menufunctionsin that language.
Display
Brightness and Contrast
-----Adjust the displayed image brightness and contrast
Color
----- Adjust color balance to compensate for ambient conditions
using three submenus:

Custom Color —— Modify the color temperature balance.
Saturation —— Magnify the color intensity.
Keystone
----Adjust image distortion caused by tilting the projector. The
only adjustment direction allowed is to narrow the top width
of the image.
Image
Freeze
----To freeze the display of the current image.

2.4.2 Description
ADC
TheAD9884 is a complete 8-bit Msps monolithic analog
interface optimized for capturing RGB graphics signals from
personal computers and workstations. Its 140 Msps encode
rate capability and full-power analog bandwidth of 500
MHz supports display resolutions of up to 1280*1024
(SXGA) at 75Hz with sufficient input bandwidth to accu
rately acquire and digitize each pixel.
To minimize system cost and power dissipation theAD9884
includes an internal +1.25V reference, PLLto generate a
pixel clock from HSYNC, and programmable gain, offset,
and clamp circuits.
DMD
TheDMD1076 is a spatial light modulator that consists of a
1024(H)*768(V) array of aluminum micro-mechanical
mirrors on a 17-micrometer(um) pitch. Each mirror can be
individually deflected at an angle of +/- 10 degrees about a
hinged diagonal axis. The deflection angle (positive or
negative) of the mirrors can be individually controlled by
changing the memory contents of underlying CMOS ad
dressing circuitry and mirror reset signals. The 1024*768
mirrors are driven in a Block Reset fashion allowing for
either global or phased reset and stepped address voltage
schemes. Effectively, theDMDis an electrical input, optical
output memory device.

Memory
The TE28F400B3T is a nonvolatile, electrically block-
erasable (Flash), programmable read-only memory con
taining 4,193,304 bits organized as 262,144 words by
16 bits or 524,288 words by 18 bits. Smart Voltage
Technology (SVT) provides industry-standard, multi- or
single-voltage, dual-supply operation. Writing or erasing
the device is done with either a 5V or 12V VPP Voltage,
while all operations are performed with a 3.3V or 5V VCC.
It is fabricated with Micron’s advanced CMOS floating-
gate process.
The MT28F400B1 is organized into seven separately
erasable blocks. To ensure that critical firmware is
protected from accidental erasure or overwrite, the
MT28F400B1 features a hardware-protected boot block.
