A software interface standard for transferring video processing from a PC's CPU to the video adapter. Intel developed the standard first and they called it Display Control Interface (DCI). Microsoft now supports it with the name DirectDraw as a registered trademark. When the CPU is not busy, the Windows Graphics Display Interface (GDI) updates the video display. If the CPU is busy, the DCI driver allows an application to send update information directly to the video adapter. DirectDraw can also provide applications such as games direct access to features of particular display devices.
