Developing an environment for embedded software energy estimation

The paper presents the results of a novel method for the instruction-level energy consumption measurement and the corresponding modeling approach for embedded microprocessors. According to the proposed method the base and inter-instruction energy costs of the ARM7TDMI embedded processor as well as the energy cost due to different values in the instruction parameters are modeled. These models can be used in the estimation of the energy consumed by the processor to execute real software programs. A software tool has been developed to automate energy estimation.
