摘要： Examples are disclosed for an integrated circuit (IC) device coupled to a battery-operated power supply unit, such as an IC in a mobile computing device or wireless phone, to accurately determine energy usage drawn from the power supply unit under rapidly dynamic circumstances. A current sense signal of a power line from the power supply unit is digitized. The digitized current sense is added to an accumulator at a rate that is approximately proportional to a voltage of the power line from the power supply unit. The accumulator is then outputted and scaled to units relevant to energy measurements. The energy measurement is used to estimate remaining battery life. Triggering the digitization of the current sense signal may be by use of a pulse generation circuit, or by use of an overflow indicator of an accumulator for a digitized voltage sense signal. Other examples are described and claimed.

摘要： In an embodiment, a processor includes a power control unit and a plurality of components. A first component of the plurality of components is to receive a power input from a power supply device. The power control unit is to: determine a received voltage at a power input terminal of the first component; determine a voltage difference between the received voltage of the first component and a reliability goal voltage of the first component; determine a running average value based on the voltage difference; and adjust a supply voltage of the power supply device based on the running average value. Other embodiments are described and claimed.

摘要： Methods and apparatus relating to autonomous C state mechanism and computational engine alignment for improved processor power efficiency are described. An embodiment determines whether a semiconductor package should enter a package C state based on energy consumption values for entry into and exit from the package C state, an amount of time the semiconductor package stayed in the package C state previously, and one or more breakeven time points between the various package C states. Another embodiment detects a delay by an imaging computational unit of a processor to enter a low power consumption state relative to one or more other computational units of the processor. The logic causes the imaging computational unit to enter the low power consumption state in response to detection of the delay. Other embodiments are also disclosed and claimed.
