Yang Jie said with a smile: "I also imagined how I would start if I designed this digital program-controlled switch, but I think the design ideas of these foreign telecom companies are similar, and they will also use the idea of multi-module connection." Multi-module interconnection has high requirements for bus technology, and I estimate that with the current technology in China, it is already great to achieve 32 modules. ”

Naturally, he would not say that he worked in Huatai in his previous life, and he was very clear about the development of Huatai's previous technical route.

Tang Zhenren is most concerned about the development of Wanmen machine at the moment, and when he heard Yang Jie say this, his eyes suddenly flashed: "You still know how to program control switches?"

Qin Yifei also immediately realized Mr. Tang's intentions, and he said to Yang Jie with a warm face: "Xiaojie, judging from the control chip you designed and the control software you wrote, you are very strong in the IC, both soft and hard, do you want to see our board and bus software development? If you can give some advice, it will also be an inspiration to us." ”

"I have learned assembly language, algorithms, communication protocols, and multi-bus development, and I can go to Huatai to take a look, but there is no guarantee that I will be able to give effective advice. Although Yang Jie is also very proficient in these, he is not sure what technical fierce people Huatai has dug up, and may have achieved a major technological breakthrough in the switch.

Tang Zhenren was ecstatic when he heard Yang Jie's words: It seems that he really dug up a treasure this time!

"Director Yang, this time I want to ask your kid to follow me to Huatai Company, you won't object, right?"

"It is this kid's luck to be able to follow Mr. Tang to Huatai Company, and it also opens his eyes to this kid and lets him know what is going on outside the mountains and there are people outside the people!" Yang Minghui said with a smile.

He knows that Huatai Company is a high-tech enterprise, and there are many technical talents in it, if his son can have more contact with these technicians, this is a very good thing for his son, and he will naturally not disagree.

"Xiaojie, after I go to Huatai, I will take you to meet our development team. In our project team, the youngest Song Xiaobing is only 19 years old this year, he graduated from the junior class of the University of Science and Technology of China, I think you must join him to become good friends. Qin Yifei said with a smile on the side.

Yang Jie also knows that the reason why Huatai's program-controlled switch development project is famous in Huaxia is because Huatai has a large number of technical backbones, and later some technical backbones or started their own businesses or joined other technology companies as important technical leaders, and later this project was even known as Huatai's Huangpu Military Academy project.

Yang Jie is also very happy to know these technicians, after all, even if he is a reborn person and has a large number of technical patents, but if there are no large number of technicians to help him, many things can only be some technical drawings, and cannot become real technical products.

Yang Jie smiled and said, "Then I'm going to go even more!"

The next day, Yang Jie and Tang Zhenren and his party drove towards Pengcheng by car.

After running around for almost a day and a night, Yang Jie also came to the high-tech development zone where Huatai Company is located that night.

"Yifei, you take Xiaojie to the dormitory for a night's rest, and you must take good care of your daily life. Tang Zhenren said to Qin Yifei.

"Don't worry, Mr. Tang, I will take care of him as if he were my brother. Qin Yifei said.

"Xiaojie, I'm really looking forward to your next performance. Tang Zhenren said to Yang Jie with anticipation.

"Don't worry, Mr. Tang, I will definitely take out all my skills. Yang Jie nodded.

Yang Jie then followed Qin Yifei to the dormitory where he lived, and his room had two small rooms.

"You've been living with me all this time. Qin Yifei said to Yang Jie with a smile.

"Brother Yifei, I live with you, so I won't disturb you and your girlfriend, right?" Yang Jie said with a smile, just now he also saw a photo of Qin Yifei and a girl.

"My girlfriend is over there in Zhuhai, and she doesn't usually come. Qin Yifei grinned.

Early the next morning, Yang Jie followed Qin Yifei to the development department.

At this time, Yang Jie saw through the glass that in the huge workshop next to him, several engineers were busy facing the oscilloscope, and there were a bunch of interface cards, geophones, multimeters, and power devices piled up on the long workbench...... There were also a few engineers working on the thick amount of data in their hands.

Seeing the scene in front of him, Yang Jie felt an extra cordial feeling in his heart, he was too familiar with such a scene.

"You must have been to the laboratory of the Institute of Electronics, right? Look at the development equipment we have here, it's enough, right? The bus development equipment of the German SUSS company alone costs more than 200,000 ......."

Qin Yifei introduced the equipment to Yang Jie, and then said: "At present, we are solving the problem of high CPU occupancy, since you can design the chip, then can you do some debugging from the perspective of the chip?"

Qin Yifei didn't expect Yang Jie to come up with any clever tricks all at once, just because in the past few days, the project team has been stuck in the CPU occupancy problem, and the CPU occupancy rate has soared to the red line for a long time.

Hearing Qin Yifei say this, Yang Jie immediately knew in his heart where the problem of this CE18 program-controlled switch appeared, this kind of product from 20 years ago, and related technology was naturally not a secret to him.

"Brother Yifei, I know that the CE18 device uses Intel's 486 processor, and this situation is very likely to be caused by abnormal traffic processes. In the case of peak traffic conditions, for some packets, the 486 processor is prone to address drift, and will repeatedly switch between multiple addresses, falling into a loop, so that the CPU usage soars. ”

Qin Yifei's eyes lit up suddenly: "I have also thought about the situation you mentioned, but I haven't been able to think of any way, do you have any solution?"

He still wanted to solve this problem by using hardware, but after hearing Yang Jie's words, the window paper in his heart suddenly seemed to have been poked open, and his voice became excited.

Qin Yifei also didn't expect that Yang Jie neither looked at the data nor tested and analyzed it on the computer, but directly said a reason based on theoretical analysis!

He has been thinking about how to solve this problem recently, and when he heard Yang Jie say this, his intuition told him that this is probably the way to really solve this problem!

"The solution is to use a large amount of data for debugging, and then catch out the data packets that cause an exception each time and extract the feature code. ”

"And then?" Qin Yifei asked excitedly.

"After extracting the feature code, write a patch, use the feature code to analyze the data, and specifically process the data with abnormal CPU usage. This program can be written into the control software and automatically executed when the CPU usage increases. ”

"That's a great way to do it!"

Qin Yifei slapped excitedly: "Xiaojie, you are really a treasure! Mr. Tang's vision is really nothing to say!"

"Brother Yifei, analyzing specific feature codes and writing programs, this is a very complex project, all engineers need to analyze and debug one by one, which is a hard job. ”

"Haha, we engineers come to Huatai is not to be comfortable, I think Mr. Tang is right, if we do not master our own core technology, our country's products will be stuck by foreign companies with patent barriers, and we Huatai will have no way to survive. Besides, we engineers are constantly finding problems and solving problems, and we need engineers like you who have a groundbreaking mindset. ”

"Do a good job, Huatai Company won't treat you badly!" Qin Yifei patted Yang Jie's shoulder and said.

After a while, Qin Yifei immediately gathered the engineers of the project team and told Yang Jie's analysis, and everyone thought that this was a good way, so they began to study and arrange solutions and arrange scheduling personnel according to Yang Jie's ideas.

Yang Jie was also busy with dozens of engineers, and these engineers did not have any contemptuous attitude because he was young.
