Rebirth 2010, the best

Chapter 270 No way, no way

Chapter 270 No way, no way
Sun Liqiang must have participated in the research of K3V2.

So, when the disciple said lightly, "Not so good," his first reaction was to refute:

"What's wrong?"

He thought to himself that he had to give his disciples a good lesson.

Although we know that he is very outstanding and a genius, he should not be arrogant because he is a genius.

All the technologies of this K3V2 can be said to be the most advanced at the moment... not the most advanced, but definitely the best.

People in the lab have great ambitions for this chip. It has the absolute advantages of "small area, 16-core GPU, fast response, and strong information processing", and everyone is full of confidence in it.

Why doesn't it work for you?
But Lu Yao said it more simply:
"Compatibility. Teacher, the scores of GC2000 in foreign tests are already as low as they can be. The GPU architecture developed by VIVANTE is technically compatible with many APIs on the surface, but in fact it is like a water gun. No matter how much water is in the gun, the outlet is only a small amount at the gun tip. No matter how many things it can be compatible with, its processing technology is there. Incompatibility is the biggest failure for smart phones, isn't it?"

As he said this, he didn't wait for Sun Liqiang to answer, and continued with his mobile phone:
"Let's not talk about anything else. Look..."

He turned on the screen. There was a special folder on his phone that contained domestic playback devices such as Youku, Weibo, iQiyi, and even a few small games.

"Compared to mobile phones in the 3G era, for general users, people don't really care about the specifications or performance of smart phones. The biggest improvement is its information processing capability as a mobile terminal. In the past, if I wanted to play games, relax, or watch movies, I had to go to the computer. But now mobile phones can meet some of these needs.

This part of demand is actually what 80% of mobile phone users will have. They don't look at the running score, and they don't care how high the configuration of my mobile phone is... Non-enthusiast users have a very simple understanding of mobile phones. It can make and receive calls when I need to, and when the computer is not around, I can use the phone to do some entertainment activities, as well as some information sending and receiving processing capabilities. And in these activities, 80% of the demand requires the GPU's image processing capabilities to respond.

When the GC2000 plays some high-frame-rate videos, the screen is full of flowers. And I haven't even talked about games. Have you seen its review video? It even drops frames in "Angry Birds". This shows that its compatibility is terrible. It seems to be able to do everything and seems to be very high-end, but it is actually quite unrealistic and superficial. Doesn't Huawei realize this?"

"Of course we have taken that into consideration. But the performance of GC4000 in this regard has been improved in all aspects. They are also correcting the problem you mentioned."

"But isn't it just a matter of changing the soup and the substance? ... Besides, teacher, haven't you noticed that things on mobile platforms are rising rapidly now? This time last year, Angry Birds had just been released and was extremely popular. But look at it now..."

As he spoke, he opened "Infinity Blade", which can be said to be the best work representing the iteration of mobile games, on his mobile phone.

"Look at the quality... Didn't Steve Jobs say that it was unimaginable that this game could run on a mobile phone? But look, it was also released at this time last year, and in less than a year, the quality has been upgraded twice."

"..."

A little confused by his disciple's series of machine-gun talk, Sun Liqiang just looked at his disciple on his HTC Sensation.

This year's new model.

Looking at the armored knight slashing the monster smoothly on the phone screen, he frowned and asked:

“What is a CPU?”

"Qualcomm S3. The GPU is Adreno 220. It also supports OpenGL ES 2.0, OpenVG 1.1, and DirectX 9.0c. The fill rate is about 88M pixels/second. The triangle generation rate is about 44M triangles/second. This 2010 GPU is more than 200030 points ahead of the GC in the score."

"But the fill rate of GC4000..."

"Teacher, didn't we say that VIVANTE has numerical values but no compatibility?"

"..."

Lu Yao said, turning to Bai Yao who was listening to the two people's conversation and said:

"notebook."

Bai Yao nodded and immediately took out a notebook from her bag.

Lu Yao put it on his lap, opened it and said:
"I'll show you a detailed review on YouTube and you'll know... If what you said is true, the K3V2 may have strong performance, but if the GPU is VIVANTE, then... I'm skeptical about the performance of this U. And... what size is it?"

