2D FIR Filter
• Has a delay of a little more than N–1
lines between data input and output in
the case of a N×N 2D FIR Filter.
• Delay caused by line buffering internal
to the IP core.
• Resolution is not configurable at run
time.
• Does not read the control packets
passed through it.
An error condition occurs if an
endofpacket
signal is received too early
or too late for the compile time
configured frame size. In either case, the
2D FIR Filter always creates output
video packets of the configured size.
• If an input video packet has a late
endofpacket
signal, then the extra
data is discarded.
• If an input video packet has an early
endofpacket
signal, then the video
frame is padded with an undefined
combination of the last input pixels.
