Abstract: The disclosed embodiments provide a system that transfers data from a storage device to a host. The system includes a communication mechanism that receives a request to read a set of blocks from the host. Next, upon reading each block from the set of blocks from the storage device, the communication mechanism transfers the block over an interface with the host. The system also includes an error-detection apparatus that performs error detection on the block upon reading the block, and an error-correction apparatus that performs error correction on the block if an error is detected in the block. The communication mechanism may then retransfer the block to the host after the error is removed from the block.

Abstract: A system and method is disclosed for efficiently managing power distribution among the various functional blocks used within portable electronic devices. The method includes allowing each functional block to be independently controlled, containing its own low-level software and power controls for setting the local power state of the functional block. For each power control domain in the implementation, hardware uses these local power states and determines and sets the actual operating state of the power control domain accordingly.

Abstract: Methods and apparatuses for dynamically budgeting power usage to control temperatures in a data processing system. In one aspect, a data processing system includes: a first sensor to determine an ambient temperature of an environment in which the data processing system is; and a controller (e.g., a microcontroller or a microprocessor) coupled to the sensor to control operations of the data processing system according to the ambient temperature. In one example, the data processing system further includes a second sensor to determine an actual temperature of a component of the data processing system. In one example, a controller is coupled to the temperature sensors to determine an operating setting of the data processing system based on a prediction of a temperature of the data processing system which is a function of the plurality of actual temperatures and the operating setting of the data processing system.

Abstract: A method and system is disclosed for passing data processed by a DMA controller through a transmission filter. The method includes the DMA controller accessing data for transfer between an origination location in the system and a destination location in the system. The accessed data is passed through the DMA controller before being sent to the destination location. While the data is being passed through the DMA controller, it is passed through a transmission filter for processing. This processing may include the addition or removal of transmission protocol headers and footers, and determination of the destination of the data. This processing may also include hash-based packet classification and checksum generation and checking. Upon completion of the processing, the data is sent directly to a prescribed destination location, typically either a memory circuit or an I/O device.

Abstract: Exemplary embodiments of methods and apparatuses to manage a power of a system that leverage intermediate power margins are described. One or more subsystems of the system are operated at one or more performance points. A power consumed by the one or more subsystems at each of the one or more performance points is measured. An operational power of the one or more subsystems at the one or more performance points is determined. The one or more subsystems are operated at well-known conditions at the one or more performance points. The operational power may be adjusted based on data associated with the one or more subsystems. The operational power is provided to a power lookup table. The power is distributed among the one or more subsystems based on the operational power.

Abstract: Exemplary embodiments of methods and apparatuses to dynamically redistribute power in a system that includes a plurality of subsystems are described. A load profile of the system is identified. The power is redistributed between the subsystems while tracking the load profile. The load profile may be an asymmetric, or a balanced load profile. The load profile is identified based on a utilization factor for each of the subsystems. In one embodiment, the power used by each of the subsystems is sensed by one or more sensors or predicted or estimated. A utilization factor, which may be a ratio of the actual power used by the subsystem to the power allocated to the subsystem, is calculated. The load profile is determined using the utilization factor of each of the subsystems. A power weighting arrangement between the subsystems, for example, a power distribution table, is selected based on the load profile.

Abstract: Exemplary embodiments of methods and apparatuses to manage a power of a data processing system are described. One or more constraint parameters of a system are monitored. The data processing system is forced into an idle state for a first portion of a time while allowed to operate for a second portion of the time based on the one or more constraint parameters, wherein the system is forced into the idle state in response to comparing a target idle time to an actual idle time. The target idle time of the system is determined, in one embodiment, based on the one or more constraint parameters. The actual idle time of the system may be monitored to take into account interrupts which disrupt an idle time and idle times resulting from no software instructions to execute. The system may be allowed to operate based on comparisons of the target idle time and the actual idle time.

Abstract: The disclosed embodiments provide a system that operates a processor in a multi-core processor system. During operation, the system detects the creation of an asynchronous wakeup event for the processor. In response to detecting the creation of the asynchronous wakeup event, when the processor is subsequently placed into an idle state, the system configures the processor to resume operation at a reduced frequency that is a fraction of an operating frequency for the multi-core processor system, wherein the reduced frequency allows more power to be allocated to other processors in the multi-core processor system.
