Embedded basic software is embedded operating system. The current operating system also conforms to the characteristics of differentiation mentioned above: there will be different mainstream systems in different fields. For example, VxWorks is mainly used in industries with high safety requirements, such as aerospace, rail transit and medical treatment. Android and iOS are mainly used in handheld smart terminals; Embedded Linux is more widely used.
In general, embedded operating system requires tailoring, scalability, portability, high stability and several major characteristics.
Professional embedded devices can also have universality and openness, typical embedded devices can contain a complete operating system, device drivers, networks, files, graphics processing and a variety of applications, has begun to PC. The benefits of PCization are low cost portability of other applications and better human-computer interaction.
Combined with the development of computer technology and industry application, embedded computer system has slowly become the leading role of the information industry, the rising star of the computer era, and with the continuous progress of embedded technology, handheld terminal devices with convenient portability, small size and other characteristics are widely used in various fields of life.
