Abstract Today numerous appliances like digital camera, laser printers, mobile phones and microwave ovens etc are powered by something beneath the sheath that makes them to do what they do. These tiny microcontrollers, working on basic assembly languages and high level languages are the heart of the appliances called Embedded Systems. An RTOS is responsible for managing the resources and hosting the applications that run on the embedded system but is designed specially to run with very precise timing and a high degree of reliability. The objective of this study is to design a simulator for real time embedded system software in stochastic environment. A comparative study is then made in terms of waiting and turnaround times for a number of processes based on two cases of priority scheduling policies used to design the simulator. The policy with minimum of these two parameters is considered the better one. Top Keywords Embedded System, RTOS, Priority Scheduling, Waiting time, Turnaround time. Top |
