-QCOM CPR (Core Power Reduction)
-
-CPR (Core Power Reduction) is a technology to reduce core power on a CPU
-or other device. Each OPP of a device corresponds to a "corner" that has
-a range of valid voltages for a particular frequency. While the device is
-running at a particular frequency, CPR monitors dynamic factors such as
-temperature, etc. and suggests adjustments to the voltage to save power
-and meet silicon characteristic requirements.
