Abstract

PURPOSE:To realize the searching of a fault, by comparing a register which can set an optional value with the instruction or address which is being executed and accordingly noticing an optional command. CONSTITUTION:The contents of a register 7 that can set an optional value plus the instruction or address under execution are selectes 5. Such instruction or address is compared 6 with the contents of the register 7. The output of a comparator 6 is led to a flip-flop (FF) 8, and the output of an address counter 10 is stored in a memory 9 as an address designation signal by the output of the FF8. The writing timing is produced in response to the output of the FF8. In such way, an optional command field of a microprogram register 3 of a device to be monitored is compared with the contents of the register 7. Then the state of operation is stored successively when a coincidence is obtained through the comparison.
