"Cheers!"

The glasses collided with a crisp sound.

Mu Qingqing poured a big sip violently, maybe he drank too quickly and choked, Mu Qingqing couldn't help but cough violently.

Pang Xuelin hurriedly poured her a glass of warm water, went up and gently patted Mu Qingqing's back, and said, "If you don't know how to drink, don't drink, come, drink slowly." ”

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

"Brother Pang, I'm fine, I drank a little bit hurriedly just now, and the beer is pretty delicious, hehe."

Pang Xuelin said: "You can't drink too much, we have to get up early tomorrow to go to the airport." ”

Mu Qingqing said: "It's okay to sleep at night, Brother Pang, you can drink with me, and then I won't see you for a long time." ”

Mu Qingqing's beautiful big eyes flickered and stared at Pang Xuelin, as if the other party was about to cry if he didn't agree.

Pang Xuelin couldn't stand her gaze, so he had to say: "That's okay, two bottles per person, you can't drink more." ”

"Hee-hee, thank you, Brother Pang."

Mu Qingqing's expression changed instantly.

Pang Xuelin couldn't cry or laugh, he lived with this girl for a month, and he also had a deeper understanding of Mu Qingqing.

This girl has a lively and jumpy personality, dares to love and hate, and often takes advantage of him.

Sometimes they will take advantage of his unpreparedness to hug him or kiss him, and the two will occasionally go out for a walk and go shopping, and they will take the initiative to hold Pang Xuelin's arm, and Pang Xuelin can't refuse if he wants to.

In fact, Pang Xuelin also understands in his heart that if this continues, the relationship between the two will change qualitatively sooner or later.

But let Pang Xuelin be ruthless and directly ask this girl to give up her illusions, Pang Xuelin couldn't do it.

There are even times when Pang Xuelin is still a little happy.

Next, the two chatted while drinking and eating.

Most of them were Mu Qingqing talking, and Pang Xuelin was just listening.

Minutes and seconds passed.

Mu Qingqing's amount of wine was a little beyond Pang Xuelin's expectations.

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

Mu Qingqing drank four bottles of beer before she was faintly drunk.

"Qingqing, you can't drink anymore, you're going to get drunk if you drink again!"

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

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

Pang Xuelin smiled.

Of course, he doesn't get drunk, and after being genetically modified with a genetic optimizer, his alcohol metabolism is so strong that it's perverted.

Even if it is fifty or sixty degrees of spirits, for him, it is no different from drinking plain water.

"Don't drink when you're dizzy, come, I'll help you to the house, and you can just sleep."

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

Finally put Mu Qingqing on the bed, Pang Xuelin went out of the house, went to the bathroom to wet and wring out the towel, and then returned to the bedroom.

Pang Xuelin couldn't help but be stunned, only to see that Mu Qingqing didn't know when she ripped off the skirt on her body, revealing her slender figure, fortunately she was still wearing underwear and did not completely walk away.

Pang Xuelin hesitated for a moment, but still stepped forward to wipe Mu Qingqing's face and body with a towel.

Finally scrubbed Mu Qingqing clean, and as soon as Pang Xuelin was about to leave, he felt that the corners of his clothes were being dragged by someone.

Pang Xuelin turned his head and saw that Mu Qingqing had woken up at some point, and was looking at Pang Xuelin drunk.

"Qingqing, what are you doing?"

Mu Qingqing's face flushed slightly, and she bit her red lip and said, "Brother Pang, ...... at night Don't leave at night, okay? ”

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

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

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

"Why?"

Mu Qingqing said with some curiosity.

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

"Out of this world?"

Mu Qingqing was stunned for a moment, and said thoughtfully: "Brother Pang, can I go with you?" ”

Pang Xuelin was slightly stunned, frowned, and said, "If you go with me, then you may have to say goodbye to everyone in this world, including your relatives and even your father." ”

Mu Qingqing thought for a while and said, "Can you bring my father with you?" ”

“……”

"It's a dangerous journey, with the potential for unimaginable accidents and even death."

