Real-time applications with Linux - quantitative comparison of different approaches using the example of Industrial Ethernet realtime communication with an ARM9 platform

摘要

In the field of industrial applications, real time requirements are of high interest. Examples thereof are automation of processes or control applications. A system is called real-time-capable if a response to an event can be guaranteed within a determined time limit. Conventional operating systems like Linux or Windows are generally not real-time-capable. For the open source operating system Linux this statement is only partly true. There exist a lot of approaches to make Linux real-time-capable. By now some of them have become an inherent part of Linux. Among other things this shows the importance of real-time systems.
