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.
Signal 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.
