Professor Zhang Xi and others from the Silicon Valley headquarters once again held a conference call with Lin Lanying's team in Bincheng, China, through transatlantic telephone, and they don't know how many times they have held such a conference in the past two months. The personnel of the two sides informed each other of the study and research progress, and the mail and parcels sent to China were transported by a box truck every day, which were all documents and photocopies of the original translated by the technicians themselves.

Although this kind of communication is not very convenient, it has also made the two teams gain a lot. Lin Lanying also had a good understanding of computer technology in the United States through exchanges with Professor Zhang Xi and others, which provided her with many new ideas and ideas for her scientific research work.

Professor Zhang Xi once proposed to Lin Qiangsheng that Lin Lanying lead the team to the United States to do a period of scientific research, which will be of great help to Lin Lanying and others, and the convergence of the two parties will also be more able to concentrate talents! After all, the equipment here is very advanced, equipped with the latest scientific research technology from Europe and the United States, and I don't know how many times more advanced than domestic technology. At present, the process technology they use has reached the level of 1.5 microns, and even 8 microns have not been promoted in China, and the equipment technology of Bincheng Dongxing Semiconductor has only reached the 3 micron level, and it is challenging the 1.5 micron process technology!

But such a proposal made Lin Johnson very worried, the United States is not a paradise, although the scientific research environment here is very good and open, many famous companies in the world have set up research laboratories in the United States.

After all, Lin Johnson's company has a Chinese background, and the premise of developing in the United States is that Sino-US relations are developing in a good direction, and the United States has also intended to open up many technological fields to China in the past two years.

But Lin Qiangsheng is still very cautious, and his eggs can't be put in one basket. Recently, there have been FBI surveillance vehicles around his company, and Lin Qiangsheng also speculated that there have been FBI infiltrated agents in the company to monitor him. However, he is not too worried about this, as long as he is cautious and blatant, and he pays so many taxes every year, the FBI must first consider whether he can afford to provoke the IRS and his team of barristers. As long as Lin Johnson does not ship the most advanced machinery and equipment out of the United States. The FBI can't do anything with him either.

But if Professor Lin Lanying wants to come, it will be too inappropriate. It is better not to put eggs in one basket, and from all indications, Lin Lanying, who once worked as a senior engineer in a famous semiconductor company in the United States, is still valued by Americans.

In 79, Lin Lanying once participated in a computer technology seminar organized by overseas Chinese, and an overseas Chinese mentioned to Lin Lanying after the meeting that the United States also welcomed her back, and if Lin Lanying was willing to go, the overseas Chinese would help her arrange everything. Lin Lanying sternly refused at that time, and the matter was over. But Lin Qiangsheng is in mind, like such a scientist who has made great achievements in the field of semiconductors, Americans should be very worried about her contribution to China, Lin Qiangsheng has strengthened the security measures of the East Star headquarters and Silicon Valley headquarters, and the personal safety of scientists must be extremely important!

Although it is not certain that there are any eavesdropping and surveillance activities within the company, Lin Qiangsheng is not cautious and frightened because of this.

After two months of consulting information, engineers and technicians from China have a deep understanding of the X86 architecture of 8086 and 8088 processors, and many people have studied Intel series processors in China. Now that they have come to the United States to see such a wealth of technical information, there are also the world's most complete chip circuit drawings for analysis and learning, and they can't understand it in depth.

At the beginning of November, Lin Qiangsheng issued a plan to Zhang Xi, Dong Jiasheng and others to develop chips, named Dongxing 0.

This chip will use x86 architecture, yes, that's right, Lin Johnson's computer company will follow in the footsteps of Intel and AMD to use x86 as the processor architecture. In any case, it doesn't matter if Lin Qiangsheng is bold and reckless, or a newborn calf. He is trying to use this architecture to earn a place between Intel and AMD.

Now the x86 architecture has only been born for two years, and it is not as unbeatable as the future generations! AMD has been granted a patent for the x86 architecture. Mr. Lin's negotiators are also negotiating with Intel about patent transfer, and licensing is acceptable. If Intel doesn't authorize or transfer, he can still go to AMD, anyway, Intel doesn't plan to stick to the x86 architecture, just see if the price is appropriate.

No matter what, Lin Qiangsheng has to go down this road. He abandoned the curve-by-curve tactic, unlike many companies that choose to avoid direct competition with Intel and choose to streamline their architectures.

