Dr100 mining machine manufacturing
Dr refers to tolerant photos. That is, the coverage from high light to low light. General digital cameras have a HDR function, after opening, through some design to improve tolerance
some Fuji machines have adjustable tolerance. Parameters that can be dr100-400 or even dr800 appear. Dr100 is the standard value, that is, the high tolerance mode is not turned on.
guitar? Its electric guitar is a good brand, but they are not manufacturers of wooden guitars. They have never heard of making xylophone, and the slightly famous xylophone has never heard of Epiphone. I don't know whether it's true or not, maybe it's fake, because it's estimated that the xylophone without this brand may be genuine, but it's really not very good. Mainly depends on how much money you buy? The price corresponds to the grade. In fact, it's not necessarily a bad thing to buy fake brands. Most of the domestic brands make their own zither, while most of the foreign brands make fake ones, but their level is not necessarily poor. Maybe they used to work for foreign brands and then sell them by themselves. The quality and grade are OK, and the sex price ratio is very high. If you look at your guitar visually, it's estimated that it won't be more than a thousand

Integrating 5g modem, supporting independent and non independent networking, improving computing power and recing power consumption....
at IFA in Berlin, Germany in 2019, Yu Chengdong, CEO of Huawei's consumer business, launched a new flagship Kirin 990 series mobile phone SoC platform, including Kirin 990 and Kirin 990 5g. Yu Chengdong said: & lt; This is the most powerful 5g SOC in the world and the first and only flagship 5g mobile SOC in the instry& rdquo;
although the last generation of Kirin 980 and apple A12 chips also used 7Nm process, they did not use EUV lithography, and Kirin 9905g was the first to take the lead in 7Nm EUV process. Compared with the current mainstream DUV lithography technology, EUV can carve a smaller channel for silicon wafer and integrate more transistors on the chip
therefore, the original two chips are now integrated together, and the number of transistors has suddenly increased to 10.3 billion. The size of the Kirin 9905g chip is the same as that of the Kirin 980 with the size of the previous generation's fingernail. By contrast, the number of transistors in the previous generation of 980 was only 6.9 billion, while Apple's latest a12x integrated 10 billion transistors, but not applied to mobile devices. Kirin 9905g has the largest number and complexity of transistors in the instry
Why build in 5g baseband? For example, two people working in the same office are more efficient than working in separate offices. The same goes for cell phone chips. In terms of energy consumption, the built-in baseband can improve the chip efficiency, rece the heat of power consumption, and improve the utilization of the internal space of the mobile phone
Huawei said that in the sub-6ghz band, the peak downlink speed of Kirin 9905g reached 2.3gbps, and the peak uplink speed reached 1.25gbps. This has a high requirement for the efficiency of the chip. If we simply increase the number of transistors instead of improving the process, it can not solve the problem well
When Samsung released the exynos 980 SOC chip, it said that in the sub-6ghz band, the maximum downlink rate can reach 2.55gbps and the maximum uplink rate can reach 1.28gbps. The speed seems to be higher than that of Kirin 990, which Ai Wei said: & lt; The uplink and downlink rates given by Samsung do not meet the theoretical maximum calculated under 5g standard. Only they know how to calculate them& rdquo;the instry's first 16 core mali-g76 GPU
goes back to the core of mobile SOC, CPU and GPU. Cortex A76 and mali-g76 are still used in the CPU and GPU of Kirin 990
CPU is & lt; 2+2+4” There are 8 cores in total, and Kirin 9905g is composed of two large cores (cortex A76) [email protected] Two midnuclei (cortex-a76) [email protected] And four small nuclei [email protected] The energy efficiency is increased by 12%, 35% and 15% respectively
compared with the flagship chip of Qualcomm, the single core performance of Kirin 9905g is 10% higher and the multi-core performance is 9% higher
on GPU, Kirin 990 upgrades it to 16 cores, with 6% performance improvement and 20% energy efficiency improvement. The image processing capability of Kirin 990 is greatly increased. Yu Chengdong said frankly at the press conference: & lt; Youshang has released a PPT chip, and their GPU (mali-g77) has only five cores& rdquo;
at the same time, Kirin 990 designs intelligent cache technology for heavy-ty games. According to Huawei, this technology can effectively improve the communication efficiency among GPU, CPU and memory, thus recing the bandwidth requirement by 15% and the memory power consumption by 12%. At the scene, Huawei specially made a demonstration with chicken eating mobile game. Compared with the unicorn 990 and the Qualcomm snapdragon 855, the former consumes about 3.2w of power while maintaining a full frame of 60 frames, while the latter consumes slightly more, 3.8W
