After the design work is completed, according to the custom, a technical appraisal meeting needs to be held, and experts in the relevant industry are invited to review the design level of this chip.

According to Xia Lao's plan, only experts and scholars from the Institute of Computing Technology were invited to participate in the meeting.

Because it has not yet been taped out, the meeting will involve the discussion of some low-level source code and technical secrets of the chip, so it is not convenient to disclose to the public.

In the future, when the tape-out is successful and the patent is applied, a larger technical appraisal meeting will be held at that time, mainly to test the product performance to see if the design goal is achieved.

In summer, the sun is shining in the northern capital.

Hu Yiting was full of ambition with the sword of Yitian in his hand, and together with the six graduate students under Xia Lao, he walked into the conference hall of the Institute of Computing Technology of the Chinese Academy of Sciences as a research and development team.

In the hall, the conference tables are surrounded by a rectangular frame, in the center of the frame are a row of green plantains, dripping Guanyin and other leaf-viewing plants, the conference table is covered with a sky blue tablecloth, and every sofa chair behind the table is covered with a white cloth cover.

With the arrival of the participating experts one by one, Hu Yiting felt that the situation was not right, and began to frown slightly.

"Cao Yunuan, go out and ask Xia Lao, how can there be foreigners here?"

"Wu Shihuan, don't rush to send information first, wait and see. ”

Hu Yiting looked at the four guests who looked like foreigners who had entered the venue early, and guessed in his heart what their origins were.

The two foreigners who came in front of them were easily recognizable, one with black hair, deep-set eyes, a pair of tortoiseshell-rimmed glasses, and a color-striped T-shirt. The other is blonde and blue-eyed, still in a straight suit in the summer. They also had interpreters with them.

The other two Hu Yiting didn't know they were foreigners, but one of them spoke to the translator next to him in Japanese, which made Hu Yiting wary.

Hu Yiting analyzed in his heart that these two groups of people are not together, otherwise according to common sense, a team would not hire two translators.

After a while, Cao Yunuan walked into the conference room quickly, her steps were a little hurried, and the braids on her back were also flicked upside down.

She ran to Hu Yiting's side and whispered to all the R&D team members with a panicked face: "I saw that Xia Lao and Director Liu quarreled, Xia Lao lost his temper and disciplined Liu vigorously. ”

"What's going on?" asked Hu Yiting.

Liu probably wanted to put a satellite, and invited experts from the United States and Japan to participate in the evaluation, but Xia Lao did not agree with foreign experts to participate in the technical appraisal and was losing his temper. ”

The members of the R&D team looked at each other when they heard this, and the gods fought, and they, the assistant researchers and graduate students, could not intervene.

Hu Yiting sighed slightly and then decisively ordered: "Let's reorganize the materials and remove all the content about the source code, as well as all the discussions involving patents, including the design concept of the overall framework." ”

During this period of time, everyone has developed the habit of only Hu Yiting looking at the horse, and when they heard this, they immediately understood Hu Yiting's worries, and began to reorganize the technical materials that were originally intended to be sent to experts for discussion.

Wu Shihuan said in embarrassment: "Hu Yiting, so there is not much information left, starting from the fourth page to the twenty-fifth page, all of them have to be removed?"

Hu Yiting said in a resolute tone: "Withdraw, don't say that we haven't won the patent yet, even if we win the patent in the future, we can't disclose the source code to foreigners, they have the ability, so they will spend their own money to engage in reverse engineering." ”

You must know that it is very difficult to crack the encrypted underlying source code of such a complex design chip, and often a high-level technical team can only guess three or four percent even after a year and a half. If it is to be completely cracked, it will be possible to achieve it in a short period of time unless it uses the power of the state and spends a lot of money.

The user manuals provided by the chip design team to software developers are generally functional instructions and some specific implementation schemes, and the source code is rarely published, and even if there is a need to publish, it will take several years later, and it will be published in batches with reservations.

Because Mr. Xia assured him in advance that the experts attending the meeting were all important engineers and experts and scholars within the Institute of Computing, he agreed to conduct internal technical exchanges and discussions on part of the source code at the meeting.

If he knew in advance that there were foreigners participating, Hu Yiting would not want to hold this appraisal meeting at all, so it would be better to tape out directly to save trouble.

After a while, Xia Lao walked into the conference room quickly with obvious displeasure, walked straight to Hu Yiting's side and ordered in his ear: "Today's appraisal will be attended by foreign experts, don't send written materials, you go up and talk casually, delay the time, and the meeting will be dismissed in an hour!"

Hu Yiting nodded, looked at the main seat of the conference table, and saw Director Liu sitting there with an embarrassed face, holding a teacup and blowing non-stop, looking a little helpless.

In these years, in various research institutes of the Chinese Academy of Sciences, academicians are like national treasures, and their authority is far greater than the authority of professors in universities, not to mention the founder of the industry with high moral prestige like Xia Lao.

The director is generally responsible for personnel arrangement, resource management, and logistics support, and generally does not have much say in technology.

Hu Yiting saw that Liu Chengzhi, chairman of the famous Changxiang Group, was deflated, and only smiled slightly, and said in his heart that your old man was also looking for himself, and he was in a hurry to release the satellite without saying hello in advance, and it seemed that he was still too young and inexperienced.

Before the appraisal meeting began, Wu Shihuan began to distribute materials.

