MTL - The Science Fiction World of Xueba-Chapter 472 Instruction Set

"Cheers!"

The glass made a crisp collision.

Mu Qingqing swallowed a big mouthful, perhaps because he drank too quickly and was choked, Mu Qingqing couldn't help coughing violently.

Pang Xuelin quickly poured a glass of warm water for her, went up and gently patted Mu Qingqing's back, and said, "Don't drink if you don't drink, come, drink slowly."

It took a long time for Mu Qingqing to come over and take the cup handed over by Pang Xuelin. While holding the warm water, he looked up at Pang Xuelin, his face flushed faintly.

"Huge brother, I'm okay. I drank a little bit anxiously just now, and the beer is quite delicious, hee hee."

Pang Xuelin said: "Don't drink too much, we have to get up early at the airport tomorrow."

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

Mu Qingqing stared at Pang Xuelin with big beautiful eyes, as if the other party wouldn't agree and would cry.

Pang Xuelin couldn't bear her gaze, so she said: "That line, one person and two bottles, can't drink more."

"Hee hee, thank you huge brother."

Mu Qingqing's expression of crying suddenly changed.

Pang Xuelin couldn't help crying and laughing, and lived with the girl for a month. He also had a deeper understanding of Mu Qingqing.

This girl has a lively personality, dare to love and hate, and often take small actions that take advantage of him.

Sometimes he would take advantage of him when he was not prepared, hug him or kiss him. The two occasionally went out for walks and shopping, and even took the initiative to take Pang Xuelin's arm. Pang Xuelin could not refuse if he wanted to refuse.

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

But let Pang Xuelin ruthlessly let the girl give up the fantasy directly, Pang Xuelin could not do it.

Even sometimes, Pang Xuelin has some fun.

Next, the two ate and drank while chatting.

Most of them are Mu Qingqing talking, Pang Xuelin just listening.

Time passed by one minute and one second.

Mu Qingqing's wine volume was somewhat beyond Pang Xuelin's expectations.

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

Mu Qingqing drank four bottles of beer, only to faintly get drunk.

"Qingqing, you can't drink anymore, you're drunk again!"

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

Mu Qingqing shook his head and said, "Huge brother, why are you not drunk at all? I'm so dizzy!"

Pang Xuelin smiled.

Of course, he will not be drunk. After genetic modification, his alcohol metabolism is so strong that he is abnormal.

Even hard liquor at 50 or 60 degrees is no different to drinking boiled water for him.

"Don't drink when you are dizzy. Come, I will help you to go to the house. You just sleep."

Pang Xuelin dragged Mu Qingqing from the chair, then wrapped her shoulders and helped her to go to the bedroom.

Finally, Mu Qingqing was placed on the bed. Pang Xuelin went out of the room, went to the bathroom to wet the towel and wringed it, and then returned to the bedroom.

Pang Xuelin couldn't help but see, Mu Qingqing didn't know when she pulled off the skirt on her body, revealing her slim figure. Fortunately, she was still wearing underwear and didn't completely disappear.

Pang Xuelin hesitated for a while, or stepped forward and wiped Mu Qingqing's face and body with a towel.

Finally, Mu Qingqing was scrubbed clean, Pang Xuelin was just about to leave, and he felt that his clothes corner was being dragged.

Pang Xuelin turned his head and saw that Mu Qingqing did not know when she had woken up and was looking at Pang Xuelin in a dizzy and confused way.

"Qingqing, what are you doing?"

Mu Qingqing had a faint blush on her pretty face, biting her red lips and said, "Huge brother, at night ... I won't go at night, will you?"

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

Mu Qingqing blinked his watery eyes and said, "Of course, I remember the huge brother."

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

"why?"

Mu Qingqing said somewhat curiously.

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

"Leave this world?"

Mu Qingqing froze for a while, thoughtfully: "Huge brother, can I go with you?"

Pang Xuelin froze for a moment, frowning: "If you go with me, you may have to say goodbye to everyone in this world, including your loved ones, and even your father.

Mu Qingqing thought for a while and said, "Can I take my dad too?"

