At this time, the black military-license car had stopped, and Gui Changshu and a tall old man got out of the car.This old man has white temples, a face with Chinese characters, and a pair of thick sword eyebrows, and he has an extraordinary temperament.
"Xu Dong, you come to pick up the car in person, how can I stand it?" Seeing Xu Zhenming hurriedly approaching, Gui Changshu laughed and joked with Xu Zhenming.He has a very close relationship with Xu Zhenming, and he can make such a joke.
Xu Zhenming shook hands with him and greeted him, "Did you always fly to Suning City last night?"
"Yeah, the task is urgent and we have to hurry. This is Professor Tao He from Suning Astronautics University and an academician of the Chinese Academy of Sciences." Gui Changshu didn't forget, and smiled and introduced the tall old man beside him to Xu Zhenming.
Hearing this, Xu Zhenming couldn't help being startled, "Academician He? If I didn't guess wrong, this person is the Academician He who studies the early warning aircraft." Although he thought so in his heart, Xu Zhenming did not say anything.
For such confidential items, if he casually revealed a little information, he would be listed as a suspicious object, and someone would follow him every day.
Thinking of this, Xu Zhenming shook hands with Academician He very politely, "Fortunately, Academician He, let's go upstairs first."
Soon after, the three settled down in Xu Zhenming's office.
At this time, Academician He, who was sitting across from the glass coffee table, scanned Xu Zhenming's office once, and stopped talking.
Seeing his appearance, Gui Changshu shook his head and smiled, "Don't worry about him. His office has undergone special treatment and is absolutely confidential. My usual important confidential items are discussed here."
"Oh..." Academician He nodded slowly, picked up the teacup on the glass table, picked up the lid of the bone china cup, and flicked the green tea leaves on the teacup with the lid edge, without speaking.
All this fell in Xu Zhenming's eyes, which made Xu Zhenming even more curious, "Academician He is so cautious about what important project is." Even though he thought so, he did not take the initiative to speak.
"Xu Dong, I heard that island companies have increased their prices for auxiliary materials such as photoresist and high-purity HF reagents. Will you be affected?" At this time, Gui Changshu did not say his intention, but proposed An unrelated question.
He told Xu Zhenming that this trip to the headquarters of the Yiming Group Company was to remind Xu Zhenming that "islanders are likely to target Chinese chip companies and interrupt the supply of these chips and auxiliary materials for the semiconductor industry."
After saying this, he sighed long.
China used to produce these auxiliary materials by itself.With the shrinking of the market and the advent of the market economy, those companies that built at no cost have now closed down.Therefore, Hua Guo began to beg for help again.
"Hahahaha..." At this time, Xu Zhenming burst into laughter.
"We have known that they will come to this hand for a long time, except for the auxiliary materials with a relatively short shelf life, we have already stocked them. Even if the photoresist with a short shelf life, we have signed a contract with Europeans, although the price is a bit higher, But it’s much safer."
Xu Zhenming told Gui Changshu that the Yiming Group Company did not take pictures of the islanders. In fact, they had already prepared.
He knew that the islanders had played this trick on the Korean enterprise, how could he not be guarded?
"That's good, that's good!" After hearing Xu Zhenming's explanation, Gui Changshu finally breathed a sigh of relief.
As long as the production of Yiming Group is not affected, the production of Longteng Computer will not be affected.
Nowadays, all the enterprises, research units and combat units under the Longbow Group are engaged in major operations of computer upgrading.Don't make a big mistake with Longteng Computer's computers.
Since the Yiming Group Company is very safe here, Gui Changshu decided to give Xu Zhenming a big gift package, "Before I came here, the head of the headquarters had issued a recent instruction: Longteng Computer Company’s 8-inch silicon wafers, use Yiming Group The company’s domestically produced products. No matter how the prices in the international market move, they must do so."
Hearing this, Xu Zhenming still felt very much.
"President Gui, please rest assured that our group company's quotation must be fair and just." He patted his chest to ensure that Yiming Group will not adjust the ex-factory price of 8-inch silicon wafers.
The two discussed these two key issues, and Gui Changshu told Xu Zhenming with a relaxed expression: "The head of the headquarters has assigned a new task for the 9701 project."
At this time, Gui Changshu entered the topic and answered Xu Zhenming's doubts.
He told Xu Zhenming that the Longbow Group was preparing to develop an early warning radar and supporting early warning aircraft.
