Dynamic table look-up based voltage regulator control |
摘要 |
A technique for dynamically controlling microprocessor power plane voltage levels includes storing in a memory on a voltage regulator voltage control identifiers in a table accessible according to performance state. In at least one embodiment of the invention, a method includes transitioning a voltage output of a voltage regulator to a next voltage level associated with a next performance state of a processor coupled to the voltage regulator based on a performance state indicator received from the processor and a corresponding entry of a performance state table. In at least one embodiment, the method includes loading performance state table entries into a storage device on the voltage regulator circuit. |
