Intel® Power Gadget 2.0 can be associated with the Intel® Energy Checker SDK (Intel EC SDK). Used as an ESRV* DAQ module**, the Intel® Power Gadget can provide processor average power (Watt), cumulative energy consumed (Joule) and instantaneous frequency (MHz) as counters. These counter’s values can then be read by any application using the SDK API or monitored with SDK tools.
THE GORY DETAILS
Let’s continue from where we left off last time. Let’s figure out the why of the equation,
P = C * V^2 * (a * f)
To do this, we’re going to have to look at what is going on in one of the fundamental building
blocks (a CMOS inverter) of an integrated circuit (IC).
So when and how does this circuit dissipate power?