"40NM."

"...40NM, 4-core CA9 architecture?"

Lu Yao frowned again:

"Qualcomm and Samsung have already started developing 28NM. And the transistor density of 40NM is very low, and the energy efficiency ratio is very poor. The power consumption of the chip will definitely be very high. The power consumption is high, and the heat generated... should not be low, right?"

"..."

Sun Liqiang was speechless.

Because the disciple was telling the truth.

But they think heat generation is not a problem, after all, the performance is there.

After Bai Yao's computer was turned on, Lu Yao skillfully opened the VPN and climbed over the firewall. Even the account on YouTube was his own.

After opening the collection, he clicked on the media review video and showed it to his mentor, saying:
"The GC4000 GPU consumes a lot of power under high load, causing severe heat generation. With a power consumption of 40NM... Is there anyone dedicated to power consumption management and optimization for this chip?"

"..."

Sun Liqiang still didn't say anything.

This is already confidential.

Seeing this, Lu Yao thought for a moment and continued:
"Also, tutor, look at my phone. HTC's advertisements promote it as thin and light... and this year, from Samsung to iPhone to some other brands, everyone has started to care about the size of their phones. In other words, thinness will be the mainstream trend in the future or in the next few years. Once a phone is made thin, its heat dissipation space will be greatly squeezed... Has the K3V2 model taken this into consideration?"

"..."

"Also, system scheduling, power consumption management, and temperature control strategies are a whole set of links. If Huawei doesn't do it well... and then uses such a GPU architecture, it seems... it really won't work. When lithium batteries are at high temperatures, lithium electrons will move faster between the positive and negative electrodes, accelerating chemical reactions. The faster it moves, the lower the internal resistance will be, and the faster the discharge speed will be.

If the battery is kept in this state for a long time, it will accelerate the aging of the battery. It is very troublesome to replace the battery of a smartphone. Now everyone is imitating Apple and embedding the battery. Once the battery ages, some people will definitely think that it is troublesome to replace the battery, and then leave a bad impression on the brand. These things are chain reactions... one move affects the whole body. Well, if you put it this way, my point of view is correct. Although the performance of K3V2 sounds excellent... it does not seem to be a successful product. "

"..."

Sun Liqiang was completely speechless.

He even frowned.

Because...what the disciple said is very true.

If it was just about technology, he could argue with his disciples, for example, the VIVANTE architecture he proposed, although it was criticized by his disciples as having no merit, its advantages are unquestionable. The most universal explanation is that it has strong performance and high overclocking.

But from a market perspective...that's not his expertise.

In fact, from the perspective of an ordinary consumer, what the disciple said is correct.

These things are really a complete chain reaction.

If one thing is bad, then everything is bad.

After all, a mobile phone is ultimately a palm-sized device, with all the high-tech features concentrated in such a small area. Any problem may cause overall problems with the phone.

He frowned, thinking.

At the same time, I was watching the video on my laptop.

He watched these media, which he had never thought highly of before, testing several GPU architectures through various software and discussing their pros and cons...

What I said is absolutely correct. Although VIVANTE GC4000 has strong performance and is absolutely first-class, its expressiveness is quite poor.

He was only responsible for chip development before, but he was not in charge of making decisions on GPU architecture.

It is HiSilicon’s own choice based on licensing fees, costs, etc.

But... at this moment, following his disciple's thoughts, he suddenly discovered that there seemed to be a big problem here.

After watching the video bit by bit, he thought for a while and said:
"After we get to Shenzhen, I'll have someone take you through the details this afternoon. If you have any questions, you can talk to their engineers directly. Ask all your questions, and after you get an explanation, go back and write me a report as soon as possible. Include the things we discussed today, and give it to me."

"it is good."

Lu Yao nodded.

That’s all I have to say.

Although K3V2 is not completely useless... he must express the point of view that he is useless.

because……

I have a better and more mature design solution to replace it.

But Huawei will certainly not adjust its plans just because of a report of its own...that's unrealistic.

