Abstract: A fault detection circuit for detecting faults in a video sequence includes a multiple input signature register (MISR) with a linear feedback shift register (LFSR) that receives pixel data for pixels in a frame region for video frames of a video sequence and receives a read signal to read the pixel data and shift the MISR; a multiple signature storage buffer (MSSB) that stores frame signatures; and a signature comparator that compares current and reference frame signatures to determine if a fault condition exists in the video sequence. The MISR holds a frame signature for the frame region of the video frame while receiving a frame end signal. The MSSB stores a current frame signature held by the MISR after receiving the frame end signal. The MSSB also stores a reference frame signature. A display processing circuit includes the fault detection circuit. An integrated circuit includes the display processing circuit.
