din_valid
In
din
port Avalon-ST
valid
signal. This signal identifies the
cycles when the port must input data.
dout_data

port Avalon-ST
data
bus. This bus enables the
transfer of pixel data out of the MegaCore function.
dout_endofpacket
Out
dout
port Avalon-ST
endofpacket
signal. This signal
marks the end of an Avalon-ST packet.
dout_ready
In

port Avalon-ST
startofpacket
signal. This signal
marks the start of an Avalon-ST packet.
dout_valid
Out
