Daguo Technology starts with mobile phones

Chapter 36 No one cares
In the next period of time, the members of Nebula Technology's R&D department expanded again, and devoted part of their energy to chip design.

Why part of the energy?

Because when Liu Dalang released the news that Xingyun Technology had broken through the 65~40nm nanoimprint technology, no one cared about it!
It's not that no one came at all. The major mobile phone manufacturers and some colleagues first congratulated, and then... there is no more!

How could this happen?

After finally coming to a few companies, not asking for cooperation, but opening their mouths to buy Nebula Technology, Liu Dalang naturally wouldn't agree and sent off the guests directly.

"Hey! We have broken through NIL technology! We are the second company in China that can produce chips below 100 nanometers!"

What about people?

people! ! !

Just when Liu Dalang was puzzled, he finally discovered a problem. It turned out that the industry did not know enough about nanoimprint technology.

Nebula Technology did not make a big publicity on this technology, and the few manufacturers who came saw it, and it didn't work, and there wasn't even a finished product.

And according to theory, nanoimprinting technology will be better used in flash memory chips, and it is impossible to make real high-precision chips with this technology.

But let's give it a try!

In fact, if you think about it, the supply chains of major manufacturers are also very complete. For flash memory chips, they will not rely on domestic manufacturers.

Nebula Technology itself has not yet produced a finished product, nor has it tested whether nanoimprinting technology can be mass-produced. Doesn't it make it clear that it is going to bring injustice?
No one wants to be the victim of a big injustice, and designing flash memory chips is not what major manufacturers are good at, so it can only attract some chip design companies.

Instead of designing chips by yourself, it is better to buy off-the-shelf, existing products, without investing in R&D and design costs, and with less time and risk.

Faced with this situation, Liu Dalang also had his own solution. On the same day, he publicly stated:
"Ningyun Technology, as long as it doesn't fall, will always be on the road of localization!"

It is a pity that Liu Dalang's remarks did not arouse widespread approval, and were criticized by many people.

Generally speaking, where is the lens so powerful, where is the chip design good, and where is the sensor so good.

In a word: the moon is rounder abroad.

Liu Dalang didn't refute them either, who let himself down, what they said was the truth.

Before Huawei lost power, how many domestic manufacturers paid attention to developing their own technology?

But there is one thing, Huaxia officials will never treat any local scientific research company badly.

Nebula Technology immediately received strong support after contacting the official, because this is not a chip scam, but genuine technology.

Whether it can be used, whether it is easy to use, it is enough to design a chip!

With official support, Nebula Technology needs money, people, and various policies. The conditions are different from the original.

In order to verify whether nanoimprint technology can produce SOC, Nebulas R&D Department set up a chip design project team.

Currently, two chips are being designed, code-named "Chang Gung", one is a 65nm process chip, and the other is a 40nm process chip.

The three chips that Liu Dalang wants most are mobile platform chips, baseband chips, and radio frequency chips.

These three are more important. Other power management chips, switch module chips, battery management chips, etc. are very simple.

Liu Dalang is not sure when the first "Chang Gung" chip will be released, because it is also the first time they have made this kind of chip.

Chips produced by nanoimprint technology have a completely different internal stacking method from conventional chips.

Including the architecture, you have to study by yourself, experiment after experiment, and tape out again and again, it is a bottomless pit, and the final result is still unknown.

In the note7 era, Samsung used Samsung's self-developed architecture for the first time, and then was forced to switch to the public version architecture due to various problems.

The staff of Nebula Technology R&D Department also want to use the public version, come quickly!The problem is that the technology is different, and it will definitely not work if you use the public version!

Fortunately, the technology is already there, and as long as the design is explored a few times, there will always be a solution.

Liu Dalang suddenly missed the "Nine Heavens" series of chip blueprints in the [Technology Collection], but unfortunately the cheapest blueprints are all 7 nanometers.

The 40nm SOC is produced as a pure low-end processor. Lianfa is already 28nm, who still uses 40nm?
Of course, even if the "Chang Gung" chip is successful, only a part of it can be used to make Dalang mobile phones, and the rest of the production capacity is in the hands of the official.

According to Liu Dalang's judgment, in a short period of time, within about a year, it will be difficult for Nebula Technology to use this low-end chip.

