    摘要: In an embodiment, a processor includes a first processor core, a second processor core, a first voltage regulator to provide a first voltage to the first processor core with a first active value when the first processor core is active, and a second voltage regulator to provide a second voltage to the second processor core with a second active value when the second processor core is active. Responsive to a request to place the first processor core in a first low power state with an associated first low power voltage value, the first voltage regulator is to reduce the first voltage to a second low power voltage value that is less than the first low power voltage value, independent of the second voltage regulator. First data stored in a first register of the first processor core is retained at the second low power value. Other embodiments are described and claimed.
