Abstract
An error detection circuit on a semiconductor chip detects whether soft errors have affected flip-flop implemented registers on the semiconductor chip. A signature of these flip-flop implemented registers on the semiconductor chip is periodically captured. The signature allows for the integrity of the flip-flop implemented registers to be constantly monitored. A soft error occurring on any of the flip-flop implemented registers can be immediately detected. In response to the detection, an interrupt is raised to notify software to take action.
