Method and apparatus for a fast graphic rendering realization methodology using programmable sprite control

摘要

A technique for updating computer-graphic digital images comprises coding a position of pixels located in a foreground of a computer-graphic image frame; sending the coded positions of the pixels located in the foreground of the computer-graphic image frame to a frame buffer of a sprite controller; separating a background pixel group from a foreground pixel group in the computer-graphic image frame based on the coded positions; updating the pixels in the foreground pixel group only; and transmitting a frame number and a frame buffer parameter dimension corresponding to the updated pixels to a computer-graphic image display viewer.
