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.

Apparatus and method for verifying fragment processing related data in graphics pipeline processing

A cache-coherent multiprocessor system comprising processing units, a shared memory resource accessible by the processing units, the shared memory resource being divided into at least one shared region, at least one first region, and at least one second region, a first cache, a second cache, a coherency unit, and a monitor unit, wherein the monitor unit is adapted to generate an error signal, when the coherency unit affects the at least one first region due to a memory access from the second processing unit and/or when the coherency unit affects the at least one second region due to a memory access from the first processing unit, and a method for detecting failures in a such a cache-coherent multiprocessor system.

Cache-coherent multiprocessor system and a method for detecting failures in a cache-coherent multiprocessor system

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.
