The Science Fiction World of Xueba

"cheers!"

The glass made a crisp crash.

Mu Qingqing took a big gulp, maybe she drank too fast and choked, Mu Qingqing couldn't help coughing violently.

Pang Xuelin quickly poured her a glass of warm water, went up and patted Mu Qingqing's back lightly, and said, "If you don't know how to drink, don't drink it. Come on, drink slowly."

It took a long time for Mu Qingqing to recover, took the cup handed over by Pang Xuelin, and while sipping warm water, raised her head to look at Pang Xuelin, her pretty face flushed slightly.

"Brother Pang Pang, I'm fine. I was in a hurry just now, but the beer is quite delicious, hehe."

Pang Xuelin said: "It's delicious but you can't drink too much. We have to get up early to go to the airport tomorrow."

Mu Qingqing said: "You'll be fine after a night's sleep, Brother Pang, why don't you drink with me, and I won't see you for a long time."

Mu Qingqing stared at Pang Xuelin with her beautiful big eyes, as if she was about to cry if the other party refused to agree.

Pang Xuelin couldn't bear her gaze, so he said, "That's okay, two bottles per person, you can't drink too much."

"Hee hee, thank you Brother Pang."

Mu Qingqing's weeping expression changed instantly.

Pang Xuelin was a little dumbfounded, he had lived with this girl for a month, and he had a deeper understanding of Mu Qingqing.

This girl has a lively personality, dares to love and hate, and often makes small moves to take advantage of him.

Sometimes they would take advantage of his unpreparedness to hug him or kiss him. When the two of them occasionally went out for a walk or shopping, they would take the initiative to hug Pang Xuelin's arm, and Pang Xuelin couldn't refuse even if he wanted to.

In fact, Pang Xuelin also knew in his heart that if this continues, the relationship between the two will undergo a qualitative change sooner or later.

But if Pang Xuelin was cruel enough to directly make the girl give up her fantasy, Pang Xuelin couldn't do it.

Even sometimes, Pang Xuelin had a little fun.

Next, the two chatted while drinking and eating.

Mostly Mu Qingqing was talking, and Pang Xuelin was just listening.

Time passed by every minute and every second.

Mu Qingqing's drinking capacity was somewhat beyond Pang Xuelin's expectations.

One bottle, two bottles, three bottles, four bottles...

Mu Qingqing drank four bottles of beer before feeling a little tipsy.

"Qingqing, you can't drink any more, you're going to get drunk!"

Pang Xuelin drank more than Mu Qingqing, and the two of them almost emptied all the beer left by Fatty Liu.

Mu Qingqing shook her head and said, "Brother Pang Da, why aren't you drunk at all? I'm so dizzy!"

Pang Xuelin smiled.

Of course he won't be drunk, after being modified with a genetic optimizer, his ability to metabolize alcohol is so strong that it's abnormal.

Even spirits with a temperature of 50 or 60 degrees are no different to him from drinking plain water.

"Don't drink if you're dizzy. Come on, I'll help you to the house, and you'll be fine after a night of sleep."

Pang Xuelin pulled Mu Qingqing up from the chair, then hugged her shoulders, and helped her staggered to the bedroom.

After finally placing Mu Qingqing on the bed, Pang Xuelin went out of the room, went to the bathroom to wring out the towels, and then returned to the bedroom.

Pang Xuelin couldn't help being stunned, and saw that Mu Qingqing pulled off her skirt at some point, revealing her slim figure. Fortunately, she was still wearing underwear, so she wasn't completely naked.

Pang Xuelin hesitated for a moment, but went forward and wiped Mu Qingqing's face and body with a towel.

After finally scrubbing Mu Qingqing clean, Pang Xuelin was just about to leave when he felt someone grabbing the corner of his clothes.

When Pang Xuelin turned his head, he saw that Mu Qingqing had woken up at some point and was looking at Pang Xuelin with drunken eyes.

"Qingqing, what are you doing?"

A faint blush appeared on Mu Qingqing's pretty face, she bit her red lips and said, "Brother Pang Da, tonight...don't leave at night, okay?"

