What factors are strongly correlated with mobile phone performance?
I believe that many people will blurt out that it is the hardware configuration of the mobile phone. In this regard, it can be said that our domestic mobile phones have never been afraid of anyone, and it can also be said that from the beginning of China's first generation of smart phones to the present, the stack configuration has long been our traditional art.
But it is undeniable that for a long time, domestic mobile phones have indeed been catching up in terms of the comprehensive performance and efficiency of smart phones - whether it is the optimization of the underlying execution efficiency of the system, or the most basic basic experience of screen "follow-up", because whenever we go deep into the optimization of any experience, it is not a simple thing.
Since the development of smart phones, I believe that many people have also understood this truth: if you want to pursue the ultimate mobile phone performance, you must start from the underlying basic technological innovations such as system software, file management and computing architecture.
If the heap configuration is compared to the first stage of simple and rough performance improvement, then domestic mobile phone manufacturers have passed this stage. The new stage is how to show stronger performance or higher efficiency in the same configuration.
Recently, vivo's new OriginOS ushered in the first version update, bringing innovation in interaction, function and visual experience again. At the recent vivo developer conference, vivo also showed the basic technological innovation and thinking behind OriginOS.

This time, on the topic of how vivo pays attention to the underlying performance of mobile phones, we also had the opportunity to have a dialogue with the vice president of vivo and the president of vivo AI Global Research Institute.
Is your phone performance strongly related to the underlying technology?
If you follow the progress of smartphone manufacturers this year, you will find that the underlying technological innovation has become an important issue in today's mobile phone industry.
As small as the time your finger touches your screen, tap to launch a certain app to show pop-up, as large as the transfer speed of files between PC and phone..... In fact, from the moment you touch the smartphone screen, it evokes the beating of characters in the digital world. The efficiency of these beating characters is strongly related to the performance of your mobile phone, and it is also the key to ensuring the fluency of the system.
Take the chirality of the mobile phone screen, in fact, the mobile phone touches the screen is a process of signal input and output, in the logic structure design, the screen animation of the system software and the hierarchical logic of the underlying architecture of the software show this efficiency.

For example, the iPhone, which is the most followed by the screen in the industry, actually puts the touch layer to the top position that triggers the decision, so when the hand is detected touching the screen, it starts the whole level of the mobile phone to serve the goal of following the hand.
As you can see, it is actually a logical optimization for a specific scene.
Another example is to put this specific scenario in terms of mobile game performance. If the system can detect that you are opening the game at this time, you can also ignore those tasks that are not high-level to mobilize all resources to the performance of the mobile game.
Of course, these metaphors are simple.
Converting to the digital world, due to the large number of scenarios, it must not be done in a single way in the form of functional module optimization. From the overall consideration of the underlying layer, it is actually the overall optimization of the overall kernel, logic level, and computing resource use and scheduling of the mobile phone system. From compilation, storage, and computation transfer, it needs to be completely redesigned.
Obviously, this is a very complex project.
In an interview with Pin play, the surrounding said that the mobile phone today is mainly divided into the driver and kernel layer, the former is the world's mainstream three major chip suppliers, Qualcomm, Samsung and MediaTek, terminal manufacturers in this above the trend is actually the upstream definition of the trend. At the kernel level, it can be said that it is the place where terminal manufacturers can open the gap today.
In this regard, vivo has planned a complete kernel.
Kernel, deep into the infrastructure of the phone
The kernel of the mobile phone system, to a more popular naming method today, is actually to go deep into the infrastructure of the mobile phone.
In order to give you an idea of what the basic technology field of mobile phones means, I have thought of a fairly appropriate metaphor.
We assume that the basic framework of the Android system provides a set of rough house models, and the system UI is actually the manufacturer's fine decoration design on this rough house. When this house is delivered, in fact, it has transformed the basic pipeline facilities of water, electricity, and gas buried in the wall for you, but even if the house has a good-looking fine decoration, if the water, electricity, and gas roads are not passable or easy to block, then the house will have anti-water, anti-gas conditions.
So if you want this house to improve the efficiency of the basic settings of water and electricity, you need to go deep under the walls of this house and carry out the transformation and design of these pipes on a lower level.
You must have a certain engineering and technical theory, and a strong hands-on ability.
In recent years, after stepping through the threshold of systematic decoration of the house, vivo has also begun to transform these "hydropower" basic technology fields.
Vivo vice president and president of vivo AI Global Research Institute said in an interview with Pin play that there are actually three important issues on how to create a strong performance of mobile phones:
The first is to establish a complete scientific human factor analysis to figure out what kind of parameters are the most comfortable in various scenarios; the second is to do a good job in flow construction, so that the interaction and dynamic effects of vivo mobile phones are in line with people's physiological characteristics and psychological expectations; the third is to focus on computing, storage, display and full scene fluency, and achieve the performance to the extreme.
