Parameter Value Description
Run-time control On or Off Turn on to enable run-time control for the
cadence detection and reverse pulldown.
• Deinterlacer II : When turned off, the IP
core always performs cadence detection
and reverse pulldown if you turn on the
Cadence detection and reverse pulldown
parameter.
• Broadcast Deinterlacer: When turned off,
the IP core always performs cadence
detection and reverse pulldown and
enables video over film detection.
Cadence detection and reverse
pulldown
On or Off Turn on to enable automatic cadence
detection and reverse pulldown.
The Broadcast Deinterlacer always supports
automatic cadence detection and reverse
pulldown, and video over film detection.
Cadence detection algorithm
• 3:2 detector
• 2:2 detector
• 3:2 & 2:2 detector
Select the cadence detection algorithm you
want to use.
The Broadcast Deinterlacer always performs
both 2:2 and 3:2 per-pixel cadence detection.
Avalon-MM master(s) local
ports width
• 16
• 32
• 64
• 128
• 256
Specify the width of the Avalon-MM ports
used to access external memory.
Use separate clock for the
Avalon-MM master interface(s)
On or Off Turn on to add a separate clock signal for the
Avalon-MM master interface(s) so that they
can run at a different speed to the Avalon-ST
processing. The separation decouples the
memory speed from the speed of the data
path and is sometimes necessary to reach
performance target.
Base address of storage space in
memory
0–0×7FFFFFFF,
Default = 0×00000000
Select a hexadecimal address of the frame
buffers in external memory.
Write master FIFO depth 8–512, Default = 64 Select the FIFO depth of the Avalon-MM
write master interface.
Write master FIFO burst target 2–256, Default = 32 Select the burst target for the Avalon-MM
write master interface.
