摘要： A power controller can set the power state of a processor bridge based on which processor modules are in a communicative state. In addition, for a power state where selected processor modules are expected to be non-communicative, the power controller can set the supplied voltage to have a reduced voltage guard band as compared to other power states. These power management techniques can reduce the power consumed by the processor.

摘要： A system and method for efficient management of resources within a semiconductor chip for an optimal combination of power reduction and high performance. An intergrated circuit, such as a system on a chip (SOC), includes at least two processing units. The second processing unit includes a cache. The SOC includes a power management unit (PMU) that determines whether a first activity level for the first processing unit is above a first threshold and a second activity level for the second processing unit is below a second threshold. If this condition is true, then the PMU places a limit on a highest power-performance state (P-state) used by the second processing unit. The PMU sends an indication to flush the at least one cache within the second processing unit. The PMU changes a P-state used by the first processing unit to a higher performance P-state.

摘要： A system may comprise a plurality of processing units and a scheduler configured to maintain a record for each respective processing unit. Each respective record may comprise entries which may indicate 1) how long the respective processing unit has been residing in an idle state, 2) a present power-state in which the respective processing unit resides, and 3) whether the respective processing unit is a designated default (bootstrap) processing unit. The scheduler may select one or more of the plurality of processing units according to their respective records, and assign impending instructions to be executed on the selected one or more processing units. Where additional processing units are required, the scheduler may also insert an instruction to trigger an inter-processor interrupt to transition one or more processing units out of idle-state. The scheduler may then assign some impending instructions to these one or more processing units.

摘要： A method and apparatus for dynamically controlling a cache size is disclosed. In one embodiment, a method includes changing an operating point of a processor from a first operating point to a second operating point, and selectively removing power from one or more ways of a cache memory responsive to changing the operating point. The method further includes processing one or more instructions in the processor subsequent to removing power from the one or more ways of the cache memory, wherein said processing includes accessing one or more ways of the cache memory from which power was not removed.

摘要： A method for power management is disclosed. The method may include monitoring requests for access to a memory of a memory subsystem by one or more processor cores; and monitoring requests for access to the memory conveyed by an input/output (I/O) unit. The method may further include determining if at least a first amount of time has elapsed since any one of the processor cores has asserted a memory access request and determining if at least a second amount of time has elapsed since the I/O unit has conveyed a memory access request. A first signal may be asserted if the first and second amounts of time have elapsed. A memory subsystem may be transitioned from operating in a full power state to a first low power state responsive to assertion of the first signal.
