Active window and tile-based image processing systems and methods

Image processing circuitry comprising:

• active window assignment circuitry configured to determine a location of an active window within an image frame, the active window comprising a portion of the image frame to be processed by the image processing circuitry;
• tile assignment circuitry configured to determine locations of a plurality of tiles relative to the image frame based on the location of the active window, wherein an aggregate of the plurality of tiles encapsulates the active window;
• and
• memory-to-memory scaler and rotator (MSR) circuitry configured to:
• fetch respective portions of input image data corresponding to the plurality of tiles;
• and
• independently process each of the plurality of tiles to generate respective portions of processed image data.

A non-transitory, machine-readable medium comprising instructions, wherein, when executed by one or more processors, the instructions cause the one or more processors to control operations of image processing circuitry or to perform the operations, the operations comprising:

• determining a location of an active window within an image frame, the active window comprising a portion of the image frame to be processed;
• determining locations of a plurality of tiles relative to the image frame based on the location of the active window, wherein an aggregate of the plurality of tiles encapsulates the active window;
• fetching respective portions of input image data corresponding to the plurality of tiles;
• and
• independently processing each of the plurality of tiles to generate respective portions of processed image data.
