<p>PURPOSE:To provide a PC operation state monitoring device for displaying the operation states of a PC on a monitor in the execution order of instructions by simple hardware together with arithmetic results stored in a local memory. CONSTITUTION:The PC operation state monitoring device is provided with an address range setting register 30, a task setting register 31 and a calling source address setting register 32 for storing monitoring conditions inputted through a keyboard, a comparator 35 for comparing whether an instruction to be executed by an instruction executing part 33 corresponds to monitoring conditions stored in these registers 30 to 32 or not, a task number comparator 39, and an address comparator 42. The instruction executing part 33 writes arithmetic results outputted from these comparators 35, 39, 42 in a trace memory 44 and data stored in the memory 44 are stored in a memory 25 in a supporting tool 22 by a control part 24 and displayed on a display part 27 to be a monitor through a display control part 26.</p> |
