+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.
