Consideration And Evolution Of Real Time Operating Systems: Rtos

This context deliberates the literature evolution of RTOS (Real Time Operating Systems) and its contributions to the embedded world. RTOS is is an operating system (OS) intended to serve real-time application process data as it comes in, typically without buffering delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter. An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS. It is often associated with few misconceptions & we have tried to throw some light on it. We have specified few commercial RTOS of uncommon categories of real-time applications and have discussed its real-time features. A comparison of the commercial RTOSs’ is presented. We conclude by discussing the results of the survey and comparing the RTOS based on performance parameters.This context deliberates the literature evolution of RTOS (Real Time Operating Systems) and its contributions to the embedded world.
