Rebirth 2010, the best

Chapter 269 This chip is not good

Lu Yao rarely told his mother what he was doing.

I didn’t want to say it before, I thought it was unnecessary, but now I have to say it.

Because plans cannot keep up with changes, he has to show his parents what he is doing in some aspects so that they... don't have to worry so much in the future because of some situations he encounters.

The simplest explanation is money.

It can only be money.

Otherwise he would say to his mother, “Mom, I’m currently conducting research on a top-secret project, and there are spies contacting me. You and my dad should be careful.” Ms. Chen’s blood pressure would probably have risen to 180.

Therefore, it is easiest for your family to accept if you start by taking it step by step and starting the change by making money.

But he never had the chance to tell his mother.

And today just happened to be the day, so he just told the truth.

Say it out loud and let your mother accept it slowly.

Does Ms. Chen accept it?
She couldn't accept it.

What the hell...it raised more than 20 million yuan?
The thing that a group of people riding electric bikes carry boxes on their backs every day, was made by my son???
"you……"

She was a little stunned for a moment. She had a lot of questions but couldn't ask them. She even felt a little dizzy.

Seeing this, Lu Yao did not urge them, but just drove the car to the vegetable market.

Ms. Chen said the first sentence:

"Don't let anyone scratch your car."

"No, this car has a car cover."

After hearing this, Ms. Chen got out of the car.

After her son habitually held her hand, she was stunned... After unconsciously looking up at her son, she suddenly felt that most of the thoughts in her mind disappeared.

"Sister Chen, come buy some groceries... Oh, isn't this Lu Yao? He's so handsome!"

She is an old customer and many people at the stalls here know her.

While greeting, they saw Lu Yao and smiled warmly.

Lu Yao responded politely.

Ms. Chen also started buying food to cook for her son at noon.

She originally wanted to stir-fry some loofah, but Lu Yao pointed at the tomatoes:
"Mom, I want to eat tomato and eggs."

"Don't pick...you don't know how to choose."

Seeing her son pick up a tomato that was somewhat dark red in color, Ms. Chen took it away speechlessly. Just like when they were children, she put the tomato back in its place and pulled her son back slightly.

The result was no pull...

Only then did she realize that the child was no longer the little guy who followed her around when she was little.

He looked at Lu Yao again, then looked away, and with the unique vision he had acquired over twenty years, he picked out two of the freshest tomatoes and handed them to the stall owner.

Then she looked around and asked:
"Can't you eat the loofah?"

"No, I want potatoes... Put potatoes in the ribs..."

So she picked two more potatoes.

But considering that two dishes would definitely not be enough for two people, he asked someone to cut two yuan worth of winter melon and planned to go home and cook some soup.

Finally, I took a handful of green onions and two cucumbers.

After paying the bill, he took his son and walked directly to the meat stall.

After buying four ribs, she bought some junk food speechlessly at Lu Yao's instigation.

It is the fried chicken fillet sold at the cold dish stall.

A winter melon soup, a roasted pork ribs, a tomato and egg, and finally a cold cucumber.

It's definitely enough for lunch.

The snack is fried chicken fillet.

The things in the vegetable market are fresh. Carrying a bag of things, the two walked out and got into the car again.

After Lu Yao turned the car around and was walking back, he saw that his mother didn't say anything, so he took the initiative to ask:

"Mom, what are you thinking about?"

"Would you like to buy some more chicken wings? It's been a while since I cooked chicken wings for you, right?"

"Well……"

Lu Yao thought for a moment and shook his head:
"Let's not eat anymore. Four dishes are enough...Aren't you going to ask me about my company?"

"I wanted to ask at first, but then I thought it was unnecessary."

While buying vegetables, Ms. Chen, whose doubts had mostly dissipated, seemed very calm:

"You've grown up. I don't understand the things you young people use now. For example, mobile phones... and takeout. Mom is old."

"No... I'm still young."

"Just your sweet mouth."

Ms. Chen smiled and shook her head. She leaned back in the comfortable seat of the Bentley and looked out at the street that had changed a lot after walking for who knows how many years, yet still seemed the same. She suddenly said:
"You will be the mainstay of the family from now on, do you understand?"

"Uh……"

"Don't learn bad habits... Even if the company makes money, you can't spend it lavishly. The amount of money a person earns in his life is limited. Once you earn it and spend it, it's gone. Don't you understand?"

Listening to his mother's words, Lu Yao thought for a moment and said with a smile:

"I would like to tell you more about my company."

But Ms. Chen gave a wrong answer:
"What did your sister talk to you about?"

"Didn't I just say that?"

"I didn't really listen to her just now. What was she going to do?"

So, on the way back, the mother and son talked mainly about Lu Qing.

After all this back and forth, Chen Aihua suddenly felt relieved when she saw that her son had actually started to manage the household.

