1, domestic chip level can only achieve 90 nm. From the perspective of chip manufacturing, equipment and materials such as lithography machines, etchers, wafers, and photoresist account for a large proportion. Among the lithographic machine equipment, the current Shanghai Microelectronics is 90 nm. High-end KrF and ArF photoresist are almost dependent on imports, of which ArF photoresist is almost zero domestic.
2, China's chip manufacturing processAt present, the manufacturing process level of China's chips has reached 14 nm, which can meet the needs of most application scenarios. In the future, the manufacturing process of Chinese chips will be further improved, and it is expected that by 2025, the manufacturing process of Chinese chips will reach 7 nanometers.
3, China's domestic chip can reach 90 nm. Domestic chip level can only achieve 90 nanometers. From the perspective of chip manufacturing, equipment and materials such as lithography machines, etchers, wafers, and photoresist account for a large proportion. Among the lithographic machine equipment, the current Shanghai Microelectronics is 90 nm.
4, and the general industrial gradeThe chip using 28nm and above process is sufficient, such as TV, air conditioning, automobiles, high-speed rail, rockets, satellites, industrial robots, elevators, medical equipment, smart bracelets, drones and so on. Compared with 5nm, 7nm this advanced process of the chip, in fact, 28nm chip is the mainstream.
5, speaking of domestic CPU, have to say Huawei Kirin and millet pine cone. At present, only Huawei Hisilicon Kirin 960 chip has been commercialized, or 16nm process. The Kirin 960 processor uses a 16nm process, and although the overall performance is good, its GPU is still a weak areaEnd and chip R & D and manufacturing capabilities of mobile phone manufacturers.
3, the surging S1 processor uses 28nm HPC process, 64-bit octet core architecture (4x2GHz A53 4x4GHz A53), can achieve performance and function balance.
4, yes, on February 28, 2017, Millet officially launched the first pine cone processor developed from the surging S1, the processor is positioned in the high-end, the balance between performance and power consumption. The Xiaomi 5C equipped with the processor was also released, and Xiaomi also released a cost-effective Redmi 4X.
1, good compatibility: the system can be adapted to a variety of millet devices, with good compatibility. Disadvantages: Update frequency: Some users reflect that the update frequency of the Xiaomi surging system is low, and some known problems cannot be repaired in time. 2, according to tests, the surging s1 can reach about 220,000 points on the Antutu run, while the Snapdragon 855 can easily break through 350,000 points. However, in actual use, such a numerical gap will not be felt. <3, First of all, the paper system in the stability of excellent performance. Compared with MIUI, the paper system pays more attention to the stability and reliability of the system, through deep optimization and rigorous testing, to ensure that the functions of the system can operate normally under various circumstances, reducing the possibility of crashes and delays.
4, Millet officially released its self-developed SoC chip - Surging S1 today. Since then, Xiaomi has become the world's fourth mobile phone manufacturer with terminal and chip R&D and manufacturing capabilities after Samsung, Apple and Huawei.
5, overall, little MisoneAt present, the surging S1 is mainly a slight disadvantage in terms of architecture and baseband, and other aspects are not disadvantageous compared to Kirin 655 and Snapdragon 625. In terms of comprehensive performance, the surging S1 small super Kirin 655 is basically equivalent to the Snapdragon 625.
6, compared with the Snapdragon 835, the performance of the surging S1 is slightly insufficient, but its power consumption control is very good, which can save power while ensuring high performance. The Paper S1 is currently mainly used in smart home, smart wear, car networking and other fields.
Xiaomi released a self-developed surging p1 chip, which is equipped with a mobile phone to improve the charging efficiency of the mobile phone, while reducing the weight of the mobile phone, improving XiaomiThe competitiveness of mobile devices helps a lot.
The surging P1 chip developed by millet and the South core SC8571 are completely different in topology, and are two charging chips with different designs, different functions and different positioning. To put it simply, the surging P1 is independently developed and designed by Xiaomi, and the South core is responsible for OEM.
Obviously, Huawei's experience has also made other manufacturers realize the importance of self-developed chips. Xiaomi released a "surging S1" mobile phone processor as early as 2017, but it has since gone nowhere. With Lei Jun personally promised the "millet chip research and development.Never stopped ", and now Xiaomi has announced the launch of self-developed chips again after four years.1, the surging S1 chip as the initial product of the pine cone processor, the performance effect barely reached the pass line, the surging S1 chip is equipped with Mi 5C fever is serious, the use experience is not good.
2, personal reasons: the creator suspends the update for personal reasons, emergencies in life, health problems, family factors, etc. It will make the creator temporarily unable to concentrate on creation, resulting in carbonization looseThe update of the fruit is suspended.
3, TEE architecture, hardware and software combination, to provide chip-level security protection. From the point of view of parameters, the performance of this U is similar to that of the Snapdragon 625. From Lei Jun's series of introductions, the biggest point is that baseband can be upgraded. Millet pine cone chip processor security is high, can effectively prevent information leakage and network fraud.
4, the network is not enabled, resulting in failure to check updates [in Settings - Wireless network - Enable network can be]. System network problem [Restore network Settings] or directly on the computer to update.
Compared with the Snapdragon 835, the performance of the surging S1 is slightly insufficient, but its power consumption is very good, which can save power while ensuring high performance. The Paper S1 is currently mainly used in smart home, smart wear, car networking and other fields.
Advantages: Extended battery life: Through intelligent scheduling and optimization algorithms, the surging system can reduce the excessive charge and discharge of the battery, thereby extending the service life of the battery. Improved battery performance: The system monitors the application's power consumption in real timeThe situation is optimized accordingly, so that the battery life performance of the equipment is effectively improved.
According to tests, the surging s1 can reach about 220,000 points on the Antutu run, while the Snapdragon 855 can easily break through 350,000 points. However, in actual use, such a numerical gap will not be felt.
