Abstract

PURPOSE: To simplify a circuit constitution by simplifying the wiring between a computer and this circuit and restraining the number of pulse generator circuits to one in the control circuit which displays processing results of the central arithmetic processing part with characters, symbols, or patterns.
CONSTITUTION: RAM 27 where character display data from address multiplexer 26 designated by horizontal and vertical address counters 23 and 25 is stored and RAM 37 where pattern displaying data of address multiplexer 36 designated by horizontal and vertical address counters 23 and 35 is stored are provided. Further, character generator 28 which generates the character code corresponding to individual data stored in RAM 27 and video signal generator circuit 33 which generates video signals according to the code generated by generator 28 and data of RAM 37 are provided. Then, gate circuits 40 and 41 where outputs of counters 23 and 25 are inputted are provided, and outouts of circuits 40 and 41 are supplied to signal generator circuit 33.
