Abstract
The present application relates to an apparatus for verifying the integrity of image data comprising mapped texture data is provided and a method of operating thereof. A fragment shader unit is coupled to first and second frame buffers and at least one texture buffer. A first texture sampler unit is configured to output texture mapped fragments to the first frame buffer. A second texture sampler unit is configured to output texture mapped fragments to the second frame buffer. A comparator unit is further configured to compare the image data stored in the first frame buffer and in the second frame buffer. A fault indication signal is issued in case the image data of the first and the second frame buffers mismatch.
