Abstract
Embodiments of a computing system that may monitor energy usage are disclosed. The embodiments may provide a low overhead method for determining energy usage of a given application or process. Circuitry is configured to determine a respective energy for each of the plurality of operations and sum each respective energy for at least some of the plurality of operations to generate a normalized total. The circuitry may be further configured to scale the normalized total to generate an energy value, and store the energy value in a register. System software may then read the energy value from the register and determine an energy usage for at least one application dependent upon the energy value.
