Systems and methods for fault detection in image sensor processors

An imaging system, comprising:

• first and second image sensors;
• first and second signal processing circuits, wherein the first image sensor is coupled to the first signal processing circuit and the second image sensor is coupled to the second signal processing circuit;
• and
• error detection circuitry that is coupled to the first and second signal processing circuits and that is configured to provide fault detection configuration data to the first and second signal processing circuits, the error detection circuitry comprising a fault detector configured to compare first output test data from the first signal processing circuit with second output test data from the second signal processing circuit to determine whether a fault exists in at least one of the first or second signal processing circuits.

A fault detection circuit configured to detect a fault in a signal processor that processes a plurality of image frames, the fault detection circuit comprising:

• image processing configuration registers configured to store processing circuitry configuration data and configured to provide the processing circuitry configuration data to the signal processor for an image processing mode of operation;
• fault detection configuration registers configured to store fault detection configuration data and configured to provide the fault detection configuration data to the signal processor for a fault detection mode of operation;
• and
• a detection circuit configured to switch between the image processing mode of operation and the fault detection mode of operation based on information for the plurality of image frames.
