My Return to Life

Leaving the hotel humming a little tune, Lu Weiyu was in a very beautiful mood.

With one hand, it was immediately restricted, which was not available in China, and held two roses.

Holding Fang Nian in the other hand.

It's not like Mr. Lu even when he walks.

From a gift stuffed with a car, to a cake, and a second ring that was completely unexpected;

Even the last two roses seem to be very careful, one pink and one white, pink represents first love, like your bright smile; white represents humility, and it matches well.

Lu Weiyu was so beautiful that the ends of her hair would fly.

Only when he walked out of the hotel, Fang Nian smiled and said, "I have arranged everything this afternoon."

Then Fang Nian took Lu Weiyu to the cinema to watch an old love movie.

Then I took Lu Weiyu to the playground to play some items that ordinary young people like.

Later, Lu Weiyu took Fang Nian to the game hall...

When the sunset was scattered in the sky little by little.

Lu Weiyu took Fang Nian's hand and walked easily along the banks of the Pujiang River.

Talking about topics only about today.

At the end, Lu Weiyu suddenly turned his head and glanced at Fang Nian: "Why are you happier than me?"

Then he even slowed down: "Is it because of me?"

Fang Nian slowed down after being followed, and smiled slightly: "What's the matter, can't the little white face being kept happy by herself?"

"Let you talk nonsense!" Lu Weiyu gritted his teeth and pinched Fang Nian, deliberately throwing away Fang Nian's hand two steps quickly.

Fang Nian didn't even hum, but he was still happy.

After Fang Nian followed up, Lu Weiyu leaned over again, her eyes rolling: "I remember, you were not so happy before lunch."

"Oh~"

"Tell me honestly!"

Fang Nian: "?"

Lu Weiyu stopped short and looked at Fang Nian fiercely, "What does'Sister Yu' mean?"

"You proposed to'Sister Yu' today!"

Fang Nian's eyes moved up and down quickly, looking at Lu Weiyu: "Observation is in place."

"Ming people don't talk secretly. Today, I did propose to Ms. Lu Weiyu who can be called'Sister Yu'."

"And it succeeded."

"So I'm so happy."

"What's the matter?"

Seeing Fang Nian's generous confession, Lu Weiyu frowned slightly and said ‘threatening’: "What's the matter?"

"I won't tell you." Fang Nian said hey.

Lu Weiyu: "..."

"It feels like being kept."

"Also I like this title, it seems you are older than me."

"I am happy anyway."

"..."

Lu Weiyu took the hand of Shang Nian again, and walked along the Pujiang River: "Fine, good, happy sir."

"..."

Fang Nian couldn't explain it too clearly.

But this is really his premeditated operation.

The marriage proposal through this special title is the biggest regret in my life.

It's okay to deceive yourself or others.

Anyway, Lu Weiyu agreed.

And Fang Nian can't go back to that part of his life, which can be regarded as a new and perfect beginning.

That's why Fang Nian is so happy.

"..."

Stepping on the sunset glow, I returned to Junting, and the pleasant day gradually came to an end.

No words for a night.

…………

August 6, the Chinese New Year's Eve, Saturday.

Fang Nian got up at five o'clock as usual.

Fang Nian's grandmother also gets up almost like this every day.

After saying hello, the old man sat on the porch and watched Fang Nian and the village chief ran one circle after another. His face was sweating and smiling.

Although she is older, she also knows that more exercise is always good.

There is an exception today.

Fang Nian had just finished 10 kilometers without a load with the village chief. When he was breathing heavily, Guan Qiuhe in sportswear came out humming a song.

"Yeah, President Guan actually got up so early?"

"The sun came out from the west?"

Guan Qiuhe didn't care either, and said cheerfully, "I'm happy to be on vacation for half a month from today, so I get up early."

"So this is ah."

"..."

So, after eating breakfast, Fang Nian Xunsi took advantage of the traditional Chinese Valentine's Day, Chinese Valentine's Day, and called his friends over for a simple gathering.

The last time I sat down to eat together was in the middle of last month, obviously it was summer vacation now.

Guan Qiuhe readily agreed, Lu Weiyu naturally had no objection, and by the way urged the lazy Fang Xin children to write in the small study.

Fang Nian took out his cell phone to shake the person.

Speaking of light chat, after launching the emoji center function, by the way, the group chat function has been optimized, and the user experience is much better than before.

Finally, it is very comfortable to use, without the messy functional modules of QQ group chat, and it is not the card operation of WeChat group chat.

It's an obsession of Fang Nian.

Although Fang Nian did not put Wen Ye, Lin Yucong, and Chen Qinghui in a group chat, it was more convenient than shouting one by one.

Because it is Saturday, and the family members are always welcome in the previous year, everyone responded quickly.

It means that I will come over in a while, have lunch and get together, and I will be able to move freely in the evening.

Although the Tiangong in Shencheng will not be too beautiful today, it was a little better in the morning, but now it is overcast, and there may even be heavy rain to heavy rain.

But it does not affect everyone's mood.

After all, they are all car owners now, no matter how heavy the rainstorm is.

