+title: Qualcomm Core Power Reduction v3/v4/Hardened (CPR3, CPR4, CPRh)
+
+description:
+ CPR (Core Power Reduction) is a technology to reduce core power of a CPU
+ (or another device). Each OPP of a device corresponds to a "corner" that
+ has a range of valid voltages for a particular frequency.
+ The CPR monitors dynamic factors such as temperature, etc. and suggests
+ or (in the CPR-hardened case) applies voltage adjustments to save power
+ and meet silicon characteristic requirements for a given chip unit.
