Rebirth 2010, the best

Chapter 277 Photographic Memory
Xu Ruochu didn't react much to Lu Yao's decision to go to Shenzhen.

Just go. If she misses him, she can just take a plane over there. Besides, she goes to Shenzhen often and has a house there.

Even after learning that Lu Yao was going to stay there for a long time, he told him to live directly at his home.

Of course Lu Yao couldn't go to her house... Otherwise, if the other crazy woman knew that the house belonged to Xu Ruochu, she would probably feel more excited and scream even louder.

As for that crazy woman...

She was a little angry at first, after all, she had asked Lu Yao to take her with him in advance.

She didn't care about HiSilicon's projects, but she was happy from the bottom of her heart just thinking about being able to stay with Lu Yao every day.

As a result, when a basin of cold water was poured on her, she immediately felt like she was about to explode.

Fortunately, Lu Yao arranged in advance and produced evidence to let her know that it was not her intention at all, but that Haisi did not "like her" at all...

The senior student calmed down and came to a conclusion.

Huawei is a garbage brand.

A fighter among the garbage.

But now that the matter is settled, if she wants to see Lu Yao, she can only go secretly on Saturdays and Sundays, and then she has to avoid Xu Ruochu...

This made the senior sister very unhappy.

Fortunately, the band will still have commercial performances on Saturdays and Sundays, so she can still fly across the country.

Coupled with Lu Yao's beating, it was considered a comfort that the small harem did not get into trouble.

And the happiest person was obviously Hu Li.

Shenzhen is much closer to Sanya than Shanghai.

She even came up with a bad idea and asked Lu Yao to commute.

Her private jet picked her up throughout the trip...

Lu Yao rolled his eyes when he heard this.

What you said is really true. A round trip flight costs hundreds of thousands. Is your family a bank? ...Oh, yes, that's fine.

Anyway, on Friday, November 11th, he went to Shenzhen alone.

But this time he learned his lesson and reported to Zheng Xiaofan in advance, telling him that he was going on a business trip to Shenzhen and that people from Huawei HiSilicon wanted to cooperate with him.

Zheng Xiaofan was not surprised by Lu Yao's business ability.

What's more, as long as he is in the country, he can go wherever he wants.

When Lu Yao asked him what to do about the twins and Luo Xuewei, he said directly:

"Look, the old problem comes back again, doesn't it? You are one of the links in this line, but without you, the rest of our comrades on this line will still stick to their posts. Besides, didn't I tell you that this is a long-term struggle? Not only do we have to find these snakes and rats in the same nest, but we also have to find the black sheep among them. So go ahead with confidence and follow your own pace. You don't have to cater to them, but they have to cater to you. You are the target with strategic value in their eyes. They are the ones who beg you, not you begging them."

After Lu Yao was educated, he felt relieved.

Come to think of it, it seems to be true. Whether it's Luo Xuewei or the twins... they don't need him to manage any relationships. Instead, they are more proactive.

This time, I really had no pressure at all. So I left on Friday morning.

And Huawei arranged business class for us.

It can be said to be comprehensive.

Sitting on the plane, he looked out the window at the sky which was becoming more and more dazzling, and his eyes gradually became empty.

My mind is full of all kinds of data I have seen about the two-way wireless transmission system in the LTE baseband.

Actually, optimization is something like this... It sounds simple: find the problem, analyze the problem, and come up with a solution to the problem.

In this project, we only need to propose an optimization method, and then implement the improvement plan through FPGA to complete it.

It’s said to be simple, but the difficulty… doesn’t seem to be there.

The LTE baseband in the previous life was almost worn out, so it was not difficult for him.

At present, its biggest problem is that the memory is occupied. To solve this problem, we need to improve and optimize the traditional cross-correlation detection algorithm. If we use 64-point FFT calculation, the amount of calculation seems to be not small. So in order to reduce its calculation amount...

After pondering for a while, he took out a notebook from his bag and wrote a line: Before performing cross-correlation detection, sample the signal to be processed X times and list the formula.

After writing it, he thought for a while and continued to write: If the sequence is symmetrical, it can be simplified. You can try 16 times sampling, and the local main synchronization data will be changed from 1024 points to 64 points. Then list the formula to reduce the need for complex algorithms - similarly, perform cross-correlation calculations on the receiving link and the local storage main synchronization sequence... (crossed out). Similarly, the demand for logical resources is huge. Choose another solution...

He was thinking as he wrote.

Before he knew it, the flight attendant came over to remind him if he needed anything to drink.

He asked for a glass of water and then said nothing more.

When he came to his senses again, it was the flight attendant who reminded him to put away the table.

