IT House, November 28, according to the official news of China Mobile Internet of things, the "China Mobile OneOS 3.0LTS Internet of things operating system Conference and Ecological Cooperation Forum" organized by China Mobile Internet of things Co., Ltd. was held online today. OneOS has served more than 350 customers, including Baosteel, Haier and Dahua, with a cumulative installed capacity of more than 30 million units.

▲ map is from China Mobile Internet of things Co., Ltd., the same as in 2019, China Mobile OneOS officially established research and development; in 2020, it launched the minimalist kernel OneOS 1.0; in 2021, it released OneOS 2.0 version that meets the functional security and information security requirements, during which it passed IEC 61508 and EAL 4 + authoritative certification. This release of OneOS 3.0 is a long-cycle support version, after extensive and in-depth testing, including a large number of security accumulation and stability improvements.

According to reports, OneOS 3.0 uses a preemptive real-time lightweight kernel design and has passed the certification of the China Software Evaluation Center of the Ministry of Industry and Information Technology-the kernel code autonomy rate is 100%. On the basis of efficient task management and scheduling, task synchronization and communication, and support for multiple memory allocation algorithms, OneOS 3.0 kernel features are further enriched.

First, OneOS 3.0supports symmetrical multiprocessor platforms to help advanced applications run more efficiently

Second, support the CPU affinity model to improve the efficiency of task execution.

Third, support MPU isolation protection, realize the isolation of kernel mode access space and user mode access space, forbid tampering in key data areas, protect code segments, and improve the security and reliability of the system.

Fourth, add maintainable and measurable functions, such as IPC tracking, interrupt detection, task trajectory tracking, partner monitoring and so on, to help developers detect the status of the system and analyze problems quickly.

OneOS kernel security and system security were evaluated by China Network Security Review Technology and Certification Center, and obtained the first domestic IT product information security classification EAL4 + certification certificate in the field of Internet of things operating system, filling the gap in the domestic Internet of things real-time operating system security technical standard and further promoting the domestic Internet of things operating system industry to a new level.

In addition, OneOS was certified by IEC 61508 SIL3 in 2021, which is one of the few real-time operating systems that have passed this certification, marking that OneOS has the necessary foundation to enter manufacturing, industrial control and other industries.

IT House learned that in terms of compatibility, OneOS supports more than 1200 chips from version 1.0 to six instruction architectures such as ARM, RISC-V, C-SKY, LoongArch, MIPS and Xtensa. In terms of interface standardization, OneOS supports three kinds of mainstream standard interfaces: CMSIS, POSIX and C++. Flexible and easy-to-use, safe and reliable, OneOS can be widely used in consumer electronics, intelligent security, industrial control and other fields.

In his speech at the OneOS 3.0 conference, Academician Ni Guangnan said: "the large central enterprises represented by the Internet of things in China Mobile have actively undertaken the task of tackling key technical problems in the country, solved the problem of key core technologies, and launched OneOS 3.0, an independent and controllable real-time operating system for the Internet of things, which has further strengthened China's technology accumulation in the field of Internet of things operating system. It has made a positive contribution to ensuring the security of the domestic industry chain of the Internet of things. "
