Abstract:
A method of managing display data involves maintaining caches ( 25, 29 ) of most recently used tiles of display data at a host ( 21 ) and at a display control device ( 22 ). The caches ( 25, 29 ) are synchronised so that they contain the same data in the same locations. When the host ( 21 ) generates a tile that needs encoding and transmitting, it checks to see if that tile is already stored in the host cache ( 25 ). If so, it sends a cache ID to the display control device ( 22 ); otherwise, it encodes and sends the tile. When the display control device ( 22 ) receives data, it identifies it either as a cache ID or as an encoded tile. If it is a cache ID, the data is retrieved from the display control device cache ( 29 ) and sent for display ( 23 ); otherwise, it decodes the tile and sends it for display ( 23 ). Both caches ( 25, 29 ) are updated so that the tile is indicated as the most recently accessed item in each cache ( 25, 29 ).

Claim (Index 12):
A method of managing display data, the method comprising, at a display control device:\n receiving from a host device, information regarding display data for a frame to be displayed on a display device controlled by the display control device, the frame of display data being divided into a plurality of tiles, where each tile is formed of display data for a plurality of pixels to be displayed in the display device as a single frame, wherein the information comprises, for each tile, either:\n a tile identification and an associated match identification for the tile, the tile identification including a location of the tile within the frame to be displayed and the match identification identifying a stored tile in a cache memory at the display control device and replicated in a cache memory at the host device; or \n the tile identification and the display data for the tile; \n wherein, if the information comprises the tile identification and an associated match identification for the tile, the method further comprising:\n identifying a stored tile in the cache memory from the associated match identification; \n retrieving display data of the stored tile from the cache memory or from a local memory based on a pointer retrieved from the cache memory; and \n controlling the display device to display the display data of the stored tile at the location in the tile identification; or \n if the information comprises the tile identification and the display data for the tile, the method further comprising:\n storing the display data of the tile in the cache memory as a stored tile or at a location in a local memory with a pointer to the location in the local memory being stored in the cache memory; and \n controlling the display device to display the display data at the location in controlling the display device to display the display data at the location in the tile identification.
