Vivo launches new achievements of self-developed chip V 1+. This time, the second-generation self-developed chip V 1+ and the second-generation dual-core standard were launched, which not only evolved again at the image level, but also extended the chip function to the fields of performance and display. Vivo launches new achievements of self-developed chip V 1+.
Vivo launches self-developed chip V 1+ new achievement1On April 20th, vivo held a technical communication meeting to launch its second self-developed chip V 1+. This chip is not only a professional image chip, but also a display performance chip. It is the first multifunctional self-developed chip developed by domestic manufacturers. The first model of this chip will be vivo's X80 series flagship new machine.
Over the past year or so, many domestic manufacturers have launched self-developed chips, but all of them are single-scene functional chips, not the core SoC chips in mobile phones. However, insiders pointed out that for most domestic mobile phone manufacturers, it is a more reasonable research and development path to start with functional chips, gradually master chip design capabilities, and then enter the most difficult SoC chip. V 1+ chips move from single function to multi-function, which may be the embodiment of this R&D path.
According to the information released at this conference, the X80 series, the next flagship model of vivo, will be equipped with V 1+ chips. Hu Baishan, executive vice president of vivo, introduced that vivo and MTK's latest flagship chip, Tianji 9000, were jointly developed, so at least some models of X80 series should be equipped with Tianji 9000 chip.
At the same time, Hu Baishan also stressed that vivo is the only mobile terminal manufacturer in the industry to realize the compatibility of self-developed image chips with multiple flagship platforms. In other words, the chip V 1+ will also appear on the new vivo machine equipped with Qualcomm Snapdragon flagship chip in the future.
Vivo launches self-developed chip V 1+ New Achievements On April 20th, at the "Vivo Dual-Core Imaging Technology Communication Meeting", vivo launched a number of new achievements independently developed, covering chips, images and performance. Among them, the self-developed chip V 1+ is the core of this communication meeting and the new weapon of vivo.
Hu Baishan, executive vice president of vivo, said at the communication meeting that the self-developed chip V 1+ is not only a professional image chip, but also a display performance chip. The comprehensive improvement of compatibility and functionality has brought the second generation dual-core flagship new standard. This self-developed chip will also be applied to the upcoming vivo X80 series.
Same chip, stronger performance, better experience.
The performance of the same chip is different from different manufacturers, and the adjustment ability of the chip is involved behind it. Take Tianji 9000 as an example. Since its birth, Tianji 9000 has been well received and won a good reputation for its excellent performance and energy efficiency.
Vivo cooperated deeply with MediaTek, * * * invested in a development team of more than 300 people, and spent nearly a year in software and hardware collaborative development. The chip V 1+ was thoroughly communicated and optimized with Tianji 9000, which can also better release the performance of Tianji 9000. Simply speaking, it is also the secret 9000, and the experience is better under the adjustment and optimization of vivo.
Thoroughly adjust V 1+ chip and cat 9000.
So, what has been done behind vivo? In order to improve the energy efficiency ratio of Tianji 9000, vivo adjusted the CPU resource allocation strategy by algorithm, which reduced the machine fever, solved the problem of probability fluctuation of performance, and effectively improved the energy efficiency ratio of Tianji 9000 platform. According to the data revealed by vivo, the battery life can be extended by 10% in heavy game scenes. This is a big promotion.
In order to improve the user's computer experience, vivo established a "user scene fluency model", which improved the overall animation fluency in the load scene by 50% by optimizing the calculation power distribution. By designing a high concurrent computing mode, the problem of CPU resource preemption and idleness is solved, and the application can be started continuously faster ... Generally speaking, a good balance is achieved between high performance and low power consumption.
The combination of two cores, a "core" has two purposes.
This time, the second-generation self-developed chip V 1+ and the second-generation dual-core standard were launched, which not only evolved again at the image level, but also extended the chip functions to the fields of performance and display, expanded the support for games and video visual experiences, and realized dual use of one core. Specifically, V 1+ encapsulates three algorithms: 3D real-time stereo night scene noise reduction, MEMC frame insertion and AI super-segmentation, which have three characteristics: good scheduling, high speed and high energy efficiency. The performance breakthrough of V 1+ is also reflected in the game. In the game scenario, performance and power consumption have achieved a good balance.
V 1+ dual-core image
In terms of images, the changes brought by V 1+ are obvious. It has been fine-tuned for night video. The extreme night noise reduction algorithm of V 1+ can realize motion prediction and compensation, and make the mobile phone reach the imaging level of professional night vision equipment. In this way, vivo extends the black-light night vision function to the front and wide-angle lenses, which improves the camera and camera capabilities of the mobile phone.
