PURPOSE:To improve the maintenance ability and working efficiency of a data processor by generating an address coincidence signal when a specified address passes by the specified number of times. CONSTITUTION:An address to be stopped and the number of repeating times are set up in registers 2, 10 respectively by prescribed switches. At that time, a counter 11 is set up to ''0''. Subsequently, a microprogram is started by an address search enabling switch. When the value of an address register 1 coincides with that of the register 2, a comparator 3 makes an address coincidence signal 5 significant and the counter 11 counts up. After running a program, the counter 11 counts up every coincidence of registers 1, 2. When the counted value coincides with the value of the register 10 specifying the number of repeating times, the 2nd comparator 12 makes an address coincidence signal 13 significant and a control circuit 6 operates so as to stop the running of the program. |
