When all the students in the classroom heard Li Yunyan, they all looked at each other in disbelief, as if they couldn't believe it.

They took out their mobile phones again and looked at them carefully.

Tian Jibai looked at Li Yun with a relieved face, when he met such a good student, any professor would be silently happy and informative in his heart.

"How do you know you're telling the truth? Wouldn't the chips in all electronic devices have this kind of listening function? Why don't these companies file when making and applying for patents? Gu Dexuan insisted on his opinion and asked with some disbelief.

Li Yun looked at Gu Dexuan, and then said: "The application of chips belongs to the core technology of a product, some companies will appeal with the adjudication body for their core components when applying for patents, in fact, this is also a loophole, the adjudication body is given certain privileges to the company's core technology, which includes the part of chip monitoring, Gu Dexuan is worried about what I am worried about, which is also what those of us who study applied science have to find a way to solve, if someone solves it, Then there is no point in our existence. ”

Gu Dexuan listened to what Li Yun said, his eyes were still full of disbelief, and then said: "Since you said that all chips have this kind of memory particles that can be monitored, can Li Yun ask for advice?" ”

Li Yun listened to Gu Dexuan's words, it seemed that he was going to challenge himself, Li Yun smiled faintly, this is not an enemy, it is completely an academic exchange between classmates.

Tian Jibai looked at Gu Dexuan, the eighty-one students who have taught applied science have been more than three years, and they know more or less about each student, Tian Jibai stood on the edge of the podium, watching the students who were doing it to make a good progress on what they had learned, and secretly rejoiced in his heart.

In front of all academics, there is no progress without controversy, and for science for practical applications, there is no perfection without problems, and there is no disagreement, which means that there is no more innovation.

"Gu Dexuan, don't hesitate to teach." Li Yun said with a gentleman's courtesy.

Gu Dexuan breathed a sigh of relief, and then said, "Let's take the mobile phone CPU chip you just said!" The processor used in the Daoxiang mobile phone is D9, please ask Li Yun, D9 is based on D8 from the original single core to multi-core, and at the same time enhance the memory management unit, so can Li Yun tell us where the internal monitoring of D9 is? ”

Gu Dexuan asked this, but it made all the students sweat for Li Yun.

After all, even if you are a powerful electronic engineer, it is impossible to know the internal structure of all CPU chips, after all, in every company's design and research, these are core secrets, and it is impossible for others to know.

Gu Dexuan's words are undoubtedly a slap in the face to Li Yun, even if Li Yun is powerful, it is impossible to know so much, and it is even more impossible to understand the structure of the D9 chip.

At this time, when Tian Jibai was listening to Gu Dexuan's question, his deep eyes were staring at Li Yun, but Li Yun seemed calm.

Li Yun didn't squeak for a while, and all the students looked at Li Yun, thinking that Li Yun must have been stumped this time, not because Li Yun was not capable, but because not everyone knew all the core processor chips of various companies, even if they couldn't answer, it was reasonable.

At this time, Tian Jibai looked at Li Yun and thought that Li Yun might really not know, but being able to say that the processor chip was embedded with listening memory particles was also a very accomplished idea, but not everyone might believe it, and it was just a general panic.

Just when everyone thought that Li Yun had encountered a bottleneck and was speechless, Tian Jibai was just about to play a round for Li Yun to relieve the siege, Li Yun replied calmly.

"Daoxiang D9 scalable multi-core processor and single-core processor support 16, 32 or 64KB4 road associated L1 and L2 cache configuration, using out-of-order guessing to execute 8 stages of pipeline processor, these configurations do not see any flaws, the problem is that the architecture of D9 is too perfect, and behind the perfection is a big pit, there is no problem with its own memory particles, and there is no so-called monitoring, this is the most clever revision of D9, Because Daoxiang Technology cleverly attaches the monitoring particles to the detection and filtering position of the 8-stage pipeline processor, because it is filtering, it happens to store the monitoring particles in the CPU in the form of clutter, and it seems that Daoxiang has a great electronic structure engineer. Li Yun said leisurely, and then looked at all the students who were doing it.

When all the students heard Li Yun's answer, their eyes instantly widened, and their expressions were full of surprise.

Tian Jibai looked at Li Yun, his face was not only relieved, but also a rare affirmation.

After listening to Li Yun's superb answer, Gu Dexuan was dumbfounded, Gu Dexuan didn't know how Li Yun knew this, the fear of the unknown was the most terrifying.

"How do you know that?" Gu Dexuan's eyes were full of doubts, but there was some admiration.

After Gu Dexuan asked, Tian Jibai also looked at Li Yun with a puzzled expression, and Tian Jibai also wanted to know.

Li Yun secretly laughed for a while, and then Li Yun looked at Bi Sheng beside him, and Bi Sheng looked at Li Yun with a smug expression.

Li Yun was able to know the information about the D9 chip, completely because Bi Sheng hacked into the internal website of Daoxiang Technology, and when Li Yun was thinking about the information, Li Yun instantly remembered it in his mind.

Li Yun glanced at Gu Dexuan lightly and said: "We are studying applied science, and the front-end technology of Qin State is the focus of our attention, because we can't just stay in the theoretical stage, we are learning applied science, theory is just a means for us to put into practice, and we have to learn a lot of things." ”

Gu Dexuan looked at Li Yun and said very preachy, with a look of shame.

Gu Dexuan didn't say anything lonely, and the bird sat quietly in his seat, silent.

At this time, Tian Jibai had a kind smile on his face, and when he saw the students under his hands, especially Li Yun, he really felt that he had picked up a golden pimple.

Bi Sheng looked at Li Yun and smiled mischievously, and then turned off his phone.

"Well, I think everyone should have a deep understanding of electronic information, of course, thanks to Li Yun and Bi Sheng, I hope everyone can really pay attention to their actual ability, after all, just like Li Yun said, applied science is to be put into practical action." Tian Jibai said to all the students.

When the students heard Tian Jibai say this, they thought about Li Yun and Bi Sheng, and suddenly felt that although they had solid theoretical knowledge and more than enough test scores, the real practical application was really far from Li Yun and Bi Sheng.

A unique applied physics course ended in a wonderful end, everyone admired the strength of Li Yun and Bi Sheng, and also had a new understanding of themselves, the reason why applied science can become a top-notch major in ice engineering is precisely because of its important role in practical application.

The time of a class ended quickly, and the students gradually left in the discussion, and when they saw Li Yun and Bi Sheng after class, they all had admiring smiles on their faces, Ye Tianlong saw Bi Sheng's face embarrassed, and Bi Sheng was also embarrassed.

And when Gu Dexuan saw Li Yun, that kind of sincere admiration was self-evident, maybe because he was arrogant, Gu Dexuan just nodded and gestured to be friendly, and then left with the people he was familiar with.

Bi Sheng drove Li Yun and said, "Boss Yun, why didn't we leave too!" By the way, do you have anything else to do? ”

Bi Sheng looked at Li Yun slipperily, Li Yun looked at Bi Sheng's expression, and said, "Stinky boy, we have to find the right person." ”

Bi Sheng looked at Tian Jibai, and it happened that Tian Jibai walked in the direction of the two.

Li Yun hurriedly stepped forward and said respectfully: "Professor, Li Yun has something to tell you." ”

Tian Jibai looked at Li Yun with a smile and said, "It just so happens that I also have something to look for you?" ”
