Chapter 270 No, no, no, no
Sun Liqiang must have participated in the research on K3V2.
Therefore, when the disciple said lightly, "It's not very good", his first reaction was to refute:
"Which aspect is not good?"
He thought he wanted to teach his disciples well.
Although I know that he is excellent and a genius, it is precisely because he is a genius that he should not be arrogant.
All the technologies of this K3V2 can be said to be the most advanced... but they are also the most advanced.
People in the laboratory 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 can't you do this?
But Lu Yao said it became simpler:
"Compatibility. Teacher, the score of GC2000 in foreign tests is so low that it cannot be lower. The GPU architecture he made himself is compatible with many APIs on the surface, but in fact it is like a water gun. No matter how much water is contained in the water gun, the outlet is just a little bit of the gun head. No matter how many things it can be compatible, his processing technology is there, and it is incompatible. For smart phones, it is the biggest defeat, right?"
As he said that, without waiting for Sun Liqiang to answer, he continued with his cell phone:
"Nothing else, you can see..."
He turned on the screen and there was a folder on his mobile phone that contained domestic playback devices such as Youku, Weibo, iQiyi, and even a few mini-games.
"Compared with mobile phones in the 3G era, compared with general users, smart phones are actually not worried about how many parameters you have, how good the performance is. What improves the biggest thing for everyone is its information processing capabilities as a mobile terminal. In the past, I wanted to play games, relax, watch movies, etc., so I wanted to go to the computer to make it. But now mobile phones can meet some of the needs.
And this part of the demand is actually a demand that 80% of mobile phone users will have. They don’t know how to read the running scores, and they don’t care about how high the configuration my phone is... Non-audio users have a very simple understanding of the phone. It can answer calls when it needs to make a call. When the computer is not around, I can also do some entertainment activities with my mobile phone and some information transmission and reception capabilities. In these activities, 80% of the requirements are required, which require the GPU's image processing capabilities to respond.
When GC2000 plays some high-frame videos, the screen is blooming. And I haven't talked about the game yet. Have you seen its review video? Angry Birds is losing frames. It means that its compatibility is so bad that it seems to be fine, it seems to be very high-end, but in fact it is quite ungrounded and is superficial. Did Huawei not realize this? ”
"Of course I took it into consideration. But the performance of GC4000 in this regard is improved in all aspects. They are also changing the problem you mentioned."
"But after all the changes, aren't it just changing the soup or not?... Besides, teacher, haven't you noticed it? Things on mobile platforms are rising rapidly. At this time last year, Angry Birds just came out and became very popular. As a result, look at it now..."
As he said, he opened the best work "The Endless Sword" that can be said to represent the iteration of the mobile game from his mobile phone.
"Look at this picture quality... Jobs won't say it anymore. I can't imagine that this game can actually run on a phone. But look, he was released at this time last year, and the picture quality has been iterated twice in less than a year."
“…”
He was a little confused by the disciple's series of machine guns and cannons, and Sun Liqiang just watched his disciple's HTCSensation.
New this year.
Looking at the knight in armor on the mobile phone, he frowned and asked:
"What is the CPU?"
"Qualcomm S3. GPU is Adreno220. It also supports OpenGLES2.0, OpenVG1.1 and DirectX9.0c. The filling rate is about 88M pixels/sec. The triangle generation rate is about 44M triangles/sec. The 2010 GPU was more than a point ahead of GC200030 in terms of ratings."
"But the fill rate of GC4000..."
"Teacher, didn't we say that VIVANTE has no value, but no compatibility."
“…”
Lu Yao said, turning his head to Bai Yao who was listening to the two of them chatting:
"Notebook."
Bai Yao nodded and immediately took out the notebook from her bag.
Lu Yao put it on his leg, opened it and said:
"I'll show you the detailed evaluation on the oil pipe and you'll know... If you said, 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's brows frowned again:
"Qualcomm and Samsung have begun to develop 28NM. Moreover, the transistor density of 40NM is very low and the energy efficiency ratio is very poor. The chip's operating power consumption will definitely be very high. The power consumption is high, and the heat generation... should not be low, right?"
