Rebirth: I carry a desktop computer inside me

Jiang Cheng was a little stunned, he remembered the life path of Qin Jin in the previous life.

Enter the factory and work.

Messed with a girl and gave birth to a child in less than two years.

At this point in time, it is only a year and a half.

I don't know how he got into the brain in this life, and it was also at this point in time that he was involved with Zhang Luochen.

"Mirror, you honestly, what the hell is going on with you?" Jiang Cheng asked with a serious face.

Qin Jin covered his face with his hands, and everyone was still confused, "I don't know what's going on, I played games late that night, and then I went to the barbecue to drink, and then I couldn't go back to the dormitory, so I went to the hotel..." "

I didn't know this kind of thing would happen, I..." Qin Jin's eyes were red, but not crying, but regretful.

Yu Xinran was a little silent.

She couldn't accept this kind of thing.

Because neither of them is sure if it's a boyfriend and girlfriend relationship, just playing around like this happened.

Jiang Cheng said speechlessly, "Didn't you buy Yu Ting later?"

Qin Jin shook his head, "I don't know. I didn't expect this either.

Yu Xinran sighed, "I'll go comfort her." Then

, he looked at Jiang Cheng.

Jiang Cheng patted her hand, "Go." Leaving

Jiang Cheng and Qin Jin sitting opposite each other, the air was a little silent.

"Things have already happened, so stop thinking about regretting things. Think about what to do now, and discuss with Zhang Luochen whether you want to have children, if you don't want to do a flow earlier, if you want, you will do your duty. Jiang Cheng said calmly.

Qin Jin closed his eyes, "Orange, do you think I'm useless?"

"If you believe me, you should listen to me, don't get distracted from side to side during college, and learn to program well." Jiang Cheng shook his head, "But you have to put your mind on her side and help her write books, why are you still crazy and playing around!"

"Do you really like her?"

"I don't know, I should have a like." Qin Jin sighed.

"Okay, let's buy a plane ticket and go over there." Discuss it and make your own decisions. Jiang Cheng stretched out his hand and waved, signaling him to leave.

"Good." Qin Jinchang took a breath, nodded, and left directly.

After waiting for a while, Yu Xinran returned, "What about Qin Jin?" "

Went to buy a ticket." Jiang Cheng shook his head and sighed, "This kid is really like a child. Not big.

Yu Xinran sat down, "Luo Chen is in a very bad mood, he has been crying, he doesn't care every day when it doesn't happen, it doesn't matter, it's really coming, but he can't accept it."

"So, they're all kids who haven't grown up." Jiang Cheng smiled bitterly.

It seems that the sky is not afraid, the earth is not afraid, but if you do not care, how can you not be afraid?

Qin Jin was on a plane to Changshan City, Shonan Province at night.

Jiang Cheng and the two flew to Kyoto the next morning.

His time in Guanglin is getting shorter and shorter, and although Jiang Yiping and Chen Ru are thinking about their son for a few more days, Jiang Cheng has too many things now.

Before leaving, Yu Xuemin also came to send her daughter.

"Xiaojiang, I am relieved to hand it over to you, you must not let her suffer any grievances, got it?"

"I understand."

And Jiang Cheng looked at Jiang Yiping, whose hair began to turn white, and said, "Decorate the store over there this year, set up a small supermarket, the lotus seed business is too tired, don't charge so much."

"Good." Jiang Yiping nodded, his tone still calm.

Just watching the shuttle drive out of the station, the big man's eyes accidentally got into the sand.

When the child grows up, the place he is going is big and far away.

---- δຶᴖ δຶ-----

When they arrived in Kyoto, the two first returned to Manyanagi's house.

Yu Xinran continued to prepare IELTS, and Jiang Cheng also devoted himself to research.

The power management (fast charging) chip is already one step ahead, and Jiang Cheng will continue to research and improve by the company's developers.

According to theory, the charging interface protocol standard designed by Jiang Cheng can reach the limit charging speed of 100W.

Of course, this requires a combination of materials and design.

On this basis, Jiang Cheng focused his research on baseband chips and RF chips.

As for the declared project, Jiang Cheng has already come up with a preliminary algorithm, which is nothing more than a long time of training and experimentation.

This has Wang Sichen and Hao Yongjun busy, he just stares.

What's more, this has just finished the New Year, and it is not so soon to start again.

Nowadays, Jiang Cheng is extensively learning about baseband chips and RF chips.

In mobile terminals, in addition to CPU processors, RF chips and baseband chips are the most important. RF chip is responsible for RF transceiving, frequency synthesis, and power amplification; The baseband chip is responsible for signal processing and protocol processing.

After all, a mobile phone, no matter how many fancy features, calling and messaging, comes first.

Jiang Cheng has the impression that although the fruit machine is good, the signal has always been criticized.

Because often in the same place, Warwick's signal is better than that of fruit.

This experience is generally difficult to feel, but it is especially important when there is no signal or a very weak signal, and you can't hear what the other party is saying for half a day.

The development of baseband chips reflects the continuous innovation of communication technology.

From Motorola's 1G in 1986 to the 2G era, from analog modulation to digital modulation, and from which GSM and CDMA were separated.

In China, the familiar difference between mobile and Unicom is also different from these two network standards.

In May 2000, the third-generation mobile communication standard (3G) was officially released, and the biggest difference is that pictures, video, and audio can be transmitted.

Hua Guo has become one of the standard setters with TD-SCDMA technology in 3G technology.

Around 2011, the 4G standard was officially announced.

Hua Guo has been laying out since 2012, and Jiang Cheng knows that in December 13, 4G licenses will be officially issued, when mobile Internet technology will face takeoff.

At the critical moment, Jiang Cheng could not wither.

He must firmly grasp the core technology to lead the development of science and technology.

What's the point of just making an assembly plant?

The moment the sanctions arrive, it can only be a lamb to be slaughtered!

But baseband chips, as a component of the core, are not so easy to develop.

A baseband chip basically contains 5 modules.

Baseband CPU processors, channel encoders, digital signal processors, modems, and interface modules.

Take a simple example.

We took a Warwick Mate1 and dialed Jiang Cheng's number: 131XXXXXXXX.

When we call, we speak.

The sound is transmitted through MIC (microphone), through AD signal acquisition and voice processing, and then through channel coding, digital signal processor coding into voice coding, and then through the RF module, RF transmission and reception.

In other words, all sounds, in the final analysis, are just digital-to-analog conversions.

Now, Jiang Cheng has just picked up the baseband and RF related books and papers, ready to start reading and studying.

What awaits him is a new path of science and technology.
