At the end of the meeting, everyone also went to prepare, the environment should be built, and the code should be read.

Nie Zhenyuan found Ma Tian who left: "Mr. Ma, wait a minute, there are still some things that we may not have made clear." ”

Ma Tian stopped, looked at Nie Zhenyuan, frowned, and said, "Is there anything else I didn't make clear at the meeting?" ”

"It's not this, it's already clear that you're going to plan for the technical side, it's about the two companies that settle the compensation." Speaking of this, Nie Zhenyuan was also a little embarrassed.

Zheng Shi saw that their engineers were fine, how to calculate the remuneration of Ma Tian, the chief engineer?

It is estimated that Ma Tian can't look down on it for hundreds of millions.

There is also the cost of voice assistants, and the voice assistants are not patented, so I don't know how to calculate them.

But it is impossible not to pay Ma Tian, and I dare not give it if I can't say it.

Ma Tian laughed when he heard this, this matter is indeed not easy for him to handle from Xia Wei's point of view.

"The remuneration of the two companies should go according to the normal process, it should be Tianyu's patent is Tianyu's patent, you can give as much as you want, except that I am a free helper.

But I hope you will keep in mind that this time I will stand up the backbone of the high-end domestic mobile phone market and hit Pingguo's arrogance on our side! ”

Ma Tian's tone became more and more serious, and Nie Zhenyuan also heard that what Ma Tian said was not a lie, and he immediately became in awe.

"Mr. Ma, you can rest assured that the high-end market of domestic mobile phones will not be occupied by foreign countries, and we will always be at the forefront."

Ma Tian nodded, left a sentence of "good", and went back to his office to read the code, as the chief engineer, he must understand everything, and Xia Wei's source code must also carefully look at the architecture to coordinate the overall situation.

In the three-step plan, chip design is the top priority, but also the most difficult.

Because the chip design is very complex, the complexity of the internal circuit units of a chip can reach tens of billions, and those who have been in contact with the chip field know its difficulty.

This time, even if it is not a main CPU chip, but just a module chip, Ma Tian expects that the circuit units will reach several million.

Chip design is roughly simplified in layman's language into three steps:

The first step is to identify the functional requirements, including the size and power consumption of the chip, and what it is intended for.

A mobile phone is so big in the palm that you must consider where the chip is placed in the right position, and it cannot have a large power consumption, because you have to consider the standby power and safety certification.

Ma Tian wants to design a voice recognition assistant this time, and its function is naturally to convert voice signals into digital signals, that is, 0 and 1 that machines can recognize.

The second step is to use verilog or VHDL hardware description language to write the required functions, and here I have to mention a tool that is basically indispensable for chip design - DA can convert the code language written by programmers into chip circuits.

If EDA is not a tool, then the designer has to draw the circuit diagram by hand.

In addition, EDA also has a simulation function, which can find the designer's code bugs, and find the functions and power consumption that need to be optimized. It is worth mentioning that the EDA tools are all foreign.

The third step is the physical implementation, which involves optimizing the chip circuitry, determining where each transistor is placed and how the transistors will interconnect with each other.

Finally, it is necessary to manufacture slices for the fab, such as TSMC and so on.

Normally, it takes 1-2 years to design a chip, except for the hanging, of course, and Ma Tian is the one who opens the hanging.

With a solid knowledge of Lv3 electronics, physics, informatics, etc., Ma Tian conquered Xia Wei's senior engineers with real talent and real learning, and Ma Tian could be heard training people in the R&D area in the first few days:

"You're using the wrong type definition here! Should use reg type! Why do you, a senior engineer, make such a low-level mistake? ”

"This circuit is not the optimal solution, you can change the AND gate to the AND AND gate. Don't question my vision, if I say it's wrong, it's wrong, if you don't believe it, go and simulate it now, if you're wrong, you'll have to change the optimal solution for me all night! ”

"Is the power consumption still high here? It's not a problem with the circuit design, maybe the hardware components are flawed, so I sent someone to simulate this circuit on the other side, and use a universal meter to measure the voltage and current one by one! ”

"Damn, are you going to question my math? Who gave you courage? Liang Jingru? This algorithm is definitely more efficient than your previous ones, give me this one of mine, don't believe you to write a test case to run! ”

……

Watching Xia Wei's engineers being scolded one by one, Zheng Shijian, Tang Jiefei and others seemed to see themselves at the beginning, and happily made a cup of coffee to watch the show.

"Well, this coffee is not refreshing." Tang Jiefei took a sip and complained.

"Nonsense, how long have you been up, you've been immune to coffee for a long time, okay, you overtime maniac!" Zheng Shi saw that he was not angry and said, Tang Jiefei worked overtime and was fierce, he was a person with mild obsessive-compulsive disorder, and he often finished writing a function in code before leaving work.

So it's the norm for him to work 24 hours straight.

This time writing the API interface is even more terrifying, and it is almost 30 hours of work.

