Abstract: This paper focuses on the analysis of a dynamic low power switching technique called assertive dynamic power management (AsDPM) on ARM based platforms. The availability of ready tasks during the execution of a program is random. The choice to when exactly a ready task is executed on certain processor and how many processors are required for the remaining tasks can save a significant amount of energy utilization. This paper focuses on the energy efficiency of AsDPM strategy for real-time tasks, which decides when exactly a ready task shall execute; thereby reducing the number of active processors, which eventually reduces energy consumption. We will analyze the energy gains resulting from the implementation of this AsDPM power strategy for different ARM based multiprocessor platforms (ARM1176JZF-S, CortexA9). Results show significant amounts of gains up to 60% for different execution conditions*.