For example, Zhang Rui, he is also Bi Fang’s boss anyway. From last year to this year or so, the money for buying an ordinary scooter can still be easily taken out.

Bi Fang has never lacked the business market. Although he has almost completely invested in research and development, it is impossible to lack wages and benefits.

In the first half of this year alone, the contract value signed by Bi Fang with Frontier Science and Dangkang Games amounted to hundreds of millions.

Although the hardware-level infrastructure is provided by the two companies themselves, all the software and maintenance of cloud computing are all resolved by the end. The contract amount can only be said to be trivial.

Two months will be the highlight. The contract value of Dangkang Games alone is estimated to be hundreds of millions.

Then there are Li Annan and Lin Yucong.

It's not that Qiduuohua's revenue is good. Although it showed up because of the developer conference, it is still a lot worse than Liujianfang and YY.

Both can have an income in line with the market through Qi Duo Hua.

In addition, Fang Nian is here, so he simply lends them some money to buy a scooter in full. After all, they are students and the loan is also very troublesome.

Of course, including Zhang Rui, everyone's car is not too expensive, and the landing is less than 200,000.

Li Annan and Lin Yucong can drive a little longer, at least they are the favorites within their respective abilities;

Zhang Rui should change the car at most next year, otherwise he would be a little bit inconsistent with the identity of the CEO of Bifang, and he would almost mean going out to discuss business.

…………

…………

Fang Nian's grandmother gradually became more talkative as she got older.

This is a common change for most women after they have entered the ancient and even old age.

It is called with a bad word: broken mouth.

I have experienced it once in the previous life, and occasionally I am not very impatient, but when I experience it again in this life, it has a somewhat cordial taste.

I am very happy to accompany the old man to chat.

And after Fang Nian’s grandmother came to Shen this time, it also brought about a more interesting change——

The general manager Guan Qiu He Guan, who hated Tangli dialect, entered the process of acceptance inexplicably.

That is, acceptance, integration and learning.

After all, compared with the elderly to understand and speak Mandarin, she is an extremely young girl, obviously easier to learn Tangli dialect.

In the living room, the young and old were chattering with each other.

Fang Nian's cell phone rang.

Looking at the sign, Fang Nian answered the phone and said with a smile: "Academician has a nice weekend. Didn't you go to the festival with your wife?"

"Fang, good, old and old, no longer the romance of your young people." Chen Jianye said with a smile.

Then he reacted: "It turns out that it's Qixi Festival today. Don't bother Fang Zong."

"Well, no matter how busy you are, you still have time to answer the phone." Fang Nian smiled, "The academician has something to do but it doesn't matter."

Chen Jianye didn't talk too much nonsense, and just started talking about business.

"President Fang, this is the case. There are two things that I need to report to you. First, I will briefly report on the progress of Shenlong 2;"

"Because the Shenlong 2 is still based on the 28nm process, according to the current form, it can only be found by TSMC, so there is no need to replace the PDK (ProcessDesignKit process design kit);

Secondly, referring to the internal chip design planning and development plan of the laboratory last year and this year's chip independent research and development design development outline, Shenlong 2 emphasizes the design concept of 1 large core + several small cores in the CPU design;

At present, Shenlong 2 has basically completed all unit redesign work, and is undergoing combined design and simulation verification;

Progress is slower than expected. The internal estimate is that the first actual tape-out will only be carried out in early October, mainly because of the company's internal coordination strategy and the factors of the eda laboratory in Yangcheng. "

At this point, Academician Chen Jianye paused briefly.

Then add an explanation: "In the design of the core of the Shenlong 2 CPU, no changes have been made to the arm instruction set architecture, but more independent changes have been made to its microarchitecture;①

Some execution units have been added, such as ALU (arithmetic logic operation unit) that can execute multiplication instructions, creatively added read-write unit (LSU), etc.;

Through simulation verification, it is optimistically estimated that read and write performance will increase by more than 50%, IPC performance will be increased by more than 20%, and power consumption will be reduced by 10%;

These design changes are a major item of research and development expenditures for the Shenlong-2. For this purpose, the on-site technical support of synopsys and cadence has been specially invited, um..."

"Zhu Wei has no technical solution capabilities in this area yet."

"This is also an important reason why it takes two months to tape out after the design has been basically completed."

After listening to Academician Chen Jianye finished speaking, Fang Nian smiled and said, "Academicians have worked hard, everyone has worked hard, and done a good job."

"Academicians are also asked to understand from a front-line perspective. The coordination strategy of internal laboratories must be carried out. This is why the frontier has established so many laboratories with a clear division of labor;

The road to independent research and development of integrated circuits cannot be a breakthrough in a single category. "

Hearing what Fang Nian said, Chen Jianye quickly said: "Fang always misunderstood, we are not complaining.

The Shenlong 1 has just been mass-produced, and it takes more time to make a breakthrough in market share. The early launch of the Shenlong 2 with more advanced performance will affect the market share of the Shenlong 1;

Personally, I have more or less deeply experienced the difficulty of not having an industrial ecology. "

"Thanks for understanding." Fang Nian smiled.

