Integrated Graphics Subsystem
6.2 Functional Description
The integrated HD Graphics controller (hereafter referred to as an internal graphics controller)
featured in select Intel processors supported by these systems operates off the internal PCIe x16
bus of the processor and, through the Flexible Display Interface (FDI) and the Q57 PCH
component, can drive an external analog multi-scan monitor and/or a DisplayPort-compatible
digital monitor. The integrated graphics controller includes a memory management feature that
allocates portions of system memory for use as the frame buffer and for storing textures and 3D
effects.
Figure 6-1. Integrated Graphics Subsystem, Block diagram
The integrated graphic controller of the Intel i5-661 provides the following features:
■
DirectX DX10 support
■
OpenGL 2.1 support
■
Dynamic video memory allocation, where the amount of memory required by the application
is acquired (or released) by the controller
■
Intelligent memory management allowing tiled memory addressing, deep display buffering,
and dynamic data management
■
Core engine operating up to 900 MHz
■
2560 x 1600 maximum resolution
The integrated graphics controller uses a portion of system memory for instructions, textures,
and frame (display) buffering. At boot time, 32 megabytes of system memory is pre-allocated for
the graphics controller whether using Windows XP, Windows Vista, or Windows 7. Using a
process called Dynamic Video Memory Technology (DVMT), the integrated graphics controller
dynamically allocates display and texture memory amounts according to the needs of the
application running on the system.
