For a long time, chip has been one of the important fields of "controlled by others" in China's development. However, now, "China core" has risen strongly. Pingtouge, a semiconductor company under Alibaba, released its self-developed cloud chip Yitian 710. The chip is the most powerful arm server chip in the industry, with performance exceeding the industry benchmark by 20% and energy efficiency ratio increased by more than 50%. Yitian 710 is an important step for Alibaba cloud to promote the "one cloud multi-core" strategy. It is also Alibaba's first CPU chip born for the cloud. Applications will be deployed in Alibaba cloud's data center. What are the considerations for Ali's launch of infrastructure level products for its own use? The answer is to update the computing architecture. A new computing architecture with cloud as the core is taking shape. With the further integration of cloud and network technologies, computing will further migrate to the cloud in the future, whether enterprises or individuals. This new system is evolving at three levels: first, at the infrastructure level, the cloud defines hardware, develops underlying technologies such as chips, servers and operating systems, and builds a hardware system with cloud as the core; Secondly, the core software is reconstructed based on the cloud, the open source community becomes the innovation center, and gives birth to new development methods such as low code, making the cloud easier to use; Finally, at the application layer, in the future, with the development of 5g network, computing and data will accelerate the migration to the cloud, giving birth to new species such as cloud computer, metauniverse and automatic driving. In addition, the conference also exhibited cutting-edge technologies such as carbon based chips, biochips and micro current chips. Carbon based chip is a semiconductor technology developed on carbon nanotubes, graphene and other materials, which is regarded as the direction of the next generation chip. In the same process, comparable silicon-based chips have higher performance and lower power consumption. The performance of carbon-based chips with 90 nm process is expected to be equal to that of silicon-based chips with 28 nm process. It is worth mentioning that the development of chip ecology in China is also actively promoted. For example, at the conference, Ali pingtouge announced that the full range of risc-v processors of xuantie were open source, which further narrowed the distance between risc-v technology and developers and became a new milestone of global hardware open source. In 2018, the game world in Spielberg's film virtual world was the perfect presentation of modern artists' imagination of the meta universe, which also shaped the first cognition of the concept of the meta universe by most people. Metauniverse is an all inclusive virtual world approaching the real world infinitely. Combined with AR, VR, 5g, cloud computing, AI and other technologies, it is setting off a new wave in the field of science and technology. In the exhibition area, visitors are guided by digital people through the meta universe tunnel, starting from understanding the concept, gradually understanding the application scene and imagining the trend, and then experiencing the changes brought by the meta universe for the first time through VR games, holographic images and other technologies. The concept of "meta universe" originated from the novel avalanche written by American science fiction writer Neil Stephenson. In the virtual world parallel to the real world created by hackers, everyone has his own avatar, just like a Sims, to meet and communicate with his friends. In reality, with the development and maturity of artificial intelligence, virtual reality (VR), augmented reality (AR), extended reality (XR), 5g communication and the Internet of things, the digital virtual world will be deeply integrated with the real world, bring people the reconstruction of perception from "online" to "present", and give birth to updated consumption patterns and updated business formats. In the field of bionics, yunqi conference also showed the charm of science and technology. Bionic fish appeared at the cloud habitat conference, which made people mistakenly think they were in the aquarium. The as like as two peas, the real dragon is actually the same as the real dragon fish. According to the staff, this self-developed multi joint arowana imitation robot product is designed according to the swimming posture and appearance style of arowana and relying on the existing fluid simulation technology. It can swim smoothly and gracefully like a real fish, turn and avoid obstacles, so as to achieve the effect of false chaos and truth. In addition to the golden dragon fish and building block fish, other kinds of bionic fish are also displayed in the venue: sharks, carp, etc. the appearance and action of these bionic fish are not much different from ordinary fish.