This subject is called the 9701 project and currently requires a large set of chipsets.Academician He is responsible for the research and development of the 9701 chipset.This is also the purpose of Academician He coming to Yiming Group.
Hearing this, Xu Zhenming nodded and said in his heart: "As I imagined. With the emergence of our Yiming Group, many scientific research projects in China have undergone fundamental changes."
In another time and space, China's early warning aircraft project started relatively late, and it was some help provided by a certain country in the Middle East.The main reason for this is that China's electronic technology is weak and it can't keep up with the pace of the times.
But now this situation has changed a lot. With the release of Longteng EDA, the scientific research unit of the Longbow Group can reverse design based on foreigners' electronic products.
As a result, the sophistication of domestic electronic components may have gaps in foreign countries, but there is definitely no gap in product performance.Longbow Group wants to start early warning aircraft project in advance, it is just a matter of smooth flow.
Thinking of this, Xu Zhenming smiled at Gui Changshu, "As long as we can help, our collective company is obliged to do so despite President Gui's orders."
"Hahahaha!" Gui Changshu heard the words and touched the forehead whose hair was becoming thinner.
Upon seeing this scene, Academician He opened his briefcase, took out a pile of printed materials, and handed it to Xu Zhenming.
"We need a set of YJ-010970 chipset, a set of YJ-02501 chipset, and a set of YJ-0506 chipset. The function requirements of the chipset have been marked on the above. Xu Dong, when can your group company Give a reply?"
Academician He stared at Xu Zhenming intently, wanting to get an answer immediately.
But Xu Zhenming is not good at this kind of microelectronics technology.Even if he can, he cannot give a clear answer now.
Looking at the opposite academician He, he smiled bitterly and said: "Old He, your question is a bit complicated. We have to discuss it through internal meetings."
"Hey...this is the truth." Academician He leaned back a little disappointed after hearing this.
Since receiving this task, he has been in a state of anxiety.As a veteran aviation person, he wants more than anyone else to have a warning eye in the blue sky of China.This is very important because it concerns the safety of national airspace and the safety of fighter operations.
But how can the reality be so fast?
Looking at the tall old man Academician He in front of him, Xu Zhenming could also guess some of his thoughts.
"Old He, I'm very sorry. I will organize an internal technical meeting soon. I can guarantee that our group company can reply to you by 5 o'clock tomorrow afternoon at the latest." Xu Zhenming stood up with a wry smile and prepared to see off the guests. .
He has an urgent task now, but he has no time to accompany these two old men.
Gui Changshu knew Xu Zhenming’s character, so he stood up and smiled and said, "Xu Dong, we will return to Suning Avionics Research Institute now and visit you tomorrow. It’s just a pity..."
"What is such a pity?" Dean He looked at Gui Changshu in confusion.
Gui Changshu smiled and told him that the "Thousand Miles of Fragrant Fragrance" in the Yiming Group's cafeteria was very delicious. I left so early today and I had no good taste.
Hearing this, Academician He frowned, "Lao Gui, when is it now, do you still want to eat delicious food? Hey..."
"Hahahaha! Don't eat, let's go!" Gui Changshu waved his hand, shaking hands with Xu Zhenming and leaving.
Xu Zhenming did not stay in the office after sending the two people away, but drove directly to He Changlin's laboratory.
He will organize a meeting immediately to arrange the design tasks of the YJ-010970 chipset, YJ-02501 chipset and YJ-0506 chipset.The current situation can be described as a mountain of military orders, and he has to step up his task.
"Xu Dong, I’d like to report a good news to you. Our YM-PLC has been officially developed successfully. This time, we listened to your opinions. We did not imitate German Siemens products, but adopted a new design. The instruction set of ASCI code is our own."
Seeing Xu Zhenming's hurried knock on the door and entering, He Changlin raised his eyes to look at Xu Zhenming, with a smile on his face.
His news was obviously very good, which made Xu Zhenming's mood much better.But Xu Zhenming has no time to pay attention to this matter."Old He, let's hold a meeting right away to discuss an important confidential project." His expression was relaxed, but his tone was serious.
Seeing Xu Zhenming's expression like this, couldn't He Changlin react?
The last time was the 1809 project of Northern Aircraft Corporation, and Xu Zhenming was so serious.The task of this time is definitely not easy!
"Okay, Mr. Xu, ten minutes later, we will gather in the secret meeting room." Thinking of this, He Changlin narrowed his smile, picked up the red phone on the desk, and began to order the meeting.
