Processor is an important computing element in portable battery operated real time embedded system and it consumes most of the battery energy. Energy consumption, processor memory space are considered as basic design constraints in ARM based system and heuristic algorithm is developed for energy consumption as well as memory space management. This algorithm includes rate monotonic fixed priority task scheduling scheme, DVS, ARM's normal/thumb mode, execution time, and number of execution cycles, which are analytically related with energy consumption.
