Abstract
PURPOSE: To make it possible to gather status information needed for a system under operation by simple circuit constitution, by storing read-out status information in a region where control word used previously are stored.
CONSTITUTION: If CPU1 gets out of order, CPU0 writes a series of control words into memory unit DMEM1 via information gathering control circuit CTL0 and then actuates information gathering circuit CTL1. Next, CTL1 sends various control signals to CPU1 and also writes status information sent from bus DBUS1 into DMEM1 in sequence. At this time, control words in DMEM1 read out once become unneeded, so that information gathered in the area will be written sequentially. After being informed of the completion of information gathering, CPU0 reads the contents of DMEM1 via CTL0 and collates them with correct data, thereby indicating the fault point.
