In the booming smartphone waning, calls for the wearable and intelligent household iot has raged, virtual reality middle fight, stir up day by day calm intelligent terminal backwater, and injected a wave of new vitality into the terminal market.
Including the upper reaches of the ARM architecture manufacturers, chip makers core micro, qualcomm. Middle reaches of the scheme in kechuang ShangXiM flux, and the downstream manufacturers cut quickly, such as great friends, Pico to up and down with a wave of hardware trend. And these vendors in which also seriously, the ingenious methods.
A few days ago, red core micro docking summit held a VR industry chain, to analyze the current situation and prospect of VR industry.
ARM: support VR from the architecture
VR as a isn't a new product, with three different forms of terminal: VR all-in-one PC, PC and box (used with mobile phone). The immersive experience in practice, however, also let VR brought a variety of application requirements.
VR applications
Due to its working principle and experience of the rigid requirements, that not only should improve on chip level, from the perspective of software to optimize is needed. In addition, how to combine the upper includes a variety of auto parts, machinery parts, accessories and on cost, performance, and products to consumers brings extreme experience, become participants in the industry of responsibility.
ARM as a chip, the upstream providers to VR industry power from the source. As a IP vendors, ARM services including its product line of CPU and GPU, due to the features of VR, strong performance requirements are put forward for the ARM.
The ARM how to build a new experience for VR
ARM to think, to VR products have the best experience, then ask its experience to PS4 level of this kind of host, and the deadline will be in 2018, when the ARM CPU and GPU will bring the strong power to VR. Came to the key field of the GPU, the performance of the ARM is unrivalled.
As the absolute king of mobile processor, ARM Mali gpus from 2008 since its launch, gradually occupied a place in the field of mobile GPU. Came to the field of VR, with its excellent image processing performance, OpenGL ES and EGL delay optimization, reduce the bandwidth of system and improve the ecological features, ARM GPU will become the VR GPU came out.
ARM Mali GPU development roadmap
ARM before the latest architecture - A73 CPU architecture and GPU architecture G - 71, it is in the field of VR endeavour of concrete.
Rui core micro: RK3399 relay RK3288 storm VR market
Domestic chip manufacturers, red core is considered a walk in the front, with a RK3288, red core micro occupied domestic market more than 80% of the VR, well ahead of other competitors, but this year they launched a new RK3399, for VR master more reinforcements.
According to core micro Rockchip global vice President of ucg, RK3399 adopted double architecture A72 large nuclear + 4 architecture (A53 small nuclear big. The nuclear structure, LITTLE size and do to integers, floating point, memory and other sharp optimization, products in such aspects as in overall performance and power consumption has a revolutionary improvement.
RK3399 is adopted, for example, in respect of the GPU ARM of a new generation of high-end image processor - Mali - quad-core T860, in addition to the integration of bandwidth compression technology, such as intelligent superposition, ASTC, local pixels stored outside, also supports more graphics and computing interfaces, the overall performance is 45% more than the previous generation.
Ucg, points out the positioning in the high-end VR all-in-one chip solution, not only supports the three major VR new industry standards - 20 ms millisecond delay, and more than 75 hz refresh rate and more than 1 k gyroscope refresh rate, also has eight major technical advantages:
1, super 4 k 360 - degree panoramic video decoding, and compatible with the 2 d / 3 d sources
2, VR low latency less than 20 ms, ms Android upgrade 5 times more than before optimization
3, display frame refresh rate support 75 hz - 120 hz
More than 4, 300 million, triangle output rate
5, support 2 k/double FHD high-resolution screen
6, support optical software against distortion, dispersion, pd control algorithm
7, supporting software and hardware about two split screen mode
8, support mainstream game engine platform
Add rich interface support, high performance of ISP, for Android and Linux compatibility, also let RK3399 in core micro strengths domains such as the traditional game box and epoxy resin plate continued to be strong. Considering the RK3288 support for Windows and chrome OS, must have the new flagship in the future also will add support for the two systems, which makes the RK3399.
Nibiru: for VR bridge structures, the physical world and virtual world
Mentioned earlier, VR is a high demand for hardware and software of the product form, how to build a communication in the physical world and the virtual reality world of simple bridge, is the prime problem of the developers need to consider. Nanjing farce of yue (Nibiru) is the best.
