Abstract: Computational resources of an electronic computer are monitored by predictors that establish predicted trade-offs between performance and power for a particular workload while the workload is being executed. A coordinator combines prediction values to identify a limited number of combinations of operating states of the computational resources, allowing operating states of the computational resources to be readily adapted during program execution based on a particular workload. The limited number of combinations of operating states are ideally Pareto optimal combinations.

Abstract: A system including a bus and a plurality of devices coupled thereto and configured to communicate with each other via the bus. The system further includes a power supply coupled to the bus, to power to the plurality of devices via the bus and to detect an event, and in response, alternately supply power to the plurality of devices via the bus at a first current level or at a lesser second current level. This allows additional devices to be used on a bus, even where the total power consumption of the devices would normally exceed a maximum defined by a bus architecture. This also helps allow a single gauge of wire to be used throughout a bus network (even where long lengths of wire are required) while still providing sufficient power to the devices connected to the bus.

Abstract: Power savings is provided to users of various electronic devices by monitoring the times and locations at which those users activate, deactivate, or otherwise change an operational state of one or more functional elements of a device. Other contextual or environmental information can be captured as well when the user performs such an action. One or more statistical analysis or prediction algorithms can be used to determine when and/or where the user is likely to repeat the one or more actions, where a confidence level of the prediction can be impacted at least in part by the environmental and contextual factors. When a prediction has a minimum level of confidence, a corresponding action can be performed automatically by the device when the relevant factors are met. Changes in behavior can be monitored such that the predictions can be refined over time.
