Patent ID: 7262776

Claim:
A method for generating image data, the method comprising the acts of: (a) writing tile data for a tile of a new frame to one of two memory spaces by reference to a first logical buffer, the first logical buffer providing a first association for each of a plurality of tiles to one of the two memory spaces; (b) concurrently with the act of writing, scanning out tile data for a current frame from one of the two memory spaces by reference to a second logical buffer, the second logical buffer providing a second association for each of the plurality of tiles to one of the two memory spaces; (c) receiving a frame flip signal; and (d) in response to the frame flip signal, copying the first logical buffer to the second logical buffer by modifying the second tile associations to match the first tile associations so that the first and second tile associations each concurrently reference a same one of the two memory spaces.
