Sun's Java operating system, Langxun Technology company's Inferno, embedded Linux, etc. This type of system passes through
Long-term operational tests such as computer or high-performance computers, technology is increasingly mature, related standards and software development
The way has been widely accepted by users, while accumulating rich development tools and application resources.
Another type is a real-time operating system, such as Windriver's VxWorks, ISI's PSOS, QNX System Software
The company's QNX, ATI's Nucleus, Chinese Academy of Sciences Kesi Group's Hopen embedded operating system, etc.
Products in the structure and implementation of the operating system, the real-time high reliability, etc.
Design, and provide independent and complete system development and test tools, more use in military products and industrial controls
In the field of system.
Linux is an open source operating system that has been gradually mature since the 1990s. Linux version on the PC
Under the development of millions of enthusiasts in the world, it has been developed very rapidly. UCLinux at the end of the 1990s,
RTLinux, etc., have been launched in the embedded area, which has a large number of programmers and ready-made
Using procedures, it is a valuable resource for our research and development.
