<p>PURPOSE:To make an abnormal state noticeable with a less quantity of hardware by performing state notification that each CPU reaches a prescribed state and, at the same time, whether or not the state notification of each CPU is made to a system controlling area. CONSTITUTION:When a CPU 10 reaches a prescribed state, it is notified to each CPU by driving state notifying means 37-40 provided commonly to each CPU. Therefore, it is understood that any one of the CPUs reaches the prescribed state. On the other hand, display controlling means 36, 41, 24, 26, and 28 detect the CPU which drives the state notifying means 37-40 and causes the detected CPU to be displayed on a system controlling area provided at part of the displaying screen of a display device 21. Accordingly, it can be known that which CPU drives the state notifying means 37-40 and which CPU reaches the prescribed state.</p> |
