A Comprehensive Review on Functional Analysis of Real-Time Operating Systems

A real-time operating system (RTOS) is a system made to help us in real-time using real-time applications that provide no delay. A RTOS is time-bound, which means that time is the main part of the system, as the system will fail if it goes beyond the prescribed time. Processing the time requirements in this system are measured in tenths of seconds. The integrity of an RTOS system established not only takes the logical effects of computation into account but also the amount of time required to get such results. It must prioritize vital jobs while keeping context-switching time to a minimum. This research aims to perform a comprehensive functional analysis of real-time operating systems (RTOS), with a particular emphasis on key components such as interrupt handling strategies, synchronization mechanisms, and job scheduling algorithms. The purpose of the study is to shed light on the state of the art at the moment, point out roadblocks, and suggest possible enhancements for raising RTOS capability and performance in significant embedded systems.