Lin Qiangsheng wants to directly compete with large manufacturers in the chip market, and is also optimistic about the rich scalability and flexibility of the X86 architecture. Even if Intel is its creator, with the subsequent development of x86 technology, latecomers like Lin Johnson & Johnson can change the direction of x86 development. This is an example from AMD. Lin Johnson is also walking its path.

Such as x86-64 and EM64T struggle. In 2003, AMD introduced the industry's first 64-bit processor, the Athlon64, and also brought x86-64, a 64-bit extended superset of the x86 instruction set, with backward compatibility. At that time, Intel was also promoting 64-bit technology, but its IA64 architecture was not x86 compatible, and was only used on server processors Itanium. In order to compete with AMD, Intel also launched its own 64-bit version of x86 in 2004, also known as EM64T.

AMD and Intel blamed each other for this, but in any case, at least the development and popularization of 64-bit technology was promoted, and x86 technology continued to be carried forward. David Patterson, a professor of computer science at the University of California, Berkeley and one of the inventors of RISC, said: "This proves that the flexibility of the x86 instruction set can be used against Intel, so even if Intel dominates the market, other companies can still change the direction of x86." ”

In other words, even though Intel has a huge advantage over x86, it is not alone. And Lin Johnson's choice of x86 does not mean that he wants to give up the RISC streamlined architecture.

The x86 architecture does have a great development advantage, and the reason why Intel chips have completely lost in the mobile market has given the ARM architecture a development opportunity is because of Intel's decision-making mistakes when the first smartphone appeared, and this fatal mistake made Intel give up the mobile phone market. But when the second smartphone revolution came, Intel entered decisively, not only began to enter the mobile market in a big way, but also united with a number of terminal manufacturers to prepare for a counterattack in the mobile field.

From the perspective of later developments, since most of the smartphones ran relatively simple operating systems in the first smartphone revolution, mobile phone manufacturers and system companies chose ARM-based processors to match the smartphones at that time.

However, although the processor chip of the ARM architecture can perfectly cope with the early operating systems such as Symbian and WM, when IOS and Android came out, it is difficult for a single chip of the ARM architecture to control this complex operating system. However, with the continuous upgrade and improvement of the mobile platform operating system (IOS, Android), the disadvantages of the ARM architecture are exposed, and the number of cores and capabilities must be continuously upgraded to cope with more complex system upgrades.

On the contrary, the X86 architecture relies on Intel's accumulated experience and technology in the PC market, so that it can show strong performance in the case of single core and dual core, and can compete with the quad-core processor of the ARM architecture. The reason why there are few x86 architecture smartphones on the market is only caused by market inertia. Although x86 consumes more power than ARM, with the upgrading of the process and the improvement of the architecture, the power consumption will also be greatly reduced, and the two architectures may also be equally divided in the future smartphone market.

But that will only happen 20 years later, when smartphones are launched, and now it is completely x86, and making products suitable for the market is what Lin Qiangsheng needs to do now! It can only be said that ARM appeared when it should appear, when to develop what technology, Lin Johnson & Johnson has its own plan.

Two professors, Zhang Xi and Dong Jiasheng, lead a R&D team of more than 40 people to conduct R&D at the Silicon Valley headquarters, and there are more than a dozen American researchers employed by Lin Johnson & Johnson in the United States. Many of them have worked in well-known semiconductor companies, so they can lead Zhang Xi's team to carry out American-style scientific research projects, so that domestic technicians who do not understand the American way of working can familiarize themselves with the environment here as soon as possible.

In Bincheng, there are also scientific researchers led by experts such as Lin Lanying who are doing research, and there are quite a lot of domestic R&D personnel. At present, Dongxing Semiconductor has a total of more than 20 cooperative research institutes and laboratories and is still increasing, and there are 65 technical experts with associate researcher level or above who are engaged in scientific research with Dongxing Semiconductor.

Electronic computer technology is a major category, and optical wafer production includes many large projects such as mining, fine processing, manufacturing, and cutting. China has been lagging behind foreign countries in how to fine process silica powder, and high-purity electronic-grade raw materials are imported from Europe, America and Japan.

In addition, Professor Lin Lanying is also leading the team to study the technical upgrading and transformation of 3-micron process technology, so that Dongxing Semiconductor can overcome the difficulties of 3-micron technology to reach 1.5-micron process technology, and she is also responsible for the development of a new single-crystal furnace to increase the wafer diameter to 75mm and break through 100mm!