Depends on the hardware in the underlying system optimization, performance optimization, the gyroscope fusion algorithm and asynchronous time distortion, and other fields of technology accumulation, Niburu leading research and development of Nibiru SDK system through interactive VR SDK (interaction, audio, graphics SDK SDK) established through the core technologies such as software, hardware, system of upstream and downstream, service developers around the world. Nibiru VR all-in-one system occupies the absolute market share, Nibiru VR handset system adopted by several brand mobile phone.
Nibiru, co-founder of Liu Fengrui think, PC form or VR in the form of mobile terminal, due to the lack of closed or experience of the industry chain, will not die VR's final choice, he thinks the future of VR is all-in-one.
He noted that although the upstream chip makers will chip performance and scheme has done very well, but these do not represent can make a good product, it also need the hardware design of the company's various inputs in the middle. To set up a perfect VR ecosystem, also need to have content such as audio and video, game, vendors, on the application and various peripherals manufacturers to cooperate. In this way can we build a set of scenarios of VR applications. Based on these logic, Nibiru, from the perspective of the interactive SDK, cut into the underlying optimization, power IDH design, joint brand, the ability of manufacturing and supply chain, the product set off the market.
Liu Fengrui thinks, want to VR outbreak, a problem needs to be addressed is dealing with the optimization of gyroscope, including the stability and image rendering.
In his view, although now mobile VR GPU are following a PC graphics performance, but we need to understand that much of a gap, so for the VR on complex load content, will need to consider. Rui-feng liu think VR devices, although can do complicated content, but one thing need to pay attention to, it is apply colours to a drawing must be as simple as possible, because it can relieve the pressure of the GPU.
Nibiru now ARM to do some of the underlying optimization and construction, the delay of VR devices do less than 30 ms, the refresh rate can also be based on the performance of the main control chip to raise it to 90 FPS.
In VR audio and video games, etc., Nibiru have united the content and game industry chain of many domestic manufacturers, is committed to provide consumers with a new experience. Here, liu2 zong3 specially mentioned the VR application in recent hot live platform. He believes that the future will become a mainstream VR live, provided by the core algorithm here Nibiru and rendering technology, also has incomparable advantage over other platforms.
Silicon valley da: USB Type C power phone VR market took off
The USB Type C is the bestselling technology in recent years. Thanks to the positive and negative plug, high transmission speed and support for high power, USB Type C gradually become the mainstream of mobile devices in recent years, even the Intel in vigorously promoting the popularization of Type C. VR as a kind of mobile devices, no doubt, has become a hot spot in the USB Type C.

Silicon valley da Christopher lau believe that mobile phones and VR display connection "VR can connect" will be the best performance and portable combined with VR products.
Different forms of VR on equipment requirements
Christopher lau continue to point out, such as HTV VIVE such VR device connected to the PC, not only need HDMI audio and video transmission, also need to VR line to transmit data, combined with the power cord, not only the connection is various, and the use is restricted; But similar Google Cardboard type of VR terminal while the cost is low, but is limited by the performance of the mobile phone, combined with the weight of the "moving", the serious influence the experience of consumers.
So mobile phone connection VR will be a better product configuration, Christopher lau emphasized. If VR in this mode, you can use a Type C cable meet the demand of power supply, data, audio and video transmission. Including acceleration gyroscope, location, a front-facing camera, and so on aspects of the information can be transmitted through its, Christopher lau added.
According to Christopher lau, the use of USB Type C to transmit data, is the inevitable outcome of the development of performance requirements.
The USB Type C VR data transmission become the preferred
The USB transfer Type C is follow the DisplayPort interface standards, through mathematical model developed in silicon valley SlimPort chip support to create simple connection between mobile devices and display technology. Can significantly reduce the cost of the developer and the complexity of the product design.
In addition to these technology provider, there's links, such as plan, provide the integration of 3 dv star provides the algorithm of 3 d and optical support, Shanghai le phase, PI Airpi, red crystal imaging, 3 dvstar, goods net, morning core, British companies like card from VR industry chain, and cut the stages of the development of VR industry of China. Under the joint efforts of the manufacturers, the real popularity of VR just around the corner.
