Abstract
A system may include a graphics processing unit (GPU) and a processor. The GPU may include a GPU core and non-error-detection-and-correction (non-EDAC) graphics memory. The graphics memory may contain a data object and a copy of the data object. The processor may be configured to: instruct the GPU to handle the data object and the copy of the data object as textures; and instruct the GPU to execute a texture comparison shader program. The GPU core may be configured to: execute the texture comparison shader program; compare the data object and the copy of the data object; generate comparison results; and output the comparison results as pixels to an off-screen area of a framebuffer. The processor may further be configured to: obtain (a) a hash value of the off-screen area, or (b) the off-screen area; and determine whether the comparison results are at least one expected value.
