Value
Description
Right offset
0–1080, Default = 10
Specify the x coordinate for the right edge of
the clipping rectangle. 0 is the right edge of
the input area.
Note: The left and right offset values
must be less than or equal to the
input image width.
Bottom offset
0–1080, Default = 10
Specify the y coordinate for the bottom edge
of the clipping rectangle. 0 is the bottom edge
of the input area.
Note: The top and bottom offset values
must be less than or equal to the
input image height.

These signals apply to both Clipper and Clipper II IP cores.
Signal
Direction
Description
•
clock
(Clipper)
•
main_clock
(Clipper II)
Input
The main system clock. The IP core operates on the rising
edge of this signal.
•
reset
(Clipper)
•
main_reset
(Clipper II)
Input
The IP core asynchronously resets when this signal is high.
You must deassert this signal synchronously to the rising
edge of the clock signal.
din_data
Input
din
port Avalon-ST
data
bus. This bus enables the
transfer of pixel data into the IP core.
din_endofpacket
Input
din
port Avalon-ST
endofpacket
signal. This signal
marks the end of an Avalon-ST packet.
din_ready
Output
din
port Avalon-ST
ready
signal. This signal indicates
when the IP core is ready to receive data.
din_startofpacket
Input
din
port Avalon-ST
startofpacket
signal. This signal
marks the start of an Avalon-ST packet.
din_valid
Input
din
port Avalon-ST
valid
signal. This signal identifies the
cycles when the port must enter data.
dout_data
Output
dout
port Avalon-ST
data
bus. This bus enables the
transfer of pixel data out of the IP core.
