3.8.1 Motion Processing Mode (MODE=1)
When set to operate as a motion co-processor the GF9331 performs edge and ver-
tical motion detection and provides optimal control of the GF9330 filters through the
FIL_SEL[3:0] bus on a pixel by pixel basis.
3.8.2 Disabled Mode (MODE=0)
The GF9331 may also be set to disabled mode of operation. In the disabled mode,
no motion co-processing operations are performed and the FIL_SEL[3:0] output
bus is set to “0000”. In this mode, the input video is still routed to the Y_OUT and
C_OUT pins of the GF9330 (NOTE: Only the active portion of the input video signal
is passed through the device to the GF9330, all other data will be lost from the input
data stream). See
Table 3-6: Modes of Operation
.
The video channel is maintained in bypass mode, however, no processing takes
place. Therefore, field buffers are still in use and the chip must be in a known
programmed state.
3.9 Processing of Input Formats
The GF9331 provides motion processing for the formats identified in
Table 3-7:
