Abstract: It is suitable for the field of computer graphic processing technologies, and provides a method and apparatus for repairing a graphics processing unit (GPU) video memory access based on active error detection. A small video memory is first distributed and used for error detection of video memory access, and a problem of video memory data access abnormality is found in time through a regular active detection. When the video memory data access abnormality is found, a GPU desktop driving module can suspend a display picture update operation, and a GPU kernel driving module first suspends all video memory access, then re-initializes a video memory controller and repairs the video memory access abnormality, and then restores an access of all the modules to a video memory to normal, refreshes a desktop, and restores a graphic desktop to a normal state.