"..."

"This journey is very dangerous, and it may encounter unimaginable accidents or even death."

"Huge brother, I'm not afraid, big deal, as long as I can be with you, no matter where I am, I will be willing to follow you!"

A light smile appeared on Mu Qingqing's face, and the sales that grabbed Pang Xuelin's clothing corner seemed to be tighter.

"Qingqing!"

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

...

After a long time, the room became quiet.

Pang Xuelin leaned against the head of the bed and gently patted Mu Qingqing's smooth back: "Smelly girl, finally let you get what you want, now you are satisfied."

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

After thinking for a while, Pang Xuelin said, "I am ready to have money, build a spaceship myself, and then explore other stars."

Mu Qingqing stared at Pang Xuelin blankly for a long time before he laughed out loud: "Just this?"

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

Mu Qingqing got up and lay down in front of Pang Xuelin, looking at Pang Xuelin and laughing: "Huge brother, is this your ideal?"

Pang Xuelin nodded.

Mu Qingqing smiled and said: "Then I will work with you to help you achieve your ideals."

With that said, she slowly gathered her head and blocked Pang Xuelin's lips again, murmured: "Huge brother, I still want it."

So, a storm ignited again in the room.

...

Early the next morning, Pang Xuelin dragged Mu Qingqing, who didn't sleep well, directly to the airport, and then flew from the deep city to Chang'an.

When he saw Mu Dong coming, Pang Xuelin was a bit wary.

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

However, Mu Donglai did not show any special emotions. When he saw the two holding hands, he was still relieved and smiled happily.

After all, his daughter's mind is clearer than anyone else, and he is quite satisfied with Pang Xuelin.

Now that the two have really come together, he will only be relieved in his heart, but he has no idea of ​​his Chinese cabbage being swallowed by pigs.

After spending two days in Chang'an, Pang Xuelin and Mu Qingqing took a train to Lancheng. They first went to Mu Qingqing's grandparents' house to meet the two old men, and then took Mu Qingqing as a girlfriend to meet the three uncles and aunts.

Aunts Three and Three have long recognized the relationship between Mu Qingqing and Pang Xuelin, but they have nothing to say.

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

Pang Xuelin said that the old man had to leave Mu Qingqing, and he went to see President Xu Baiqing of Lan University.

"Yo, Xiao Pang, it's a rare guest. I didn't expect you to come to school on your own initiative."

Seeing Pang Xuelin for the first time, Xu Baiqing teased.

Pang Xuelin couldn't help crying and said, "Principal Xu, you come to bury me too. What I do outside is much more important than in school."

Xu Baiqing glared at him and said, "Is it important to watch the World Cup in the United States?"

Pang Xuelin smiled and said: "Of course it is important. Watching a World Cup and earning hundreds of millions of dollars, by the way, got the start-up funds for semiconductor research and development. Do you say this matter is not important?"

Xu Baiqing was taken aback by saying: "Sordy 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 have earned has been entered into Warwick's account, and the remaining half, I am going to use to prepare for HiSilicon."

Xu Baiqing examined Pang Xuelin for a long time, and then said with emotion: "Lin Wazi, if you didn't see you step by step to today's level, I wonder if it's in a dream, okay, maybe we old guys really can't keep up The times, the future of our country, must be developed by young people like you. By the way, the 50 million special fund of Xinghuan Technology has arrived. Our school has recruited more than 100 microelectronics professionals Students, although our school ’s science is good, but engineering is relatively weak, you might as well work with schools such as Chengdian and Xidian to make it easier to train talent. "

Pang Xuelin said with a smile: "Principal Xu, what I want is the kind of science talents with a good foundation. To be honest, now our domestic undergraduate education is at least 20 years behind the world's advanced level in engineering, so the undergraduate stage let them It is meaningless to directly learn relevant knowledge in the field of engineering. It is better to concentrate on the foundation of basic disciplines such as mathematics, physics, and chemistry. The foundation is laid. In the future, whether in the field of engineering or in the related theoretical fields of microelectronics, they have their use. Land of Martial Arts. "

Xu Baiqing smiled bitterly: "You, you have a set of your own distortions. By the way, this time when you go back to Lanta, how long are you going to stay?"

