Abstract: A media processing system and device with improved power usage characteristics, improved audio functionality and improved media security is provided. Embodiments of the media processing system include an audio processing subsystem that operates independently of the host processor for long periods of time, allowing the host processor to enter a low power state while the audio data is being processed. Other aspects of the media processing system provide for enhanced audio effects such as mixing stored audio samples into real-time telephone audio. Still other aspects of the media processing system provide for improved media security due to the isolation of decrypted audio data from the host processor.

Abstract: Methods and apparatuses for dynamically budgeting power usage in a data processing system. In one aspect, a data processing system, includes: one or more first components capable of being dynamically throttled to a plurality of different performance level settings; one or more second components; and one or more power usage sensors. The one or more power usage sensors are to determine information on power usage during a first time period of operation of the data processing system. The one or more first components and the one or more second components may include a computing element to determine one of the performance level settings of the one or more first components of the data processing system for a second time period subsequent to the first time period using the information on the power usage during the first time period.

Abstract: A method and system is disclosed for accessing I/O and memory devices utilizing a DMA controller. Each device may be connected to the DMA controller through an individual channel. Clocking circuitry in the DMA may allow the DMA controller to send signals to each device at a prescribed frequency. Furthermore, the DMA controller is capable of activating and deactivating a channel clock, used in sending signals to the devices, based on the operational status of the individual devices. The DMA controller is also capable of tuning the channel clock dependant on the capabilities of any active devices. In this manner, the amount of bandwidth used during a DMA data transfer can be tailored to the specific requirements of the devices involved with the data transfer.

Abstract: An electronic device may have input-output ports. The electronic device may have control circuitry and input-output devices. The input-output devices may include sensors, camera equipment, and other input devices that the control circuitry uses to monitor the location of the plug relative to the input-output port. The input-output devices may also include a display, light-emitting diode array, speaker, or other visual or audio output device. The control circuitry can use the output device to provide a user with plug alignment assistance information. The plug alignment assistance information can be provided visually, using audio, or using other output. Plug alignment assistance information can include information that helps the user align the plug with a port and may be based on information on the location of the plug relative to the input-output ports and based on information on which ports are available.

Abstract: Exemplary embodiments of methods and apparatuses to provide a cooling arrangement for a system are described. The system includes a component coupled to a heat sink. A signal associated with a temperature control of the component is asserted. A target temperature of the heat sink is adjusted based on the signal. In one embodiment, a temperature control loop of the heat sink is operated. The temperature of the heat sink may be monitored using one or more sensors placed on the heat sink. An operation of the component, a cooling unit coupled to the heat sink, or both, may be adjusted based on a relationship between the temperature of the heat sink and an adjusted target temperature. Adjusting the target temperature of the heat sink based on the asserted signal increases efficiency of the system while decreasing cooling.
