摘要

Abstract

Owing to the lack of real-time in the standard Linux system,a real-time method based on Xenomai that emphasizes on user-mode real-time and can be compatible with a variety of popular real-time operating system was proposed. Build the real-time Linux sys-tem by using the Xenomai real-time patch on industrial PC and do some real-time testing. The result shows that the real-time Linux sys-tem based on Xenomai has a good user-mode real-time,excellent kernel-mode real-time and response of timer interruption,the worst time of interruption processing delays reduces to a satisfactory magnitude-tens of microseconds,and can be used for high real-time appli-cations.