Regardless of how much money was spent on the development of K3V2, just from the timeline, K3V2 must have been deployed on mobile phones. Once it is stopped, the entire model, or even the entire mobile phone series, will be stopped. This kind of loss is something that no company will bear.

What's more, if it weren't for me, Huawei would have realized these drawbacks only after K3V2 was launched on the market.

Then start adjusting the strategic focus.

Consumers cannot be said to have been cheated.

I can only say that the performance of this CPU is disappointing, but if it is used in daily life, except for the higher heat generation, its performance in other aspects is quite solid and durable.

Moreover, it is not their fault, the 45NM node is really awkward.

In a small sense, ARM's Mali is not yet established, and Imagination's PowerVR has not yet opened its architecture license to China. This is HiSilicon's second attempt, and it is normal that they lack experience. In a big sense, this is the constraint of the times and technology. The GC4000 GPU is also an absolute pie in the sky. If you just look at its numerical value, it is really invincible. But the problem is that once the temperature rises, it will reduce the frequency. Before the frequency reduction, it is Jordan, and after the frequency reduction, it directly becomes Chopper.

This is the worst part about it, and the main reason why even though it is VIVANTE's most advanced GPU, it is still unpopular worldwide and has a very low licensing fee.

Capitalist societies are very realistic.

If something is good, it will naturally be expensive.

If something is not good, even if it looks good, but cannot be sold at a high price, there must be something wrong with it.

HiSilicon was simply cheated by its own value of "high quality and low price".

There are so many cheap and good things in this world...

Especially in capitalist society.

Really do not have.

No need to think about it.

At this time, the service staff of the business class VIP lounge came over and reminded us that we could board the plane.

So, the three of them stopped talking. After all, it would make people gossip and make chatting inconvenient.

They packed up their things and left together.

Sun Liqiang walked in front and his two disciples followed behind.

Bai Yao pulled Lu Yao and whispered in his ear:

"The way you were talking to the instructor just now... was so sexy."

“…” Lu Yao’s mouth twitched.

He looked at this crazy woman in silence, looking at her misty eyes... He understood it too well.

That's how she behaves when she's in love.

"Calm down, it's broad daylight..."

"Yeah, I'll try my best."

Bai Yao nodded with a smile.

Follow him and continue forward.

But... Lu Yao's nose twitched slightly.

The scent of sandalwood became a little stronger.

……

Two hours after arriving in Shenzhen, the three of them got on an Alpha business car at the airport exit and then went to the Bantian Hilton Hotel, not far from Huawei's headquarters.

It’s no wonder that Lu Yao was quite unfamiliar with this hotel, because when it was his turn to deal with Huawei in later generations, Huawei had already built an Anpu Yiju Hotel specifically for reception, and that hotel was very comfortable to stay in.

But now, Huawei obviously has no such plan and has only arranged it to be in the place closest to its headquarters.

HiSilicon's scientific research is definitely not here. The reason why Sun Liqiang brought two people here was to apply for an access card and fill in some information to make it convenient for the two to come here and deal with these people in the future.

But all these things were put off to the afternoon.

It was already noon, and Sun Liqiang took his two disciples to eat.

He did not eat the work meal arranged by Huawei, but went to a pig stomach and chicken restaurant, which he said he must eat every time he comes.

The pork belly and chicken tasted good. The instructor treated us and we both ate with relish.

After eating, I went straight back to the hotel to rest.

It's 1:2 now, and we'll gather at : for this afternoon's work.

In just one hour, Bai Yao forced herself on him once more.

He was also speechless.

Finally, at 2:, in the hotel lobby, Sun Liqiang looked at Bai Yao in confusion, not understanding why she was taking a bath at noon...

Finally, he took the two of them into Huawei's headquarters building.

Then a few people came to receive Lu Yao and the senior student, and took them to fill out some personnel information. Then in less than ten minutes, the two received temporary worker cards.

With this work card, the two of them can follow Sun Liqiang to enter and exit Huawei headquarters and HiSilicon's research department.

Of course, this work card is actually quite difficult to get, and you must have Sun Liqiang as a guarantor.