“…”
Sun Liqiang was speechless.
Because what the disciples are telling the truth.
But they think that the heat generation is not a problem, after all, the performance is here.
After Bai Yao's computer turned on, Lu Yao skillfully turned on the VPN and climbed over the wall. Even the account on the YouTube account is his own.
After opening the collection, he clicked on the media review video and asked him to show it to his instructor, while saying:
"The GPU, GC4000, consumes a lot of power in high load scenarios, resulting in severe heat generation, and is paired with 40NM power consumption... Is there anyone who specializes in this chip to manage and optimize power consumption?"
“…”
Sun Liqiang still didn't say anything.
This is already a confidential work.
Seeing this, Lu Yao thought about it and continued:
"And, mentor, look at my phone. HTC's advertising is thin and thin... And this year, from Samsung, IPHONE, and to other brands, everyone has begun to care about the size of the phone. In other words, thinness is the mainstream trend in the future or in the next few years. Once the phone is thin, its cooling space will be squeezed... Do the K3V2 models have any considerations in this regard?"
“…”
"Also, system scheduling, power consumption management, and temperature control strategies are a complete set of links. If Huawei does not do it well...it seems...it's really not good to use such a GPU architecture. Nowadays, lithium batteries are in high temperature states, and lithium electrons will accelerate movement between the positive and negative electrodes and accelerate chemical reactions. The faster it moves, the lower the internal resistance will be, and the faster the discharge speed will be.
Being in this state for a long time will accelerate the aging of the battery, and it is too troublesome to replace the battery with a smart phone. Everyone is learning from Apple now, so that the battery is embedded. Once the battery ages, people will definitely think it is troublesome to change the battery and leave a bad impression of the brand. These things are chain reactions... and one moves the whole body. Well, to put it this way, my point of view is correct. Although the performance of K3V2 sounds excellent...it doesn't seem to be a successful work. ”
“…”
Sun Liqiang was completely speechless.
He even frowned.
Because... the disciple said it was right.
If it is just a technical aspect, he can argue with his disciples. For example, the VIVANTE architecture he proposed is of no use to evaluate it by his disciples, but its advantages are beyond doubt. The most universal explanation is that it has strong performance and high overclocking.
But from a market perspective... this is not his profession.
Even from the perspective of an ordinary consumer, what the disciple said is right.
These things are indeed a complete set of chain reactions.
It's just as bad, it's really bad.
After all, mobile phones are ultimately something that is the size of a palm. All high-end and high-end products are concentrated in such a large area. Any problem may cause overall problems with the mobile phone.
He frowned and thought.
At the same time, watching the videos in the laptop.
Looking at these media that he was not particularly popular in the past, he tested several GPU architectures through various software to discuss the pros and cons...
What the disciple said is wrong. Although VIVANTEGC4000 is very powerful and is the absolute front-line, its performance is quite poor.
He was only responsible for chip development before, but he was not able to make decisions on the GPU architecture.
It is HiSilicon's comprehensive choice based on authorization fees, costs, etc.
But... at this moment, following the 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 arriving in Shenzhen, I will ask you to learn more about it in the afternoon. If you have any questions, you can directly contact the engineers on their side. Ask all your doubts and get an explanation, when you go back, you can write me a report as soon as possible. You can also write down the things we discussed today and leave them to me."
"Okay."
Lu Yao nodded.
By the way, that's all.
Although K3V2 is not useless... he must express his point of uselessness in himself.
Because...
Have a better and more mature design plan instead.
But Huawei will definitely not adjust its plan just because of one of its own reports... that's unrealistic.
Let’s not mention how much it cost to develop K3V2. Just from the timeline, K3V2 must have begun to be laid out on mobile phones. Once it is stopped, the entire model and 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 itself, Huawei only realized these disadvantages after it was launched on K3V2.
Then start to adjust the strategic focus.
