APPARATUS AND METHOD FOR VERIFYING THE ORIGIN OF TEXTURE MAP IN GRAPHICS PIPELINE PROCESSING

摘要

The present application relates to an apparatus for verifying the origin of texture data and a method of operating thereof. The apparatus comprises a frame buffer; at least one texture buffer; a graphics processing pipeline with a fragment shader unit; and a comparator unit. The at least one texture buffer is provided to store texture data and test texture data. The fragment shader unit maps the test texture data retrieved from the texture buffer on a predefined area of the image data stored in the frame buffer. The comparator unit extracts image data values located in the predefined area of the image data stored in the frame buffer; compares the extracted image data with reference data and issues a fault indication signal in case the extracted image data and the reference data mismatch.
