The rise of Jingjiawei lets us see the perseverance and persistence of Chinese enterprises in the face of setbacks and difficulties. With this example of breaking through adversity, there will be more enterprises in the future to continue to forge ahead and make breakthroughs as an example to help the country achieve rejuvenation and take-off in the field of technology.
Huawei successfully developed the first 100% domestic chip, which may bring a certain challenge to TSMC. Huawei's development momentum is strong, especially in the face of US policy restrictions, the company must explore new development paths to maintain market competitiveness. This progress of Huawei has significantly promoted our country's science and technologyThe industry has moved forward and made remarkable achievements in the market.
As the saying goes, the beginning is the hardest. Only by successfully achieving a huge breakthrough from 0 to 1 can we lay the foundation for future evolution and development, especially for the domestic semiconductor chip industry with the highest technical blockade and difficulty, it is more difficult to achieve this step.China's chip research made a big breakthrough a while ago, SMIC is said to use the flow film exposure technology to reach 7 nm accuracy, there is no redundant information, there is no saying that the accuracy of 7 nm, we can get some from such a brief informationUseful information.
At present, Huawei, Haiguang and other manufacturers meet the requirements of information technology application innovation to varying degrees, and also have their own advantages in the field and computing scenarios. Taking Longson, Haiguang, Mega core and other six domestic CPU as an example, on the basis of the introduction of technology, the domestic chip has successfully achieved a breakthrough from 0 to 1, and the focus of the next stage is to continue to develop and upgrade iterations.
In addition to Huawei, semiconductor industry manufacturers such as SMIC have also launched talent plans, higher treatment, recruitment. Ren Zhengfei knows: talent retention is the first element of the development of chips. bushThe chip for sending, modulating and demodulation. But as for whether a certain function is in a certain chip, it is not necessarily the matter. Some mobile phone cpu, integrated application processor, baseband processor, gps and so on.
2, feature phones generally contain only baseband chipsets, that is, the so-called BP. Smart phones, on the other hand, contain AP and BP. The AP, the Application Processor, is responsible for the execution of most applications. And BP, Baseband Processor, also known as communicationThe CP (Communication Processor) is responsible for the execution of all communication software. 3, function: baseband chip is responsible for basic digital signal processing tasks, including modulation and demodulation, encoding and decoding, signal processing and data processing. It is mainly responsible for processing low frequency or baseband signals and converting them into higher frequency RF signals. The RF chip is responsible for handling the wireless transmission, amplification, adjustment and demodulation of high-frequency RF signals, as well as receiving and transmitting RF related parameters.
4, one is necessary, is to connect the communication transceiver chip (transceiver) and the antenna must pass through; Its performance directly determines the communication mode that mobile terminals can support, as well as the received signal strength, call stability, transmission power and other important performance indicators, which directly affect the end user experience.
The RF chip belongs to a kind of analog chip (CPU, GPU, etc., belong to the digital chip), known as the pearl in the crown of the analog chip, it can be seen that the research and development is indeed difficult, but the difficulty is not as large as the CPU and GPUJanuary 14 news. Domestic technology giant Fuman Micro officially announced on January 11, 2022: the company's self-developed 5G RF front-end chip entered the mass production stage, and the domestic 5G RF chip officially landed. Compared with GPU, CPU; 5G RF module chips are less difficult to develop. However, because of the many parts of the RF chip module, it is still difficult to achieve self-sufficiency of the RF chip module.
G chip can not be built, because of technical difficulties and market monopoly.
Because the design of RF chips is extremely difficult, many overseas giants have patents for more than ten yearsAccumulation, ordinary enterprises simply can not compete with it. With the continuous expansion of the Chinese market, many excellent enterprises have also gathered in the field of RF chips. Especially with the surge of the chip wave this year, many RF companies have received the latest financing, and some excellent RF companies have raised more than hundreds of millions of yuan in financing. These chips are used in mobile phones to receive and send data, but 80% of these chips are owned by the United States and Japan. So China can't develop this technology? Rf chips require in-depth research in terms of device architecture, manpower, patents, etc., especially in terms of patentsIt is still quite difficult for the country. However, despite the difficulties, China has never given up its research on this technology.
