Abstract :
In embedded systems, the frequent execution of software drives the activities of hardware, which causes the energy consumption of systems. In this paper, we first propose an improved C source-level code program energy model by considering the energy consumption of instruction fetching phase, in which a accurate energy algorithm is used. Then, we implement a method to dynamically calculate the run-time energy consumption between program breakpoints through GDB. The simulation experiment results show that, at the same condition, we can obtain the more accurate energy consumption values between program breakpoints flexibly through GDB, and this provides some conveniences for us to optimize the program energy consumption in the future.
