Description
The GF9320 Scaling Processor offers 10 / 8-bit
broadcast quality scaling of video images up to 2048 by
2048 pixels. The GF9320 supports arbitrary display
modes to fit custom applications. Dynamic zoom and
pan effects allow for a variety of aspect ratio conversion

choices while a programmable colour background
generator can be customized to appropriately match the
image content. A fully programmable and flexible output
matrix allows for colour difference over-sampling, gain
and hue controls as well as YCbCr to RGB conversions
to power nearly any display device on the market.
The GF9320 also includes a vertical interpolation filter
to perform stand alone cost-sensitive de-interlacing.
Broadcast quality de-interlacing is offered through a
seamless interface to the GF9330 and GF9331 devices.
Applications
• HDTV Up / Down Converters
• Production Equipment
• Video Walls
• Projection Systems
• Plasma Displays
• LCD TVs
• Home Theatre Systems
• HD DVD Players

3.2 Serial Interface Control
The serial interface download control parameters are grouped into 5 sets as given
in Table 3-1: Serial Interface Download Groups. All parameters may be
downloaded at once or each set can be downloaded individually. This grouping
allows for quick downloading of dynamic parameters (e.g. zoom, pan, gain, etc.)
and only requires that the static parameters be downloaded once. Details of
individual control parameters are provided in Table 3-2: Serial Interface Download
Parameters.

VF[431:0]
a. The GF9320 download parameters are grouped into 5 sets.
b.Each group will be extended with zeros to make an integer number of bytes. In each group the LSB is sent first. So, for instance, the I/
O format parameter group sends 1 zero followed by the PROC_8_BITS bit followed by the OUT_8_BITS bit. A download of all parame-
ters (CMD ID = 0) sends the word:
AP[1175:0] = IO[87:0] | RS[151:0] | OD[159:0] | HF[343:0] | VF[431:0]
where "|" represents concatenation.
As with all other words the LSB of AP[1175:0] is sent first. The CMD_ID word is listed above in binary form from MSB to LSB. As with
all other words the CMD_ID is sent LSB first. For example, a download of the dynamic output parameters (CMD_ID=3) sends 5 zeros fol-
lowed by 2 ones followed by 1 zero followed by OD0 followed by OD1 followed by OD2....OD159.
Note that all CMD_IDs have 5 zeros as the 5 least significant bits so that each download command starts with 5 zeros.