As for consumers, they cannot be said to be cheated.
I can only say that the performance of this CPU is very disappointing, but if it is used on a daily basis, it has a relatively high heat, but it is quite solid and durable in other aspects.
Moreover, this is not their fault. It is really embarrassing that the 45NM node is really embarrassing.
To put it simply, ARM's Mali has not yet become a climate, and Imagination's PowerVR has not authorized the open architecture to the Celestial Empire. This is HiSilicon's second attempt, and it is simply normal for lack of experience. To put it bluntly, this is the constraint of the times and the constraint of technology. The GC4000 GPU is also an absolute draw. Just looking at its value, it's really invincible. But the problem is that once the temperature rises, it will reduce the frequency. Before the frequency is reduced, it is Jordan, but after the frequency is reduced, it will become Chopper directly.
This is its most pitiful point, and it is also the main reason why even VIVANTE's highest-end GPU is still very unpopular worldwide and has a very low licensing fee.
Capitalist societies are all very realistic.
If things are good, they will naturally be expensive.
But the things are not good, even if they look good, they cannot sell at the price, so there must be problems.
HiSilicon is simply being deceived by its own value of "good quality and low price".
There are so many good things and low prices in this world...
Especially in capitalist society.
Really not.
No need to think about it.
At this time, the service staff from the VIP waiting room of the business class came over and reminded him that he could board the plane.
So the three of them stopped talking, after all, this would make people talk too much and it would be inconvenient to chat.
They packed their own things and left together.
Sun Liqiang walked in front and two disciples walked behind.
Bai Yao pulled Lu Yao, leaned into his ear and said:
"You just looked so sexy when you called the tutor."
"..." Lu Yao's mouth twitched.
He looked at the madman speechlessly, looking at her eyes with foggy... He understood very much.
This is the virtue when she is moved.
"Calm down, it's in broad daylight..."
"Well, I'll try my best."
Bai Yao nodded with a smile.
Follow him and continue walking forward.
But... Lu Yao's nose moved slightly.
The sandalwood smell became a little stronger.
...
After arriving in Shenzhen for 2 hours, at the airport exit, the three of them got on an Alpha business car to pick up, and then arrived at the Hilton Hotel Sakata, not far from Huawei's headquarters.
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
Not to mention, Lu Yao was quite unfamiliar with this hotel, because when it was his turn to deal with Huawei in the future, Huawei had already built an Anpu Yiju Hotel specially used for reception, and it was very comfortable to stay in the hotel.
But now, Huawei obviously has no plans yet, but has just arranged it to be the closest place to its headquarters.
HiSilicon's scientific research related is definitely not here. The reason why Sun Liqiang brought the two of them here was to get an access card and fill in the information so that the two of them can come over to deal with these people in the future.
But these things were put into the afternoon.
It was already noon now, and Sun Liqiang took the two disciples to have dinner directly.
I didn't eat the working meal arranged by Huawei, but went to a house where I went according to his own words, which was a pork belly chicken that I had to eat once every time I came.
The pork belly chicken tastes good, and the mentor treats the guests and the two of them have a feast.
After eating, I went back to the hotel to rest.
It's 1:30 this time, and the afternoon service is 2:30.
In just one hour, Bai Yao forced him to ask for him once.
He was speechless, too.
Finally, at 2:30, at the hotel lobby, Sun Liqiang looked at Bai Yao with some confusion, not understanding what bath she took at noon...
Finally, he brought two people into Huawei's headquarters building.
Then a few people came to receive Lu Yao and his senior sister, and took them to fill in the personnel information. In less than ten minutes, the two got the temporary worker card.
With this work card, it means that the two of them can go to and from Huawei headquarters and HiSilicon scientific research department with Sun Liqiang.
Of course, this work card is actually quite difficult to get, and Sun Liqiang must be guaranteed.
This also reflects his trust in the two disciples.
Even in Bai Yao's words, "As far as I know, there are no more than 3 senior brothers and sisters who come to Huawei with their mentors."
