<div style="width:100%;text-align:center;">  </div><br> <span style="font-size:16px;">**R&D and design, production lithography and packaging testing are indispensable in the chip production process.**</span></br> <span style="font-size:16px;">Previously, in order to limit the development of China's semiconductor industry, the United States targeted China through the chip lithography link. It not only prohibited TSMC, Samsung and other chip OEM enterprises to produce chips for China, but also failed to find ASML in the Netherlands to sell EUV lithography machines that produce high-end chip equipment to China. Not long ago, it was not even allowed to sell to our DUV lithography machines. </span></br> <span style="font-size:16px;">**The good news of the domestic semiconductor industry chain is frequently heard. After experiencing the pain of being stuck in the neck of the chip production, the domestic semiconductor manufacturers have learned from the painful experience and started to devote themselves to the all-round development of the chip industry chain in China. They have made great breakthroughs in the research and development, production and photolithography of chips.** </span></br> <div style="width:100%;text-align:center;">  </div><br> <span style="font-size:16px;"> >In the R&D and design phase, the most critical is the chip architecture. As a bridge between hardware and software, the chip design depends on the predetermined chip architecture. In the field of chip architecture, the world has been monopolized by Intel's X86 architecture and ARM architecture, which can only be used after being authorized. </span></br> <span style="font-size:16px;">The so-called "learning from the past, the teacher of the future", after the production link was blocked, and there has been a precedent of Huawei being cut off by the ARM architecture, so domestic semiconductor enterprises also attach great importance to the domestic architecture RISC-V, such as the Chinese Academy of Sciences, Huawei, Alibaba and other well-known enterprises have jointly established the RISC-V architecture industry alliance, and actively promote the research and development and design of the domestic RISC-V architecture. It is gratifying that RISC-V architecture has become the third mainstream architecture in the world under the strong promotion of Chinese enterprises.</span></br> <div style="width:100%;text-align:center;">  </div><br> <span style="font-size:16px;">**Performance comparison of X86, ARM and RISC-V** </span></br> <span style="font-size:16px;">As the earliest mainstream architecture, X86 and ARM have different main application fields. X86 is widely used in server, CPU and other chip design fields due to its high performance and high power consumption, while its power consumption and performance are relatively low. ARM is widely used in mobile chip design fields such as mobile phones and tablets. The previous two architectures have led the global market.</span></br> <span style="font-size:16px;">Compared with X86 and ARM, the biggest advantage of RISC-V architecture is that it is completely open source without licensing restrictions, and has low cost and lower power consumption.</span></br> <div style="width:100%;text-align:center;">  </div><br> <span style="font-size:16px;">Academician Ni Guangnan of China has said more than once that the RISC-V architecture is an opportunity to get rid of the bottleneck in chip research and development. We should seize this opportunity and take the initiative in chip architecture. According to relevant data, at present, the number of chips produced by the RISC-V architecture in the world has reached 10 billion, more than half of which are from Chinese enterprises, and even among the 19 senior members of the RISC-V architecture, 12 of which are from China. Therefore, China plays an important role in the development of the RISC-V architecture. </span></br> <div style="width:100%;text-align:center;">  </div><br> <span style="font-size:16px;">To some extent, it is not too much that the RISC-V architecture is the leading research and development in China, because Chinese enterprises such as Alibaba, the Chinese Academy of Sciences and Huawei have long made efforts on the RISC-V architecture, and Alibaba launched the world's first high-performance chip platform; And such as Tencent and Huawei. Purple Light and other enterprises have successively released a number of chips based on RISC-V architecture.</span></br> <div style="width:100%;text-align:center;">  </div><br> <span style="font-size:16px;">Previously, British media reported that, with the rapid advancement of RISC-V architecture, China has successfully bypassed the restrictions of ARM on RISC-V architecture. In the semiconductor industry chain, China has slowly grasped more initiative, and the side effects of suppressing China's semiconductor industry have been revealed. With the passage of time, China will fully realize the autonomy of the semiconductor industry, It also ushered in a historic opportunity for the development of semiconductors in China.</span></br> <span style="font-size:16px;"> This article is selected from:科技蝈蝈 2022-12-08</span>
