Yesterday the Vivo Developer Conference 2021 was held in Shenzen with the theme "From 1 to infinity". In this conference Vivo discussed with the participants about future trends and opportunities for updating the experience and technological cooperation, among other things.
Vivo Developer Conference 2021: here are the technologies on which the Chinese manufacturer focuses
Shi Yujian, senior vice president of vivo, said: “2021 is the first year of the qualitative change of vivo. Consumers move from "choice" to "love", from "satisfaction" to "active recommendation", so we use great products to build consumer favorite brands. "
In terms of processing performance, Vivo has designed three engines for real-time processing, intelligent scheduling processing and high-speed monitoring. Simultaneous high-performance processing can be achieved through a real-time processing engine to ensure fast and smooth system multi-tasking; through the intelligent planning calculation engine to give full play to the system's computing power, achieve a perfect balance between performance and power consumption, the maximum power consumption can be reduced by about 10%; The high-speed chase loading engine can instantly improve system performance, quickly reduce the time when the CPU is fully utilized, and increase the CPU frequency by 200% to achieve instant acceleration.
In terms of memory performance, vivo believes that it is necessary to establish an independent virtual cache unit to achieve systemic overall management of the system resident memory lifecycle, application memory allocation and recovery, and internal DRAM and SoC cache, so that memory management is more efficient and high performance. To this end, vivo has updated the memory integration to version 2.0. Through multi-level precision processing compression and swapping, some of the ROM storage space is programmed to use RAM and the virtual cache unit is built by effectively managing system resident memory to fully optimize memory.
In terms of display performance, vivo believes that display capability is one of the most important performance indicators. Therefore, based on the atomic motion engine, the industry's first pseudo-surface physical motion effect was developed specifically to simulate the buoyancy and damping of the water surface in the physical world. The naturalness and pleasure of the movement experience, from the psychological level, arouses the resonance of the user for a fluid movement. At the same time, vivo also improves the priority of interactive UI rendering via a full link to ensure smoother viewing of third-party applications.
In addition, according to the capabilities of processing, storage, display, etc., vivo also realizes fluid full scenes in high frequency daily use scenarios such as application launch, content loading, visual fluency, perception of the touch, multi-task concurrency, and network operation.
In addition to maximum performance, vivo also greatly improves the user experience in all aspects of life through software updates and other methods. In response to users' signal or network instability problems in life, vivo adopts unique and leading radio frequency antenna design and continuously optimizes antenna intelligent switching technology to solve the antenna signal blocking problem from the posture of the handheld; antenna performance doubled. It also uses a power boosting algorithm to increase the low latency ratio by 8% and ensure a better network experience.
In terms of WIFI and Bluetooth, vivo has become smarter and more compatible. AI technology is used to identify weak Wi-Fi network usage scenarios, including blocking Wi-Fi video viewing, slow internet access when you leave, and the system can intelligently select the best network. Network stall rate in case of weak Wi-Fi network is reduced by 20%. At the same time, vivo builds a typical user environment in a professional WiFi lab, covers 95% of home routers on the market and implements 7 * 24h automated tests of various kinds.
Finally, aiming at the optimization of Bluetooth compatibility, vivo performs full-link and omnidirectional control from the three dimensions of device width, scene width and scene depth. After systematic improvements, the stability of the Bluetooth connection has increased by 30% compared to last year and the fluidity rate of the Bluetooth sound has been increased by 20% and is committed to improving the Bluetooth compatibility in "all devices and all scenes" .
