Most of the embedded systems have real-time requirements about the use of Real-Time Operating Systems able of satisfying the embedded system requirements. So, in embedded application where the real-time operating systems are noted are been called as the Real Time Embedded Operating Systems (REOS). Main features of that of real-time systems would be discussed with this paper. To get a big picture, the authors basically take a look at many structures and standards of REOS. Then, issues and techniques for different key topics which are been scheduling, synchronization, and memory management are been discussed. In this paper, they are presenting the new way to tackle the problem with the resource reservation abstraction and an appropriate model for schedulability analysis.
