The same chip, stronger experience, deep joint adjustment to release the performance potential of Tianji 9000
As MediaTek's flagship platform, the Tianji 9000 has received widespread attention from the market for its excellent performance and outstanding energy efficiency since its release. As strategic technology partners, Vivo and MediaTek have invested in an elite development team of more than 300 people since last year, and after 350 days of in-depth collaborative development of software and hardware, the V1+ chip and the Tianji 9000 are adjusted and adjusted, releasing the strongest performance of the Tianji 9000.

In order to improve the energy efficiency ratio of the Tianji 9000 platform, Vivo uses the algorithm to adjust the CPU resource allocation strategy to reduce heat generation, and solves the problem of performance probability fluctuation after several iterative tests, effectively improving the energy efficiency ratio of the Tianji 9000 platform. The test results show that in the game scenario of high performance requirements, the Tianji 9000 can extend the battery life of the game by 10%.
In order to bring users a smoother long-term machine experience, vivo has established a complex set of "user use scenario fluency model", optimized the allocation of computing power, improved the priority of animation tasks, and increased the overall animation fluency under high load scenarios by 50% ; and effectively solved the problem of CPU resource preemption and idleness by designing a high concurrency computing mode, greatly optimizing the continuous startup speed of the application; using a new memory resource management scheme to establish a virtual cache unit to improve data processing speed. Improve the overall fluency of user usage scenarios, and achieve up to 36 months of anti-aging fluency experience - so that high performance and low power consumption to achieve "fish and bear paws".

Continue to promote the hardwareization of algorithms and create a second-generation dual-core standard
In order to break through the computing power constraints of the general computing unit on mobile phone images and performance, vivo began to promote the hardware of the algorithm since 2019, and officially launched the first self-developed image chip vivo V1 last year.
At this communication meeting, vivo launched the second generation of self-developed chip V1+ and the second generation of dual-core standards: not only evolved again at the image level, but also expanded the chip functions to the field of performance and display, expanded support for game and video visual experience, and achieved a "core" for two uses. So far, vivo has not only become the first terminal mobile phone manufacturer to complete the tuning with the MediaTek flagship platform on the self-developed image chip, but also the only mobile terminal manufacturer in the industry that has realized the self-developed image chip compatible with the multi-flagship platform.

One "core" two uses, breakthrough performance game experience
Vivo self-developed chip V1+ will be 3D real-time stereoscopic night scene noise reduction, MEMC interpolation and AI super-division three algorithms for hardware packaging, with good scheduling, fast speed, high energy efficiency three characteristics, its data throughput speed can be efficiently maintained at about 8GB/s; combined with SRAM, the energy efficiency is increased by about 300%, power consumption is reduced by about 72%. In the process of in-depth joint commissioning with MediaTek, more than 30 patents were generated.

The performance breakthrough of the self-developed chip V1+ is also reflected in the performance of the game. As the industry's first technology at this communication meeting, GPU Fusion through the AI computing capabilities of MediaTek APU, linkage of internal and external multiple processors to work together with the GPU to complete the game's screen rendering, release GPU load; at the same time call vivo self-developed chip hardware-level interpolation algorithm to optimize frame rate stability, the use of GLT2.0 upgrade algorithm multi-level split overload thread, to achieve the effect of performance and power balance. For some hardcore players, vivo also opened the GPU Settings Panel to customize the screen display effect and visual experience.

One "core" two uses, hardware-level computing photography to a new height
In terms of imaging, the self-developed chip V1+ continues to lead the industry as the core hardware of the algorithm. The in-depth refinement of night scene video is carried out, and the polar night video function of less than 1lux environment is realized by video noise reduction algorithm. V1+ polar night noise reduction algorithm can achieve motion prediction and compensation, combined with the chip itself high-speed, low-power extremely fast memory management system, with the camera module, main chip and vivo self-developed algorithm to improve, so that the mobile phone has reached the imaging level of professional night vision.

In addition to multi-platform support and in-depth tuning, vivo also digs deep into the capabilities of the V1+ chip, extends the black light night vision function to the front and wide-angle lenses, covers all scenes in all time and all focal lengths, and comprehensively improves the camera and video capabilities of mobile phones.
The combination of two cores expands the imagination of the image world
Vivo V1+ has also brought real changes to users in terms of image experience.
The first is color. Vivo proposed the "vivo memory color system": vivid, bright and textured vivo vivid colors, as well as the pursuit of faithful restoration of human eye vision, the pursuit of the ultimate color performance of ZEISS natural color, from the detection, shooting, processing, display of the four dimensions to carry out full-link color management.

Starting from automatic metering technology, vivo launched the "AI perception engine" technology, which integrates the experience of top professional photographers into the chip algorithm to become the hub of visual understanding, corrects the image information in the form of real-time preview, and increases the brightness accuracy by up to 16% compared with the traditional metering method, and the white balance accuracy by up to 12%.
On the display device side, Vivo first developed its own XDR Photo technology, which realizes the ultra-high dynamic range display of photos, and the brightness of the highlighted area of the photo can be increased by up to 350%, and the look and feel is brighter and more transparent, giving users a more immersive experience.

In the shooting session, vivo V1+ increased the ΔE of ZEISS natural colors by about 8.3% on the basis of about 15.5% compared with the past, and made the tone of ZEISS real colors more excellent through fine tone.
The second is the portrait. Vivo makes technological breakthroughs before, during and after portrait shooting: helps users cope with complex and diverse portrait scenes by calibrating and adapting; launches the ZEISS portrait lens package, which provides a variety of classic portrait bokeh styles; and obtains professional texture portrait works through the portrait algorithm matrix.
(Four professional standards, bringing professional texture to the portrait works)
The vivo also launched a new AI skin technology, through a large number of high-definition materials and GAN generation confrontation network to "special training" of AI algorithms, so that the portrait skin looks natural, healthy, more textured, comparable to professional retouching works; texture portrait large group photo technology, can clearly present up to 30 people of the big group photo scene, eliminate lens distortion, improve portrait texture; horizon photo function is a good solution to the common perspective deformation problem when shooting architecture.

From V1 chips, to V1+ chips, from AI skin textures to portrait photos, vivo continues to explore the no-man's land of mobile phone image scenes, constantly surpassing its own limits and achieving the peak of imagery. Hu Baishan said that in the past 10 years, vivo has insisted on in-depth research and development, polished details, and made efforts in places that cannot be seen, just to always bring users the experience of "super cup", which will also be reflected in the upcoming vivo new generation flagship model - X80 series.
The X80 series is a great achievement of vivo's long-term scientific research in technology. In the future, Vivo will also use up to 5 to 6 years of technical pre-research, in the direction of its own setting, according to its own rhythm, out of a path belonging to vivo.
