Discovery, extremely fast connection, hardware mutual assistance, and resource sharing.

The operating environment of this tutorial: HarmonyOS 2 system, HONOR V30 mobile phone.

harmonyos (Hongmeng OS) is a smart terminal operating system completely independently developed by Huawei. Huawei said that they are not making another Android or another Linux, but a next-generation operating system.

harmonyos provides a unified language for the intelligence, interconnection and collaboration of different devices, bringing a simple, smooth, continuous, safe and reliable full-scenario interactive experience.

This is a distributed operating system based on microkernel for all scenarios. According to the official introduction, Hongmeng OS has four major technical features, including:

• The distributed architecture is used in terminal OS for the first time, enabling seamless collaboration across terminals and satisfying all scenarios.

• The system is smoother, application response delay is reduced by 25.7%, and process communication efficiency is increased by 5 times compared with the existing system.

• Architecture-level trusted security.

• One development, multi-terminal deployment, and cross-terminal ecological sharing.

HarmonyOS is a "future-oriented" distributed smart operating system for all scenarios (mobile office, sports and health, social communication, media entertainment, etc.) developed by Huawei. The operating system will gradually cover "1 8 N" full-scenario terminal equipment, allowing consumers to control other devices conveniently and quickly through smartphones, thereby obtaining better all-round services such as vision, hearing, feeling, and touch. In order to achieve the best user experience in specific situations, with the lowest energy consumption, the fastest speed, through the optimal hardware equipment, the most comprehensive high-quality resources are operated. HarmonyOS is not an operating system on a PC. In short, HarmonyOS is designed to connect multiple devices to form a super system with complete functions, resources, and equipment for IoT devices.

The meaning of the product architecture of "1 8 N" is: "1" represents Huawei smartphones (as shown in Figure 2), and "8" includes PCs, tablets , cars, sports and health, wearable devices (as shown in Figure 3 and Figure 4), AR/VR, smart large screens, and smart speakers. These 8 fields are Huawei’s participation in self-developed products, and N refers to a large number of IoT devices. , that is, smart devices provided by other partner manufacturers.

• For consumers, HarmonyOS can integrate the capabilities of various terminals in life scenarios to form a "super virtual terminal" that can achieve rapid communication between different terminal devices. Connection, capability mutual assistance, resource sharing, matching appropriate equipment, and providing a smooth full-scenario experience.

• For application developers, HarmonyOS uses a variety of distributed technologies, making the development and implementation of applications independent of the differences in the form of different terminal devices, reducing development difficulty and costs. This allows developers to focus on upper-level business logic and develop applications more conveniently and efficiently.

• For device developers, HarmonyOS adopts a component-based design solution that can be flexibly tailored according to the resource capabilities and business characteristics of the device to meet the operating system requirements of different forms of terminal devices. requirements.

OS system development history

China has entered the Internet era in 1994. From 3G and 4G technologies to the current 5G technology, the speed of the Internet can no longer become a bottleneck restricting online communication among users. Today, Internet users are surging, the number and types of electronic products per capita are also gradually increasing, the manufacturing process of electronic products is gradually maturing, the design and scale of various chips are shrinking, and more and more application software are emerging. As a result, IoT devices continue to increase, and the demand for services continues to increase. The development speed based on different devices cannot keep up with the continuous improvement of hardware devices. It is difficult for devices to communicate with each other. There is a lack of mature and complete businesses that can meet the huge value-added service opportunities of smart devices. mode, the contradiction between the ever-increasing number of IoT devices and the complex and fragmented user experience continues to intensify. With Internet technology as the core and user value as the guide, through the integration of cross-border vertical industry chains and the expansion of horizontal user relationship circles, we can break the industrial boundaries in the industrialization era and subvert the traditional business ecological model, and realize the ecological system of chain value reconstruction. In the context of the Internet ecosystem, the IoT ecosystem urgently needs a unified business model to organically coordinate scattered, fragmented, and independent devices or applications into a whole. HarmonyOS came into being. It not only unified management of various devices in the Internet ecosystem, but more importantly, coordinated design from all aspects of speed, performance, management, and security.

In May 2016, Hongmeng officially established a project within the software department and began investing in research and development. At the end of 2016, after completing the delivery of EMUI5.0, Wang Chenglu, who was invited by Yu Chengdong to join the consumer business department, shared Hongmeng 2 for the first time at a consumer business retreat. In May 2017, Hongmeng Core 1.0 completed technical verification. At the beginning of 2018, Hongmeng’s system prototype and cross-device collaboration functions have been basically completed. In March of the same year, shortly after Wang Chenglu reported to Ren Zhengfei in Beijing, Hongmeng officially approved the establishment of Huawei's consumer business, and the Hongmeng R&D curtain officially opened. In May 2018, Hongmeng Kernel 2.0 was used for terminal TEE. From a purely technical perspective, the Hongmeng system had already met the requirements for mobile phones at that time. The reason why it has not been used on mobile phones is that it takes time to solve application ecological issues, and secondly, it has not been used on mobile phones. This is due to the partnership with Google. On May 24 of the same year, more than a month after the ZTE incident broke out, Huawei internally accelerated Hongmeng’s research and development progress. Wang Chenglu told "Shenzhen Net", "Others say that we built Hongmeng because of sanctions. In fact, it's not the case. We have done it before, but the sanctions have accelerated our speed." On August 9, 2019, Huawei officially released Hongmeng OS 1.0 at the 2019 HDC. Yu Chengdong announced at the press conference that Hongmeng will be open source. On August 10, 2019, Honor (on November 17, 2020, Huawei officially announced the sale of 100% of Honor's equity to Shenzhen Zhixin New Information Technology Co., Ltd.) officially released Honor Smart Screen and Honor Smart Screen Pro, equipped with Hongmeng operating system.

On March 26, 2020, Huawei announced the adoption of the revolutionary "Ark Compiler" at the P30 series launch conference. The compiler is optimized on an architecture-level basis and executes machine code throughout the entire process, improving system operating performance by 24%, system response speed by 44%, and recompiled third-party application running smoothness by 60%. On June 15, 2020, the "Open Atomic Open Source Foundation", China's first open source software foundation, was officially established. On September 10, 2020, Huawei released Hongmeng OS 2.0 at 2020 HDC. At 6:18 pm, the Hongmeng code donated by Huawei to the above-mentioned foundation was open for download. As of December 2020, Huawei has released the Beta version of Hongmeng for smart wearable devices, smart screens, and car equipment to application developers. It plans to provide developers with the beta version of the mobile version of Hongmeng 2.0 in mid-December. In February, some mobile phone users will be allowed to upgrade the Hongmeng system. The initial upgrade will be verified for a few months, and then the upgrade will be fully liberalized. The Huawei P40 expected to be released in March 2021 may be equipped with Hongmeng OS.
