PURPOSE:To plot a picture at a high speed by a simple circuit with respect to the method where graphic data generated by a graphic processor is inputted to a picture plotting register and is plotted in a frame memory. CONSTITUTION:In a picture plotting control part 2 which plots plural graphic data in a frame memory 3 after storing graphic data in plural picture plotting registers 20, each picture plotting register 20 to which graphic data is inputted is constituted by connecting plural same registers 200 in series, or a first in first out register(FIFO) is provided in the preceding stage of plural picture plotting registers 20, or the input from a graphic processor 1 is constituted by one FIFO. Data consisting of select bits to select plural picture plotting registers 20 is inserted to graphic data and following graphic data is inputted to plural picture description registers 20 in accordance with select bits of data, or a response signal is suppressed to stop the input of next graphic data when each picture description register 20 which has plural same registers 200 connected in many stages is full of data in respective stages. |
