My Return to Life

Lu Weiyu was in an extremely beautiful mood as she left the hotel humming a tune that was out of tune.

In one hand, there is an immediate limit that is not yet available in China, and two roses are sandwiched between them.

Holding Fang Nian's other arm.

Even walking became bumpy, not Mr. Lu at all.

From a car full of presents, to a cake, and a second ring delivered completely out of the blue;

Even the last two roses are very thoughtful, one pink and one white, pink represents first love, I like your bright smile; white represents humility, enough to match.

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

After walking out of the hotel, Fang Nian smiled and said, "I've made arrangements for this afternoon."

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

Then he took Lu Weiyu to the playground to play some sports that ordinary young people like.

Then Lu Weiyu dragged Fang Nian to the game hall...

When the sunset glow diffused in the sky little by little.

Lu Weiyu took Fang Nian's hand for a leisurely walk along the Pujiang River.

Talk about topics that are only about today.

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

Then he even slowed down his pace: "Is it because I took care of you?"

Fang Nian was followed and slowed down, and smiled slightly: "What's the matter, can't the little boy who is being raised be happy by himself?"

"Let you talk nonsense!" Lu Weiyu gritted her teeth and pinched Fang Nian, deliberately shook Fang Nian's hand and took two quick steps.

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

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

"Oh~"

"Be honest!"

Fang Nian: "?"

Lu Weiyu simply stopped in her tracks, 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 Wei and said: "You have observed well."

"Ming people don't say dark words. Today I am indeed proposing to Ms. Lu Weiyu who can be called 'Sister Yu'."

"And it worked."

"So I couldn't be happier."

"What's the matter?"

Seeing Fang Nian's generous admission, Lu Weiyu frowned slightly, and said 'threat', "What's going on?"

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

Lu Weiyu: "..."

"It feels like being taken care of."

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

"Anyway, I'm happy."

"..."

Lu Weiyu took Shang Nian's hand again, and walked along the Pujiang River: "OK, please, as long as you are happy."

"..."

Fang Nian couldn't explain it too clearly.

But this was really an operation he had premeditated.

It can be regarded as the marriage proposal through this special title, perfecting the biggest regret in the previous life.

Whether you deceive yourself or others, everything is fine.

Anyway, Lu Weiyu agreed.

And Fang Nian will never be able to go back to that part of his previous life, which can be regarded as a new and perfect beginning.

That's why Fang Nian is so happy.

"..."

Stepping on the sunset and returning to Junting, the happy day gradually came to an end.

Nothing to say all night.

…………

August 6th, Lunar Qixi Festival, Saturday.

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

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

After saying hello, the old man sat on the porch, watching Fang Nian and the village chief running around and around, sweating profusely, with a smile on his face.

Although she is a bit older, she also knows that exercising more is always good.

There is one exception today.

Fang Nian had just finished 10 kilometers without weight with the village head, and when he was panting heavily, Guan Qiuhe in sportswear came out humming a tune.

"Hehe, Mr. Guan actually got up so early?"

"Is the sun coming out in the west?"

Guan Qiuhe didn't care too much, and said cheerfully, "I'm happy to be able to take a half-month vacation from today, so I got up early."

"So this is ah."

"..."

So, after breakfast, Fang Nian thought about taking advantage of Qixi Festival, the traditional Chinese Valentine's Day, to call his friends over for a simple get-together.

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

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

Fang Nian took out his mobile phone and shook it.

Speaking of which, after launching the expression center function, Qingchat optimized the group chat function by the way, and the user experience is much better than before.

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

It's an obsession of Fang Nian's classmate.

Although Fang Nian didn't put Wen Ye, Lin Yucong, and Chen Qinghui in a group chat, it was more convenient than calling them one by one.

Because it was Saturday, and Fang Nian always welcomes family members, everyone responded quickly.

He said that he would come over in a while, have a lunch and get together, and he can just be free in the evening.

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

But it doesn't affect everyone's mood.

After all, everyone owns a car now, and no matter how heavy the rainstorm is, they can't get drenched.

For example, Zhang Rui, he is also Bi Fang's boss. From last year to this year, he can easily spend the money to buy an ordinary scooter.

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

In the first half of this year alone, Bi Fang signed contracts worth hundreds of millions with Frontier Science and Dangkang Games.

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

The highlight will be two months later, and 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 Qiduohua's revenue is so good. Although it showed its face at the developer conference, it is still a lot worse than Liujianfang and YY.

It means that both of them can have a marketable income through Seven Flowers.

In addition, Fang Nian was here, so I simply lent them some money to buy a scooter in full. After all, they are students, and loans are very troublesome.

Of course, everyone's cars, including Zhang Rui's, are not too expensive, less than 200,000 yuan.

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

At most, Zhang Rui should change his car next year, otherwise he would be a bit out of line with Bi Fang's CEO status, and it would be almost meaningless to go out to discuss business.

…………

…………

As Fang Nian's grandmother grew older, she gradually became more talkative.

This is a common change for most women after they enter their old age or even their octogenarian years.

To use a word that is not very pleasant to hear is called: broken mouth.

I experienced it once in the past year, and occasionally I was impatient, but when I experience it again in this life, it has a more or less friendly taste.

I am very happy to chat with the elderly.

And after Fang Nian's grandma came to apply this time, it brought about a more interesting change——

Guan Qiuhe, who can be said to hate the Tangli dialect, entered the process of accepting it inexplicably.

Acceptance, assimilation and learning.

After all, it is obviously easier for an extremely young girl to learn the Tangli dialect than for the elderly to understand and speak Mandarin.

