PW164A ImageProcessor
Flat Panel Display Controller IC
The PW164A ImageProcessor is a highly integrated “system-on-a-chip” that interfaces
analog, digital, and video inputs in virtually any format to a pixel-based display.
Computer and video images from NTSC/PAL to UXGA at virtually any refresh rate can
be resized to fit on a fixed-frequency target display device, with any resolution up to
SXGA. An embedded SDRAM frame buffer and memory controller perform frame-rate
conversion completely on-chip.
With an on-chip microprocessor and reference source code, manufacturers can
develop feature-rich products with rapid time-to-market. Programmable features
include the user interface, custom start-up screen, all automatic imaging features, and
special screen effects.
Pixelworks provides an unrivaled end-to-
end product line of system-on-a-chip inte-
grated circuits (ICs), interface ICs, and
software for the advanced display market.
The Pixelworks product line speeds time-
to-market while setting new benchmarks
in image quality, broad compatibility, ease
of use, and lower overall system cost.
Pixelworks’ innovative system-on-a-chip
ImageProcessors and interface ICs process
and optimize video, computer graphics,
and Web information for display on
flat-panel monitors, projectors, digital
televisions, and other advanced display
products using LCD, plasma, and Digital
Light Processing (DLP) technologies.
