Logical 128-Bit Fixed BLT and 256 Fill Engine

This BLT engine accelerates the GUI of Microsoft Windows* operating systems. The 128-bit BLT engine provides hardware acceleration of block transfers of pixel data for many common Windows operations. The BLT engine can be used for the following:

Move rectangular blocks of data between memory locations

Data alignment

To perform logical operations (raster ops)

The rectangular block of data does not change, as it is transferred between memory locations. The allowable memory transfers are between: cacheable system memory and frame buffer memory, frame buffer memory and frame buffer memory, and within system memory. Data to be transferred can consist of regions of memory, patterns, or solid color fills. A pattern is always 8 x 8 pixels wide and may be 8, 16, or 32 bits per pixel.

The BLT engine expands monochrome data into a color depth of 8, 16, or 32 bits. BLTs can be either opaque or transparent. Opaque transfers move the data specified to the destination. Transparent transfers compare destination color to source color and write according to the mode of transparency selected.

Data is horizontally and vertically aligned at the destination. If the destination for the BLT overlaps with the source memory location, the BLT engine specifies which area in memory to begin the BLT transfer. Hardware is included for all 256 raster operations (source, pattern, and destination) defined by Microsoft*, including transparent BLT.

The BLT engine has instructions to invoke BLT and stretch BLT operations, permitting software to set up instruction buffers and use batch processing. The BLT engine can perform hardware clipping during BLTs.

2.5.2Multi Graphics Controllers Multi-Monitor Support

The processor supports simultaneous use of the Processor Graphics Controller (GT) and a x16 PCI Express* Graphics (PEG) device. The processor supports a maximum of 2 displays connected to the PEG card in parallel with up to 2 displays connected to the processor and PCH.

Note: When supporting Multi Graphics Multi Monitors, "drag and drop" between monitors and the 2x8PEG is not supported.

2.6Digital Display Interface (DDI)

The processor supports:

Three Digital Display (x4 DDI) interfaces that can be configured as DisplayPort*, HDMI*, or DVI. DisplayPort* can be configured to use 1, 2, or 4 lanes depending on the bandwidth requirements and link data rate of RBR (1.62 GT/s), HBR (2.7 GT/s) and HBR2 (5.4 GT/s). When configured as HDMI*, DDIx4 port can support 2.97 GT/s. In addition, Digital Port D ( x4 DDI) interface can also be configured to carry embedded DisplayPort* (eDPx4). Built-in displays are only supported on Digital Port D.

One dedicated Intel FDI Port for legacy VGA support on the PCH.
