Abstract
A method includes fetching first synthesized pixels from an update buffer of a memory and fetching data pixels from an image buffer of the memory during the first drive frame period. Respective data pixels are fetched synchronously with the fetching of corresponding first synthesized pixels. Respective data pixels fetched from the image buffer are synthesized with corresponding first synthesized pixels to generate second synthesized pixels. The second synthesized pixels are stored in the update buffer during the first drive frame period. The storing of second synthesized pixels may be paused based on a prediction that the fetching of first synthesized pixels will not complete within the first drive frame period. The fetching of data pixels from the image buffer of the memory may also be paused based on the prediction that the fetching of first synthesized pixels will not complete within the first drive frame period.
