Abstract :
In this paper, we present few energy-cognizant algorithms using slack reclamation method. In the present design, the Earliest-Deadline-First (EDF) scheduling policies have been employed on the both CPUs for the dynamic tasks and FIFO scheduling for static tasks. When a new task arrives and the primary processor is active then that task will be scheduled in secondary if that processor is inactive else based on priority context switching will happen. The proposed System shows significant energy saving compared to existing SSPT algorithms.
