摘要： The present application relates to an apparatus for verifying fragment processing related data and a method of operating thereof. The fragment shader unit is coupled to the at least one data buffer. A fragment shader unit of a graphics processing pipeline receives fragment data and records fragment processing related data in the at least one data buffer on processing one or more fragments in accordance with the received fragment data. A comparator unit coupled to the at least one data buffer compares the recorded fragment processing related data in the at least one data buffer to reference data and issues a fault indication signal in case the recorded fragment processing related data and the reference data mismatch.

摘要： The present application relates to an apparatus for verifying the integrity of transformed vertex data and a method of operating thereof. The apparatus comprises a graphics processing pipeline with a vertex shader unit, a buffer and a comparator unit. The vertex shader unit receives a stream of vertex data according to a vertex specification. The vertex shader unit applies a transformation on each of the vertices in the received stream of vertex data to and outputs a stream of transformed vertex data. The buffer is coupled to the vertex shader unit to buffer the transformed vertex data. The comparator is further configured to verify the integrity of at least a subset of the transformed vertex data on the basis of reference data and to issue a fault indication signal in case the verification fails.
