A dynamic scheduler is provided that schedules tasks for a plurality of cores based upon current operating characteristics for the cores. The current operating characteristics include a predicted leakage current for each core based upon an analytical model.

Multi-core dynamic workload management using native and dynamic parameters

Exemplary embodiment of a device is disclosed comprising a processor to provide instructions, a first voltage regulator in communication with the processor to receive provided instructions received from the processor and to dynamically modulate an output voltage based on the received instructions, and a plurality of second voltage regulators to receive the output voltage from the first regulator; the output voltage to reduce a cross-regulation interference between the second regulators due to a change in a load of at least one of the second voltage regulators.

Reducing cross-regulation interferences between voltage regulators

System(s) and method(s) are provided for dynamically scaling switching frequencies and clock sources of switched mode power supplies (SMPSs) in a mobile station. Switching frequency is scaled to an optimal value in response to at least one of (i) a change in mode of operation for wireless communication employed by the mobile station, an additional mode of operation is triggered, (ii) a change in operation conditions of a set of loads associated with functionality of the mobile is determined, or (iii) an LO spur set-off by a SMPS in the presence of an interference signal with a frequency splitting from an operational band that matches the SMPS frequency or at least one of its harmonics. Switching frequencies can be selected from a lookup table, or through an analysis of switching frequencies available to the mobile and operational criteria. A set of clock sources can provide an ensemble of switching frequencies.
