The steadily increasing performance of mobile devices also implies a rise in power consumption. To counteract this trend it is mandatory to accomplish software power optimizations based on accurate power consumption models characterized for the processor. This paper presents an environment for automated instruction set characterization based on physical power measurements. Based on a detailed instruction set description a testbench generator creates all needed test programs for a complete characterization. Afterwards those programs are executed by the processor and the energy consumption is measured. For an accurate energy measurement a high performance sampling technique has been established, which can be either clock or energy driven.
