Rebirth: I carry a desktop computer inside me

The news that Meizhu executives jumped to Maple Fire has only been lively on the Internet for a few days.

It's just that a few manufacturers in the mobile phone industry are more concerned, because for them, there is one more competitor.

In addition, there are those suppliers of the upstream industry chain, and they are the choice of one more supply object.

Even Yu Shengdong called to congratulate Jiang Cheng on entering the Chinese mobile phone market.

He has long been prepared for this.

People research fast charging, and it is a radio frequency chip, naturally will not let go of mobile products such as mobile phones.

After all, although upstream suppliers also make money, they are not as profitable as mobile phones.

“...... By the way, Mr. Jiang, does your company do baseband chip research? After congratulations, Yu Shengdong asked about it again.

He does not need RF chips, Hisilk has also worked hard for many years in chip design, and the communication equipment is also the boss, and the RF problem is not big.

Jiang Cheng said smugly, "Of course, the current research is very smooth.

"The issuance of 4G licenses is imminent, but I don't know what network standards my brother's baseband chip supports?" Yu Shengdong asked again.

"All Netcom, of course."

Yu Shengdong smiled heartily, "It's a pity, we Haisi have research on these types of chips, so we can't cooperate with your company!"

"If this cooperation fails, there will always be opportunities for cooperation." Jiang Cheng didn't care.

He knows that although Warwick developed the baseband of 5G in the previous life and integrated it into the SOC chip, it is a pity that because of the RF device and the filter, it cannot normally transmit and receive 5G signals.

It is equivalent to sanctions after the use of force.

However, as early as this time, Jiang Cheng had already laid out and tried to bypass existing patents for RF chips such as filters, and made some progress.

At least, Jiang Cheng believes that future 5G sanctions cannot affect him.

After hanging up the phone, Jiang Cheng continued to lead the team to develop baseband chips.

Every day, Jiang Chengdu and the team concentrate their wisdom, discuss various methods and directions for improvement or new expansion, and arrange personnel to make preliminary calculations.

Of course, more importantly, Jiang Cheng will use the internal computer to mobilize no more than 20% of the computing power to conduct simulation experiments.

Under the blessing of small supercomputing, the simulation laboratory in the internal computer is more luxurious, and all kinds of instruments should be available.

It's almost a lithography machine.

In addition to everyone's new design ideas, Jiang Cheng himself is constantly conducting optimization tests in the internal computer.

With the existence of the simulation laboratory, Jiang Cheng was a lot more relaxed.

Others develop chips, which require theoretical design and design verification, and later tape-out testing.

But now, in the simulation laboratory, Jiang Cheng can modify the underlying circuits of the chips and various components that have been simulated at will.

Design verification is then carried out.

The tape-out link is directly saved.

The speed and effectiveness have improved a lot.

By the end of September, Jiang Cheng had tested one design scheme and handed it over to the R&D team for revision and improvement, and if there was no problem with the design verification, it would be ready to tape out again.

Of course, Jiang Cheng believes that everything will go smoothly.

Because these designs have been simulated and tested many times in Jiang Cheng's body.

The remaining core technology is only the mobile phone CPU processor.

As early as the beginning of the year, Jiang Chengcheng asked assistant Lin Feng to lead the formation of a research and development team for mobile phone processors.

Up to now, more than 10 people have been recruited.

Jiang Cheng expects to pay more than 10 million yuan a year to his own employees.

Make money!

If you don't make money, Jiang Cheng, a semiconductor company, will collapse!

After the development of RF chips, it was not the same as Jiang Cheng imagined.

At present, everyone is still only a 3G mobile phone, and they don't use Jiangcheng's 4G full Netcom RF chip, so that a few months after the announcement, no manufacturers have come to talk about RF chip cooperation.

The only Meizhu asked once, but soon the two became mortal enemies, and it was naturally impossible to purchase the chip of Maple Fire.

Of course, it is not Jiang Cheng's research and development mistake, but he is slightly ahead, and the 4G license has not yet been issued!

But it is precisely because of this that Jiang Cheng made up his mind, if you don't purchase, I can use it myself.

Mobile phones are also a profitable industry!

Only by making money can I drive the research and development of various upstream chips to move forward.

"Lin Feng, how is the progress so far?" Entering the Fenghuo mobile phone SOC chip research and development laboratory with strict secrecy, Jiang Cheng looked at Lin Feng.

This originally handsome young man, in half a year, has been a little sloppy.

He was full of enthusiasm and devoted himself to chip research and development.

"Mr. Jiang, according to your requirements, we have conducted in-depth research on the RISC-V instruction set, and I feel that this instruction set does have its advantages, the instructions are fast, the power consumption is relatively low, and it can be used for mobile terminals." Lin Feng's eyes were still very bright.

He still didn't understand Jiang Cheng's choice of ARM architecture at first, but as time went on and after in-depth research with the research team, his view was changing.

For Jiang Cheng, his thinking is more long-term.

The first article is that the ARM architecture licensing fee is very expensive, and you have to pay a huge license fee every year, and it is easy to be stuck.

Secondly, in China, there is already Warwick's Haisi specializing in self-developed chips on the ARM architecture, and Jiang Cheng remembers that the Kirin chip is still very capable of fighting.

In this way, through the ARM architecture self-research, the formation of repeated and invalid competition is what Jiang Cheng does not want to see.

But on the contrary, the RISC-V instruction set, which Jiang Cheng accidentally paid attention to in his previous life, is said to be better supported by artificial intelligence (AI).

The key is that the instruction set is open source and free, allowing Jiang Cheng to develop processor cores based on this instruction set.

Of course, this road is not easy.

"Okay, now that the baseband chip has basically completed the research and development, I will take the time to come over, but we must be prepared for a long-term and protracted battle, strive to produce the first generation of the core next year, design the first generation of SOC chip the year after that, and continue to improve and improve." Jiang Cheng nodded and reminded.

Lin Feng was very happy, "Mr. Jiang, it is best that you will come and take us to research and development, I can hear from several other IC R & D team people, your level is super high."

Jiang Cheng waved his hand, "I'm not an immortal, I can't rely on me for everything, the key is to rely on everyone's concerted research and development."

Under the leadership of Lin Feng, Jiang Cheng learned about the progress of research and development in detail.

Of course, he also put forward his own ideas for the design of the kernel architecture based on the RISC-V instruction set.

Similar to today's mainstream design, the first-generation core Jiangcheng plans to use a large and small core design, 2 large cores, with 2 small cores.

In addition to the design of the CPU, it is also necessary to integrate the GPU, which is still the difficulty of research and development.

If there is no good GPU design, the game screen will drop frames and freeze, which will greatly affect mobile phone sales.

Jiang Cheng hopes most that next year's release of the Maple Fire mobile phone will be able to use its own processor chips.

But time is too tight to be realistic.

He has to think about buying chips first, but whose chips to use?
