Description
Summary:Real-Time Executive for Multiprocessor Systems (RTEMS) is an open-source real-time operating system (RTOS) that is widely used in commercial and free embedded applications with notable adoption in space flight software and scientific instrument control for space science and high energy physics. RTEMS has rich support for POSIX environments and supports multiple POSIX and BSD file systems, along with some custom file systems designed specifically to meet the needs of real-time and embedded applications storage and retrieval of data. The range of file systems available in RTEMS motivates this study that investigates the salient features of each file system to help identify strengths and weaknesses with respect to application requirements and constraints. In this paper, we provide a comparison of the available RTEMS file systems and present some performance benchmarking results.
