This paper presents the implementation of an Earliest Deadline First (EDF) based algorithm to support number of real time applications on a single processor. This algorithm overcomes the limitation of real-time algorithm in tracking the task and provides more controllability and predictability to dynamic algorithm. This algorithm is designed through basic theorem of EDF. The proposed algorithm is simulated for independent, preemptive and periodic tasks. The results obtained from simulation shows, that tracking of task at any desirable time instant is very effective. The same algorithm was implemented on development board MCB2140 and results were verified.
