Abstract: A power consumption measurement method for operating an electronic component during an interval of time includes: logging power states that the component adopts during the interval, interrogating the log to determine the amount of time that the component spent in each power state during interval, and multiplying the rated power consumption for each state by the amount of time spent in each respective state. The power consumptions for each of the states are summed to determine a total power consumption of the component during the interval. Logging the power states may be achieved by counting command line instructions of different types, thus identify the beginning and end of each power state, during the interval. The method may be used to measure and/or benchmark the actual power consumption of a DDR RAM module. An apparatus for carrying out the method is also disclosed.