It’s amazing that my son seems to have grown up overnight and become sensible.

It gave her the illusion that it wasn't real.

However, after gradually calming down, she began to care about her son's company again.

Lu Yao thought to himself that you change your mind so quickly, old man. Just now you said you didn't understand, but now you start talking about these things after we just finished our meal.

So, he explained these things in detail again, and after Ms. Chen was sure that her experience was useless and she could not do anything, she chose to believe her son.

Anyway...my son is very outstanding.

Excellent and sensible.

As parents, we just need to maintain an open-minded attitude towards such matters.

……

Lu Yao stayed at home for two days. Since his mother was transferred to another job, it became a regular activity for her to see her son on Saturdays and Sundays and cook for him.

And he went to school on Sunday night.

First, the people in 305 held a meeting. Then, after spending a whole day fishing in the laboratory on Monday, the two of them went directly to the airport early in the morning on Tuesday.

After the senior helped him change the ticket, Lu Yao realized...

"Business class?"

"Yes."

Bai Yao nodded:
"It seems like Huawei's treatment is pretty good."

"No, you should say that the tutor's salary is good, or very high. After all, considering the academic average of semiconductor practitioners, graduate students don't even get to sit first class."

Lu Yao said, with some emotion...

When he was a graduate student in his previous life, his supervisor would take them to meetings and the like, and several of them would have to squeeze into economy class.

The first time he enjoyed the privilege of flying business class was when he started his doctoral studies and was responsible for the research and development of related chip projects under his supervisor.

But judging from the business class treatment, the status of the tutor is obviously much higher in HiSilicon's central laboratory. Of course, having said that, in fact, being able to work in the laboratory must be better than the researchers in other research laboratories of HiSilicon.

The central laboratory is HiSilicon's most important and top laboratory.

Unfortunately, the identities of all researchers in the HiSilicon Center laboratory, whether they are formal or specially appointed as tutors, are kept confidential. Unless they reveal it, outsiders will have no idea.

When he first followed his mentor to Shenzhen, he also squeezed into economy class.

Gee...

With a little feeling of how things have changed and how people have changed, Bai Yao said:
"I was looking at the Pacific website yesterday. Some media had obtained some information saying that Huawei is developing a new mobile phone chip and has learned from the lessons of K3V1... The performance will be improved across the board. This is what a Huawei engineer said in an interview. Have you read the article?"

"No." Seeing that Lu Yao hadn't seen it, she thought for a moment and asked:

"You said... the Huawei K chip that the instructor mentioned, could it be this new chip?"

"It's hard to say. When did you see this article?"

"Last night. While you were sleeping."

"…You were the one who said you were sleepy and asked me to turn off the lights. You mean I fell asleep but you are still awake?"

"I can't sleep again."

Senior sister Leng Yan, who was 1.8 meters tall and looked very powerful, shrugged casually:

"Who told you to let me coax you to sleep?"

"You mean you blame me?"

Lu Yao rolled his eyes and continued to ask:

“Was that article published yesterday?”

"Yes, yesterday afternoon."

"Then you can ask the instructor later."

"…How can I ask? This is confidential."

Seeing her so naive, Lu Yao rolled his eyes:

"Think about it. Since this chip has appeared in the media, and the media has even interviewed Huawei engineers, it means... at least all the difficulties in its work have been resolved, and the progress has reached more than 90%. Otherwise, Huawei's people would not tell others that they have developed a new chip. This kind of research and development is confidential. Without the authorization of the headquarters, who dares to talk about it? And which media can interview it? Therefore, as long as there is news, it means that it must be almost completed, and it may even have been leaked."

"so?"

Bai Yao still looked puzzled.

Lu Yao shrugged:

"So, you can just ask your supervisor about the article and ask the media whether the article is what he is currently researching."

"Well, I still don't quite understand. Why don't you ask?"

"What's this...huh?"

Suddenly, Lu Yao reacted and looked at her abruptly.

The senior student still had a cold face.

But Lu Yao understood her micro-expression:

"You're using me as a scapegoat, huh? Can you be more cunning?"

"He who can do it should work harder."

"I don't believe you."

He shook his head, took out his phone and handed it to her:
"Find the article."

You really need to ask.

Strictly speaking, K3V1 was actually developed last year. However, it is only this year, on the 9th of next month, that Huawei will launch the first mobile phone equipped with K3V1, a very low-end chip. It is also the first mobile phone of "Huawei Honor".

Like the first mobile phones of all new brands, Honor U3 equipped with K1V8860 is a product for the low-end mobile phone market, firstly to seize the market and fight a price war. Secondly... this is HiSilicon's first chip, a preliminary attempt in the processor field.

It wasn't a very successful model.

This also led to Huawei being labeled as "cheap" at the time, and it took several years to clear itself of the label.