as for why we didn't use the new generation a77 CPU and G77 GPU announced by arm this year, Ai Wei replied: & lt; In fact, when Kirin 970 was released, we were already preparing the technology of Kirin 990. From the time point of view, it can not catch up with the application of arm this year. The improvement of CPU and GPU is not great. For Huawei, we are more concerned about the performance of SOC chip in terms of power consumption, which is a matter to be weighed comprehensively& rdquo;
self developed Da Vinci NPU architecture, aiming at Ai
AI performance is the highlight of Kirin 990. In the past two years, we can clearly see Huawei's strength in NPU
since last year, Huawei has transferred its application from the cloud AI chip to the mobile terminal chip Kirin 810. The first two generations of Qilin 980 and Qilin 970 adopted the Cambrian IP NPU
this time, Qilin 9905g is the first flagship SOC to adopt the Da Vinci architecture NPU, and it also adopts the architecture design of two large core npus and one micro core NPU for the first time. Kirin 990 is a macronuclear NPU + a micronucleus NPU design. Compared with other flagship SOC in the instry, Kirin 990 has a unique micronucleus design
What are the advantages of such a design? Huawei said that in the daily use of mobile phones, some applications do not have high requirements for AI computing power, and the power consumption of micronucleus is also low. Using it to process can rece the power consumption. Ai Wei gives an example. When the device is dormant, there will be low-power micronucleus work to detect changes in the outside world. When there are really large tasks, they will be handed over to the large core for processing. This kind of scene is commonly used in voice wake-up, face unlock and other tasks
the power consumption difference between the large core and the micro core is 24 times, so after using this design, the power consumption of AI can be reced to less than 5% in one day
Another practical application ofAI is valued by Huawei: real time AI recognition ability. We can see this ability on mate 20 Pro equipped with Kirin 980 before. The unique AI camera can recognize human figures in real time and color them
thanks to the new architecture mode, Kirin 9905g has higher AI computing power than 980. The former supports more than 300 operators, nearly 100 more than 980. From the video of the live demonstration, Qilin 990 can recognize and cut people and different objects in the video, thus replacing the background for the whole picture, and even deleting, enlarging and recing an object separately
no matter how good the data is,
we should also consider the implementation.
we have said so much about the improvement of many aspects of Kirin 990, and we should also let you see the implementation of the application
Huawei has led the trend of mobile phone photo taking in the past two years, but it will not lag behind the improvement of mobile phone photo taking performance
Kirin 9905g adopts self-developed ISP (image sensor processor) version 5.0, and launches BM3D (block matching and 3D filtering) professional image noise rection technology for mobile phones in the world, as well as al domain joint video noise rection technology
According to Yu Chengdong, the throughput of ISP 5.0 is increased by 15%, and the energy efficiency is increased by 15%. BM3D has been mainly used in SLR cameras before, but has never been used in mobile phones. It can effectively improve the shooting ability of mobile phones under dark light conditions. The photo noise rection ability can be improved by 30%, and the dark light scene noise is less
on the other hand, Huawei's decades of experience in the communication instry also makes them have more practical thinking about 5g applications
in the early stage of 5g business, the coverage of base station is not wide enough, which will cause weak signal, high power consumption and 5g rate instability in mobile scenarios. Huawei has optimized for these three challenges
for example, in weak signal scenarios, Kirin 9905g launched an intelligent uplink streaming design. In application scenarios such as live video and short video upload, both 5g and 4G networks are used, and the upload rate can be increased by 5.8 times
another thing worth noting is why Kirin 990 has 4G and 5g versions? Ai Wei made a special reply to this question: & lt; In China, 5g can be used on a large scale, but in many other countries and regions, 5g services may not be available& rdquo; Huawei fully considered the market demand and launched procts
judging from the overall upgrade of Kirin 990, its main driving points are AI and image. This is consistent with the characteristics of 5g. When the network carrying capacity is improved, the processing capacity of the mobile terminal side must be improved to the corresponding level, otherwise it can not work efficiently, let alone cooperate with other Internet of things devices
