摘要 |
In an information processing system comprising a diagnosing unit (15) for carrying out, in response to an activation signal (17), a diagnosing operation on a main memory (10), a standard processor (11 or 12), and a system controller (13), a state indication area (20) memorizes a state signal which is produced by a monitoring unit (18) monitoring the diagnosing unit to indicate whether the diagnosing operation is possible and impossible and which, when the diagnosing operation is impossible, makes a diagnosis control unit (19) control retry of the diagnosing operation. Through a request controller (27) operable as a read request supply unit, the state signal is read by a read request signal produced by a signal producing unit (21) to make a judging unit (29) make a delivery control unit (24) allow and inhibit, when the diagnosing operation is possible and impossible, delivery as the activation signal of a communication signal produced by the signal producing unit through a communication controller (25) operable as a communication request supply unit. The state signal is stored in the state indication area by a write request signal produced by the signal producing unit and sent through the request controller which is now operable as a write request controller. |
