Abstract
A display controller reads blocks of data from a frame buffer and stores them in a local memory buffer of the display controller before outputting the blocks of data to a display. The display controller uses similarity meta-data associated with the output frame in the frame buffer 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 of the display controller 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 of the display controller, the display controller does not read a new data block from the frame buffer but instead provides the existing data block in its buffer to the display.
