A Survey on Different Real Time Operating Systems

A Survey of Real-time Operating Systems

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 resea...

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...

Real - Time Operating Systems

Real Time Operating Systems Overview ∗

Modern control systems applications are often built on top of a real time operating system (RTOS) which provides the necessary hardware abstraction as well as scheduling, networking and other services. Several open source RTOS solutions are publicly available, which is very attractive, both from an economic (no licensing fees) as well as from a technical (control over the source code) point of ...

A Real Time Operating Systems (RTOS) Comparison

This article presents quantitative and qualitative results obtained from the analysis of real time operating systems (RTOS). The studied systems were Windows CE, QNX Neutrino, VxWorks, Linux and RTAI-Linux, which are largely used in industrial and academic environments. Windows XP was also analysed, as a reference for conventional non-real-time operating system, since such systems are also comm...
