Methods and Systems for Monitoring the Integrity of a GPU

A system for monitoring integrity of a graphics processing unit (GPU) comprising:

• the GPU;
• a central processing unit (CPU) in communication with the GPU;
• a video memory in communication with the CPU and GPU;
• a system memory in communication with the CPU and GPU;
• a display controller in communication with the video memory, CPU, and GPU;
• and
• a module stored in the system memory including computer instruction code that is executable by at least one of the GPU and CPU and structured to cause at least one of the GPU and CPU to be configured to:
• a) determine a known-good result associate with an operation of the GPU;
• b) generate a test image comprising a test subject using the operation of the GPU, the test subject being associated with the known-good result;
• c) write the test image to the video memory and writing the known-good result to the system memory;
• d) transfer the test subject from the video memory to the system memory;
• e) compare the test subject with the known-good result;
• and
• f) write a flag to system memory indicating failure if comparing the test subject with the known-good result indicates a difference between the test subject and the known-good result.
