Abstract: In an embodiment, a system on a chip (SOC) includes a component that remains powered when the remainder of the SOC is powered off. The component may include a sensor capture unit to capture data from various device sensors, and may filter the captured sensor data. Responsive to the filtering, the component may wake up the remainder of the SOC to permit the processing. The component may store programmable configuration data, matching the state at the time the SOC was most recently powered down, for the other components of the SOC, in order to reprogram them after wakeup. In some embodiments, the component may be configured to wake up the memory controller within the SOC and the path to the memory controller, in order to write the data to memory. The remainder of the SOC may remain powered down.

Abstract: A user interface unit in a graphics processing display pipe may include registers programmable with information that defines active regions of an image frame. Pixels within the active regions of the image frame are meant to be displayed, while pixels outside of the active regions of the image frame are not to be displayed. Fetch circuitry within the user interface unit may fetch frames from memory, fetching only the pixels within the active regions of the image frames as defined by the programmed contents of the registers. The user interface unit may then provide the fetched pixels to a blend unit to blend the fetched pixels with pixels from other frames or pixels of a video stream to produce output frames. When blended with pixels of a video stream, the fetched pixels may be displayed as a graphics overlay on top of the video stream.

Abstract: Various techniques are provided for processing image data acquired using a digital image sensor 90. In accordance with aspects of the present disclosure, one such technique may relate to the processing of image data in a system 10 that supports multiple image sensors 90. In one embodiment, the image processing system 32 may include control circuitry configured to determine whether a device is operating in a single sensor mode (one active sensor) or a dual sensor mode (two active sensors). When operating in the single sensor mode, data may be provided directly to a front-end pixel processing unit 80 from the sensor interface of the active sensor. When operating in a dual sensor mode, the image frames from the first and second sensors 90a, 90b are provided to the front-end pixel processing unit 80 in an interleaved manner. For instance, in one embodiment, the image frames from the first and second sensors 90a, 90b are written to a memory 108, and then read out to the front-end pixel processing unit 80 in an interleaved manner.

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: Methods and apparatus for caching reference data in a block processing pipeline. A cache may be implemented to which reference data corresponding to motion vectors for blocks being processed in the pipeline may be prefetched from memory. Prefetches for the motion vectors may be initiated one or more stages prior to a processing stage. Cache tags for the cache may be defined by the motion vectors. When a motion vector is received, the tags can be checked to determine if there are cache block(s) corresponding to the vector (cache hits) in the cache. Upon a cache miss, a cache block in the cache is selected according to a replacement policy, the respective tag is updated, and a prefetch (e.g., via DMA) for the respective reference data is issued.

Abstract: A method of operating a media player is provided. In one embodiment the method includes receiving a plurality of initially configured video settings for viewing a video segment on the media player for a desired playback duration. The method further includes determining power required to play the video segment based on the initial video settings and playing the video segment if the required power matches or is less than total power available to the media player. In another embodiment, the method may further include, if the required power exceeds the total power available to the media player, adjusting one or more of the initial video settings, either automatically or by user inputs, to reduce the power required to play the requested video segment for the desired playback duration.
