A software
interface standard for transferring video processing from a
PC's CPU to the
video adapter. The
standard was first developed by
Intel and called the
Display Control Interface (DCI) and is now supported by
Microsoft 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.
