    Abstract: Some embodiments of the invention include an apparatus and method for dynamically choosing an optimum power state. In some embodiments, the optimum power state may be determined from historical information about the various power states that any of the embodiments of the apparatus or a system equipped with embodiments of the apparatus or operating embodiments of the method may encounter. Some embodiments may generate registers to maintain information regarding the various power states. In some embodiments, power management logic may determine the optimum power state based upon this information. Other embodiments are described.

    Abstract: A method and apparatus to retrieve data for a multiprocessor system is described. A request for data is received at a first processor from a bus. A cache is searched for the data, with the data having a state. A determination is made as to whether the state is an exclusive state or shared state. The data is sent to the bus in accordance with the determination.

    Abstract: Embodiments of the invention relate to energy efficient and conserving thermal throttling of electronic device processors using a zero voltage processor state. For example, a processor die may include a power control unit (PCU), and an execution unit having power gates and a thermal sensor. The PCU is attached to the thermal sensor to determine if a temperature of the execution unit has increased to greater than an upper threshold, such as while the execution unit is processing data in an active processor power state. The PCU is also attached to the power gates so that upon such detection, it can change the active processor power state to a zero processor power state to reduce the temperature of the execution unit. When the sensor detects that the temperature has decreased to less than a lower threshold, the PCU can change the processor power state back to the active state.