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

A faint smile appeared on Mu Qingqing's face, and the sales that grabbed the corner of Pang Xuelin's clothes seemed to be pulled tighter.

"Qingqing!"

Without waiting for Pang Xuelin to finish speaking, Mu Qingqing suddenly turned over, hugged Pang Xuelin's head and kissed him heavily.

……

After a long time, the room fell silent.

Pang Xuelin leaned on the head of the bed and gently patted Mu Qingqing's smooth back: "Stinky girl, I finally got what you wanted, and now I'm satisfied." ”

Mu Qingqing hugged Pang Xuelin's body, looked up at him, and said with a smile: "Brother Pang, I gave you everything, you can't leave me in the future." By the way, you can tell me now, what do you mean when you say you're leaving this world? ”

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

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

Pang Xuelin said solemnly: "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, is this your ideal?" ”

Pang Xuelin nodded.

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

As she spoke, she slowly leaned her head over, blocked Pang Xuelin's lips again, and muttered, "Brother Pang, I still want it." ”

So, a storm broke out again in the room.

……

Early the next morning, Pang Xuelin dragged Mu Qingqing, who had not slept well, to drive directly to the airport, and then took a plane from Shencheng to Chang'an.

When he saw Mu Donglai, Pang Xuelin was a little intimidated.

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

However, Mu Donglai didn't show any special emotions, and when he saw the two holding hands, he was still relieved and laughed happily.

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

Now that the two have really come together, he will only be relieved in his heart, but he does not have the idea of his cabbage being arched 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 men, and then took Mu Qingqing to meet the third uncle and three aunts as girlfriends.

The third uncle and third aunt had already identified the relationship between Mu Qingqing and Pang Xuelin, but there was nothing special about it.

On the contrary, when he saw Chen Wenyuan, the old man blew his beard and glared, saying that Pang Xuelin would not come to school by himself, and abducted his apprentice without saying a word.

Pang Xuelin couldn't say that this old man was the old man, so he had to leave Mu Qingqing behind, and he went to see Xu Baiqing, the principal of Lan University.

"Yo, Xiaopang, what a rare guest, I didn't expect you to take the initiative to come to school."

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

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

Xu Baiqing glared at him and said, "It's also important to watch the World Cup in the United States?" ”

Pang Xuelin smiled and said: "Of course it's important, watch the World Cup once, earn hundreds of millions of dollars, and get the start-up capital for semiconductor research and development by the way, do you think it's important?" ”

Xu Baiqing was taken aback and said: "Stinky boy, you're not kidding, I made hundreds of millions of dollars in the United States this time?" ”

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

Xu Baiqing looked at Pang Xuelin for a long time before he sighed: "Lin Wazi, if it weren't for seeing you step by step to this point today, I would have doubted that you were in a dream, it's just that, maybe we old guys really can't keep up with the times, and the future of our country still depends on young people like you to develop." By the way, Transwarp's 50 million special funds have arrived, and our school has recruited more than 100 students majoring in microelectronics in the new academic year, but although our school's science is good, but the engineering is relatively weak, you might as well cooperate with Chengdian and Xidian schools to cultivate talents more conveniently. ”

Pang Xuelin said with a smile: "President Xu, what I want is the kind of science talent with a good foundation, to be honest, now our domestic undergraduate education in the field of engineering is at least 20 years behind the world's advanced level, so it is meaningless to let them directly learn the relevant knowledge in the field of engineering at the undergraduate level." It is better to concentrate on laying a good foundation in mathematics, physics, chemistry and other basic disciplines, and if the foundation is laid, they will be used in the future in both the field of engineering and the related theoretical fields of microelectronics. ”

Xu Baiqing smiled bitterly: "You, you, you have your own set of crooked reasoning, by the way, this time you will go back to Landa, how many days are you going to stay?" ”

Pang Xuelin said: "Three days, Ni Guangnan has resigned from Lenovo and is ready to defect to me, I have to hurry back to Shencheng to set up a stage for him to sing." ”

Xu Baiqing said: "It's okay for three days, tomorrow in the auditorium, remember to make a report to the new juniors!" ”

Pang Xuelin couldn't help but roll his eyes.

