Energy-monitoring tool for low-power embedded programs

The development of the Seoul National University energy scanner (SES), an energy-monitoring tool for low-power embedded programs, is discussed. The three logical modules of the SES are listed as energy estimation, energy analysis and user interface. SES, which enables the users to identify potential energy hot spots in embedded programs, associates power consumption data with C program and assembly language source code. The power measurement circuitry, embedded in its board, cancels the need for any additional measurement equipment. The proposed power measurement technique and the energy-monitoring methodology of SES are platform independent.
