Judging from the news so far, this surging “small chip” should be an independent ISP (Image Signal Processing) chip, that is to say, the ISP packaged in the mobile phone SoC can no longer meet the needs of Xiaomi, so I set up an independent ISP myself, hoping to push the level of mobile photography to a whole new level. Now all the big Vs on the Internet are frantically raising expectations of the Xiaomi 11 Super Cup, and the camera performance is the biggest highlight. We can reasonably guess that in addition to Samsung’s world’s largest mobile phone CMOS GN2 (1/1.12 inch), Xiaomi’s independent ISP chip should also play a key role. Compared with other mobile phone manufacturers, Xiaomi has chosen a more difficult road. Once it succeeds, Xiaomi’s advantage in mobile phone imaging may not be so easy to surpass. However, the specific parameters of this chip are not yet known. Let’s look forward to the press conference on the evening of the 29th! I think this is more awesome! The battery has finally improved! It must be a lithium battery. It should be a kind of silicon oxide added to the graphite negative electrode, which can store more lithium, increase the battery density, and achieve the purpose of reducing the battery volume. Of course, it can also be larger in the same volume. Capacity battery. In addition, the addition of silicon oxide may also increase the allowable current, so “charging is faster.” In short, I am more and more looking forward to the 29th press conference~

For this question, we must first understand that the new Surging chip that Xiaomi will release on March 29 is not the next-generation processor of the previous Surging S1, but an ISP chip. The ISP chip is also the image signal processing chip, which is mainly used in taking pictures. A powerful ISP can obtain excellent computational photography capabilities. The self-developed ISP of the Apple A10 Fusion generation can perform 100 billion operations in 25ms, and one picture of the Apple A12 Bionic generation can perform 1 trillion operations. This year’s Apple A14’s ISP has inserted two A12 Tempest small cores, which can realize smart HDR 3, Dolby Vision 60-frame video shooting, and Apple ProPAW. The powerful ISP not only allows the iPhone 12 Pro to achieve a score of 128 points in DxOMark photography with three small bottom lenses, but also achieves so many functions above. However, the computational photography capability of Android has been difficult to break through due to the limitation of the processor ISP. This time Xiaomi’s self-developed new ISP is to break through the limitations of the Android processor ISP and elevate computational photography to a new level. Thus, two roads are available for Xiaomi, one road is like the upcoming Xiaomi 11 Ultra, self-developed ISP + super outsole, to achieve the ultimate photo effect. The other way is like Apple’s, the combination of self-developed ISP + small bottom, with powerful computational photography capabilities, allows mobile phones to maintain excellent photo effects, while reducing the size of the camera sensor, making mobile phones extremely thin and light. This is a new breakthrough for Xiaomi, after all, computational photography is the right route for mobile phone photography in the future.

Bob, what do I say. Look at the chips coming. On March 22, I bluntly said that the chip will be released. Everyone disagrees and finds it unrealistic. But it really came, and I can only say that my prediction is still wide. Part of why you want to send a chip is really because you need it. In addition, because everyone knows about force majeure, the market is vacant. And Xiaomi has invested heavily in the semiconductor industry in the past two years, but it has to bear fruit. High-end chips will be unfinished for a while, but certain types of chips can come first. Train the team step by step, and gradually master chip manufacturing to accumulate your own strength. Whether it is investment, cooperation with Qualcomm, or research and development by yourself. Xiaomi’s goal to make chips is not to become, they are very stable, and they should have good results! Hope that Xiaomi’s press conference can bring us more surprises!

This small chip should be an ISP chip. ISP is an image signal processor. Many Xiaomi mobile phones have 100-megapixel lenses, which look very big and scary, but the actual imaging effect may not be ideal, which is what is said to be ineffective. After all, the larger the pixel, the better the imaging, and its ISP also has a certain impact on imaging. Why do you want to build a new ISP chip, it may be that Qualcomm is not very attentive to the image, and the update is too slow to meet the needs of Xiaomi. So I developed a new chip by myself. It is always good to build an ISP chip independently, and your own products are more handy to use, and the imaging effect will be better. The best is not necessarily suitable for you, and the best for you. This time it’s a small chip, what about next time? Will there be a big chip?

