Abstract: The present invention discloses an apparatus and method for bitmapping and synchronization. The present invention increases the serial number of a graphic command issued by a CPU. A page number of a display memory bitmapping to a graphic commands and a serial number of the graphic command are stored in a system memory connected to a CPU. The CPU directly accesses the display memory until the serial number corresponding to the page number stored in the page info equal to the page number of the graphic command issued currently by the CPU is less than the serial number of the graphic command executed currently by the graphic accelerator and the problem of data inconsistency could be neglected.
