The graphics controller integrated into the 82915G/GV GMCH component includes 2D and 3D 
accelerator engines working with a deeply-pipelined pre-processor.  Hardware cursor and overlay 
generators are also included as well as a legacy VGA processor core. The IGC supports three 
display devices:

The Intel graphics controller uses a portion of system memory for instructions, textures, and 
frame (display) buffering. Using a process called Dynamic Video Memory Technology (DVMT), 
the controller dynamically allocates display and texture memory amounts according to the needs 
of the application running on the system.
