Udupi 1 E&C Engineering, GIT, Belgavi, India Software energy in an embedded system is the energy consumed while running the software. As the embedded system is expected to execute the task repeatedly, software energy is the major component in total energy consumption of an embedded system. For battery powered embedded applications, energy consumption estimation is very important. Different methods are available for software energy estimation. A simple method of software energy estimation with good accuracy is presented in this paper. Results are validated with micro benchmark programs. Accuracy of 2.01% to -5.83% is obtained for different micro benchmark programs. Also equation for instructions using immediate data is developed. R2 value of 0.9 is obtained. http://pubs.sciepub.com/jes/4/1/2/jes-4-1-2.pdf current measurement curve fitting embedded software energy consumption energy estimation
