Data Structures, Methods and Tiling Engines for Storing Tiling Information in a Graphics Processing System

Abstract: a control stream decoder decodes a control stream for a tile group comprising at least two tiles of a rendering space. a primitive block entry analyser received a primitive block entry of the control stream and identifies a location in memory of a control data block for a corresponding primitive block. for the received primitive block entry, in response to determining that a current tile is a valid tile for the corresponding primitive block, the control data block for the corresponding primitive block is retrieved from the identified location in memory. an address of the corresponding primitive block in memory is identified from the control data block and primitives of that primitive block relevant for rendering the current tile, and information identifying the address of the corresponding primitive block and the primitives of that primitive block relevant for rendering the current tile is outputted.
