VEHICLE VIDEO DISPLAY SYSTEM

摘要

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.

主权项

1. A vehicle display system, comprising:
a video camera; a processor; a graphic controller; an image processing module receiving video signals from the video camera and generating first video data in a first format; a memory having a system management mode (SMM) program, wherein the SMM program is configured to, when executed at the processor, instruct the processor to
read the first video data from a first area of the memory;convert the first video data to second video data in a second format; andwrite the second video data to a second area of the memory; a memory controller controlling the memory; and a PCI express switch configured to
forward the first video data in the first format and received from the image processing module to the memory controller for storing in the first area of the memory; andforward the second video data in the second format and retrieved by the memory controller from the second area of the memory to the graphic controller.
