A system for verifying the accuracy of an image generated by a display processor and rendering engine is disclosed. The system includes a correlator circuit. The correlator circuit is operable to capture image data produced by a rendering engine from a set of input data and determine a correlation value calculated using a comparison location within the image data and a template. The correlator is further operable to compare the correlation value against a threshold value to determine a match between the comparison location within the image data and the template. The system further includes a checking processor coupled to the correlator circuit. The checking processor is operable to receive data representative of the correlation from the correlator and is further operable to initiate a warning in the event of any error in the data representative of the correlation.
