(This chapter says that the confusion is because Chapter 1 is temporarily blocked and merged into Chapter 2. Apply for the lifting of the ban after 2 days...)

Tick.

Tick.

Tick...

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

Stallone hung on the head of the bed, and Zhou Huimin was attached to the end of the bed. There was glass on the desk, and photos of him from childhood were pressed underneath. Against the wall of the desk was a Sanyo dual-slot recorder with a row of English tapes on it.

A little further away is the laser-310 learning machine covered with red silk cloth. His textbooks and several electronic books from childhood were placed on the bookshelf.

This is the bedroom from Su Yuanshan Middle School.

Su Yuanshan spent half an hour accepting the fact that he returned to 1991.

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

This year, Su Yuanshan was not in his seventeenth year and had just entered the first year of high school.

If he followed the trajectory, he would finish high school at No. 7 Middle School, get into the University of Science and Technology of China, then meet his wife Ye Rudai on campus, then graduate under his father, and then study at Columbia University to study for a master's degree in computer engineering. Then he joined Intel, stayed for three years and witnessed the birth of p3 to p4 and returned to China with his wife. Then he was invited by his senior brother Qin Weimin to join Guoxin, serving as the logic design engineer of Guoxin, and his wife would return to teach at the University of Science and Technology of China.

After that, he would be in Guoxin for eight years until he was exhausted and was invited to work as a simulation tool consultant at an EDA company until his senior brother invited him to join Haixin.

He has been responsible for logical design, structural design, and even microcode compilation, making Su Yuanshan the chief architect of Haixin unswervingly.

...

Su Yuanshan closed his eyes hard and buried Ye Rudai and his daughter's figures in his heart.

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

In 1991, Su Yuanshan, who was obsessed with domestic chips, was not the worst, but it was not a good one.

This year, while Intel made the final repair of 80486, he began to hold back his ultimate moves.

Because Intel canceled the x86 authorization for other "second suppliers" in the 386 era, this year, Amd and Cyrix are using the clean room "clean     room" method to make Intel curse her.

Of course, even if other manufacturers conduct white-box test reproduction in a clean room - similar to dissecting a CPU and then blindly guessing the microcode finally implements functions that are compatible with the original product - but as long as you are doing the x86 architecture, you will definitely not be able to avoid Intel's various patents under this 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 and beat up a group of counterfeit parties to the defeat - except for Cyrix, a free-spirited genius.

By the way, the CPUs of the counterfeit party are all called xx386, xx486.

Two years later, Andy Grove of Intel was so angry that he jumped up and said that if the new CPU was called 586 again, he would not 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, and only a few were successfully put into production. In addition, some high-end products were imported from China, which gave people the illusion that "it is better to buy than to make".

You know, when the domestic counterfeit Intelc8008 created the djs-050, it was only five years behind.

The 908 project, which is still in the demonstration stage, will be officially approved next year, but will stagnate due to various reasons.

Su Yuanshan remembers it very clearly that next year, one of the three giants of EDA will enter the country and crush it.

The memories are like fallen leaves filled with yellow sand. As the thoughts spread, they gradually become clear, allowing Su Yuanshan to clarify the veins.

His eyes gradually became brighter.

Crushing the panda cad?

If you have experience in using EDA software in the next 30 years, know the difficulties and pain points in using EDA, as well as the various excellent algorithms in the future, what should you do if you write an EDA?

Dimensional 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 about to arrive. He said he has brought you a gift."

"Uncle?" This title that had disappeared in my mind for a long time suddenly awakened the unpleasantness in Su Yuanshan's memory, and he couldn't help but say 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 and then to the distant northern empire, he earned millions of dollars in a few years. For this reason, Zhang Xiuyun complained a lot about her husband Su Xinghe, 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 made 100 million by reselling second-hand planes.

Zhang Ke, who had been in awe 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 one of the reasons why Su Yuanshan applied for studying abroad.

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

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!"

Su Yuanshan put on his coat and quickly opened the door.

Before leaving the door, he glanced at his mother.

My mother has just passed forty this year, with her hair full of black hair, and is leaning lazily on the sofa watching TV.

"Mom, you're so young."

"Um?"

Without caring about his mother's doubts, Su Yuanshan ran down the stairs with a smile.

——At this time, my uncle has not become the slut that everyone hates, and he is still the one who is very good to me.

Then set a small goal before developing ety and bring my uncle back.

At least I have to keep my uncle’s money.

Not long after I received my uncle, Su Xinghe also went home after the meeting. My brother-in-law and brother-in-law sat together and chatted. Su Yuanshan took the opportunity to sneak into the study and began to tinker with the computer - yes, my uncle's gift was exactly 486 in my memory.

I quickly connected the monitor and mouse, turned on the power supply, and after waiting for a while, a cursor appeared.

Su Yuanshan knew that this was the command that was very ritualistic when he entered Windows 3.0.

——win.

"A lot of memories."

Smile, shaking the clumsy trackball mouse, and clicking on the desktop menu.

As in my memory, the computer "nominally" was given to me, but the software in it was all used by my father. In addition to pascal, vc/c, there was also fortran. It seems that the person who installed the computer for Zhang Ke was also a master and knew what a computer engineering professor needed.

This 486 computer with win3.0 uses CPUs from last year's 50mz main frequency. It has added several instruction sets, which is much faster than 386, but it has castrated floating-point operations.

The memory is only 4m, there is no sound card, and there is only one 2D graphics card with ISA interface.

At this time, there is no Chinese version of Windows, and there is nothing to play except the included cards.

Su Yuanshan started c and smiled again at the ancient interface.

Back in 1991, there was enough time.

He had enough time to complete a set of advanced and considerate etha. Then he used this set of etha to knock on the door to cooperation between semiconductor companies - talking about money hurts feelings, just making friends.

Especially those semiconductor companies in Niguo have already smelled the crisis at this time and have come to China to open up new markets. You should know that in the current field of lithography machines, Nikon is the boss, and Dugu Qiubai's Asml will be a younger brother in front of Nikon in the future.

Su Yuanshan withdrew his thoughts, grabbed the notebook and pencil, and began to think about the frame.

...

The voice of my father came from behind.

“Huh?”

Su Yuanshan knew that his father and uncle had entered the study, but he did not look back, but instead looked like he was thinking hard and continued to write the library code.

In 1991, the C standard database was only proposed for two years. Not only did there be many wheels, but only major universities in China can get it.

Moreover, the compilers are not unified yet, and there are markets for turboc/c and vc/c.

Zhang Ke watched his nephew typing words quickly, thinking he was practicing English. Unexpectedly, just as he was about to greet Su Yuanshan, Su Xinghe grabbed him and approached the monitor.

Of course, Associate Professor Su knew what his son was doing.

That's why he was surprised - didn't this kid learn how to write a library by himself?
