DEVICE OVERVIEW
The GF9330 is a 10-bit high performance VDSP engine that
performs high quality motion adaptive de-interlacing of
interlaced digital video signals. The GF9330 supports
standard definition (SDTV) and high definition (HDTV) signal
formats and clock rates up to 1080p60 with support for
arbitrary display modes.
The GF9330 uses multi-directional adaptive filters for edge
processing, an adaptive vertical motion filter and an
adaptive inter-field motion filter. The GF9330 features detail
enhancement and noise reduction capabilities. The GF9330
also supports 3:2 pull-down, static/freeze-frame detection
and compensation and film rate conversions. The GF9330
may operate as a stand-alone de-interlacer or may be used
with the GF9331 Motion Co-processor to enable higher
quality HD/SD de-interlacing with edge and vertical motion
detection. The two devices can be configured in tandem
such that the GF9331 sends edge detection and vertical
motion filter control information to the GF9330. These
control signals adaptively switch the GF9330's internal
filters on a pixel-by-pixel basis.
The GF9330 integrates all required line delays and
seamlessly interfaces to off chip SDRAMs that form the
required field delays. The device may also operate in
by-pass mode should no processing of the input signal be
desired.