Pang Xuelin took a deep breath, with a bitter smile on his face, and said, "Qingqing, do you still remember what I told you in Yangcheng last year?"

Mu Qingqing blinked her watery eyes and said, "Brother Pang Da, of course I remember."

Pang Xuelin said: "I said, I can't give you happiness, I can't give you a family, I can't even give you a future! Do you know why?"

"Why?"

Mu Qingqing asked curiously.

Pang Xuelin said: "Because, one day I may leave this world in a way that you can't imagine. I'm not talking about death..."

"Leaving this world?"

Mu Qingqing was stunned, and thoughtfully said, "Brother Pang Da, can I go with you?"

Pang Xuelin was slightly taken aback, then frowned and said, "If you go with me, then you may have to bid farewell to everyone in this world, including your relatives and even your father."

Mu Qingqing thought for a while and said, "Can I bring my father along?"

"..."

"This journey is very dangerous, and there may be unimaginable accidents and even death."

"Brother Pang Da, I'm not afraid, it's a big deal, as long as I can be with you, no matter where the world is, I'm willing to follow you!"

A faint smile appeared on Mu Qingqing's face, and the salesman who grabbed the corner of Pang Xuelin's clothes seemed to be pulling even tighter.

"Qingqing!"

Before Pang Xuelin finished speaking, Mu Qingqing suddenly stood up, hugged Pang Xuelin's head and kissed him heavily.

...

After a long time, the room fell silent.

Pang Xuelin leaned against the head of the bed, and patted Mu Qingqing's smooth back lightly: "Stinky girl, you finally got what you wanted, you are satisfied now."

Mu Qingqing hugged Pang Xuelin's body, looked up at him, and said with a smile: "Brother Pang, I gave you everything, and you can't leave me behind. By the way, you can tell me now that you said you want to leave this place." What does the world mean?"

Pang Xuelin thought for a while and said, "I'm going to have money, build a spaceship by myself, and then explore other star systems."

Mu Qingqing stared blankly at Pang Xuelin, was stunned for a long time, and then burst out laughing: "That's it?"

Pang Xuelin said seriously: "Qingqing, I'm not joking with you."

Mu Qingqing got up, lay down in front of Pang Xuelin, looked at Pang Xuelin and said with a smile, "Brother Pang Pang, is this your ideal?"

Pang Xuelin nodded.

Mu Qingqing smiled and said, "Then I will work hard with you to help you realize your ideal."

As she spoke, she slowly moved her head closer, covered Pang Xuelin's lips again, and murmured, "Brother Pang, I still want it."

Then, another storm erupted in the room.

...

Early the next morning, Pang Xuelin dragged Mu Qingqing who hadn't slept well and drove directly to the airport, and then flew from Shencheng to Chang'an.

When seeing Mu Donglai, Pang Xuelin was a little scared.

After all, it's a bit too much to put someone's daughter to sleep without saying hello.

On the other hand, Mu Donglai didn't show any special emotions. When he saw the two of them holding hands, he was very relieved and laughed happily twice.

After all, he knows his daughter's thoughts better than anyone else, and he is quite satisfied with Pang Xuelin.

Now that the two are really together, he can only feel relieved in his heart, but he doesn't have the thought of his Chinese cabbage being raped by pigs.

After staying in Chang'an for two days, Pang Xuelin and Mu Qingqing took the train to Lancheng, first went to Mu Qingqing's grandparents' house to visit the two old people, and then took Mu Qingqing to meet his third uncle and third aunt as a girlfriend.

The third uncle and the third aunt had already identified the relationship between Mu Qingqing and Pang Xuelin, but they didn't express anything special.

On the contrary, when he saw Chen Wenyuan, the old man blew his beard and stared, saying that it was fine if Pang Xuelin didn't come to school, and abducted his apprentice without saying a word.

Pang Xuelin couldn't agree with the old man, so he had to leave Mu Qingqing behind while he went to see the principal of Lanzhou University, Xu Baiqing.

"Hey, Xiao Pang, what a rare visitor, I didn't expect you to come to school on your own initiative."