Therefore, the R&D department of Nebula Technology only allocates part of its energy. They are not a chip company, and they need R&D in other aspects.

The engineer team led by Lin Dong is the busiest, not only busy with the adaptation of the Nebula OS, but also working part-time on the development of Nebula native APP.

At present, it mainly focuses on Nebula Video, Nebula Reading and Nebula Games, and now it is more like a website navigation that optimizes the user experience.

Move the content from other platforms or webpages directly, remove the advertisements, make the interface simple and rich in functions, and improve the user experience.

Of course, the copyright fees paid for this kind of platform are not low. Lin Dong and others used it as an early choice, and then turned it into their own platform.

Other project teams are also very busy. Sony's two cameras have arrived, and Xingyu-Mu's photography algorithm is still being optimized.

There is also a chip test. This chip test is to test the purchased chip and adjust the screen parameters. After all, the visual perception is the first.

Although the C-level LCD screen is only 720P, it can be fine-tuned to maximize the 720P screen, making the display effect comparable to 1080P.

The current highest priority is still the next-stage product. Liu Dalang is even more entangled with the design of Xinghuo-Chi than Xingyu-Mu.

Because Xingyu-Mu does not need to use any flagship chip, as long as the performance can be used, the camera module can be driven, and the stability and smoothness can be guaranteed.

As for the Xinghuo-Chi, as a gaming phone, its performance must be strong enough. As a 4G mobile phone, it must be guaranteed to play games for at least two years.

The current high-end flagship processor, only the Snapdragon 810 can be selected, but the Snapdragon 810 is a full-fledged fire dragon. The 20nm process can't suppress the A57 core at all, and the Android flagships are all overturned.

Only Meizu chose MediaTek's processor and successfully avoided the "Fire Dragon 810" incident, thus gaining a fairly high market share.

What Liu Dalang is going to install on Xingyu-Mu is the same processor as Meizu MX4, MediaTek MT6595, a true octa-core processor.

The shortcomings of this processor are also obvious. The performance is not strong enough. In every aspect, it is beaten to the ground by Qualcomm's Snapdragon 810.

"Since the heat dissipation of the Snapdragon 810 is serious, then this time the Xinghuo-Chi, simply don't add other configurations, just stack heat dissipation and appearance design!"

What is the strongest heat sink?
Passive heat dissipation such as VC vapor chamber, heat dissipation gel, heat dissipation silicone grease, copper foil, etc. will definitely not be able to suppress the Snapdragon 810, so only active heat dissipation is available!
Liu Dalang approached Qu Xiangqun, head of Nebulas Technology Design Department who was thinking hard, and said:

"Redesign it, fill up our Starfire-Blazing Cooler, and add a fan!"

Qu Xiangqun's eyes widened suddenly, and he looked at Liu Dalang, as if he saw Party A's father pointing Jiangshan and berating Fang Qiu!
"Installing a fan in the phone? Redesigning the motherboard and appearance!? I often feel frustrated because I can't keep up with the chairman's thinking!"

There is no way, Party A... No, the chairman is the biggest, so Qu Xiangqun could only listen to Liu Dalang's thoughts with a bitter face, but when he listened...

!!!

Can a mobile phone be designed like this?

"Chairman, but in this way, the weight of the mobile phone is more than 200 grams. If it is used as an ordinary mobile phone, it is a bit..."

Before Qu Xiangqun finished speaking, he realized the problem. Since he chose the game phone path, it is better to make the ultimate game phone!
For daily use, there is also the Xingyu series of mobile phones. Xingyu-Mu invested even more than the Xinghuo-Chi game phone.

The active noise reduction of calls, the improvement of the sound quality of external speakers, the photography algorithm, the appearance design, the back cover technology, etc., are all stronger than Xinghuo-chi.

In terms of screen size, the size of Xingyu-Mu is only 5.5 inches, and Liu Dalang plans to adopt a classic full-screen design on the front: notch screen.

After conveying the idea to the design department, the next important problem is that the material of the C-level LCD screen is very hard.

Unlike OLED flexible screens, which can be bent to make the material hard, the four sides of the LCD screen cannot be controlled, which greatly affects the appearance.

(There is something out of the situation, and I will make it up tomorrow!)