V 1+ has also brought about changes in the image experience. First of all, color, the pursuit of faithful restoration of human eyes, the pursuit of Zeiss natural color, from the four dimensions of detection, shooting, processing and display, to achieve full link color management. Followed by portraits, professional portraits were obtained through technical breakthroughs before, during and after portrait shooting.
From the chip of V 1 to the chip of V 1+, vivo is constantly exploring the no-man's land of mobile phone images in its own direction, constantly surpassing itself and embarking on a brand-new road. In the upcoming vivo X80 series, we will be able to see its excellent imaging ability.
Vivo launches self-developed chip V 1+ New Achievements 3 On the afternoon of 20th, vivo held an online communication meeting on dual-core imaging technology, revealing the latest achievements of self-developed chip, image and performance. Hu Baishan, executive vice president of vivo, said that the self-developed chip V 1+ is not only a professional image chip, but also a display performance chip, and will appear in the ――X80 series, the new flagship model of vivo to be listed soon.
In order to break through the computing limitation of general computing unit on mobile phone images and performance, vivo began to promote hardware-based algorithms from 20 19, and officially launched the first self-developed image chip vivoV 1 last year.
At this communication meeting, vivo launched the second-generation self-developed chip V 1+ and the second-generation dual-core standard: it not only evolved again at the image level, but also extended the chip function to the performance and display fields, expanded the support for games and video visual experience, and realized a dual-purpose "core".
Hu Baishan, executive vice president of vivo, released the "new standard of second-generation dual-core flagship"
At the end of last year, MediaTek released the Tianji 9000 processor. As strategic technical partners, vivo and MediaTek have invested more than 300 elite development teams since last year. After 350 days of deep co-development of software and hardware, V 1+ chip and Tianji 9000 have been fully optimized. The test shows that Tianji 9000 has achieved higher energy efficiency ratio, faster response speed and stronger game experience, and the running score in Antu Rabbit Lab has exceeded 654.38+0.07 million, making it the champion of Tianji platform performance.
At this point, vivo has not only become the first terminal handset manufacturer to communicate with MediaTek's flagship platform on the self-developed video chip, but also the only mobile terminal manufacturer in the industry to realize that the self-developed video chip is compatible with multiple flagship platforms.
It is reported that the vivo self-developed chip V 1+ encapsulates three algorithms: 3D real-time stereo night scene noise reduction, MEMC frame insertion and AI super-segmentation, which has three characteristics of good scheduling, high speed and high energy efficiency, and its data throughput speed can be maintained at about 8 GB/s efficiently; Combined with SRAM, the energy efficiency is improved by about 300% and the power consumption is reduced by about 72%. In the process of deep debugging with MediaTek, more than 30 patents were produced.
The performance breakthrough of the self-developed chip V 1+ is also reflected in the game performance. As the industry's first technology at this communication meeting, GPUFusion links the cooperation of multiple internal and external processors through the AI computing power of MediaTekAPU, and uses GPU*** to complete the picture rendering of the game and release the GPU load; At the same time, the hardware-level frame insertion algorithm of vivo self-developed chip is called to optimize the frame rate stability, and GLT2.0 upgrade algorithm is used to split the overloaded threads in multiple levels to achieve the effect of balancing performance and power consumption.
In terms of image, the self-developed chip V 1+ has made a deeper fine-tuning for night vision, and realized the extreme night vision function in the environment less than 1lux with video noise reduction algorithm. The extreme night noise reduction algorithm of V 1+ can realize motion prediction and compensation. Combined with the chip's own high-speed and low-power memory management system and the perfection of camera module, main chip and vivo self-developed algorithm, the mobile phone has reached the imaging level of professional night vision equipment.
On the display device side, vivo took the lead in developing XDRPhoto technology, which realized the ultra-high dynamic range display of photos. The brightness of the highlighted area of the photo can be increased by up to 350%, and the impression is brighter and more transparent.
This time, vivo also launched a brand-new AI skin technology, which "specially trained" the AI algorithm through massive high-definition materials and the confrontation network generated by GAN, making people feel as natural, healthy and more textured as skin, comparable to professional retouching works; Texture portrait photography technology can clearly present large photo scenes of up to 30 people, eliminate lens distortion and improve portrait texture; The horizon camera function solves the common problem of perspective deformation when shooting buildings.
From V 1 chip to V 1 chip, from AI skin to portrait photography, vivo constantly explores the no-man's land of mobile phone image scenes. Hu Baishan said that in the past 10 years, vivo has persisted in in in-depth research and development, polished the details, and exerted its strength in places that can't be seen, just to bring users a "super cup" experience. In the future, vivo will take 5 to 6 years to conduct technical pre-research and move in the established direction. Walk out of a road that belongs to vivo.
