![]() The graphics display engine then transmits this pixel data to the display device. The graphics processing engine may include algorithms to process this graphics data block to efficiently determine the internal points of the line and may generate pixel data corresponding to those points so that pixel data representing the complete line can be transmitted to a display device for display. A command may correspond to the line-drawing function, and the data points may correspond to the endpoints of the line. For example, graphics data is generally in RGB format and may include a graphics data block that contains commands and data points. Graphics and video data must be processed differently because each type of data is formatted differently. Some graphics controller chips may also have a video display engine that processes and routes video pixel data to the display device. The graphics controller chip generally contains a graphics processing engine that processes graphics data to produce graphics pixel data, and a graphics display engine that routes graphics pixel data to a display device. G09G5/006- Details of the interface to the display terminalĪ graphics system typically contains a graphics controller card (also called a graphics accelerator or graphics adapter card) having a graphics controller chip that can process both graphics data and video data to produce graphics and video pixel data. ![]()
