Performance Analysis of Real Time Dynamic Scheduling Algorithms

Nothing has changed the world around us the way digital technology and computers have. Computers have entered every aspect of our life and the environment around us. Real time systems are playing vital role in daily life. In just a few decades ago, real time systems are reshaping the way people live, work, and play. Real time systems come in an endless variety of types, each exhibiting unique characteristics. For example, most vehicles driven today embed intelligent computer chips that perform value-added tasks, which make the vehicles easier, cleaner, and more fun to drive. Even private homes are being filled with intelligent appliances, which facilitate and enhance everyday life. Real- Time systems span several domains of computer science. They are defense and space systems, networked multimedia systems, embedded automotive electronics etc. The purpose of this chapter is to give an overview of the broad area of real-time systems. This task daunting because Real time systems areeverywhere and yet no generally accepted definition differentiates real-time systems from non-real-time systems.
