Abstract:
A vehicle display system and methods of controlling the same. In certain embodiments, an image processing module receives video signals from a video camera and generates first video data in a first format. A system management mode (SMM) program is stored in a memory. When executed at a processor, the SMM program reads the first video data from a first area of the memory, converts the first video data to second video data in a second format, and writes the second video data to a second area of the memory. A PCI express switch forwards the first video data in the first format to a memory controller for storing in the first area of the memory, and forwards the second video data in the second format from the second area of the memory to the graphic controller.
