Open publisher page 64 citations

Abstract

The paper discusses the literature survey of RTOS (Real Time Operating Systems) and its contributions to the embedded world. RTOS is defined as a system in which the correctness of the system does not depend only on the logical results of computation but also on the time at which the results are produced. It has to perform critical tasks on priority basis keeping the context switching time minimum. It is often associated with few misconceptions & we have tried to throw some light on it. Since last 20 years, RTOS is undergoing continuous evolution and has resulted into development of many commercial RTOS products. We have selected few commercial RTOS of different 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.
