Performance Analysis of Open-Source Real Time Operating Systems

This paper presents the importance of analysis and evaluation of Performance Metrics of Real Time Operating systems. Advanced parameters such as Semaphore Shuffling Time, Deadlock Breaking Time, TaskTask message Passing Time are considered in this paper. A 32-bit Microcontroller is chosen for benchmarking. Two RTOS that are available as open source for educational purpose are considered. Index ...

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 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...

Basic concepts of real-time operating systems

To most people, embedded systems are not recognizable as computers. Instead, they are hidden inside everyday objects that surround us and help us in our lives. Embedded systems typically do not interface with the outside world through familiar personal computer interface devices such as a mouse, keyboard and graphic user interface. Instead, they interface with the outside world through unusual ...
