A Survey of Real-time Operating Systems
ثبت نشده
چکیده
A real-time operating system (RTOS) supports real-time applications and embedded systems. Real-time applications have the requirement to meet task deadlines in addition to the logical correctness of the results. In this report, we review the pre-requisites for an RTOS to be POSIX 1003.1b compliant and discuss memory management and scheduling in RTOS. We survey the prominent commercial and research RTOSs and outline steps in system implementation with an RTOS. We select a popular commercial RTOS for each category of realtime application and discuss its real-time features. A comparison of the commercial RTOSs is also presented. We conclude by discussing the results of the survey and suggest future research directions in the field of RTOS.
