Abstract

PURPOSE: To make it possible to know easily the state of the other electroic computer system.
CONSTITUTION: Now, a parity error is supposed to occur to main memory unit 12 of electronic computer system 10, causing a fault. As a result, content 17 of one bit at address A1 of shared memory 30 is rewritten from "1" for a normal stage into "0" and electronic computer system 20 is interrupted. When this interruption occurs, the program of this sytem 20 is available for the detection of the fault state of one- bit content 17 by reading out the content at address A1. The fault of system 20 can also be detected at the system 10 side in the same way. Consequently, the state of the component element of the party electronic computer system can be checked only by interrupting it once, and the backup process, etc., of the functions of the party electronic computer system can also be simplified.
