My technology affects the whole world

After the meeting, everyone went to prepare individually, setting up the environment where it was necessary, and looking at the code when it was necessary.

Nie Zhenyuan found Ma Tian who was leaving: "Mr. Ma, wait a moment, there are some things we may not have explained clearly yet."

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

"That's not it. You already made it very clear about the technical plan at the meeting, which is about the settlement of remuneration between our two companies." Speaking of this, Nie Zhenyuan was also a little embarrassed.

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

Ma Tian probably wouldn't even look down on it if given a few hundred million.

There is also the cost of the voice assistant. The voice assistant is not patented, so I don’t know how to calculate it.

But it is impossible not to give Ma Tian a reward, and I dare not not give it even if it makes no sense.

Ma Tian also laughed when he heard this. This matter was indeed not easy to handle from Xia Wei's point of view.

"The remuneration of the two companies should follow the normal process. Tianyu's patent is Tianyu's patent. You can pay as much as you should, except that I am helping them for free.

But I hope you will remember that this time, I will stand up for the high-end domestic mobile phone market and crack down on Pingguo’s arrogance on our side! "

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

"Mr. Ma, don't worry, the high-end domestic mobile phone market will not be occupied by foreign countries. We, Xiawei, will always be at the forefront."

Ma Tian nodded, left a soft "Not bad", and went back to his office to read the code. As the chief engineer, he must understand everything. Xia Wei's source code must also carefully look at the architecture. Good at coordinating the overall situation.

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

Because the chip design is very complex, the number of internal circuit units in a chip can reach tens of billions. Anyone who has had a little contact with the chip field knows how difficult it is.

Even if it's not the main CPU chip this time, but just a module chip, Ma Tian estimates that there will be millions of circuit units.

Chip design is roughly simplified into three steps in popular language:

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

A mobile phone is only as big as the palm of your hand. You must consider where to place the chip appropriately, and it cannot consume a lot of power because you have to consider standby power and security certification.

What Ma Tian wants to design this time is a speech recognition assistant. Its function is naturally to convert speech signals into digital signals, which are 0 and 1 that the machine can recognize.

The second step is to write the required functions using verilog or VHDL hardware description language. Here I have to mention a tool that is basically unavoidable in chip design - EDA. EDA can convert the code language written by programmers into chip circuits.

If there is no EDA tool, the designer has to draw the circuit diagram by hand.

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

The third step is physical implementation, including optimizing the chip circuit, determining the placement of each transistor and how to interconnect the transistors.

The last step is to make slices for the wafer factory, such as Moss Semiconductor and so on.

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

With his solid knowledge of Lv3 electronics, physics, informatics, etc., Ma Tian conquered Xia Wei's senior engineers with his true talents and knowledge (cheating). In the first few days, you could hear Ma Tian working on research and development District trainer:

"You used the wrong type definition here! You should use the 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 a NAND gate. Don't question my vision. If I say it's wrong, it's wrong. If you don't believe it, go run the simulation now. If you're wrong, you'll have to give it to me all night long. I’ll come up with the best solution!”

"Is the power consumption still high here? It's not a problem with the circuit design. There may be defects in the hardware components. Send me someone to simulate the circuit on the other side and use a multimeter to measure the voltage and current one by one!"

"Damn it, are you going to question my math? Who gave you the courage? Liang Jingru? This algorithm is definitely more efficient than your previous ones. Use mine. If you don't believe me, write a test case and run!"

…

Seeing Xia Wei's engineers being scolded one by one, Zheng Shijian, Tang Jiefei and others seemed to see themselves in the past, happily making a cup of coffee and watching the show.

"Oh, this coffee isn't very refreshing." Tang Jiefei complained after taking a sip.

"Nonsense, how long have you been staying up? You've already become immune to coffee, okay? You overtime maniac!" Zheng Shi said angrily. Tang Jiefei worked overtime violently. He is a patient with mild obsessive-compulsive disorder. When coding a function, it is often done before getting off work.