The experts at the meeting looked at the three pieces of paper in their hands, and then looked at Hu Yiting's R&D team, the large stack of materials that were held in Cao Yunuan's arms, and then looked at the two groups of foreign experts, and suddenly felt like a mirror.

Academician Dong Yunmei snorted and said: "I said Lao Xia, you called me from the Software Research Institute and showed me these pieces of paper? ”

Dong Lao is an authority on Chinese programming languages and compilers, and his words are not so much for Xia Lao to hear, but for Xia Lao to explain.

Professor Shen Xubang said with a smile: "Now that everyone is here, let's start." As he spoke, he looked at Hu Yiting and quipped, "You girls and boys are all in a hurry, aren't you?" Come on, don't be nervous, speak slowly." ”

Shen Lao is an authority on domestic processor chips, especially good at the field of embedded CPUs, and has participated in the development of a number of arrow-borne computers.

Other experts also knew what was going on, and they all knew that they would not hear anything deep in this appraisal meeting, so they began to drink tea, chat, and casually look at the three pieces of information in front of them.

Xia Lao smiled apologetically at the experts and did not speak.

Hu Yiting also felt a little embarrassed, he had delayed so much of the old-timer's time in vain, if he didn't tell the name today, he was afraid that he would waste Xia Lao's hard work.

So he hurriedly walked on stage and began to give a general introduction to the functions of this chip.

As Hu Yiting's explanation deepened, the experts had already put aside the three pieces of paper in their hands and were concentrating on what he said.

For a while, in addition to Hu Yiting's voice in the conference room, I heard two interpreters crackling in English and Japanese, explaining to the four foreigners.

The further down he goes, the more ugly Hu Yiting's face becomes, because if he wants to explain it in depth, it will involve a lot of technologies that are inconvenient to disclose, and inevitably talk about algorithms and structural characteristics.

The experts present also realized something, and their faces became a little solemn, but their curiosity drove them to hope that Hu Yiting would continue to elaborate in depth.

Hu Yiting finally couldn't help but scratch his head: "These foreign experts have come from afar, and it is also very hard, and it is really difficult to listen to the translation of these professional terms." Otherwise, I think you should go back first, and I will send you a detailed technical information and meeting minutes when you go back, and you are welcome to give us valuable opinions after studying the information. ”

Of course, it was impossible for Hu Yiting to provide any so-called detailed information and meeting minutes to foreigners, and this was purely a polite expulsion order, and all the experts present could understand it, so they all looked at the four foreign experts and their two interpreters.

Director Liu knew that he had caused this trouble, so he quickly got up and said: "Hu Yiting, what you said is also that the technical representatives of the United States Imperial Alliance Company and the Japanese Fujitsu Company came to Changxiang Group to discuss product cooperation this time.

Next, on behalf of Changxiang Group, I will take you to visit the computer production workshop of our group, and then take you to visit the places of interest in Beijing. ”

After Liu Suo's words were translated, he didn't expect the two groups of foreigners to shake their heads.

The tortoiseshell glasses with black hair and deep eye sockets from the American Imperial League Company said: "It's okay, we are very happy to come to China to help you improve your technical level, and if we can give you good advice, we will not be stingy." ”

After speaking, he said to Hu Yiting: "Mr. Hu, you are very young, very talented, very good! But I think you are not proficient enough in algorithms, you should talk more about the algorithm structure and logic framework of your chip, our Dimeng company is the world's top graphics card supplier, we are the world's first-class in image algorithms, I as the R&D manager of Dimeng, can provide you with a lot of important technical references." ”

With Hu Yiting's English level, he immediately understood it without a translator.

As soon as the translation voice of the Imperial Alliance Company fell, a white, short and fat middle-aged man among the two experts of Fujitsu Company in Japan also spoke.

"Hello everyone, I'm Shoji Hashimoto, an engineer in the chip R&D department of Fujitsu Corporation.

As the world's first-class computer chip design manufacturer, Fujitsu has decades of advanced experience and technology accumulation in the R&D and manufacturing of various chips.

I have been to China several times and have friendly feelings towards China, and today I would like to express my opinion in a Chinese sentence, that is, the head of the donkey is not the same as the horse's mouth.

What Mr. Hu just said, I can judge with certainty that your R&D direction is wrong!"

As soon as the interpreter finished his words, the faces of the experts at the meeting changed.

Shoji Hashimoto continued: "First of all, I think Mr. Hu's idea itself is problematic, there are already a variety of decompression chips on the market, and the professional decompression card equipped with the decompression chip can completely decompress videos and images, so it can be said that your product has lagged behind from the beginning of the design.

And as far as I know, in the field of compression and decompression of graphic images, basically all feasible solutions have been registered patents, and you China currently does not have the ability to design an independent intellectual property core. Since there is no structural support for the application, your algorithm is meaningless. Especially your coprocessor chip, it still needs to rely on the CPU to perform a lot of calculations, which is obviously a very backward structure.

Finally, I will say algorithms, to be honest, I don't think you Chinese currently have the ability to come up with a set of streamlined and effective algorithms to improve the processing efficiency of graphics images. If you don't believe me, you can explain the source code of your algorithm in detail, I believe that our Fujitsu algorithm is much faster than yours, and the execution code of the corresponding instructions is much simpler. ”
