Abstract
PURPOSE: To prevent runaway of a processor by causing a master processor to detect rapidly anomaly of a slave processor.
CONSTITUTION: Master processor 1 sets a start instruction and character information to a print buffer and sends an interrupt signal to slave processor 2 to start the count operation of a time supervisory timer. In case that end information from slave processor 2 is not received after a set time from start of the time supervisory timer, master processor 1 sends a reset signal to slave prcessor 2. When the reset signal is inputted, slave processor 2 becomes the initial state. Master processor 1 decides time-out as the first or the second; and in case of the first time-out, master processor sets the start instruction and character information to the print buffer again and sends the interrupt signal to slave processor 2. When time-out occurs again, slave processor 1 resets slave processor 2.
