HarmonyOS system:
HarmonyOS OS is a distributed operating system based on microkernel, which took 10 years and was developed by more than 4,000 R&D personnel. It is oriented to the 5G Internet of Things and all scenarios. The English name of HarmonyOS System is HarmonyOS System, which means harmony. It is not a branch or modification of Android system. It is a different operating system from Android and iOS. Performance is not inferior to that of Android system. Huawei has also made a good connection for the smooth migration of applications based on Android eco-development to HarmonyOS OS-migrating related systems and applications to HarmonyOS OS, and the migration and deployment can be completed in almost two days. This new operating system will integrate mobile phone, computer, tablet computer, TV, industrial automation control, driverless, vehicle-mounted equipment and smart wear into one operating system. The system is designed for the next generation technology and can be compatible with all Web applications of all Android applications.
1. HarmonyOS system 1.0 is a Tee OS.
The Android operating system we use is actually very complicated. The earliest Android system is a JAVA virtual machine on the Linux kernel, which interprets and executes JAVA programs. Later, with the development of Android step by step, it is basically an independent operating system with a Linux kernel.
The operating system we use is not just a core, but there are many upper-level things behind a core to form a complete operating system.
For security, besides Android, there is something called Tee OS, such as mobile phones, computers and other things that use ARM chips. This thing first executes a trusted computing operating system to prevent attacks.
Ordinary Android uses a micro-operating system named Trusty as Tee OS. Huawei has developed a micro operating system for Huawei Android devices as Tee OS.
At the press conference of 20 19, Huawei named the Tee OS it has been using as HarmonyOS system 1.0, and named the Android TV that uses Tee OS instead of Trusty as the TV that uses HarmonyOS system 1.0 operating system.
In fact, Huawei's mobile phone and tablet naming is also possible. HarmonyOS system 1.0 has actually used Huawei mobile phones and tablets.
With Tee OS instead of Trusty's Android device, Huawei can name it HarmonyOS system 1.0 device.
Second, HarmonyOS system 2.0 is mainly Lite OS.
In 2020, Huawei released HarmonyOS System 2.0. Judging from the information and codes of HarmonyOS System 2.0 released at present, this HarmonyOS System 2.0 is actually an evolved version of Lite OS made by Huawei 20 16.
The operating system is actually hierarchical, with simple operating systems and complex operating systems. The operating system of embedded devices is often relatively simple and cannot support too many functions, but it takes up less space and resources and can meet some basic needs. Lite OS is something at this level.
Operating systems similar to Lite OS include RT-Thread, TencentOS tiny and so on. This operating system can be used on IOT devices, but it is rarely used on mobile phones.
At most, you can be a function machine, but you can't be a smart machine. Therefore, HarmonyOS System 2.0 released by Huawei is only used for devices with memory below 128M.
