Abstract: A parallel multi-step power management flow apparatus and method for using the same are disclosed. In one embodiment, an integrated circuit comprises a plurality of processing entities to execute operations, a power controller coupled to the plurality of processing entities to control power management for the plurality of processing entities, and a plurality of agents, where each of the plurality of agents is operable to perform a power control flow for one of the processing entities by separately scheduling, using a scheduler, and executing a plurality of power control flow phases in response to a plurality of requests received from the power controller, and each agent is operable to send a plurality of acknowledgements, one acknowledgement for each phase, upon completion of the plurality of power control flow phases.

Abstract: In an embodiment, a processor includes a first core and a power management agent (PMA), coupled to the first core, to include a static table that stores a list of operations, and a plurality of columns each to specify a corresponding flow that includes a corresponding subset of the operations. Execution of each flow is associated with a corresponding state of the first core. The PMA includes a control register (CR) that includes a plurality of storage elements to receive one of a first value and a second value. The processor includes execution logic, responsive to a command to place the first core into a first state, to execute an operation of a first flow when a corresponding storage element stores the first value and to refrain from execution of an operation of the first flow when the corresponding element stores the second value. Other embodiments are described and claimed.

Abstract: A method and apparatus for providing power state information using in-band signaling are described. In one embodiment, an integrated circuit (IC) device comprises a controller operable to receive a command from a platform control bus, the command requesting data that is unrelated to information about a power state in which the IC resides; and control logic operable to obtain data for inclusion in a response to the command, wherein the controller is operable to send the response over a bus, the response containing at least a portion of the data responsive to the command and containing power state information for the IC.

Abstract: Methods and apparatus relating to autonomous C state mechanism and computational engine alignment for improved processor power efficiency. are described. An embodiment determines whether a semiconductor package should enter a package C state based on energy consumption values for entry into and exit from the package C state, an amount of time the semiconductor package stayed in the package C state previously, and one or more breakeven time points between the various package C states. Another embodiment detects a delay by an imaging computational unit of a processor to enter a low power consumption state relative to one or more other computational units of the processor. The logic causes the imaging computational unit to enter the low power consumption state in response to detection of the delay. Other embodiments are also disclosed and claimed.