Lu Yao stared at the stewardess for a while, then nodded belatedly. After putting away the table, he looked at the two pages of notebooks filled with dense writing, thought for a moment, and put them away.

This is his optimization plan for the overall baseband optimization algorithm, which is more detailed and specific than what he said in the previous chat with Huang Feng. It even includes some ideas for the subsequent CORDIC module implementation.

Unfortunately... I was interrupted by the flight attendant before I could finish.

But that’s okay.

He already has the overall idea.

And it's very detailed.

Just follow this line of thought and there will basically be no problems.

He rubbed his temple tiredly.

That's the downside of overusing your brain... Too bad, if only there was a pill like the one in the movie Limitless.

Apart from anything else, at least in the movie it seems to be very helpful for people who do mental work...

Too bad...it's just a movie after all.

As he spoke, he put the notebook in his bag and took out a medicine bottle.

He poured out a health-preserving pill from it, put it in his mouth, and swallowed it with water.

He has been eating this thing and he has to admit that it is indeed useful.

The most intuitive feeling is that it improves sexual function... Yang Ying obviously understands it best.

But what made him persist even more was what You Run said when he asked him about the medicine when they went out to play together before: "Those who are wise will be rewarded by Heaven. You will definitely be fine if you take it."

He thought it made sense...so for the sake of his life, one pill a day was a must.

As for the side effects…

It might not matter in the Magic City, but in Shenzhen, he really needs to think about it...

Well, my girlfriend is back anyway... her family owns a bank, so they have money. I can just commute by plane.

While thinking about these things to relax my brain, outside the window, the outline of the former small fishing village, which is now a municipality with high-rise buildings, has come into view.

When he got off the plane and picked up his luggage, he received a call from Huawei staff.

Then I saw them holding signs at the exit.

After everyone got into the car, Lu Yao was already drowsy.

As if noticing his fatigue, the two staff members immediately asked if they wanted to change the contract signing time to the afternoon so that he could go back and rest.

Lu Yao refused, it was just a signature anyway.

It won't waste much time.

So the car drove through Shenzhen, a city he was unfamiliar with, and then arrived at Huawei's headquarters.

Huang Feng had been waiting there long ago.

"Haha, junior brother."

"Senior brother."

Lu Yao smiled slightly, then took out a notebook from his pocket:
"Give."

"what is this?"

Huang Feng took it with some doubt.

Lu Yao shrugged, his tone was so casual:
"I was just killing time on the plane and wrote out a... let's call it a detailed version of the optimization ideas. But I didn't finish it because the flight attendant asked me to put away the tray table, so I didn't continue. You take a look at it first, I'll go sign the contract with them first."

"Uh... ok."

Huang Feng nodded:
"If you go, I won't go in. I'll wait for you here. Let's go out for lunch at noon."

"it is good."

Lu Yao responded and followed the staff directly into the elevator.

Huang Feng sat in the leisure area next to him and opened his notebook.

This notebook is new.

This is also Lu Yao's habit. He is used to taking out a brand new notebook for each project, so that when he searches, he will not be messy, and the data of other projects will not be mixed. And when he looks for information in the future, he can take out these classified notes for reference, so that he can find it intuitively and clearly.

Lu Yao's handwriting is not ugly either. Although it is not as exaggerated as the good ones, it can at least be clearly recognized.

Even Huang Feng's first thought when he saw his two-page optimization plan was that this handwriting is really suitable for making reports. Even though handwritten reports have long been eliminated, if it were put in those days, this neat report would definitely be very popular among scientists of that era.

With this idea in mind, he saw the first line of words: Before performing cross-correlation detection, sample the signal to be processed X times...

He blinked and continued looking down.

Lu Yao's handwriting is very clear and written in standard style, so there is no possibility of misunderstanding.

What to do in the first step and what to do in the second step are written very clearly.

But Huang Feng was completely speechless when he saw half of it. Completely speechless.

There is a line of text that reads: Received RF data I and Q link data, and the received data bits are 16 bits, and the stored data bits are 6MS, that is, the depth is 92160. According to this data, the dual-port RAM corresponds to the respective port data:
"ADDRA: 17, DINA: 16, ENA: 1, WEA: 1, CLKA: 1, ADDRB: 17..."

He didn't finish reading the data, he just put down his notebook and took out his phone.

"Dudu... Hey, Brother Huang. Go ahead."

"Are you in the lab?"

"Here I am."

"Okay, now find the column about the received RF data I\Q link in our LTE baseband bidirectional transmission."

"Okay, wait a minute."

After a moment, the other end of the phone responded:

"Already found."

"Well, report the RAM data to me."

"Okay, ADDRA17, DINA16..."

As the voice came from the other end of the phone, Huang Feng's expression gradually became strange.

After comparing all the data with the notebook, he asked directly:

"Have we sent this data to anyone else?"

