In addition to reducing the performance of Android system, the United States will also restrict the production of domestic chips from the technical roots of mask aligner, because the domestic 7nm Euv mask aligner has not seen any news about technological breakthroughs or information about the mass production of domestic 7nm soc chips.
Taking the experience of Huawei 202 1 new products as an example, the mobile phone business is really difficult to do, because the United States now has very strict control over the semiconductor industry related to the chip field, including chip architecture, chip design and chip production.
Huawei wants to use the new HiSilicon Kirin chip, and the United States began to restrict it through the core technology patent of mask aligner.
It is not only Huawei that has been hit hard, but also TSMC in Taiwan Province Province, China, which can contract to produce HiSilicon Kirin chips. It is not only forced to move its factory to the United States, but also faces the risk of handing over the core data of its customers to the United States.
Haisi Kirin processor For Haisi, they are mainly responsible for the chip integration design of electronic products such as mobile phones and computers.
The design of the chip needs to be designed, simulated and tested by professional EDA tools. Most of these advanced EDA tools come from abroad, and the United States now strictly authorizes and controls their licenses. We can only choose imitation EDA tools with weak self-research function in China to replace them.
The HiSilicon Kirin processor has always adopted the V8 architecture of ARM. Although this version of the architecture is authorized by ARM for permanent use, it is limited to the instruction set of its architecture, and the gpu and other units in the architecture are constantly changing.
Moreover, some chip research and development companies in the United States are constantly spending huge sums of money to snap up the new chip architecture developed by ARM, which makes other chip designers have to make a breakthrough in the original chip architecture.
Domestic mobile phones want to completely replace Qualcomm Xiaolong processor with domestic chips, and the current cost is very huge.
The main reason is that there are many technical links in the field of chips, which are controlled by relevant foreign institutions such as the United States. It is proved that it is very difficult for domestic chips to be used in domestic mobile phones from the aspects of chip architecture selection, chip design tools and OEM chip supply chain. The current situation of Huawei Hisilicon Kirin and Xiaomi's previous experience S 1 are enough to illustrate the difficulties faced by domestic chips. Even if domestic chips can be mass-produced and assembled into domestic mobile phones, whether mobile phone users will choose to use them is another matter.
The performance will be worse, the heat will be higher and the energy consumption will be higher, but it doesn't matter to me. I follow enough principles.
If all mobile phones are abandoned, domestic mobile phones will develop rapidly and break through the bottleneck. Domestic mobile phones will invest in research and development of chips. Whoever develops a good chip will go out of China and affect the whole world.
I don't know if it will have a great impact on mobile phones, but it will be a devastating blow to Qualcomm. It takes 800 yuan to kill the enemy.
I have never been superstitious about foreign products. China people can certainly make the best products. Believe in domestic products! Support domestic products!
If all domestic mobile phones use domestic chips, the performance of mobile phones will decline in the short term, mobile phone manufacturers will have no chips available, sales and profits will decline, and even mobile phone manufacturers will face bankruptcy; In the long run, the industrial chain of the national chip industry will develop rapidly, and so will the entire industrial chain of mobile phones and derivative industries. Mobile phone chip generally refers to SOC, including baseband, processor, coprocessor, RF, touch screen controller chip, memory, wireless IC and power management IC.
At present, there are only several domestic chips, such as Kirin, MediaTek, Zhanrui and Surge, but they are only designed and need to be manufactured by a foundry.
Let's analyze these brands:
1, MediaTek, full name of MediaTek. Inc is a global fabless semiconductor company, which is in a leading position in the market of mobile terminals, smart home applications, wireless connection technology and Internet of Things products. About1500 million terminal products with built-in MediaTek chips are listed every year in the world. MediaTek has a wide range of business, involving smart phones, personal computing devices, smart homes, smart audio, wireless connection and network technology, Internet of Things, ASIC chip customization, automotive solutions and so on.
At present, MediaTek mainly promotes the Tianji series, and the latest flagship chip is Tianji 1200, which is manufactured by TSMC. When Nokia Saipan was in full swing, MediaTek was the manufacturer that provided chips for most knockoffs.
2. Kirin, the full name of Huawei Kirin Chip, is a SoC developed and designed by Huawei Technologies Co., Ltd. Founded in 2004, it mainly makes some industry-specific chips, mainly supporting network and video applications, and has not entered the smart phone market. In 2009, Huawei launched a smart phone equipped with K3 processor to test the water, which is also the first smart phone processor in China.
Kirin's main product is Kirin 9 series. At present, the latest product is Kirin 9000, which is made by TSMC, but it is almost out of print. Because of American sanctions, we can't find a foundry to produce. At present, Huawei series has started to use Qualcomm chips and MediaTek chips.
3. Zhanrui, Ziguang Zhanrui is a leading enterprise in the integrated circuit design industry in China, and the only major chip platform provider in Chinese mainland open market that has the capability of 5G chips and successfully commercialized them. Zhanrui is one of the few enterprises in the world that have mastered technologies such as 2G/3G/4G/5G, Wi-Fi, Bluetooth, TV FM and satellite communication.
Zhanrui chips include Hubin series and Tanggula series. At present, the latest Lakeside 7520, 6nm is manufactured by TSMC, and the latest Dracula is also 6nm. Not surprisingly, it is also manufactured by TSMC. How do you say the brand Ziguang Zhanrui? If Kirin has not been sanctioned, it is estimated that the sales volume will still be half dead. Zhanrui focuses on the low-end series. The latest Dracula online says that the running score can reach 42w, but there are too few mobile phones to evaluate. The brand Zhanrui lags behind others in 2g, 3g and 4g, but it is the era with the smallest lag in the 5g era.
4. The surging is a mobile phone processor produced by Beijing Guo Song Electronics Co., Ltd., which is wholly owned by Xiaomi Company. Beijing Guo Song Electronics Co., Ltd. is a high-tech company founded on 20 16, headquartered in Beijing, mainly engaged in business cooperation with Xiaomi Technology.
At present, surging mass production is a kind of Peng S 1. According to Lei Jun, 澎湃 has encountered difficulties, and I don't know when the next processor will come out. Life and death are unknown at present.
According to the above, the only domestic mobile phone chips that can be used in China at present are MediaTek and Zhanrui. MediaTek's OEM is completed by TSMC, and Zhanrui's high-end chips are also OEM by TSMC. Due to well-known reasons, if all domestic chips are made in MediaTek, it is estimated that MediaTek will be the next enterprise under the jurisdiction of the United States, or MediaTek, like TSMC, will restrict shipments to the mainland. If all the chips of Zhanrui are used, it is estimated that the high-end chips of Zhanrui will be the same as those of Kirin now, and will not be produced. These low-end chips can be produced at most.
Therefore, if all domestic mobile phone chips are used, the performance of mobile phones will decline in the short term, and some mobile phone manufacturers will have no chips or even close down. But in the long run, the country attaches great importance to it, invests heavily, and the confidence of Chinese people will certainly give birth to some chip foundry companies and even some companies that design and manufacture chips.
I don't think there is anything wrong with using domestic chips. Just use domestic chips. It can not only promote the development of domestic chip industry, but also make people get stuck.
It is a great good thing that all domestic mobile phones give up Qualcomm chips, and domestic chips will rise rapidly. But there is a premise, and that is to drive the apple out of China!
It will take several years, otherwise it will all go bankrupt. ...
This influence is still great, but it is good for the development of domestic chip industry. Mobile phone performance can refer to Master Lu's running score data.
