Abstract

PURPOSE: To make it possible to process a character code specified by n bits by connecting a gate circuit capable of supplying data to a 1st memory or a 2nd memory and switching the gate circuit based upon code data supplied from a central processing unit(CPU). CONSTITUTION: The CPU 1 sends 8-bit code data from its output terminal to a data bus 3, which is directly connected to the address terminal of a text video RAM 5 to be the 1st memory 3 and connected also the input terminal of the gate circuit 9. When a control signal supplied from a comparator group 7 is in a high level, the circuit 9 holds an OFF state, and when the control signal is in a low level, is turned to an ON state and supplies the code data appearing on the bus 3 to a text video RAM 11 to be the 2nd memory. Consequently a character code defined by n bits and a character code defined by the integer times of n bits is mixedly read out and a character code regulated by code data consisting of the integer times of n bits is processed.
