Application features of embedded Linux

Embedded Linux is widely used in the fields of application, such as information appliances, PDA, STB, Digital telephone, answering machine, screen Phone, data network, Ethernet switches, Router, Bridge, HUB, remote access servers, ATM, Frame Relay, remote communications, medical electronics, transport computer peripherals, industrial control, aerospace and other fields.

is to take advantage of many of the features of Linux itself and apply it to embedded systems.

Before listening to the teacher said that Linux to do embedded advantages, first of all, Linux is open source, there is no black box technology, a lot of Linux enthusiasts around the world is also a strong technical support of Linux developers; second, the Linux kernel is small, efficient, kernel updates

Embedded Linux

Fast, Linux is customizable, and its system core is only about 134KB minimum. Third, Linux is a free OS that is highly competitive in price. Linux also has a lot of features embedded operating system needs, the highlight is that Linux adapts to a variety of CPUs and a variety of hardware platforms, is a cross-platform system. Up to now, it can support twenty or thirty kinds of CPUs. And the performance is stable, the cutting is very good, development and use are very easy. Many CPUs including the home appliance industry chip, have started to do the Linux platform transplant work. Porting is much faster than the Java development environment. That is, if you are developing a product with a Linux environment today, you will not have trouble changing CPUs in the future. At the same time, the structure of the Linux kernel is very complete in the network, and Linux has the most complete support for the most commonly used TCP/IP protocols in the network. Includes 10 trillion gigabit, Gigabit Gigabit Ethernet network, as well as wireless network, Toker ring (Token Ring network), fiber optics and even satellite support. So Linux is very suitable for the development of information appliances.

There is a growing number of developers using Linux to develop wireless connectivity products. Linux has a very important advantage in the fast growing wireless connection application arena, which is that it has fast development speed. This is because Linux has a lot of tools and Linux is familiar to many programmers. Therefore, we want to use the Linux operating system in the embedded system.

The size of Linux is suitable for embedded operating system--linux inherent modularity, adaptability and configurable, making this easy to do. In addition, the utility of Linux source code and thousands of programmers eagerly expect it to be used in countless embedded applications, resulting in the emergence of many embedded Linux, including: Embedix,etlinux,lem,linux Router Project,loaf, Uclinux,mulinux,thinlinux,fireplug,linux and Pizzabox Linux

Compared to Microsoft, the GUI of Linux is developing quickly, such as gnome,kde,utity and so on is a very good desktop manager, and its behind a lot of community support, customizable, has been in the UNIX and Linux world spread.