I don't know whether it is not worth the loss from a business perspective.

The development of K3V2, at least when Huawei announced it, was in May 12. At that time, Huawei announced some parameters, such as the industry's smallest quad-core A5 architecture processor, a high-performance CPU, and twice the memory bus of Nvidia's TEGRA9.

Wow...the domestic media went crazy.

This processor is highly praised. To use the most fashionable words, it is truly "surpassing the world's advanced level."

As a result, in January 13, when the Ascend D1 mobile phone came out, everyone was stunned.

The VIVANTE GPU architecture has extremely poor compatibility, it claims to have low energy consumption but generates as much heat as a hand warmer, and various other problems, which means that this chip can be said to have reached its peak at its debut and retired at its peak.

It only took a blink of an eye for the whole network to go from praising someone to scolding him.

And now, if the media has obtained information from Huawei, it means that the research on this chip has been almost completed.

The next step is tape-out, testing, and mass production.

Lu Yao thought about it and it seemed like the time was about the same.

The reason for asking the mentor is very simple. The failure of K3V2 made Huawei truly understand what is the right way to go in this field.

That's compatibility.

If it is not compatible, there is nothing to discuss.

That’s why we learned from our mistakes and started the research and development of KIRIN.

Therefore, he wanted to ask his mentor whether the so-called K chip was the K3V2, the K3V2+ that Huawei was determined to develop, or the Kirin that had not yet been officially named.

He certainly couldn't ask before because it was confidential.

But now even the media has got the news, so logically the tutor shouldn't hide it anymore.

It's better to ask clearly.

If KIRIN was just starting out...

Then your stage is too big.

Just as he was thinking about it, Bai Yao's phone rang.

Sun Liqiang has arrived.

So, the two of them waited at the agreed starting point and met their mentor, who was carrying a backpack and holding a laptop, and looked no different from an old programmer.

After the two disciples helped him get his boarding pass, they all went through security and entered the business class lounge. Lu Yao then asked after reading the news on his mobile phone:

"Teacher, let me ask you something."

As he spoke, he handed over the phone.

"?"

Sun Liqiang took the disciple's phone, put on his glasses and looked at it, then flipped to the top of the news again. After seeing the Pacific Center's webpage, he said without waiting for Lu Yao to speak:
"This should be K3V2."

"..."

"..."

After he finished speaking, he saw the puzzled looks of his two disciples.

In other words, Bai Yao was confused, but Lu Yao was speechless.

Is it really that straightforward?
Sun Liqiang thought that the two disciples didn't know what he was talking about, so he said:

“现在和你俩说也没什么，你们别跟别人说就好。这上面的内容，说的是我们上一个研制出的芯片，型号是K3V2是基于K3V1的延伸。K3V1知道是什么吧？”

Bai Yao nodded subconsciously:
"Yes, the one reported earlier this year. But there are no specific parameters."

"Yes, in fact, that chip was successfully developed last year and is considered a test product. Now the progress of K3V2 has also reached the tape-out stage, so it's okay to disclose some information. China has been holding its breath for years, wanting to develop a high-quality and high-performance CPU, and you have seen the performance of this K3V2, quad-core, 64-bit bandwidth DDR memory, 16 GPU units, 1.5GHZ frequency..."

"so tall?"

Bai Yao opened her mouth in surprise.

As a practitioner, she knows very well what the performance of such a CPU represents.

Although not the best, but...

"Purely self-researched?"

"Yeah. Purely self-developed."

After getting the confirmation, a hint of surprise appeared on her face.

But at this moment, Lu Yao suddenly said:
“What is architecture?”

“4×Cortex-A9.”

“Where’s the GPU?”

"Vivante GC4000. Do you know this GPU?"

"Well, Vivante Corporation's GPU uses its own GPU extended multi-core architecture, which has low power consumption and high performance. I have seen their product information on the Internet...but."

Having said this, he paused at a perfect moment.

Sun Liqiang was somewhat pleased with his disciple's knowledge reserve, but he hesitated and asked subconsciously:

"what happened?"

"Teacher... I see they use their own Unified Shader Architecture. The GC2000 they released at the beginning of this year is equivalent to the original version. Although it is not clear how much the 4000 has improved, but... the disadvantages of GC2000 are obvious. They have very poor compatibility with other modes in the GPU. Although they support graphics APIs such as OpenGL ES 2.0, OpenGL ES 1.1 and OpenVG 1.1, in fact, they do very poorly in every graphics API. Not to mention NVIDIA's TEGRA, they are not good at some mainstream APIs on the market. And GC4000 only improves the values. I haven't seen them announce the use of any new technology. If K3V2 is equipped with this GPU architecture... then..."

Under Sun Liqiang's frown, Lu Yao said lightly:
“It feels like this CPU isn’t working well.”
