Chapter 269 This chip is not good
Lu Yao rarely tells his mother what he is doing.
I didn't want to say it before, and I felt it was unnecessary. But now I have to say it.
Because the plan cannot keep up with the changes, he must show his parents what he is doing in some aspects so that he can let them... in the future, because he encounters some situations, etc., you don't have to worry so much.
The simplest explanation is money.
It can only be money.
Otherwise, he and my mother would say, "Mom, I'm doing a top-secret project research now. A spy is contacting me, so be careful with my dad." Ms. Chen probably would have been 180 after he was high in blood pressure.
Therefore, starting with the money is the easiest thing for family members to accept.
But he never had a chance to tell his mother.
And today happened to catch up, so he just told the truth.
Say it out and let my mother accept it slowly.
And Ms. Chen accepts it?
She was a little reluctant.
What... has raised more than 20 million yuan?
Did the thing that a group of people riding electric bikes carry boxes every day was made by their son? ? ?
"You..."
She was a little shocked for a moment. She had many questions, but she couldn't ask and even felt a little dizzy.
Seeing this, Lu Yao didn't urge him, but drove the car to the vegetable market.
Ms. Chen's first sentence appeared:
"Don't get scratched by someone."
"No, this car has car clothes."
Hearing this, Ms. Chen got off the car.
After being held back by her son habitually, she was stunned... After looking up at her son unconsciously, she suddenly felt that most of the thoughts in her heart had disappeared.
"Sister Chen, come and buy vegetables... Oh, isn't this Lu Yao? She looks so handsome!"
She is an old customer, and many people at the stalls here know her.
While saying hello, when I saw Lu Yao, I also smiled enthusiastically.
Lu Yao responded politely.
Ms. Chen also started to buy dishes that she planned to make for her son at noon today.
She originally wanted to fry a loofah, but Lu Yao pointed to the tomato:
"Mom, I want to eat tomato and eggs."
"Don't choose...you don't know how to choose."
Seeing her son pick up a dark red tomato, Ms. Chen snatched it away speechlessly. Just like when she was a child, she put the tomato in place and pulled her son back a little.
It turned out not to pull...
Only then did she realize that the child was no longer the little guy who followed her butt when she was a child.
He glanced at Lu Yao again, with his unique vision that he had learned for twenty years, he selected two freshest tomatoes and handed them to the stall owner.
Then she swept around and asked:
"Can you eat the loofah?"
"I don't want to eat potatoes... put potatoes in the ribs..."
So she picked two more potatoes.
But considering that the two of them were definitely not enough to eat, I asked someone to cut two dollars of winter melon and planned to go home to cook soup.
Finally, I took a handful of green onions and two cucumbers.
After paying the bill, he pulled his son directly to the meat stall.
After buying the four ribs, she bought some junk food speechlessly under Lu Yao's instigation.
It’s the fried chicken fillet on the cold dish stall.
One winter melon soup, one roasted pork ribs, one tomato and egg, and finally add a cool cucumber.
It must be enough for lunch.
Snacks are just fried chicken fillets.
The things in the vegetable market are better than fresh. Carrying a bag of things, the two of them walked out and got into the car again.
Lu Yao turned the car back and saw that his mother didn't say anything, so he took the initiative to ask:
"Mom, what are you thinking?"
"Do you want to buy some more chicken wings? I haven't cooked chicken wings for you for a long time?"
"Um..."
Lu Yao thought for a moment and shook his head:
"Don't eat anymore, 4 dishes are enough...Are you not going to ask about my company?"
"I wanted to ask at first, but then I thought it was unnecessary."
After buying a vegetable, Ms. Chen, whose doubts had dissipated most of her heart, seemed very calm:
"You have grown up, and I don't understand the things you young people are playing now. For example, this phone...and those...those takeaways. Mom is old."
"I'm not... young."
"You're just sweet-mouthed."
Ms. Chen shook her head with a smile, leaned on the comfortable seat of Bentley, looked outside for many years, and seemed to have changed a lot but seemed to be the same street as before, and suddenly said:
"You will be the pillar of your family in the future, do you know?"
"Uh..."
"You can't learn bad things... Even if the company makes money, you can't spend money too much. You have a lot of money to make money in your life. After you make money, you will have nothing to spend. Do you know?"
Listening to his mother's words, Lu Yao thought for a while and smiled:
"I want to tell you more about my company."
But Ms. Chen answered the question irrelevantly:
"What have your sister talked to you?"
"Didn't you just say it?"
"I didn't listen too much just now, what was she going to do?"
So, on the way back, the mother and son's topics were mainly focused on Lu Qing.
After seeing that his son had already started to manage the family, Chen Aihua suddenly felt very relaxed.
