Saving power when in or transitioning to a static mode of a processor

摘要

A method for reducing power utilized by a processor including the steps of determining that a processor is transitioning from a computing mode to a mode is which system clock to the processor is disabled, and reducing core voltage to the processor to a value sufficient to maintain state during the mode in which system clock is disabled.

1. A method comprising:
transitioning a processor to a reduced operation mode within a variable time allowed that varies based on a processor configuration; and reducing a voltage to the processor by a value dependent on the variable time allowed, wherein the voltage reduced by the value varies with a variation in the voltage and is sufficient to retain a memory state of the processor while the processor operates in the reduced operation mode.