Ten minutes later, He Changlin's laboratory was in the secret meeting room.
The engineers who came to the conference room were already sitting at the small conference table, quietly waiting for the arrival of Xu Zhenming and He Changlin.
Seeing this scene, Xu Zhenming was quite proud.In any case, the engineers under his team have combat effectiveness and can undertake key projects of the Longbow Group.
"This can be regarded as serving the country?" Xu Zhenming asked himself contentedly.He gave the information in his hand to He Changlin and asked He Changlin to chair the meeting.
After a while, Xu Zhenming came to the main seat in the middle of the conference table.He didn't sit down, glanced sharply like a sword.
"Dear colleagues, I have a 9701 project with the highest level of confidentiality. Before the meeting, everyone must sign a confidentiality agreement." Xu Zhenming announced the project regulations with a serious expression.
As he spoke, he glanced around again, wherever his eyes were, they were the eyes of the engineers.
Eyes are the windows of the soul, and Xu Zhenming wants to see the wishes of these people from his eyes.
Engineers like to advocate freedom, and few people like to be bound by such secrecy.But Xu Zhenming certainly cannot compromise. Engineers who don't want to sign a contract can't know the status of the 9701 project.
Even if they knew the content of today's meeting, it would actually not be harmful to the 9701 project.But Xu Zhenming dared not do this.Fortunately, the engineers who came to the meeting today were very cooperative and completed the signing process in a very short time.
Next, we will watch He Changlin's performance.
"Dear colleagues, there are a total of three chipsets for our task, namely YJ-010970 chipset, YJ-02501 chipset and YJ-0506 chipset. This YJ-010970 chipset, I think it should be automatically distinguished, automatically identified, A chip that automatically corrects. What do you think?"
He Changlin turned the data into a picture and projected it on the wall through the camera.
After his analysis, the YJ-010970 chipset is a set of signal processing chipsets; the YJ-02501 chipset is a signal input and output chipset; as for the YJ-010970 chipset, it should be an ASIC code chipset, which can use CPU To name.
Hearing his analysis, Xu Zhenming understood why Gui Changshu was so relieved to hand over the 9701 project to Yiming Group for design.
The principle of this chip is very similar to other chips, and there is no fuss.The only requirement is that the chip must be very resistant to impact.After all, these three chipsets are for military use, and the combat environment is very harsh, and the chipsets must be durable.
Thinking of this, Xu Zhenming breathed a sigh of relief, and was very confident in his reply to Academician He tomorrow.
"Mr. He, I think there are still omissions in the function of the YJ-010970 chipset. Customers seem to want our chipset to have a certain degree of artificial intelligence. Look at this sentence." At this time, a young man with highly myopic glasses suggested Different views.
This person's name is Yanbo, and he is a high-achieving student who graduated from the Department of Computer Science of China University of Science and Technology.Yanbo gave up the opportunity to study abroad because he likes to major in microelectronics.
He came to Yiming Group Company as an apprentice.Even so, the young man was still happy.In this way, he grew up very fast, and now he has become a backbone engineer.
"This is the so-called reward for what you give, right?" Seeing Yanbo's speech, Xu Zhenming couldn't help feeling a little.He had interviewed this person personally, so he was somewhat impressed.
"Eh? The language is somewhat reasonable. Although the other party didn't say it very clearly, it was actually hinting that we have artificial intelligence instructions."
"Now this year, the chip instruction set with artificial intelligence, and the integrated transistors are so many that we can't afford it."
"Shao Gong, we don't care about this, the customer will pay the bill."
After listening to the dialect of Yanbo, the engineers in the conference room began to express their opinions.They think that Yanbo's idea is very reasonable, and customers just need instructions from artificial intelligence.
In this era, artificial intelligence research is still at the stage of software algorithms.For example, the use of software to achieve a game between man and machine is actually a kind of artificial intelligence.
But if it is embodied in the form of ASIC code instruction set, it will be a bit early, and at least it will have to wait for the fourth-generation lithography machine to be developed.
So, are the requirements of that academician He too high?
At this time, the black military-license car had stopped, and Gui Changshu and a tall old man got out of the car.This old man has white temples, a face with Chinese characters, and a pair of thick sword eyebrows, and he has an extraordinary temperament.
"Xu Dong, you come to pick up the car in person, how can I stand it?" Seeing Xu Zhenming hurriedly approaching, Gui Changshu laughed and joked with Xu Zhenming.He has a very close relationship with Xu Zhenming, and he can make such a joke.
