  • Optimization of image processing using multiple processing units
    Patent number: 8509569
    Abstract: Some embodiments provide an image editing application that utilizes at least two processing units to efficiently process an image with multiple effects after at least one of the effects modified from the image. Some such embodiments maintain a queue for identifying each of the effects to reprocess. Some embodiments determine a modified ordering for the effects in the queue based on criteria that is related to reducing data exchanges between the processing units when applying the effects. From the modified ordering, a first processing unit applies a first set of the effects before passing resulting data to a second processing unit for application of a second set of the effects. The second processing unit applies a second set of effects to produce the image with the multiple effects and the at least one effect removed or modified.
