Title: Fixed and Dynamic Priority Scheduling for Embedded Systems
Author(s): Luminiţa Giurgiu               

Abstract: This paper discusses and demonstrates some aspects of task scheduling policy effects on embedded control systems. This problem is studied because almost all control algorithms are realized by computers and controllers are often implemented as one or several tasks on a microprocessor with a real time operating system. Embedded control systems are subject to limited computer resources that are in fact shared resources, for which the tasks compete. A priority based approach and a deadline based scheduling are confronted in order to establish advantages and disadvantages. The simulations are realised in the TrueTime MatLab toolbox environment.

Keywords: scheduling policy, computer based control, embedded systems.
