Abstract
PURPOSE: To perform character display processing through high-speed conversion after storing character display information in a skew state while employing word selection memory constitution for a buffer memory where the output of a character generator is set.
CONSTITUTION: Once a character code is indicated by host date processor 1, charactor display information that corresponds to the character code is set in buffer memory 5. The contents of buffer memory 5 are converted on the basis of lateral- writing and longitudinal-writing display mode information and they are read out and transferred to display unit 2. For example, when bit information bi is read out, value (i) is applied as address information ADRS and mode information MODE is set to logic "0", thereby reading the information. To read bit information b-j, value 2 is supplied when bit information b2j resides in memory 8-0 as address information and the mode information is set to logic "1", reading the information.
