Mobile software is often deployed on processors with limited energy. Energy consumption has been an important quality attribute to evaluate such software. Compared with the code level and instruction level assessment, energy consumption assessment at design level has the advantages of low time consumption and low cost. In recent years, it has become a research focus in academic and industrial fields of software engineering. Currently, most of the methods on energy consumption evaluation did not evaluate the energy consumption of internal behavioral elements of software components, resulting in the problem of low precision. To tackle this problem, this study builds a model of energy consumption evaluation for mobile software based on AADL language and the StrongARM processor. Further, a process for evaluating energy consumption of mobile software is defined based on AADL language. In addition, a tool for evaluating energy consumption is developed. Lastly, a method for evaluating the energy consumption of mobile software is proposed based on AADL language. The experimental results show that the proposed method improves precision compared with existing evaluation method of energy consumption based on AADL.
