  • Power gating of cores by an SoC
    Patent number: 8850236
    Abstract: A method for power gating a core by a SoC is provided. Instruction Pointer information, state of the core, core access information and wake up latency information of the core are used in power gating or un-gating of the core. A change in state of the core is detected by a device driver and is provided to a power management unit. As the state of the core changes from active to passive, the wake up latency information and the core access information of the core are retrieved by the SoC from a database to perform either the power gating or the un-gating of the core. The database is prepared by analyzing code blocks statically.
