Signal
Direction
Description
reset
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.
dout_endofpacket
Output
dout
port Avalon-ST
endofpacket
signal. This signal
marks the end of an Avalon-ST packet.
dout_ready
Input
dout
port Avalon-ST
ready
signal. The downstream
device asserts this signal when it is able to receive data.
dout_startofpacket
Output
dout
port Avalon-ST
startofpacket
signal. This signal
marks the start of an Avalon-ST packet.
dout_valid
Output
dout
port Avalon-ST
valid
signal. The IP core asserts this
signal when it produces data.
Table 16-3: Interlacer Control Interface Signals
These signals are present only if you turn on Pass-through mode.

Direction
Description
control_av_address
Input
control
slave port Avalon-MM
address
bus. This bus
specifies a word offset into the slave address space.
control_av_chipselect
Input
control
slave port Avalon-MM
chipselect
signal. The
control
port ignores all other signals unless you assert
this signal.
control_av_readdata
Output
control
slave port Avalon-MM
readdata
bus. The IP
core uses these output lines for read transfers.
control_av_waitrequest
Output
control
slave port Avalon-MM
waitrequest
signal.
control_av_write
Input
control
slave port Avalon-MM
write
signal. When you
assert this signal, the
control
port accepts new data from
the
writedata
bus.
