Abstract
PURPOSE: To shorten a processing time to improve the processing capability of display control by setting the read start address of a screen buffer to an arbitrary address by a microprocessor.
CONSTITUTION: The value of register 30 is set to A by microprocessor 41, and simultaneously, the value of this register 30 is transferred to address counter 31. Next, the value of counter 31 is counted up in order of A, A+n, A+2n,...A+23h, and simultaneously, read start addresses of screen buffer 10 based on these values are set to arbitrary addresses from memory 42 to write data codes. These data codes are converted to dot patterns successively by character generator 43 and are subjected to parallel-series conversion by parallel-series converter 44 and are displayed on display equipment 20'. As a result, the processing time can be shortened to improve the processing capability of display control.