As we all know, in April 19, Songguo Electronics Co., Ltd., which made Surging S1, was split and reorganized by Xiaomi. Part of the team established Nanjing Dayu Semiconductor to focus on the research and development of AIOT chips and solutions; while Songguo Electronics continued to focus on Mobile phone SOC research and development. In addition to the fact that Songguo Electronics became a directly wholly-owned subsidiary of Xiaomi in 20 years, it has been quiet except for a little news. You can’t even find its official website. Understandably, after all, the path of mobile phone SOC is too difficult, and the entire Songguo Group should still be in silence at this stage. So this time, Xiaomi’s small chip should not have much relationship with Songguo Electronics. And Big Fish Semiconductor is relatively active. First of all, Dayu has always used the surging S1 chip to be a bit unpleasant, called “waste utilization”, and a bit better, called “best use”. The image transmission module processor used in the drone solution proposed by Dayu Semiconductor It is Surging S1. At the same time, the world’s first NB-IoT dual-mode chip with built-in GPS/Beidou, U1, was released in May 19th, and it has been successfully commercialized, while another Bluetooth low-power chip U2, which was by Zhange Reuters in 2020, has not Official release and outgoing commercial information. The surging new series of chips released this time is likely to be a masterpiece of Dayu Semiconductor, and according to Reuters information, it should be a small ISP chip. Zhange’s Weibo in December last year undoubtedly proved this on the side. The chip road is obstructed and long. We already know that Xiaomi has suffered a lot of cynicism since the release of the surging S1. This time, I returned with this self-developed ISP chip again. To be honest, tears are in my eyes. Good fighters have no great achievements. From 17 years to the present, four years have passed, and four years of obscurity have finally been exchanged for today’s flat ground thunder? Don’t talk about it, just look forward to it.

Of course he was extremely excited. Thinking of the surging S1 that year, I still have a deep memory, because at the press conference at that time, I squatted under the stage, as a simple fan, looking up at Lei Jun with a group of reporters. Back then, I could see the light on Lei Jun. Unfortunately, the development of mobile phone SoC is too difficult. The biggest barrier is not the CPU or GPU performance that everyone is more concerned about, but the baseband. The patent barriers of baseband are too strong. Of course, even without patent barriers, the technical difficulty is unprecedentedly high. To develop baseband chips, two things are indispensable: one is a professional background, and the other is a long-term accumulation. As a consumer electronics company established less than ten years ago, it is impossible for Xiaomi to have a professional background and time in the communications industry to engage in communications baseband. And even with a professional background, such as Huawei, which has accumulated more than 20 years in the communications industry and has become a giant, it began to get involved in the mobile phone SoC industry. In the two or three years before the launch of the Kirin series, it could only be plugged elsewhere The experience of the purchased baseband is really not good. So if you look forward to a new mobile phone SoC, I think it is unrealistic. Of course, mobile phone SoC can’t work, you can also find another way. Xiaomi is probably also aware of this. In the first two years, it separated Dayu Technology from Songguo Technology, focusing on the research and development of IoT chips. Xiaomi is a pioneer in the IoT field. At present, there are already a large number of products that can be used as a moat, and there is also a self-developed IoT dedicated system vela. It is quite logical to have such a foundation to engage in IoT chips. At present, Dayu Technology has two chips that can be mass-produced, and it is estimated that it will be used in various AIoT products of Xiaomi in the future. Xiaomi’s chip road is considered a branch. But, is this enough? After all, Xiaomi’s current main road is a mobile phone. The chip disclosed this time is still called Surging, which shows that it is at least closely related to mobile phones. Is it SoC? As mentioned earlier, the probability is very small. So I think it should be the chip used in a certain peripheral configuration. What will it be? Display chip? ISP? Or something else? Or the chip that controls the secondary screen? Anyway, the news came too suddenly, I definitely couldn’t think of it all at once. But this does not hinder my excitement, so I am still looking forward to this new chip. Will Xiaomi give a strong slap to those who have long said that Xiaomi has no technology and only use supplier solutions?

