<p>A display controller 7 reads blocks of data from a frame buffer 3 and stores them in a local memory buffer 8 of the display controller 7 before outputting the blocks of data to a display The display controller 7 uses similarity meta-data 10 associated with the output frame in the frame buffer 3 to determine whether a new block of data to be processed for display is similar to a block of data already stored in the local memory 8 of the display controller 7 or not. If it is determined that the data block to be processed is similar to a data block already stored in the local buffer 8 of the display controller 7, the display controller does not read a new data block from the frame buffer 3 but instead provides the existing data block in its buffer 8 to the display 2.</p> |
