Method and apparatus for managing global chip power on a multicore system on chip

A method for controlling power consumption, the method comprising:

• accumulating one or more power estimates associated with multiple core processors based on a configuration, the multiple core processors arranged in the configuration;
• determining a cumulative power estimate based at least in part on the one or more power estimates accumulated;
• determining a global power threshold based on the cumulative power estimate determined;
• and
• causing power consumption at each core processor to be controlled based on the global power threshold determined.

An apparatus comprising:

• means for accumulating one or more power estimates associated with multiple core processors based on a configuration, the multiple core processors arranged in the configuration;
• means for determining a cumulative power estimate based at least in part on the one or more power estimates accumulated;
• means for determining a global power threshold based on the cumulative power estimate determined;
• and
• means for causing power consumption at one or more of the multiple core processors to be controlled based on the global power threshold determined.
