Abstract

1523691 Computer fault detection INTERNATIONAL STANDARD ELECTRIC CORP 28 April 1976 [28 April 1975] 17262/76 Heading G4A Faults in a computer including endless loops in programs at two different priority levels, a halt, and the masking of all interrupts are detected, each detection incrementing an anomaly counter which is reset to zero a time T after being incremented and whose contents are compared with two thresholds. The computer is restarted at a fixed point in the program of least priority when the anomaly count is below the lower threshold, reset and restarted at the fixed point when the count is between the two thresholds, and halted and an alarm signal made when the count exceeds the higher threshold. The anomalies are detected by means of signals which indicate that all interrupts are masked and which persist for a fixed period, by signals which indicate that a program has not passed a given point in its instruction sequence a minimum number of times over a given interval, and by signals which indicate that a given number of clock interrupts, which normally activate the highest priority program, have been ignored.
