Abstract
PURPOSE: To simplify the circuit constitution of a display signal generation system which inputs data by key input and supplies them to a display unit when input data are displayed, substituting hardware control with software control.
CONSTITUTION: Arithmetic part 5, including RAM, preforms the storage and arithmetic of various data to effect and control part 6, including ROM, exercises opration control according to the procedure of generating a digit assignment signal stored in ROM. When receiving digit assignment input signals DIn sent out in sequence according to RAM address assignment corresponding to digits of control part 6 from arithmetic part 5, digit-assignment signal generating part 7 generates digit assignment signals Dn by digit assignment set/reset signals DnSET/RESET from control part 6.