It is estimated that there will be a lot of stockpiles for the Xiaomi 11Pro and ultra series this time. It is easy to understand that this is a big move for Xiaomi to compete for the market. After Huawei is sanctioned, a lot of markets will be vacated. If you are just a regular upgrade, then you may seize some markets, but not all. And Xiaomi’s ambition is definitely not to square the big cake with other mobile phones. It can monopolize the market. Or take up more and eat better, who wouldn’t like it? So be sure to catch other manufacturers by surprise and speechless, including this press conference, we can also see that a lot of new things appear together, is this a press conference? This is the same as the military parade. Xiaomi is using these technologies to give other opponents and consumers a notice and an ambition to occupy the market. Let’s talk about this chip. Internet rumors are related to image processing. In fact, this is also good. If you directly build a soc chip, it will be difficult and costly, and you may not be able to get it out. But if you start small, it’s easy to make it. First, you can get some benefits, and then you can accumulate some technical experience to pave the way for future soc. Isn’t this a good starting point? If the online rumors are true, then this is an extremely smart one-step strategy for Xiaomi.

One thing is emphasized again: “Independent R&D under the premise of open cooperation” is open because we started late, and the things we made ourselves are far from challenging external technological hegemony. Autonomy means that we must strive to be as upward as possible in the supply chain and have a little right to speak as much as possible. You have to eat one bite at a time. I am more concerned about the following points: which segment will Xiaomi choose as its entry point. What kind of problems can Xiaomi use this chip to solve? This chip is an alternative to the existing chip or a new category under a specific function. The subsequent iteration direction and product line coverage of this chip. To be optimistic, the hardware attributes that Xiaomi is not optimistic about by the capital market objectively give Xiaomi an excellent condition to test the water on the chip. If Xiaomi really decides to go on this path, we might as well look forward to what they can do. Looks like the future. After all, Xiaomi still has a little bit of technology. jpg

After a glance, I thought that the long-lost Surging S2 was about to appear. Judging from the news that broke out, it is most likely a self-developed ISP chip. Huawei, Apple, and Samsung all have their own ISP chips, and some of them are owned by friends, and Xiaomi can’t be absent. It’s definitely easier to be an ISP than a SOC. For small chips, Mr. Lei also said. The presence of ISP indicates that the image algorithm on the image has been formed, combined with the hardware quality of the 11 super large cup rear camera, I am afraid that it will be against the sky. This press conference is a bit scary. There are too many black technology things.
This is worthy of the title of big factory!

I think the DXO score list will be refreshed after the press conference. According to the news, the small chip released this time is an ISP, not a so-called surging chip. The big Vs on the network such as soc continue to raise expectations, and yesterday For the cameras on the hot list, Xiaomi is different from other manufacturers in sponsoring digital camera manufacturers, but instead does their own ISP. Therefore, in addition to the known configuration of the new Xiaomi machine, the camera will be the biggest selling point. I don’t know what the other bigwigs on the rankings think.

The road has to be taken step by step, and the meal has to be eaten bit by bit. What is certain is that Xiaomi’s “small chip” this time is definitely not a mobile phone SOC. More likely to be accessories or smart wearable chips. According to the current online news, Xiaomi’s chip may be an ISP chip, that is, an image signal processor, which is used to improve the camera’s capabilities of mobile phones. The picture is from the Digital Chat Station. Invaded and reviewed the Surging series. In 2017, Xiaomi released the “surging S1” chip. In fact, this chip was not developed by Xiaomi from nothing to independent research and development, but was perfected on the basis of Lianxin Technology. Moreover, in August last year, Mr. Lei confirmed on his personal Weibo that the surging series did not give up, and will meet with you again at the right time. So this time Xiaomi’s new product launch conference announced the surging series. I think it’s not that Xiaomi has made a breakthrough in the field of mobile phone SOC, but that it uses accessory chips or smart wear chips as a breakthrough to tell everyone: the surging series has not given up, Xiaomi Still have their own dreams and pursuits! In short, I believe that the future of Xiaomi Group can be expected!