But there's no way around it.

Now in Lanta, he is equivalent to a mascot.

Many students who choose Lanzhou University are willing to apply to Lanzhou University in order to meet Pang Xuelin, a senior who is known as the first person of the younger generation.

Pang Xuelin naturally couldn't let them down.

Especially at the beginning of the school year, you have to cheer them up.

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

Before taking off, he got two messages.

One bad news, one good news.

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

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

For Pang Xuelin, the arrival of these people is enough to reduce his strength to form HiSilicon Semiconductor.

However, ARM's refusal was indeed somewhat unexpected by Pang Xuelin.

Pang Xuelin originally planned to acquire ARM under his command, and in the future, he will hold high the banner of ARM, occupy the market of single-chip microcomputers, industrial chips and mobile Internet chips, and become the core supplier of small terminals such as mobile phones and tablets, and then fight with Intel and AMD's X86 camp.

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

However, Pang Xuelin is not in a hurry, after all, he is a butcher Zhang, he doesn't eat hairy pigs, and without the support of ARM, Pang Xuelin is ready to independently build an instruction set architecture.

For Pang Xuelin, this is not too difficult.

In the real world, the advent of the mobile Internet has led to the rise of ARM.

In the entire Internet field, X86 and ARM have formed a situation in which they are dominant.

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

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

But in reality, there is much more to the reduced instruction set than ARM.

In the real world, in addition to ARM, the reduced instruction set also includes MIPS, Alpha, Power, SPARC, RISC-V, and so on.

MIPS is a very simple reduced instruction set architecture 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 field of architecture, for example, Patterson and Hennessy's series of books "Computer Architecture: Quantitative Research Methods" mainly takes MIPS as an example.

After purchasing the permanent license of MIPS, Hu Weiwu and his team expanded the MIPS instruction set on the basis of MIPS to form LoongISA.

Power is a RISC instruction set developed by IBM. IBM launched the world's first prototype based on RISC in 1980, and 1980 was also the beginning of IBM's dominance in the PC market, but IBM chose RISC for high-performance applications, and its success also proved that RISC has more advantages over CISC in terms of 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 for use in DEC's own workstations and servers. The Alpha is an excellent processor, not only as the first enterprise-class processor to cross GHz, but also as the first to plan for dual-core or even multi-core architectures. Following the acquisition of DEC in 2001, Compaq gradually moved its entire 64-bit server portfolio to Intel's Itanium processor architecture. In 2004, Hewlett-Packard acquired Compaq, and since then the alpha architecture has faded into obscurity.

SPARC (Scalable Processor ARChitecture) is an instruction set architecture designed by Sun in 1985 and is a very representative high-performance RISC architecture. Following Oracle's acquisition of Sun, the SPARC architecture is owned by Oracle. In September 2017, Oracle announced that it was officially abandoning its hardware business, including SPARC processors from Sun.

There is also the final RISC-V instruction set, which is an open-source instruction set architecture that follows RISC's design principles of striving for simplicity while remaining open. This open-source project originated in Berkeley in 2010.

The biggest significance of RISC-V is its open source.

Later ISAs were basically very expensive, such as the licensing of ARM.

In addition, designing CPUs is a complex and expensive task that requires not only experienced architects, but also continuous simulation, verification, and tape-out testing, which is difficult for ordinary companies to bear.

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

After several years of development, RISC-V has a complete software toolchain 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 documentation, and promoting the continued 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 started to use or plan to use the RISC-V architecture.

In addition, many textbooks in the field of architecture, such as Patterson and Hennessy's series of books "Computer Architecture: Quantitative Research Methods", are themselves strong supporters of RISC-V architecture, so more and more textbooks will use RISC-V as an example in the future.

And with the acceleration of the Internet of Things era, it makes sense to have a unified, general, open-source instruction set architecture.

However, RISC-V's ambitions are too great, and in later generations, both Intel, the king of PCs, and ARM, the overlord of mobile devices, have launched a large-scale suppression of it.
