Abstract
PURPOSE:To enable to write-in with shift in bit unit, by shifting the data outputted from pattern ROM, dividing the data into two in response to the amount of shift, and writing in the front and rear sections into disply RAM twice. CONSTITUTION:The readout data from the pattern ROM10 is inputted to the 8 sets of shift registers 12a-12h, and the data are shifted by selecting the input signal. The data shifted in bit unit are divided into the front and rear sections, and written in the display RAMs 6a-6b twice. The data is read out at the readout mode with the H4 clock signal and after being inputted to the parallel-serial conversion circuits 7a-7c, it is converted into serial signal and outputted. This signal is converted into color video signal at the color conversion ROM22.