Speaking of...

The two documents, the chip design planning and development plan, and the chip independent research and development design development outline, are completely from Fang Nian.

At most, Wen Ye and Gu Yu helped with formatting and text proofreading.

Fang Nian does not understand chip design work at all.

But he knew the pattern of later development.

Apple started its independent research and development on the A6 chip, and finally tried to adopt a development route of one large core with multiple small cores, and repeatedly leading the core processing capabilities of the Android system, and then it was widely accepted;

In the end, all mobile processing chip IP solution providers arm had to introduce the new architecture of the Cortex-X1 super core.

Ok……

Apple's self-research is only self-research on the micro-architecture, not the instruction set architecture.

After knowing the development pattern, and in turn, through public information and the summary report of so many experts before the establishment of Baize Lab, Fang Nian can of course write a very effective forward-looking development outline.

Anyway, the development of companies all over the world is similar, and people who customize company strategies basically don't understand the core technology.

Fang Nian is not a special case of genius. It is nothing more than understanding the future, relying on reality, and some personal development concepts to formulate a more forward-looking development plan.

After experiencing the missing part of the last on-site meeting, Chen Jianye and Fang Nian will explain in more detail the breakthrough of specific modules.

This does not require knowledge of technology, and some proper terms are not so difficult to understand.

There is a saying that the large-scale R&D expenditures of Baize Laboratory on Shenlong 1 and Shenlong 2 are all given to some foreign companies.

For example, the synopsys and cadence companies mentioned by Jianye Chen are both excellent manufacturers of eda software, and they can provide excellent front-end and back-end integrated integrated circuit design and verification tools.

Especially the verification simulation tool platform system.

It is an important tool for pre-production evaluation and testing, and is also called pre-silicon evaluation and testing in the industry.

This kind of simulation tool platform is relatively excellent, and it can cost the entire company's book assets not to be used several times.

The tools of synopsys and cadence are such.

The price of technical support for a resident engineer alone is terribly high, 2,000 US dollars per person per day, without room and board.

In order to pursue efficiency, Bai Ze used to call a team directly from their head office, and they would work with 20 or 30 people for half a month.

Ten million yuan was gone in the blink of an eye.

Does not include some special technical requirements.

For now, the contract value of Baize Lab for these two companies has exceeded 100 million yuan.

In addition, the high-performance computing platform built to complete the simulation verification is also an investment in units of 100 million yuan.

The actual running of the rendering CPU takes a few hours for a few seconds, which means that the performance is not enough, so Bai Ze has been investing in building a high-performance computing platform.

In the near future, there are plans to cooperate with Bifang to upgrade to a cloud computing platform to save costs.

The simulation work almost runs through the design.

After all, you can’t just do a little design and then tape out without knowing anything. You always have to perform various verifications, and then tape out if you are sure that there is basically no problem.

The investment in simulation is massive, and tape-out is not cheap.

Anyway, these are the reasons why it costs so much to be better in the field of chip design.

Chip design is not about using a computer to draw two pictures, it involves a massive project, even if it is using the arm public version architecture, there are many other technical tasks.

It's just that from a fairer point of view, technical content has priority...

The design progress of Shenlong 2 is quite good.

Fang Nian didn't talk too much nonsense, and said with a smile: "Academician has any good news, hurry up and talk about it."

After all, the Baize laboratory now only has two major tasks: the research of Shenlong 2 and the confidential laboratory.

So Fang Nian is quite expecting it.

Sure enough, Chen Jianye said: "The secret laboratory has made a certain breakthrough, but..."

Speaking of this~www.ltnovel.com~ Chen Jianye hesitated.

"It can't be regarded as a breakthrough in the independent design of mobile phone processing chips. To be precise, it is an instruction set architecture that has been preliminarily completed before... There is a problem."

Chen Jianye was a little embarrassed: "We have carried out a lot of verification and revision work, and even completed the preliminary design of the microarchitecture based on this instruction set architecture, and even a certain amount of simulation work;

Eventually I found... it is really not suitable for small mobile devices,"

"Especially since the cooperation with Loongson started last month, and after some rational adjustments, it has no relationship with mobile phones. It can only be used for computer CPU use..."

Fang Nian: "!!!"

-

①: The difference between instruction set architecture and micro-architecture has been explained before. The simplest is that the former is a specification and the latter is a method;

The former has changed, and the entire system will have to change, which is why Wintel is so invincible;

The latter change mainly affects IPC (referred to as architecture performance);

List another formula: CPU performance clock frequency (MHz or GHz) × IPC (how many instructions are executed in each clock cycle of the CPU);

The clock frequency mainly depends on the production process, that is, how many nanometers; therefore, the performance of the IPC is the difference between the performance of the same process of the CPU of different manufacturers, and the CPU core, that is, the micro-architecture, affects the performance of the IPC.

PS: The extra changes to the stars mentioned before have been completed. Next...Anyway, we still have to ensure two changes. You can also free up your hands to add changes. Let the bosses come here~