This means that you have enough energy before you don't have a girlfriend, and you won't be like this after you have a girlfriend.

"I don't think I'm as fierce as the Xia Wei employees, they are the real overtime maniacs." Tang Jiefei denied that Xia Wei had a wolf culture, and individual employees worked overtime, and even he was willing to bow down.

However, Xia Wei's engineers were scolded and scolded, but none of them disagreed with Ma Tian.

Not to mention Ma Tian's honors, the questions that Ma Tian asked them to verify all prove that Ma Tian was right.

After a few times, they also became the only Ma Tianma, and Ma Tian was right when he said that he was right, and he was completely flat. It made Ma Tian more handy.

With the cooperation of a large number of senior engineers, Ma Tianjian described the function in Verilog language in just 3 weeks.

Then, after a week of debugging, the final chip circuit board was directly drawn.

Seeing that the design circuit worked well in the simulation, a group of people couldn't help but cheer anymore, and they could get the results out in a month, which was something that their group of engineers couldn't have imagined before.

And only Ma Tian in front of them took them to do it!

Nie Zhenyuan also looked at Ma Tian's back deeply, and was shocked in his heart. He couldn't remember how many times he had been shocked by Ma Tian in the past month, and Ma Tian was still refreshing the upper limit of his heart again and again.

How many identities does Ma Tian have, and why does he know so much about electronic circuits, physics, programming, etc., in addition to top mathematicians.

Is it true that learning math well can be done in a comprehensive way? Is mathematics really the key to other disciplines?

Xia Wei seems to be recruiting more mathematicians in the future. Nie Zhenyuan thought to himself.

Everyone present cheered, but Ma Tian's face was calm and excessive.

In his opinion, the chip design is nothing, today without his Ma Tian leadership, Xia Wei can design it with a little more time, the real difficulty is manufacturing.

The rise of a great power must start with the industrial machine, and there is still a long way to go.

Nie Zhenyuan came to Ma Tian's side and said sincerely: "Thank you Mr. Ma for your leadership during this time." ”

He was actually so excited that he wanted to shake hands with Ma Tian, but as soon as he saw Ma Tian's expressionless face, he immediately felt a kind of pressure and didn't dare to stretch out his hand.

Ma Tian smiled, and also recovered from the thoughts of chip manufacturing, and replied simply: "You're welcome." ”

After thinking about it, he added: "Actually, I think you can push back the time of the press conference and optimize some features!" ”

"Oh? Mr. Ma, please speak. ”

"For example, you can remove the bottom three keys!"

Now Xia Wei still retains three keys under the phone, which are return, home, and menu keys.

Ma Tian thought of the full-screen mobile phone in the future, but there is no button at the bottom, and returning directly is to return or cut the program by sliding down from the bottom.

"Are those three keys removed? In that case, it will be inconvenient for the user. Nie Zhenyuan asked.

"No, you can replace these three keys with other touchscreen functions, such as exit, and go back once by swiping up from the bottom. The main menu program can also be selected by double-tapping the screen, or directly pressing the finger all the way to the smallest screen instead of ......"

Ma Tian threw out all the concepts of the full screen of smartphones in the previous life, since he decided to help Xia Wei and Pingguo fight in the ring this time, it is better to help to the end.

Take the path of Pingguo in the previous life, so that Pingguo has no way out!

Ma Tian continued: "If you think about it, full screen is a new concept. Now there is also a key at the bottom of Pingguo, which is not as good as Xia Wei's real definition of a buttonless smartphone this time. ”

Nie Zhenyuan's eyes lit up when he heard this, "Mr. Ma, just do as you say, I'll go and apply to Mr. Ren, and redefine smartphones this time!" ”

Ma Tian nodded, the son can be taught, this time he will temporarily borrow Xia Wei to wrestle with foreign hardware giants, and wait for him to develop for a while.

……

Xia Wei secretly engaged in such a big thing with Ma Tian, and Pingguo was naturally not unaware of it.

Although Xia Wei kept it secret, they got the news as soon as the chip design drawings were handed over to the wafer factory TSMC to process the first sample chip.

"What kind of chip is this?" Yaye Sarri, who is the vice president of Pingguo, asked.

Standing in front of him was Loth Abate, a senior chip IC engineer from Pingguo, who replied in a low voice: "I can't tell what kind of chip this is." ”

Of course he can't see it, who can see what the function of a chip is in the first place? But what he can be sure of is that this is definitely not the main CPU chip.

Because it looks simpler on the diagram, there are many fewer crystal units than the main CPU chip.

"What is Xia Wei doing?" Yaye Sarri fell into deep thought, Xia Wei, as a leader in the field of communications, has long been watched by these giants, and every move has been specially watched.

Although Xia Wei's mobile phone is not a threat to them now, the biggest threat is Lei Jun's rice, but Xia Wei is a company that really has technology and is willing to research and development, and this is what they are most afraid of.

"Let someone take an electron microscope and scan the chip structure and take a closer look at what's famous." Yaye Sarri said.
