Embedded Linux faces graphical challenges

Embedded Linux faces graphical challenges-general Linux technology-Linux programming and kernel information. The following is a detailed description. Recently, computer embedded industry research shows that Linux is the preferred Operating System for most embedded development projects. At first, Linux was just a simple solution and provided a free and powerful development platform for enthusiasts. But now it has gradually become a mature, stable, powerful and popular operating system.

Linux operating systems range from program control systems, personal digital assistants (PDAs) and household appliances to desktop systems and high-end network servers, and even powerful computing clusters and composite processor systems.

The advantages of Linux make it attractive in the entire computer field, especially in embedded systems. Compared with some proprietary embedded operating systems, the price, performance and flexibility of Linux are obvious.

Before Linux is introduced into embedded development, most embedded technology developers seldom conduct cross-platform development research, because the operating systems they use can only run on the target hardware. While Linux is gradually expanding to the battlefield in the embedded field, it also provides cross-platform development solutions, that is, application software originally developed on one platform can also be developed and compiled on other platforms, it has been widely used in the Development and Practice of embedded systems.

However, most of the new embedded solutions use the Linux system as the development platform, which does not mean that the Linux system is the only choice. There is a saying in the West: Imitating is the best way to express compliments.

At present, many manufacturers of proprietary embedded systems have also used Linux to cancel the use of their operating systems. Similarly, they imitate the open source code of the Linux system and began to provide the source code of their operating systems to consumers for free. Linux faces various challenges.

Graphical challenges of development tools

Many embedded software development projects are complex. The main reasons for this complexity are as follows:

◆ The complexity of application software may come from the algorithm used, or from the design scheme (such as a complicated customer application or server application), or both.

◆ The interaction between your applications and other application software and the operating system may also cause problems. This requires you to continuously monitor the system for a long time.

◆ System and resource restrictions may cause repeated rewriting or optimization.

◆ The standard system library and associated program design technology may not be applicable to special architectures, and users have to choose or develop other alternatives.

◆ With limited functions, it is difficult to remotely debug and maintain the application software.

Although these problems are well solved by professionals who have sufficient experience in Embedded Application Software Development and operating systems, no one can guarantee that there are always experts around. Therefore, the best solution is to use tool software to facilitate the development, monitoring and debugging of embedded software.
