MMX
technology
The National Semiconductor
Technology. This technology, an extension to the Intel
architecture, is designed specifically to accelerate multimedia
and imaging applications. It addresses the key characteristics
of applications that must handle large amounts of image, video,
and graphics data.

Display

The integrated display controller can output to a standard VGA
monitor, video monitor, or flat panel
output can support resolutions up to 1280x1024 at 8 bits per
pixel (pseudo-color) and 1024x768 at 16 bits per pixel (hi-color),
with a maximum refresh rate of 75 Hz.
The display controller supports the non-destructive overlay of
graphics onto live video. This function is performed by the
processor's companion chip which receives pixels from the
display controller underlay surface in YUV 4:2:2 format (YUYV
or UYVY) or RGB16 format. In MIL, this means that displays
will be allocated, by default, using the DirectDraw
underlay-surface display architecture.
An NTSC/PAL/RGB video encoder provides output to a video
monitor (such as a TV monitor or VCR). The encoder can
generate NTSC/PAL/RGB output to an 800x600 or 640x480
VGA display. The video encoder can be programmed to output
square pixel resolutions in composite CVBS and Y/C video, or
in RGB video with a separate composite sync. By default, the
encoder operates in underscan mode, providing a visible area
outside of the specified resolution. It is also possible to specify
an overscan encoder display, whereby the visible display area
display is exactly the size of the specified resolution.
In the BIOS Setup program, you can select how much video
memory from the total amount of external memory to set aside
for the display driver. Video memory for display purposes can
be allocated in the following proportions: 1.5, 2.5, 3.5, or 4.5
Mbytes.
