An energy profiling apparatus for profiling power consumption characteristics of code being executed at an integrated circuit being powered by a power source and having a measurement module, a data processing module and a display module is disclosed. The energy profiling apparatus comprises first, second and third interfaces as well as a profile module. The first interface is configured to receive a first data set from the measurement module. The second interface is configured to receive a second data set from the data processing module. The third interface is configured to transmit a third data set to the display module. The profile module is configured to generate an energy profile of the code executed at the data processing module based on a correlation between the first data set and the second data set. Furthermore, the profile module is configured to transmit the energy profile as part of the third data set to the display module.