"Of course not. How could it be sent to anyone else?"

"……Sure?"

"Sure. Huang, what's wrong?"

"…It's okay, go ahead and do your work."

Huang Feng hung up the phone directly.

In fact, he asked the following questions purely out of subconscious reaction.

Although this kind of data is not top secret, it is the result of the laboratory and will definitely not be disclosed.

Otherwise you will be sued.

Moreover, this is just RAM data and does not represent anything.

It is very important in the research process because research is a chain of links.

But if taken alone, it is just a set of data and is completely useless.

The reason why Huang Feng asked this question was very simple.

He…was actually quite confident in his memory. He also remembered very clearly that, first of all, he had never sent this data to his supervisor. His supervisor had indeed seen it, when he showed him the research results when he came over some time ago.

As a mentor, I naturally don’t have to worry too much about projects of this level.

As for Lu Yao...he has actually seen it too.

After all, it was he who came up with the optimization solution.

But this is what makes this matter so strange.

He just read it once, without any paper reports to check or study, he... just read it once.

It's still a very cursory look.

When looking at it, an optimization plan was proposed.

And now... the detailed plan in my hand is so exaggerated that a certain set of... very inconspicuous RAM link data from the 58-page data report is written on the notebook in my hand.

What does this mean?
This means...either he saw the report through other channels and did his research.

But this possibility is almost equal to 0.

impossible!
Absolutely impossible!
If the information was really leaked...there is no possibility of this happening at all.

Not almost, but almost equal to 0.

After this reason is ruled out, there is only one possibility left.

In just those few minutes, my junior fellow student wrote down... God knows how much content in the report.

As precise as a camera.

Once you have seen something, you will never forget it...

"Do you want to be so exaggerated?"

Huang Feng muttered to himself subconsciously.

What kind of monster is this?

It would be fine if he only remembered a rough idea... Huang Feng even asked himself, if it were him, he would at most have a general impression of the report, but he would definitely not remember the detailed data... let alone the RAM data in front of him which is not that important in the whole process.

But he wrote it out, word for word.

Does this person really have a photographic memory?
This is... the top scorer in the college entrance examination, who went directly to graduate school after his freshman year... the value of a genius?
"Senior brother."

At this time, a voice sounded.

Huang Feng subconsciously looked up and saw Lu Yao with a smile on his face.

To be honest, my junior brother is... a very comfortable person to get along with.

First of all, his attitude is always friendly and he is not arrogant. Although we are not that familiar with each other yet, we don’t know his true character. But for new friends who we meet for the first time or even those we are not very familiar with, whether it is attitude, chatting, or all aspects, it is very comfortable to get along with him. He is a person who will not leave a bad impression on others.

From this point of view, it shows that my junior fellow student has a high emotional intelligence.

People with high emotional intelligence will do well wherever they go.

People with high IQs... often have some unique characteristics.

But...he didn't.

He has high emotional intelligence and a brain that is... simply like a monster.

Looking at Lu Yao approaching, he didn't ask "Is it done?" or anything else, but asked completely out of instinct:
"Junior brother, did you write down all the data here?"

Lu Yao was stunned.

He glanced at the opened notebook and nodded with a smile:
"correct."

Still “right”?
Huang Feng's mouth twitched, and he pointed at the line of RAM data:

"You remember everything? ...All of it?"

"Yeah, almost."

Lu Yao nodded again.

The twitching of Huang Feng's facial muscles had spread from the corners of his mouth to his cheeks.

All.

Everyone remembers...

What should I say?
He found himself speechless.

"what's wrong?"

Looking at Lu Yao's innocent expression, Huang Feng suddenly sighed:
"Ugh……"

As he spoke, he closed the notebook he hadn't finished reading and stood up:
"I finally know what a genius is..."

"Uh."

Lu Yao was stunned for a moment, then smiled and said:
"Are you praising me? I feel embarrassed."

"Don't... I'm not exaggerating, I'm just repeating the facts."

Huang Feng said with emotion:
"It's so irritating to compare people to each other."

Then, he returned the notebook to him:
"Let's go, I'll take you to dinner."

"Row."

Lu Yao smiled slightly.

Although it was not intentional, it seemed that my behavior really shocked this senior brother.

That's good too, it will make it easier for us to continue our cooperation in the future.

As for whether or not I am a genius...

It doesn't really matter.

There are so many geniuses...

It’s like mathematics. People say that mathematics is a group of mortals lying on the ground watching a few gods creating the world in the sky.

In the field of scientific research, he never considered himself a genius.

If I really want to say...

He is just standing on the shoulders of giants.

Who allowed him to be reborn?

As for what his senior brother was thinking, he didn't care much.
