58 2. Power models
61 The power API registration functions provide a simple power model for
62 CPUs. The current power is calculated as dynamic power (static power isn't
63 supported currently). This power model requires that the operating-points of
70 The dynamic power consumption of a processor depends on many factors.
73 - The time the processor spends running, consuming dynamic power, as
74 compared to the time in idle states where dynamic consumption is
76 - The voltage and frequency levels as a result of DVFS. The DVFS
77 level is a dominant factor governing power consumption.
78 - In running time the 'execution' behaviour (instruction types, memory
83 A high level dynamic power consumption model may then be represented as::
91 The detailed behaviour for f(run) could be modelled on-line. However,
92 in practice, such an on-line model has dependencies on a number of
95 represented as a constant coefficient. This is a simplification
96 consistent with the relative contribution to overall power variation.