After counting the two of them, the number has risen to 5.
After leaving the headquarters, he got on an internal vehicle and the three of them arrived at HiSilicon Semiconductor, which was next to Huawei's headquarters.
This is indeed the first time Bai Yao has come here. She is sitting in the car and looks at this "factory" that is not a particularly conspicuous at present. But Lu Yao has really come here many times in his previous life, and even witnessed the expansion of the base.
Although every grass and tree cannot be said to be familiar with each other, it is not a matter of separation.
So in Sun Liqiang's eyes, this disciple was simply too calm.
"Lu Yao."
"Hey."
"What are you thinking?"
"I wonder how to write that report."
Hearing this, Sun Liqiang nodded:
"Well, don't worry, just give it to me within a month after you go back. Today, you two will come. There will be engineers who will connect with you two. We mainly take you here and recognize the door. Then you will follow the engineers to look around the factory and visit it. Just come and find me after you finish your reading."
He briefly explained his work, and then the car stopped in front of HiSi's administrative building.
As soon as I got off the car, a few men under the steps, who seemed to be in their thirties and forties came over.
There are seven people in total.
One of them shouted:
"Teacher."
Lu Yao and his senior immediately understood the identity of this person.
Sun Liqiang nodded and pointed at them:
"I'll introduce you to Huang Feng, your senior brother. Xiao Feng, this is Lu Yao, this is Bai Yao. Shuang Yao combination."
“…”
“…”
In the speechless eyes of the two, Huang Feng stretched out his hand with a smile:
"Hello, junior brother, junior sister. Who is the older of you?"
"…she."
While shook hands with him, Lu Yao said helplessly:
"Teacher, don't we say I won't use this nickname?"
"Haha."
Amid Sun Liqiang's laughter, the three of them finished greetings.
Then, Huang Feng said:
"Teacher, then I'll ask me to take my junior brother and sister to take a walk first?"
"Yeah."
"Okay, Bai Yao, these two are also engineers in our laboratory. This is Liu Weiqun, and this is Zhang Hai. Xiao Liu, you can take my junior brother and sister to our place."
The two engineers nodded quickly and greeted Lu Yao.
Huang Feng pointed out with his hand:
"Teacher, let's go."
"Yeah."
After watching these people leave, Lu Yao also followed the guidance of the two engineers and headed towards... Well, it should be the optical center, that direction.
He and Bai Yao walked over there.
To be honest, HiSilicon Factory is not uncommon for Lu Yao.
He has seen these places countless times.
But it is obviously quite rare for Bai Yao, and they talk all the way.
After wandering around for about an hour, he saw that these two engineers didn't talk about anything nutritious. They were all formulaic introductions, and he lost interest.
So he took the initiative to finish the visit and headed straight to the office building.
Found the office where Sun Liqiang is located.
He knocked on the door and saw that there were already seven or eight people in the laboratory, including the tutor.
When Sun Liqiang heard the news, he saw the person coming and waved:
"Come on."
While saying that, he handed Lu Yao a piece of information:
"Look at it, you two."
Lu Yao took it and saw that although there was nothing on the information, he saw several values.
FPGA, RF data I\Q link...
This is the standard RF chip data.
He raised his eyebrows and refused to show Bai Yao. Instead, he roughly read the information and said:
"Teacher, do you want me to optimize the algorithm of this LTE baseband RF software?"
“…”
“…?”
"…??????"
For a moment, several people in the research department, including Huang Feng, turned their heads at the same time and their eyes fell on Lu Yao.
“…optimize?”
Sun Liqiang subconsciously said.
Just saw Lu Yao nodding:
"Yes."
He asked with this information:
"Didn't you see any problem with the transmission algorithm of this LTE baseband?"
“…”
“…”
“…”
Now, everyone's eyes fell on him and couldn't move away.
Although it's just a simple question.
But his strange appearance seemed to be talking about it again...
"No, no, no, no? No, no, you really didn't see it, right?"
No, right?