The first time he saw Pang Xuelin, Xu Baiqing teased.

Pang Xuelin didn't know whether to laugh or cry, and said: "Principal Xu, you also come to bury me. What I do outside is much more important than what I do in school."

Xu Baiqing glared at him and said, "Watching the World Cup in the United States is also very important?"

Pang Xuelin smiled and said: "Of course it is important. Watching the World Cup once, earning hundreds of millions of dollars, and getting the start-up capital for semiconductor research and development by the way, do you think this is important?"

Xu Baiqing was taken aback and said, "Stinky boy, are you kidding me, did you make hundreds of millions of dollars by going to America this time?"

Pang Xuelin said with a smile: "Believe it or not, anyway, half of the money I earned has already been transferred to Huawei's account, and the remaining half is going to be used to prepare HiSilicon Semiconductor."

Xu Baiqing inspected Pang Xuelin for a long time, and then said with emotion: "Lin Wazi, if I hadn't seen you step by step to where you are today, I would have doubted if it was in a dream, that's all, maybe we old guys really can't keep up The times have passed, and the future of our country depends on young people like you to develop. By the way, the 50 million special fund from Transwarp Technology has arrived, and our school has recruited more than 100 microelectronics majors in the new school year Students, but our school is good in science, but relatively weak in engineering, you might as well cooperate with schools like Chengdian and Xidian to train talents more conveniently."

Pang Xuelin said with a smile: "Principal Xu, what I want is the kind of science talents with a relatively good foundation. To be honest, our domestic undergraduate education is at least 20 years behind the world's advanced level in the field of engineering, so the undergraduate stage allows them It is meaningless to directly learn relevant knowledge in the field of engineering. It is better to concentrate on laying the foundation of basic subjects such as mathematics, physics, and chemistry. If the foundation is laid, they will be useful in the future, whether in the field of engineering or in the field of microelectronics-related theories. The land of martial arts."

Xu Baiqing smiled wryly and said, "You, you have your own set of fallacies. By the way, how many days are you going to stay in Lanzhou this time?"

Pang Xuelin said: "In about three days, Ni Guangnan has resigned from Lenovo and is going to defect to me. I have to go back to Shencheng to set up a stage for him."

Xu Baiqing said: "Three days is enough, tomorrow's auditorium, remember to give a report to the new juniors!"

Pang Xuelin couldn't help but rolled his eyes.

But this is also impossible.

Now in Lanta, he is equivalent to a mascot.

Many students who chose Lanzhou University volunteered to apply for Lanzhou University in order to meet Pang Xuelin, a senior who is known as the number one person of the younger generation.

Naturally, Pang Xuelin couldn't let them down.

Especially at the beginning of school, you have to give them encouragement.

Pang Xuelin stayed in Lancheng for five days, two days longer than expected, and then, under Mu Qingqing's reluctant eyes, boarded the plane from Lancheng to Shencheng.

Before taking off, he got two messages.

One bad news, one good news.

The bad news is that Huang Zaixing's trip to the UK failed, and ARM's boss refused to sell the company, even though Huang Zaixing had already offered a high price equivalent to twice the market value of ARM.

The good news is that after Ni Guangnan resigned from Lenovo, more than half of his team also resigned, just in time to be brought to Shencheng to work in the soon-to-be-established HiSilicon Semiconductor.

For Pang Xuelin, the arrival of these people is enough to reduce his efforts to form HiSilicon Semiconductor by more than half.

However, ARM's refusal was indeed beyond Pang Xuelin's expectations.

Pang Xuelin originally planned to acquire ARM, hold high the banner of ARM in the future, occupy the market of single-chip microcomputer, industrial chip and mobile Internet chip, and become the core supplier of small terminals such as mobile phones and tablet computers. The X86 camp hit the ring.

However, ARM's direct refusal disrupted Pang Xuelin's plan.

But Pang Xuelin is not in a hurry. After all, Butcher Zhang died, and he does not eat hairy pigs. Without the support of ARM, Pang Xuelin is going to independently develop an instruction set architecture.

