Abstract

Recently, there is a growing need for an open software platform where developers easily write intelligent motion control applications for smart cars. Smart robots, smart factories, and so on. To this end, a general purpose operating system with rich functionalities and various hardware supports can be a candidate for such a platform, but it is known to have limitations in guaranteeing the responsiveness of individual applications. In this paper, to assess the suitability of Linux to be such a platform, we evaluate the real-time performance of Xenomai-patched Linux on an ARM-based processor Exynos4210 with motion control applications. Experimental results show that it is possible to stably provide motion cycle times below lms to such applications even with background workloads.
