Advantages of Embedded Linux

Embedded systems have already penetrated into many industries. They were initially used to control Electromechanical telephone switches. However, this article describes the advantages of Embedded Linux and Linux as embedded operating systems, many advantages of Linux are that it has been widely used in the embedded field, and a considerable number of Embedded Linux systems have emerged.

Linux is a mature and stable network operating system. Embedded Linux has many advantages. First, the source code of Linux is open. Anyone can obtain and modify it and use it to develop their own products. Secondly, Lirmx can be customized, and its system kernel is only about kb at the minimum. A core program with a Chinese system and graphic user interface can also be less than 1 MB, and it is also stable. In addition, it is compatible with most Unix systems and is quite easy to develop and transplant applications. At the same time, due to its good portability, Linux has been successfully run on hundreds of hardware platforms.

Linux as an embedded operating system has the following advantages:

1. It can be applied to multiple hardware platforms. Linux has been transplanted to multiple hardware platforms, which is attractive for research and development projects with limited funds and time. The prototype can be developed on the standard platform and then transplanted to the specific hardware to accelerate the software and hardware development process. Linux uses a unified framework to manage hardware. Changes made from one hardware platform to another are irrelevant to upper-layer applications. Linux can be configured at will, without any license or business partnership, the source code can be obtained for free. This makes it possible to avoid any copyright disputes when using Linux as the operating system. Undoubtedly, this will save a lot of development costs. Built-in network support, while embedded systems require more and more network support. Highly modular Linux makes it easy to add components.

2. Linux is a Unix-like, kernel-based, with full memory access control and supports a large number of hardware (including X86, Alpha, ARM, Motorola, and other existing chips) is a common operating system. The program source code is publicly available. Anyone can modify it and issue it under the GNU General Public License. In this way, developers can customize the operating system to meet their special needs.

3. Linux has comprehensive development tools familiar to Unix users, and almost all Unix system application software has been transplanted to Linux. Linux also provides powerful network functions, including multiple Window managers (X Windows ). Its powerful language compiler GCC, C ++, and so on can also be easily obtained, not only mature and complete, but also easy to use.
