Chapter 1441 Major Breakthrough
One month later, as Cheng Qingyan gradually recovered, she was able to get out of bed and exercise normally.

During the confinement period, Cheng Qingyan gained a lot of weight under the careful care of her family. This was unacceptable to her who has always loved beauty, so after confinement, she immediately invited a doctor from Guangzhou. A full-time fitness trainer started exercising in his own gym.

Cheng Qingyan is a woman with strong will and self-control. During her pregnancy, she felt extremely tormented. Now that her son has been born smoothly, a shackle in her heart has been lifted, and her whole body has regained her former vitality.

It only took one month for Cheng Qingyan to regain her former slim figure, and she has become fond of jogging now. Every day when she wakes up early and before going to bed at night, she will run for a few kilometers around the road in the villa area, and every time she When traveling, there will be many bodyguards behind him, which looks quite imposing.

The child is still breastfeeding, so Cheng Qingyan can't go back to the company to work. At most, she will go to the workshop by car to inspect it every now and then. Most of the time, his assistant will send the documents and materials in the factory to her home, and Cheng Qingyan will handle them remotely by phone and fax. company affairs.

During this period, Duan Yun and his USB R&D team made a major breakthrough, and they have developed a primary USB solution.

To develop a complete USB interface, the process is more complicated. In addition to its hardware circuit design, it also includes the software design process, mainly including interface chip firmware programming, device driver development and application software design. The firmware of the USB interface chip is its various underlying functions, which are used to realize operations such as reading and writing of the chip.The device driver is mainly used to drive the USB device so that it can be recognized after connecting to the host computer.Among them, the device driver also needs to complete the work of firmware download, so that the user can apply the designed firmware.After completing the writing of the interface chip firmware and device driver, write the user control software to control the communication process of the USB interface according to the user's needs.

In his previous life, Duan Yun systematically studied and studied the principle and basic structure of USB transmission, which allowed him to avoid many detours and at the same time be able to efficiently develop this product.

The bus standard of USB has mainly undergone three versions of upgrades: USB1.1 - supports low speed (HalfSpeed) 1.5Mbps and full speed (FullSpeed) 12Mbps; USB2.0 - supports high speed (High Speed) 480Mbps; USB3.0 - 5Gbps that supports SuperSpeed.

However, the first-generation version developed by Duan Yun has been able to achieve a low rate of 2.5 MB and a full rate of 20 MB, which is already higher than the first-generation USB transmission version. Only certain upgrades and improvements to related software and data are required. will be continuously improved.

The successful research and development of the first generation of USB can be said to be an epoch-making event. You must know that in 1, the most advanced hard disk in the world was 1989 inches with a capacity of 2.5 MB. In the early 512s, IBM will release The first 90GB 1-inch hard drive for civilian use, the growth rate of capacity can be described as changing with each passing day.

While the storage capacity of the hard disk is constantly expanding, many users find that the transmission speed of the interface in their hands is still calculated in Byte, 1 KB=1024 byte, which is almost the speed of a snail.

1 MB=1024 KB, 1 KB=1024 byte, based on the 3~3MB capacity of an MP5 song in later generations, it will take dozens of hours or even a few days for users in this era to download an MP3 song. What's more, there is no MP3 format nowadays, so the songs at that time could not be downloaded freely on the Internet, and most of them could only be played on CDs.

The successful research and development of Duan Yun’s first version of USB is definitely a milestone event in the technology world. It only needs to continue to improve the relevant software and hardware systems, then the world Internet will usher in a revolution, and companies that have mastered this technology It is enough to collect patent fees, which is enough to make a lot of money.

The USB developed by Duan Yun may not become an industry standard in the early stage, and countries such as Europe, America and Japan will not easily accept this new foreign product and technology, but as an epoch-making product, if If Duan Yun can use it on the computer products he has developed, it is very likely that it will quickly open up the international market, which will definitely impact PC manufacturers around the world and drive changes in the entire industry.

However, if Duan Yun wants to achieve this goal, he still has a lot of technical problems to be solved, including product improvement and upgrading and matching and integration. All of these require a lot of investment and cannot be completed in the short term.

The only thing Duan Yun has to do now is to quickly apply for an international patent for USB, and complete the development of USB-related hardware before the end of the year. At the same time, he must also speed up the development of MP3, and strive to enter the world Internet market after the start of 90.

In addition, it has been scheduled to hold the annual World Consumer Electronics Factory in the United States at the beginning of next year, that is, the CES conference. At that time, Duan Yun will use this exhibition to announce his USB technology products to the world for the first time.

Although Duan Yun has now made a major breakthrough in technology research and development, he also understands that if he does not have strong research and development strength, he may face a weak successor and be surpassed by other international manufacturers.

Duan Yun's R&D center is absolutely top-notch in China, and it has the support of the Shenzhen Science and Technology Industrial Park, but even so, compared with those multinational technology giants, Tianyin Group's R&D capabilities still have a huge gap. To maintain it, we must absorb more top talents.

It is precisely because of this that Duan Yun thought of hiring professional managers with high salaries to gradually establish a new international cooperation model and establish related R&D centers in Europe, America and Japan.

It's just that there is no information from Wang Shi yet, and he has to go through an intermediary to get in touch with Hu Zhengming. In the end, whether Hu Zhiming is willing to come to Shenzhen to join Tianyin Group is still unknown, so Duan Yun can only wait now.

However, what Rang Duo didn't expect was that he had to wait for more than 4 months because of some turmoil in the country. It was not until the beginning of September that Duan Yun got the news from Wang Shi that Hu Zhengming was currently participating in a competition in Hong Kong. For the forum meeting, he will arrange for the two to meet in Hong Kong to discuss cooperation matters.