For Pang Xuelin, this is not too difficult.

In the real world, ARM has risen due to the advent of the mobile Internet.

As a result, in the entire Internet field, a situation where X86 and ARM rule the roost.

X86 is mainly used on PC desktops, while ARM is mainly used on mobile terminals.

An important reason is that ARM, as a simplified instruction set, can greatly reduce chip power consumption when designing chips, and the power consumption indicator is precisely one of the most sensitive indicators for mobile chips.

But in fact, the reduced instruction set is far more than just ARM.

In the real world, in addition to ARM, there are MIPS, Alpha, Power, SPARC, RISC-V, etc. in addition to the reduced instruction set.

MIPS is a very concise reduced instruction set architecture. Its origin can be described as a famous family. It was developed by a research team led by Professor Hennessy of Stanford University. Since MIPS is a classic RISC architecture and is widely used in the teaching of architecture, for example, Patterson and Hennessy's series "Computer Architecture Quantitative Research Methods" mainly uses MIPS as an example.

The Loongson developed by Hu Weiwu is also based on the MIPS instruction set. After purchasing the permanent authorization of MIPS, Hu Weiwu and his team expanded the MIPS instruction set on the basis of MIPS and formed LoongISA belonging to Loongson.

Power is a RISC instruction set developed by IBM. IBM launched the world's first RISC-based prototype in 1980, and 1980 was also the beginning of IBM's dominance in the PC market, but IBM chose RISC for high-performance fields, and its success also proved that RISC is more powerful than CISC. It has more advantages in high performance. The Power architecture has been very successful in high-end server fields such as supercomputing and finance, and IBM is still iteratively developing the Power architecture.

Alpha is a 64-bit RISC instruction set architecture designed and developed by DEC and used in DEC's own workstations and servers. Alpha is an excellent processor. It is not only the earliest enterprise-class processor that crosses GHz, but also the earliest processor that plans to adopt dual-core or even multi-core architecture. After Compaq acquired DEC in 2001, it gradually transferred all of its 64-bit server series products to Intel's Itanium processor architecture. In 2004, HP acquired Compaq, and since then the Alpha architecture has faded out of people's vision.

SPARC (Processor ARChitecture), an instruction set architecture designed by Sun in 1985, is a very representative high-performance RISC architecture. After Oracle acquired Sun, the SPARC architecture was owned by Oracle. In September 2017, Oracle Corporation announced that it would officially abandon the hardware business, including the SPARC processor acquired from Sun.

There is also the last RISC-V instruction set, which is an open source instruction set architecture that follows the design principles of RISC, which is to strive for simplicity while maintaining openness. This open source project originated in Berkeley in 2010.

The greatest significance of RISC-V lies in its open source.

Later generations of ISA are basically very expensive, such as the authorization of ARM.

In addition, designing a CPU is also a very complicated and expensive task, which requires not only experienced architecture designers, but also continuous experience of simulation, verification, and tape-out testing, which is unaffordable for ordinary companies.

RISC-V has been designed to solve these problems since its inception, providing an open source, widely used, and verified instruction set.

After several years of development, RISC-V has a complete software tool chain and several open source processor architecture designs.

In 2016, the RISC-V Foundation was established as a non-profit organization responsible for maintaining the RISC-V instruction set manual and architecture documents, and promoting the continuous development of RISC-V.

Many well-known technology companies, such as Google, HP, Oracle, Western Digital, etc., are founding members of the RISC-V Foundation, and more and more chip companies have begun to use or plan to use the RISC-V architecture.

In addition, many textbooks in the field of architecture, such as the series of books "Computer Architecture Quantitative Research Methods" by Patterson and Hennessy, the authors themselves also strongly support the RISC-V architecture, so more and more textbooks in the future will also use RISC-V V as an example.

With the accelerated arrival of the Internet of Things era, it is very meaningful to have a unified, general-purpose, and open-source instruction set architecture.

However, RISC-V is too ambitious. In later generations, whether it is Intel, the king of PCs, or ARM, the overlord of mobile devices, they have launched a large-scale suppression of it.
