ABSTRACT:
A system has circuitry for reading out a graphic data string from a source area of a graphic memory, starting from a start address storing the graphic data string, by continuously counting the start address of the graphic memory. The graphic data string read out by this circuitry is stored in a buffer memory. When storage of the graphic data string in the buffer memory is completed, the graphic data string is continuously read out from the buffer memory. The readout graphic data string is written in a destination area, starting from a start address thereof, by continuously counting the start address of the destination area in the graphic memory.
