Claim:
1. A method for testing an imaging subsystem of a system-on a-chip (SOC), the method comprising: executing imaging subsystem test software instructions, stored in an on-chip memory of the SOC, periodically on a processor of the SOC; receiving reference image data in the imaging subsystem responsive to the executing of the test software instructions; performing image signal processing on the reference image data by the imaging subsystem to generate processed reference image data; and using the processed reference image data by the test software instructions to verify whether or not the imaging subsystem is operating correctly, in which executing imaging subsystem test software instructions periodically includes executing the imaging subsystem test software instructions at fault tolerant time intervals; in which using the processed reference image data includes computing a cyclic redundancy check (CRC) value for the processed reference image data and comparing the computed CRC value to an expected CRC value.