So it's normal for him to work 24 hours a day.

Writing the API interface this time was even more terrifying, almost 30 hours of work.

This means that I was full of energy before I had a girlfriend, but I won’t be like this after I have a girlfriend.

"I don't think I'm as strong as those Xiawei employees. They are the real overtime maniacs." Tang Jiefei denied that Xiawei has a wolf culture, and some employees even put him at a disadvantage when they work overtime.

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

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

After a few times, they also became just following Ma Tian's lead. Whatever Ma Tian said was right, they were completely at peace. It actually made Ma Tian more comfortable in commanding.

With the cooperation of a large number of senior engineers, Ma Tian was able to describe the function in Verilog language in just 3 weeks.

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

Seeing that the designed circuit was running well in the simulation, a group of people couldn't help but cheer. They were able to produce the results in just one month. This was something that their group of engineers would never have thought of before.

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

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

How many other identities does Ma Tian have? Why does he know so much about electronic circuits, physics, programming, etc. besides being a top mathematician?

Is it true that if you learn mathematics well, you can master everything? Is mathematics really the key to other subjects?

It seems that Xia Wei will recruit more mathematicians in the future. Nie Zhenyuan thought.

Everyone present cheered, but Ma Tian's expression was extremely calm.

In his opinion, it was nothing to design the chip. Without Ma Tian's leadership today, Xia Wei could have designed it if he spent more time. The real difficulty was manufacturing.

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

Nie Zhenyuan came to Ma Tian 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 when he saw Ma Tian's expressionless face, he immediately felt a pressure and did not dare to extend his hand.

Ma Tian smiled, recovered from his thoughts about chip manufacturing, and simply replied: "You're welcome."

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

"Oh? Mr. Ma, please tell me."

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

The current Xiawei mobile phone still retains three keys at the bottom, namely return, home, and menu keys.

Ma Tian thought about later generations of full-screen mobile phones, which would have no buttons at the bottom. Returning to the screen would simply be a matter of swiping down from the bottom to return or switch to programs.

"Remove those three keys? In that case, will it be inconvenient for users to operate?" Nie Zhenyuan asked.

"No, you can use other touch screen functions to replace these three keys. For example, to exit, just swipe up from the bottom to return. To select the main menu program, you can also double-click the screen, or directly press it with your finger. The smallest screen replacement..."

Ma Tian threw out all the concepts of full-screen smartphones in his previous life. Since he decided to help Xia Wei and Ping Guo fight in the ring this time, he might as well help him to the end.

Follow the path of Pingguo in her previous life, leaving Pingguo with nowhere to go!

Ma Tian continued: "Think about it, full screen is a new concept. Now Pingguo also has a button at the bottom. It is not as good as Xia Wei's true definition of buttonless smartphone this time."

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

Ma Tian nodded. Children can be taught. This time, I will temporarily use Xia Wei to arm-wrestle with foreign hardware giants, waiting for him to develop for a while.

…

Xia Wei secretly engaged in such a big deal with Ma Tian, ​​so Ping Guo was not unaware of it.

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

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

Standing in front of him was Los Abate, one of Pingguo's senior chip IC engineers. Los Abate replied in a low voice: "I can't tell what kind of chip this is at the moment."

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

Because the picture looks relatively simple, the crystal unit is much smaller than the main CPU chip.

"What is Xia Wei doing?" Yaye Sari fell into deep thought. As a leader in the field of communications, Xia Wei has long been watched by giants like them, and his every move is monitored by someone. .

Although Xia Wei's mobile phone does not pose a threat to them now, and the biggest threat is Lei Jun's rice, Xia Wei is a company that truly has technology and is willing to research and develop. This is what they are most afraid of.

"Let someone use an electron microscope to scan the chip structure and take a closer look at what's going on." Yaye Sari said.