It seems that my son grew up overnight, and the feeling of becoming sensible is quite wonderful.
It gave her an illusion that it was not very real.
However, after gradually calming down, she began to care about her son's company.
Lu Yaoxin said that you are really quick to change your mind. You didn’t understand just now. You just started to have dinner and started talking about these things again.
So he explained these things carefully, and after he made Ms. Chen make sure that her experience was useless and she couldn't get into any trouble, she chose to trust her son.
Anyway... my son is very outstanding.
Excellent and sensible.
When it comes to parents in this kind of thing, you only need to be open-minded.
...
Lu Yao stayed at home for two days. Since his mother was transferred to work, she met her son on Saturdays and cooking for him became a regular activity.
And on Sunday night he went to school.
First, the 305 people held a meeting, and then after touching the fish in the laboratory with their senior sister for a day on Monday, on Tuesday, early in the morning, the two arrived at the airport directly.
After the senior sister helped him change the ticket, Lu Yao realized...
"Business Class?"
"Yes."
Bai Yao nodded:
"It seems that Huawei is treated well."
"No, you should say that the tutor is well paid, or very high. After all, from the academic average of semiconductor practitioners, graduate students are not in the first class."
Lu Yao said, feeling a little emotional...
When he was a graduate student in his previous life, his supervisor took them to meetings and so on, and several people were trying hard to squeeze in economy class.
He was really in business class because he started studying for a doctorate and followed his mentor to take charge of the research and development of related chip projects.
But from this point of view, the status of the instructor is obviously much higher in HiSilicon's central laboratory. Of course, then again, in fact, if you can work in the laboratory, your treatment must be superior to that of researchers in other research departments of HiSilicon.
The central laboratory is HiSilicon's most important and top laboratory.
Unfortunately, all the researchers in the laboratory of HiSilicon Center, whether they are formal or supervisors, have their identities confidential. As long as they don’t say it, outsiders don’t know it at all.
When he first went to Shenzhen City with his mentor, he also had economy class.
Tsk tsk...
With a little bit of emotion about the change of things, Bai Yao said:
"I looked at the Pacific website yesterday, and some media have already received some information on it, saying that Huawei is developing a new mobile phone chip and has learned the lessons of K3V1... The performance will be comprehensively improved, which is what Huawei engineers said in an interview. Have you read this article?"
"No." Seeing that Lu Yao hadn't seen it, she thought for a while and asked:
"You said... the Huawei K chip that the instructor mentioned is this new chip?"
"It's hard to say, when did you read this article?"
"Last night. When you were sleeping."
"...You said you were sleepy and asked to turn off the lights, which means I fell asleep and you haven't fallen asleep yet?"
"I can't sleep anymore."
The senior Leng Yan, who was wearing 1.8 meters of shoes and looked very strong, shrugged casually:
"Who told you to let me coax you to bed."
"I mean I'm blamed?"
Lu Yao rolled his eyes and continued to ask:
"Did the article be published yesterday?"
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
"Yes, yesterday afternoon."
"You can ask the tutor at that time."
"...What do I ask? This is confidential."
Seeing that she was so naive, Lu Yao rolled his eyes directly:
"Think about it, since this chip has appeared in the media, and even the media has interviewed Huawei engineers, it means...at least its work difficulties have all ended, and the progress has reached more than 90%. Otherwise, Huawei people would not be able to let go and tell others that they have created a new chip. This kind of R&D is confidential, and without the instruction of the headquarters, who dares to say it? Which media can interview? So, as long as there is news, it means that it must be almost completed, and maybe even the film has been passed."
"So?"
Bai Yao still looked puzzled.
Lu Yao shrugged:
"So, just ask the tutor with that article and ask the media if the article is being studied."
"Well, I still don't understand very much. Otherwise, you'd better ask."
"What's this...huh?"
Suddenly, Lu Yao, who had reacted, suddenly looked at her.
The senior sister still had a cold face.
But Lu Yao understood her micro-expression:
"Take me to push the tank, right? Are you going to be a little more terrible?"
"Those who are capable should work harder."
"I believe you."
While shook his head, he took out his cell phone and handed it to her:
"Find that article."
I really have to ask.
Strictly speaking, K3V1 was actually developed last year, but this year, on the 9th of next month, Huawei will launch its first mobile phone equipped with K3V1, a very low-end and low-end chip, and it is also the first mobile phone of "Huawei Honor".
Like the first mobile phones of all new brands, Honor U8860 equipped with K3V1 is a product for the low-end mobile phone market. In order to seize the market and fight a price war. Secondly... this is HiSilicon's first chip, which is a preliminary attempt in the field of processors.
