A Survey of Contemporary Real-time Operating Systems

A real-time operating system (RTOS) supports applications that must meet deadlines in addition to providing logically correct results. This paper reviews pre-requisites for an RTOS to be POSIX 1003.1b compliant and discusses 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 within each category of real-time 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. Povzetek: Podan je pregled operacijskih sistemov v realnem času.
