Abstract:
1. A computer performed method of measuring a power consumption indicator over an arbitrary interval in an electronic system, comprising: accumulating counts of values of said power consumption indicator at a predetermined rate in corresponding ones of a plurality of storage locations of a computer system corresponding to a histogram, wherein said power consumption indicator is a measured power consumption value or a power consumption mode value for said electronic system; first reading a first histogram data set from said storage locations at a beginning of said arbitrary interval; second reading a second histogram data set from said storage locations at an end of said arbitrary interval; subtracting said first histogram data set from said second histogram data set to form an interval difference histogram; and displaying results determined in conformity with a result of said subtracting or performing power control within said electronic system in conformity with a result of said subtracting.