Pang Xuelin said: "In three days, Ni Guangnan left Lenovo and was ready to rush to my side. I have to go back to the deep city to sing for him."

Xu Baiqing said: "You can do it in three days. Tomorrow in the auditorium, remember to give a report to the new students!"

Pang Xuelin couldn't help rolling his eyes.

But this is also impossible.

Now in Landa, he is equivalent to a mascot.

A lot of students choose Lanzhou University in order to see Pang Xuelin, who is known as the first-generation senior of the younger generation, and then report their volunteers to Lanzhou University.

Pang Xuelin can't let them down.

Especially at the start of school, they have to be encouraged.

Pang Xuelin stayed in Lancheng for five days, which was two days longer than expected. This made Mu Qingqing reluctantly board the plane from Lancheng to Shenzhen.

Before taking off, he got two news.

One bad news, one good news.

The bad news is that Huang Zaixing's trip to the United Kingdom failed, and the boss of ARM 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, his team also resigned for more than a half, just to be able to take to the deep city and enter the work of the upcoming Hisilicon semiconductor.

For Pang Xuelin, the arrival of these people is enough to make him less than half the effort to form Hisilicon.

But ARM's refusal is indeed somewhat beyond Pang Xuelin's expectations.

After Pang Xuelin was originally planning to acquire ARM under his command, he will hold the banner of ARM in the future, 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 tablet computers. Of the X86 camp.

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

However, Pang Xuelin was not in a hurry. After all, Zhang Tufu died, did not eat a pig with hair, and did not have the support of ARM. Pang Xuelin prepared to build an instruction set architecture by himself.

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.

So that in the entire Internet field, the formation of X86 and ARM respectively dominate the situation.

X86 is mainly used in PC desktops, while ARM is mainly used in 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 precisely one of the most sensitive indicators of the mobile terminal chip.

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

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

MIPS is a very simple and streamlined 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. Because MIPS is a classic RISC architecture, and is widely used in the teaching of architecture, such as Patterson and Hennessy's series of "Computer Architecture · Quantitative Research Methods" mainly take MIPS as an example.

Hu Weiwu's Loongson is also based on the MIPS instruction set. After purchasing the permanent authorization of MIPS, Hu Weiwu's team expanded the MIPS instruction set on the basis of MIPS to form LoongISA belonging to Loongson.

Power is the RISC instruction set developed by IBM. IBM launched the world's first RISC-based prototype in 1980, and 1980 was also the starting period for IBM to dominate the PC market, but IBM chose RISC for high-performance areas, and its success also proved that RISC is better than CISC. More advantages in high performance. The Power architecture has been very successful in high-end servers such as supercomputing and finance. To date, 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 processor that crosses the GHz, but also the earliest plan to adopt dual-core or even multi-core architecture processors. After Compaq acquired DEC in 2001, it gradually transferred all 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 perspective.

SPARC (ProcessorARChitecture), 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 announced the formal abandonment of its hardware business, which also included SPARC processors acquired from Sun.

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

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

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

In addition, designing a CPU is also a very complicated and expensive task. It requires not only experienced architects, but also continuous experience in simulation, verification, and tape-out testing, which is unbearable for ordinary companies.

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

After several years of development ~ www.novelbuddy.com ~ has a complete software tool chain, and several open source processor architecture design.

In 2016, the RISC-V Foundation was established. As a non-profit organization, it is 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, Hewlett-Packard, 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 Patterson and Hennessy's series "Computer Architecture · Quantitative Research Methods", the authors themselves also strongly support the RISC-V architecture, so more and more textbooks will follow V as an example.

With the acceleration of the Internet of Things era, it makes sense to have a unified, universal, open source instruction set architecture.

However, RISC-V's ambitions are too large. In the later generations, whether it is the king of PC Intel or the overlord of mobile devices, ARM has launched a large-scale suppression of it.
