Intel i5-4300Y CL8064701558601 Data Sheet

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.

•

The processor supports:
— Two Digital Display (x4 DDI) interfaces that can be configured as DisplayPort*,

HDMI*. The 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

(2.97 GT/s), and HBR2 (5.4 GT/s). When configured as HDMI*, the DDIx4

port can support 2.97 GT/s.

— One dedicated x4 embedded DisplayPort* (eDP*). Built-in displays are only

supported on eDP.

•

The HDMI* interface supports HDMI with 3D, 4K, Deep Color, and x.v.Color. The

DisplayPort* interface supports the VESA DisplayPort* Standard Version 1,

Revision 2.

•

The processor supports High-bandwidth Digital Content Protection (HDCP) for

high-definition content playback over digital interfaces.

•

The processor also integrates dedicated a Mini HD audio controller to drive audio

on integrated digital display interfaces, such as HDMI* and DisplayPort*. The HD

audio controller on the PCH would continue to support down CODECs, and so on.

The processor Mini HD audio controller supports two High-Definition Audio streams

simultaneously on any of the three digital ports.
