What is an embedded operating system?

The embedded operating system is an operating system software that supports embedded system applications. It is an important part of embedded systems. When embedded, the operating system has the basic features of a general-purpose operating system, which can effectively manage complex system resources and virtualize hardware.

Traditional definition (narrow definition): The embedded system is application-centric, based on computer technology, and can be tailored for hardware and software. It is suitable for application systems with strict requirements on function, reliability, cost, size and power consumption. computer system.

Current objective definition (pan-embedded): All computer systems except PC can be called embedded systems. Typical representatives: smartphones, industrial robots, automotive electronics, aerospace (four-axis aircraft), security monitoring (IPC), etc.

Embedded operating system classification

From the application point of view can be divided into a general-purpose embedded operating system and a dedicated embedded operating system. Common general-purpose embedded operating systems are Linux, VxWorks, Windows CE.net, and so on.

Commonly used dedicated embedded operating systems are Smart Phone, Pocket PC, Symbian, and so on.

According to real-time, it can be divided into two categories: Real-time embedded operating system is mainly for control, communication and other fields. Such as WindRiver's VxWorks, ISI's pSOS, QNX system software company's QNX, ATI's Nucleus and so on.

Non-real-time embedded operating systems are primarily targeted at consumer electronics. Such products include PDAs, mobile phones, set-top boxes, e-books, WebPhone, and more. Such as Microsoft's Smart Phone operating system for mobile applications.
