Embedded Systems are usually microcontroller-based systems that represent a class of reliable and dependable dedicated computer systems designed for specific purposes. Micro-controllers are used in most electronic devices in an endless variety of ways. Some micro-controller-based embedded systems are required to respond to external events in the shortest possible time and such systems are known as realtime embedded systems. So in multitasking system there is a need of task Scheduling, there are various scheduling algorithms like Fixed priority Scheduling (FPS), Earliest deadline first (EDF), Rate Monotonic(RM), Deadline Monotonic(DM), etc have been researched. In this Report various conventional algorithms have been reviewed and analyzed, these algorithms consists of single shape task, A new Multishape task scheduling algorithms has been proposed , implemented and analyzed.