It is worth paying attention to the third point, in the calculation, storage, display and full scene fluency, the first three can actually be counted as the "infrastructure" in the system field, that is, if the water, electricity and gas can not be supplied fast enough, then I believe that buying good electrical appliances can not actually change the fact of inefficiency.
In the renovation, we all know that the wall should be dug up to re-wiring.
Of course, this also requires you to combine the most popular decoration methods, of course, the most popular decoration methods are definitely combined with the starting point that makes people more and more comfortable.
In terms of computing performance, vivo mainly plans high-performance computing units to break through the hardware limits. The reason is that after the outbreak of the mobile Internet, Vivo found that users often do some high concurrency actions, vivo created a high real-time computing engine: with a continuous start of 20 applications to do testing, start a round of time, increased by 20%, two consecutive rounds of startup time, increased by 30%, high concurrent computing mode to ensure that the system multitasking operation fast, smooth, switching is not stuck.
In terms of storage performance, in order to break through the limitations of RAM itself, memory fusion technology has also come to 2.0, vivo builds a virtual cache unit inside the mobile phone system, and comprehensively optimizes the memory management mechanism - if you are a vivo OriginOS user, you will find that last year's memory fusion can achieve the effect of 8G+3G, this year has come to 8G+4G, and the mobile phone can be directly expanded to a mixed 12G RAM state, which greatly improves the execution efficiency. Let the mobile phone use for 36 months and no longer stutter, which is actually a major demand of many vivo users today.
In order to keep the resident memory in a lower and healthier state, the vivo engineer team also optimized the performance of the compiler, and the resident memory after the system was turned on was optimized for 800M, from the previous 4.5G memory occupation to the current 3.7G. Do comparative tests, ordinary 8G configuration of the machine, the maximum number of applications that can be active in the background is about 14, memory fusion 2.0, vivo finally achieved the highest number of background active applications to 28, the effect is very close to the real 12G memory of the machine.
Ultimately, it is also reflected in the display performance, and the visual comfort direction has become one of the most important performance indicators for vivo to evaluate the display performance internally. On the basis of the atomic motion engine launched last year, vivo has developed quasi-water surface physical motion, simulating the buoyancy and damping of the water surface in the physical world, increasing the naturalness and pleasure of the motion experience, and causing users to resonate with smooth motion from the psychological level.
In order to improve the display fluency of third-party applications, the UI rendering layer of the application, the delivery and response of touch events are first identified, and the independent priority is increased when allocating computing resource allocations to these objects. Vivo took the game frame rate stability to do a comparative test, and the actual measurement finally increased by 63%.
Mobile phone systems, how to carry the digital and physical world
According to the understanding of the product play, the current vivo Android kernel research and development team size is about 400 people, of which the middle framework layer and the basic tool chain layer invested about 100-150 people, in the kernel, driver layer invested in 200-300 people.
With the investment of huge human, material and financial resources, based on the capabilities of computing, storage, display and other aspects, vivo has also truly achieved the smoothness of the whole scene under the daily high-frequency use scenarios such as application startup, content loading, visual fluency, touch perception, multi-task concurrency and network operation.
While mobile phones are efficient and easy to use, the system has naturally become a connector between the digital world and the physical world.
Tearing down the wall, based on the transformation of the underlying performance of the mobile phone, is actually opening up a larger technology world, and will also produce some new understanding of how technology serves functions.
It is worth noting that at the developer conference vivo showed the quick bumper for the first time. It has built-in vivo's new NFC operation protocol, which is closely integrated with vivo's smart life, and can quickly control smart devices with one touch, and the elderly and children can easily operate. Touch it and quickly enjoy the new life of wisdom. Once you touch the Internet, guests no longer have to ask for wifi passwords; once you touch the screen, you can cast the content of the mobile phone to the TV or computer; there are also functions such as making a phone call and checking the weather.
One touch opens the smart scene. Before leaving home, you can turn off the air conditioner and lights at a touch, becoming an energy-saving home master; after returning home, you can turn on the air conditioner, lights and water heater at a touch to enjoy a leisurely family time.
Strong monomer performance may be what everyone wants, but in the end, how to achieve the best balance of performance and ecology is the next level of challenge that vivo considers.
It is understood that at present, vivo's products cover more than 400 million users around the world and serve more than 60 countries and regions. Next, vivo's challenge will be how to continue to seek ways to connect with future consumers and ecosystems in terms of products, technologies, platforms and services, while striving to improve the ability to match such needs.
Shi Yu, senior vice president of Vivo, insisted that Vivo is promoting deeper and broader Internet penetration to achieve a greater ecological win-win situation. By creating infrastructure services, we will open up the complete product matrix, system technology capabilities and platform capabilities to partners and help them better serve consumers.
On this path, vivo must regard the system as a long track that focuses on layout. Continue to focus on software-level construction to help users in the physical world better access to the content and services provided by the digital world.