This also reflects the degree of trust he has in his two disciples.

Even in Bai Yao's words, "As far as I know, there are no more than three seniors who followed their mentor to Huawei."

After counting the two of them, the number has barely risen to 5.

After leaving the headquarters, they got directly into an internal vehicle and the three of them came to HiSilicon Semiconductor, which is right next to Huawei's headquarters.

Bai Yao was indeed here for the first time, and she looked curiously at this "factory" which was not particularly conspicuous at present. But Lu Yao had come here many times in his previous life, and even witnessed the expansion of the base.

Although I cannot say that I am familiar with every blade of grass and every tree, I am not unfamiliar with them either.

So in Sun Liqiang's eyes, this disciple was simply too calm.

"Lu Yao."

"Eh."

"What are you thinking about?"

"Think about how to write the report."

Hearing this, Sun Liqiang nodded:
"Well, there's no rush. Just give it to me within a month after you go back. I'll let you two come today. An engineer will be meeting with you in a while. He'll mainly take you around here and let you get acquainted with the factory. You'll follow the engineer to look around the factory and have a tour. When you're done, come find me."

He briefly explained the work, and then the car stopped in front of HiSilicon's administrative building.

As soon as I got off the car, several men who looked to be in their thirties or forties came over from the stairs.

Seven people in total.

One of them shouted:
"teacher."

Lu Yao and his senior immediately understood this person's identity.

Sun Liqiang also nodded and pointed at the two of them:

"Let me introduce you to Huang Feng, your senior brother. Xiao Feng, this is Lu Yao, and this is Bai Yao. The Double Yao combination."

"..."

In the speechless gaze of the two people, Huang Feng smiled and stretched out his hand:

"Hello, Junior Brother and Junior Sister. Who is older between you two?"

"……she."

Lu Yao shook hands with him and said with some helplessness:
"Teacher, didn't we agree not to use this nickname anymore?"

"Haha."

Amid Sun Liqiang's laughter, the three of them finished greeting each other.

Then, Huang Feng said:
"Teacher, should I ask someone to take the junior brothers and sisters around first?"

"Ah."

"Okay, Bai Yao, these two are also engineers from our laboratory. This is Liu Weiqun, and this is Zhang Hai. Xiao Liu, you can show my junior brothers and sisters around here."

The two engineers nodded quickly and greeted Lu Yao and the others.

Huang Feng raised his hand and said:
"Teacher, let's go."

"Ah."

After watching these people leave, Lu Yao followed the guidance of the two engineers and headed towards... well, it should be the optical center, that direction.

He and Bai Yao walked towards that direction together.

To be honest, the HiSilicon factory is not new to Lu Yao.

He had seen these places countless times.

But it was obviously quite rare for Bai Yao, and she kept chatting and walking along the way.

After walking around for about an hour, he lost interest when he saw that the two engineers didn't talk about anything meaningful and were just giving some formulaic introductions.

So I took the initiative to end the tour and went straight to the office building.

Found Sun Liqiang’s office.

He knocked on the door and saw that there were already seven or eight people in the laboratory, including his supervisor.

When Sun Liqiang heard the noise and saw the person coming, he waved:

"Come."

As he spoke, he handed Lu Yao a document:
"You two take a look."

Lu Yao took it and looked at it. Although there was not much content on the information, he saw a few numbers.

FPGA, RF data I\Q link...

This is standard RF chip data.

He raised his eyebrows and did not show it to Bai Yao. Instead, he glanced at the information and said:
"Instructor, do you want me to optimize the algorithm of this LTE baseband RF software?"

"..."

"...?"

"...????"

At that moment, several people in the laboratory, including Huang Feng, turned their heads at the same time and their eyes fell on Lu Yao.

"……optimization?"

Sun Liqiang said subconsciously.

Lu Yao nodded:
"correct."

He took the document and asked:

"Don't you see that there is something wrong with the transmission algorithm of this LTE baseband?"

"..."

Now, everyone's eyes were on him and couldn't be moved away.

Even though it was just a simple question.