Not a very successful model.
This also led to Huawei being labeled as "cheap" at that time, so it took several years to clear it up.
I don’t know if it’s not worth the money from a business perspective.
The development of K3V2 was at least May 2012 when Huawei announced it. At that time, Huawei announced some parameters, which is the smallest quad-core A9 architecture processor in the industry, which is a high-performance CPU, which is twice as many as Nvidia's TEGRA3 memory bus, etc.
Good guy... the domestic media was having a carnival.
This processor is a big blow, and in the most fashionable terms, it is really a "catch-up with the advanced level of the world".
As a result, in January 2013, everyone was stunned when the AscendD2 phone was launched.
The VIVANTEGPU architecture with extremely poor compatibility, with low energy consumption but keeping up with the heat generation of the handwarmer treasure, as well as various problems, makes this chip the peak of its debut and retirement at its peak.
It was a blink of an eye to the whole network and scolding it all.
Now, if the media has obtained the news from Huawei, it means that this chip has been researched almost all.
Next is flaking, testing, and mass production.
Lu Yao thought about it and it seemed that time was almost the same.
The reason why I asked the mentor is very simple. The failure of K3V2 made Huawei truly understand what the kingly way is in this field.
That's compatibility.
Incompatible, nothing is discussed.
That's why I learned from my mistakes and started to develop KIRIN.
So, he wanted to ask his mentor whether the so-called K chip is this K3V2, or the K3V2+ that Huawei did not give up, or the Kirin that has not been officially named.
He definitely couldn't ask before, because it was a secret.
But now even the media has received news, and the reasoning tutor should not hide anymore.
It is better to ask clearly.
If KIRIN is just starting...
Then my own stage is too big.
Just as he was thinking, Bai Yao's phone rang.
Sun Liqiang has arrived.
So, at the agreed departure, the two waited to carry a backpack and a laptop in their hands, and seemed to meet with an old coder who was indistinguishable from the tutor.
After the two disciples helped him change the boarding pass, they passed the security check together and entered the business class lounge. After Lu Yao took the news on his mobile phone, he asked:
"Teacher, let me ask you something."
He handed over his cell phone while saying that.
"?"
Sun Liqiang took the disciple's cell phone, put on glasses and looked at it, then turned the news to the top. After seeing the web page of the Pacific Center, Lu Yao said before he could speak:
"This should be K3V2."
“…”
“…”
After saying that, he saw the puzzled gazes of the 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:
"It's nothing to talk to you now, just don't tell others. The content above is about the chip we developed last. The model is K3V2, which is based on the extension of K3V1. Do you know what K3V1 is?"
Bai Yao nodded subconsciously:
"I know, the one reported at the beginning of this year. But there are no specific parameters."
"Yes, in fact, that chip was successfully developed last year, and it was considered a test piece. Now the progress of K3V2 has also reached the tapping stage, so it is nothing to disclose some news. China has been taking a breath over the years to develop a high-quality and high-performance CPU. You have also seen the performance of this K3V2, quad-core, 64bit bandwidth DDR memory, 16 GPU units, 1.5GHZ frequency..."
"So high?"
Bai Yao opened her mouth wide in surprise.
As a practitioner, she knows very well what the performance of such a CPU represents.
Although not the best,...
"Pure self-development?"
"Yeah. It's purely self-developed."
After confirmation, her expression also showed a hint of amazement.
But at this moment, Lu Yao suddenly said:
"What is the architecture?"
“4×Cortex-A9.”
"Where is the GPU?"
"VivanteGC4000. Do you know about this GPU?"
"Well, Vivante Corporation's GPU uses its own GPU to expand multi-core architecture, with low power consumption and high performance. I have seen their product information on the Internet...but."
Speaking of this, he had a just right pause.
Sun Liqiang was still a little pleased with his disciples' knowledge reserves, which showed that he was hesitant and asked subconsciously:
"What's wrong?"
"Teacher... I think they use their own UnifiedShaderArchitecture. The GC2000 they released at the beginning of this year is equivalent to the original version. Although it is not clear how much value the 4000 has been improved, the disadvantages of GC2000 are very obvious. They have very poor compatibility with other modes in the GPU. Although they support graphics APIs such as OpenGLES2.0, OpenGLES1.1 and OpenVG1.1, in fact, they do very poorly for each graphics API. Not to mention that compared with Nvidia's TEGRA, they can't do anything that is mainstream on the market. And what GC4000 has only improved the numerical value, I haven't seen any new technology they announced. If K3V2 is equipped with this GPU architecture... then..."
Under Sun Liqiang's frown, Lu Yao said lightly:
"I feel like this CPU doesn't work."
