    Abstract: A system and method for determining power-performance state transition thresholds in a computing system. A processor comprises several functional blocks and a power manager. Each of the functional blocks produces data corresponding to an activity level associated with the respective functional block. The power manager determines activity levels of the functional blocks and compares the activity level of a given functional block to a threshold to determine if a power-performance state (P-state) transition is indicated. The threshold is determined in part on a current P-state of the given functional block. When the current P-state of the given functional block is relatively high, the threshold activity level to transition to a higher P-state is higher than it would be if the current P-state were relatively low. The power manager is further configured to determine the thresholds based in part on one or more of a type of circuit being monitored and a type of workload being executed.

    Abstract: A processing system detects user activities on one or more processing units. In response, an operating point (operating frequency or an operating voltage) of the processing unit handing the user activity is increased at the processing unit. Battery power may be conserved in some processing systems by limiting the increase in the operating point to a time interval and reducing the operating frequency or the operating voltage to a previous value after the time interval has elapsed.

    Abstract: An apparatus and method for efficiently managing balanced performance among replicated partitions of an integrated circuit despite loss of functionality due to manufacturing defects. A processing unit includes at least two replicated partitions, each assigned to operation parameters of a respective power domain. The partitions include multiple compute units. The compute units include multiple lanes of execution. Due to a variety of types of manufacturing defects, one or more of the partitions of the processing unit has less than a predetermined number of operational compute units. To balance the throughput of the multiple partitions, a power manager generates both static and dynamic scaling factors based on at least the corresponding number of operational compute units. Using these scaling factors, the power manager adjusts the operation parameters of power domains for the partitions relative to one another.

    Abstract: A method is provided for allocating power to compute units based on energy efficiency. Some embodiments of the method include allocating portions of a power budget of a system-on-a-chip (SOC) to a plurality of compute units implemented on the SOC based on ratios of a performance level for each compute unit to a power consumed by the compute unit operating at the performance level. An SOC is provided that includes a plurality of compute units and a power management controller to allocate portions of a power budget of the SOC to the plurality of compute units based on ratios of a performance level for each compute unit to a power consumed by the compute unit operating at the performance level.

    Abstract: An apparatus and method for dynamically adjusting power limits for processing nodes and other components, such as peripheral interfaces, is disclosed. The apparatus includes multiple processing nodes and other components, and further includes a power management unit configured to set a first frequency limit for at least one of the processing nodes responsive to receiving an indication of a first detected temperature greater than a first temperature threshold. Initial power limits are set below guard-band power limits for components that do not have reliable reporting of power consumption or for cost or power saving reasons. The amount of throttling of processing nodes is used to adjust the power limits for the processing nodes and these components.

    Abstract: Systems, apparatuses, and methods for implementing efficient power optimization in a computing system are disclosed. A system management unit records operating frequencies required for a computing component to execute a first task. The system management unit stores the recorded operating frequencies in a data array or any other predetermined memory location of a computing system. The system management unit uses the recorded operating frequencies to determine operating frequencies for execution of one or more other tasks.
