An Analysis Energy Consumption Tool for ARM7 Processor
Abstract
Estimations about energy consumption in embedded applications allow to engineers improve codification, scale power systems as well as improve redundant power system in case of fail. In this context, was developed a framework, which is capable to characterize execution time, requested power, used energy, executed instructions and its frequency. Additionally, the developed framework is capable to evaluate ARM processor and its operations modes like THUMB/ARM in terms of execution time and used energy. The framework was evaluated with five applications of benchmark Powerstone suite. Preliminaries results of these applications showed differences of 98% for execution time and approximately 73% in used energy when different operation modes are used.
