Abstract
A processing system has a backlog of data caused by a difference between an input rate for receiving pixel data and a conversion rate for converting the pixel data to new pixel data. A dual buffer system associated with the processing system stores a minimum amount of unprocessed pixel data, required to perform an associated processing operation, in a first memory device and stores a backlog of the processed pixel data, after performing the associated processing operation, in a second memory device. The combined size of the first and second memory devices is less than the size that would otherwise be required to store the minimum amount of pixel data and the backlog of pixel data as unprocessed pixel data.
