the end, there was no peace in the family since then - this is also the reason why Su Yuanshan applied for studying abroad.

After that, my uncle was in a slump and became a scoundrel who was cheating and lies.

Su Yuanshan's tone surprised Zhang Xiuyun. Zhang Ke has always been very good to Su Yuanshan, and his son has always liked him, his uncle. Did this kid take the wrong medicine today?

Just as Zhang Xiuyun was about to curse, he became surprised when he heard Su Yuanshan's tone.

"Is it my uncle? I'll go down and pick him up!" - At this time, my uncle has not become the lazy person who everyone hates, and is still the energetic uncle.

...

"Xiaoshan." My uncle Zhang Ke held two cardboard boxes and greeted his nephew.

"Uncle, you're walking fast. Why didn't my aunt come?" Su Yuanshan took a step forward. He stretched out his handshake habitually, but suddenly came back to his senses and helped his uncle move the box with a smile.

"I'm back to my parents' home. Be careful with your gift. Guess what it is?"

Su Yuanshan said: "Computer."

Zhang Ke looked surprised: "Huh? How did you guess? I didn't even say your mother."

“It says, wave.”

"You kid, you are worthy of being your brother-in-law's son, you are smart enough!" Zhang Ke patted Su Yuanshan's head docilely, and walked towards the family building with a big box in his arms.

Now my uncle, who is just in his early thirties, is full of energy, but he cannot tell at all that he is a "rich man" who has made millions of dollars. On the one hand, this is because of family tutoring. On the other hand, my uncle does not think he is too awesome, and he still respects knowledge and science.

"Let's go? Why do you see that the computer can't move your legs?"

Su Yuanshan smiled and said, "No, thank you uncle."

The uncle shook his leather bag casually, revealing his big brother's antenna: "Well, you should have lost your apple long ago. I heard people say it was an old antique from more than ten years ago."

"But although this one looks a bit old, it has the latest 486 plus the latest system inside." My uncle turned around and showed Su Yuanshan a proud look: "Specially customized!"

Su Yuanshan, who has used this computer for many years, couldn't help but feel silent.

The so-called customization is actually the second-hand ones that his friends who make computers are rushing...

But even so, this one will have to come out of ten thousand, which is considered a gift that is so heavy that it cannot be more heavy.

Thinking of the disgust for my uncle in my memory, Su Yuanshan exhaled.

Then set a small goal first and pull my uncle back.

Chapter 2

Not long after his father Su Xinghe came home after the meeting, his brother-in-law and brother-in-law sat together and chatted, and Su Yuanshan took the opportunity to sneak into the study and began to tinker with the computer.