In the living room, one old and three young people are chatting one after another.

Fang Nian's cell phone rang.

After looking at the number, Fang Nian connected the phone and said with a smile, "Academicians have a good weekend, didn't you go to celebrate with your wife?"

"Mr. Fang, I'm old and I don't have the romance of your young people anymore." Chen Jianye said with a smile.

Then he reacted: "It turns out that today is Qixi Festival, so you didn't bother Mr. Fang."

"That's impossible, no matter how busy you are, you still have time to answer the phone." Fang Nian smiled, "Academicians have something to do, but it's okay to say it."

Chen Jianye didn't talk too much nonsense, and directly talked about the business.

"Mr. Fang, it's like this. There are two things that I need to report to you. First, I will briefly report the progress of Shenlong 2;"

"Because Shenlong 2 is still based on the 28nm process, according to the current form, it can only find TSMC as an OEM, so there is no need to replace the PDK (Process Design Kit);

Secondly, referring to last year's internal chip design planning and development plan in the laboratory and this year's independent chip R\u0026D and design development outline, Shenlong 2 highlights the design concept of 1 large core + several small cores in CPU design;

At present, Shenlong 2 has basically completed all the redesign work of each unit, and is in the process of combination design and simulation verification;

The progress is slower than expected. It is estimated internally that the first actual tape-out will be carried out in early October, mainly because of the company's internal coordination strategy and cooperation with Yangcheng Zhuyan Lab's eda R\u0026D work. "

Having said that, Academician Chen Jianye paused for a while.

Then add: "In the design of the large CPU core of Shenlong 2, no modification has been made to the arm instruction set architecture, but more independent modifications have been made to its micro-architecture;①

Some execution units have been added, such as the ALU (arithmetic logic operation unit) that can execute multiplication instructions, and the creative addition of read and write units (LSU), etc.;

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

These design changes are a major item of R\u0026D expenditure of Shenlong 2, and for this reason, we specially invited on-site technical support from Synopsys and Cadence, um..."

"Zhu Yan doesn't have the technical solutions in this area yet."

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

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

"Academicians are also invited to understand from the perspective of the frontier that the coordination strategy of internal laboratories must be carried out, which 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 single-category breakthrough. "

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

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

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

"Thank you 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 and development outline, were completely written by Fang Nian.

At most, it was Wen Ye and Gu Yu who helped with formatting and proofreading.

Fang Nian really didn't know anything about chip design.

But he knew the pattern of development later.

Apple started the road of 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 led the core processing capabilities of the Android system, and was widely accepted;

In the end, arm, the provider of all mobile processing chip IP solutions, had to launch a new ultra-large core architecture of Cortex-X1.

Ok……

Apple's self-research is only a self-research on the micro-architecture, and has not done anything to the instruction set architecture.

Knowing the development pattern, and conversely through the public information and the summary reports of so many experts before the establishment of Bai Ze Lab, Fang Nian can certainly write a very effective forward-looking development outline.

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

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

After experiencing the missing parts in the last on-site meeting, it is reasonable for Chen Jianye to explain the breakthroughs of specific modules in more detail at Fang Nian's report.

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

There is one thing to say, the large-scale research and development expenditures of Baize Laboratory on Shenlong 1 and Shenlong 2 are given to some foreign companies.

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

Especially to verify the simulation tool platform system.

It is an important tool for the evaluation test before the official tape-out, and it is also called the pre-silicon evaluation test in the industry.

This kind of simulation tool platform is relatively good, and it can be so expensive that Loongson's entire company's book assets can't be used a few times.

The tools of synopsys and cadence are such.

The technical support price of a resident engineer alone is frighteningly high, 2,000 US dollars per person per day, excluding board and lodging.

In order to pursue efficiency, Bai Ze used to call a team directly from their head office, with twenty or thirty people working for half a month.

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

Some special technical requirements are not included.

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

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

The rendering CPU needs to run for several hours after a few seconds, which means that the performance is not enough, so Bai Ze has been investing in the construction of a high-performance computing platform.

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

Simulation works almost throughout the design.

After all, it is not possible to do a bit of design and go to tape-out without confirming anything. It is always necessary to carry out various verifications and tape-out after confirming that there is basically no problem.

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

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

Chip design is not to use a computer to draw two pictures, but involves a massive project. Even if the ARM public version architecture is used, there are many other technical tasks.

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

The design progress of Shenlong 2 is quite good.

Fang Nian didn't talk too much nonsense, and said with a smile: "Academician, there is some good news, tell me quickly."

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

So Fang Nian is quite looking forward to it.

Sure enough, Chen Jianye said: "The confidentiality laboratory has made some breakthroughs, but..."

Having said that, 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 the instruction set architecture that has been preliminarily completed before... There is a problem."

Chen Jianye said with some embarrassment: "We have carried out a lot of verification and revision work, and even completed the preliminary design of the micro-architecture based on this instruction set architecture, and even a certain amount of simulation work;

Turns out...it's really not suitable for small mobile devices,"

"Especially the cooperation with Godson started last month, and after some rationalization and adjustments, it has no chance to be used with mobile phones, it can only be used for computer CPU..."

Fang Nian: "!!!"

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

If the former changes, the whole system will change, which is why Wintel is so invincible;

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

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, whether the IPC performance is excellent or not becomes the difference in the performance of CPUs from different manufacturers with the same process. It is the CPU core, that is, the microarchitecture, that affects the performance of the IPC.

PS: The extra upgrades for ascension to stars mentioned earlier have all been completed, and next... anyway, we still need to ensure two updates, and we can also free up our hands to add updates. Bosses, come here~
