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 DirectDrawas 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 applicationto send update information directly to the video adapter. DirectDraw can also provide applications such as games direct access to features of particular display devices.
