Huawei mobile phone has officially decided to adopt harmony OS! On September 10, at the 2020 Huawei developer conference, Yu Chengdong, CEO of Huawei's consumer business, officially released Hongmeng OS 2.0, and announced that Huawei Hongmeng OS fully enabled the full scene ecology, and would release the mobile version in December 2020.
Hongmeng OS 2.0 released, will launch smartphone version
The coming of Hongmeng OS 2.0 is no surprise.
At last year's Huawei developer conference, in 2019, Huawei officially launched a global distributed operating system, harmonyos, for all scenarios. Since then, various intelligent terminals have realized rapid discovery, fast connection, hardware mutual assistance and resource sharing.
In this developer conference, harmonyos 2.0 was officially unveiled, which brought the comprehensive upgrade of distributed capabilities such as distributed soft bus, distributed data management, distributed security, etc., and released an adaptive UX framework, which enabled developers to quickly reach tens of millions of new devices and users.
Huawei said that Hongmeng OS 2.0 system is the first truly distributed operating system built for the full scene era. Through cross device collaboration, large and small screen interaction, high-speed distribution network, adaptive UX, visual AI enabled voice interaction, developers open source, etc., it adds wings to imagination and becomes a powerful engine of ecological construction.
Huawei said that Hongmeng OS will be officially open-source, and developers will get simulators, SDK packages and IDE tools. The beta version of Hongmeng OS for smart phones will be released to domestic developers at the end of 2020.
Yu Chengdong said in his speech that Huawei donated the code to the China open atomic open source foundation and announced the open source roadmap of Hongmeng OS
From September 10, Hongmeng OS will open source devices with 128kb-128mb memory for large screen, watch, car and other terminal devices. In April 2021, it will open source 128mb-4gb memory terminal devices. After October 2021, it will open source all devices above 4GB.
In response, Yu Chengdong, CEO of Huawei's consumer business, said:
Huawei's breakthrough in ecological construction is inseparable from the strong support of global developers and partners. At this developer conference, Huawei will fully open its core technology, software and hardware capabilities, and work with developers to drive the vigorous development of the whole scene intelligent ecology. No one can extinguish the stars. Every developer is the spark that Huawei wants to gather.
At the scene, Wang Chenglu, President of Huawei's consumer business software, said that Hongmeng OS would build a complete platform tool chain and ecology for developing full scene applications.
Specifically, it includes the following contents:
Hongmeng OS application framework: suitable for full scene application development framework;
Huawei deveco: one time development, multi terminal deployment;
Ark compiler: multi device multi language compiler (Java / JS);
Distributed application: full scene innovative application.
Wang Chenglu also said that after testing and verification, Hongmeng OS has been able to support seven chips of five brands, five modules and eight development boards, involving WiFi, cameras and screen display chips, and its solutions have covered two important partners.
It is worth mentioning that the newly released emui 11 also carries the core distributed technology of Hongmeng OS, which is no longer limited to the interaction between mobile phones, but also realizes the IOT running Hongmeng OS The interaction of devices brings users refreshing full scene experiences such as extremely fast distribution network, minimalist interaction and direct service. For example, mobile phones call large screen cameras for smooth video calls, mobile phones connect with smart home devices equipped with Hongmeng OS through touch and feel free networking, and household appliances change from "no screen" to "screen".
Wang Chenglu also said: smartphone users who upgrade emui 11 will definitely take the lead in upgrading to Hongmeng OS.
Four technical characteristics of Hongmeng OS
At last year's Huawei developer conference, Hongmeng OS made its debut.
Huawei said that the original design of Hongmeng OS is to meet the high standard connection requirements of full scene intelligent experience, so Huawei has proposed a system solution with four characteristics.
Specifically, it is as follows:
For the first time, the distributed architecture is used in terminal OS to realize seamless cross terminal collaborative experience of "distributed OS" of Hongmeng OS "Architecture" and "distributed soft bus technology" shield the application developers from the difficulty of realizing the underlying technology of corresponding distributed applications through the four capabilities of public communication platform, distributed data management, distributed capability scheduling and virtual peripherals, so that developers can focus on their own business logic, develop cross terminal distributed applications like developing the same terminal, and also make the final consumers Enjoy the seamless experience brought by the powerful cross terminal business collaboration ability for each use scenario.
The deterministic delay engine and high performance IPC technology are used to realize the natural fluency of the system. The determined delay engine can allocate the priority and time limit of task execution in the system before task execution. The task resources with high priority will be given priority to guarantee the scheduling, and the application response delay will be reduced by 25.7%. The compact structure of Hongmeng micro kernel greatly improves the performance of IPC (interprocess communication), and the process communication efficiency is 5 times higher than the existing system.
Based on the micro kernel architecture, the trusted security of terminal devices is reshaped. Hongmeng OS adopts a new micro kernel design, which has stronger security features and low delay. The basic idea of microkernel design is to simplify the kernel functions, implement system services as much as possible in user mode outside the kernel, and add mutual security protection. Microkernel only provides the most basic services, such as multi process scheduling and multi process communication. Hongmeng OS applies microkernel technology to trusted execution environment (TEE) and reshapes trusted security through formal methods. Formal method is an effective way to verify the correctness of the system from the source by using mathematical methods. Traditional verification methods, such as function verification and simulation attack, can only be verified in selected limited scenarios, while formal methods can verify all software running paths through data model. For the first time, Hongmeng OS applied the formal method to terminal tee, which significantly improved the security level. At the same time, because the code volume of Hongmeng OS microkernel is only one thousandth of that of Linux macro kernel, its attack probability is greatly reduced.
Through the unified ide to support one-time development and multi terminal deployment, Hongmeng OS realizes cross terminal ecological sharing. With multi terminal ide development, multi language unified compilation, distributed architecture kit provides screen layout control and automatic adaptation of interaction, supports control drag and preview oriented visual programming, so that developers can efficiently build multi terminal automatic operation based on the same project App can realize real one-time development, multi terminal deployment, and realize sharing ecology between cross devices.
It is worth mentioning that Hongmeng OS is based on Huawei ark compiler. Huawei ark compiler is the first static compiler to replace Android virtual machine mode, which can be used by developers to compile high-level language into machine code in the development environment. In addition, the ark compiler will support multi language unified compilation in the future, which can greatly improve the development efficiency.
