Abstract
Devices and methods method of tiled rendering are provided which comprises dividing a frame to be rendered, into a plurality of tiles, receiving commands to execute a plurality of subpasses of the tiles, interleaving execution of same subpasses of multiple tiles of the frame by executing one or more subpasses as skip operations, storing visibility data, for subsequently ordered subpasses of the tiles, at memory addresses allocated for data of corresponding adjacent tiles in a first direction of traversal and rendering the tiles for the subsequently ordered subpasses using the visibility data stored at the memory addresses allocated for corresponding adjacent tiles in a second direction of traversal, opposite the first direction of traversal.
