A computer system having multiple graphics controllers configured to share graphics and video functions, including each executing a portion of a single block transform "BLT" operation in parallel to transfer a block of pixel data from a source to a destination on a graphics surface; and multiple local memories connected to the graphics controllers and configured to store pixel data of a source in a designated pattern allocated to different graphics controllers, wherein each includes a scratch pad for storing, upon request to execute a single BLT operation, all pixel data of the source that are in regions controlled by another graphics controller and copied from the other local memory.
