PURPOSE:To shorten the writing time and to increase the picture processing speed by writing simultaneously the same picture data or the same control data not in the order of R, G and B units. CONSTITUTION:When the picture data are written into an R picture memory 2, a G picture memory 3, and a B picture memory 4, a picture data R/W circuit 7 writes the picture data received via a picture data line 5 into an address designated by an address line 6. A write grant signal is transmitted when two or all of R, G and B have the same data. Thus the gates of write circuits 8-10 are turned on and the write signals are simultaneously outputted to the memories 2-4. As a result, the picture data on the line 5 are written into the memories 2-4 and then outputted to a D/A conversion control circuits 11-13. Then the control data are written at one time. |
