Signal Direction Description
control_read Output control slave port Avalon-MM read signal. When you
assert this signal, the control port produces new data at
readdata.
control_readdata Output control slave port Avalon-MM readdata bus. The IP
core uses these output lines for read transfers.
control_readdatavalid Output control slave port Avalon-MM readdata bus. The IP
core asserts this signal when the readdata bus contains
valid data in response to the read signal.
control_write Input control slave port Avalon-MM write signal. When you
assert this signal, the control port accepts new data from
the writedata bus.
control_writedata Input control slave port Avalon-MM writedata bus. The IP
core uses these input lines for write transfers.
control_waitrequest Output control slave port Avalon-MM waitrequest signal.
control_byteenable Output control slave port Avalon-MM byteenable bus. This bus
enables specific byte lane or lanes during transfers.
Each bit in byteenable corresponds to a byte in
writedata and readdata.
During writes, byteenable specifies which bytes are
being written to; the slave ignores other bytes.
During reads, byteenable indicates which bytes the
master is reading. Slaves that simply return readdata
with no side effects are free to ignore byteenable
during reads.
din_N_data Input din_N port Avalon-ST data bus. This bus enables the
transfer of pixel data into the IP core.
din_N_endofpacket Input din_N port Avalon-ST endofpacket signal. This signal
marks the end of an Avalon-ST packet.
din_N_ready Output din_N port Avalon-ST ready signal. The IP core asserts
this signal when it is able to receive data.
din_N_startofpacket Input din_N port Avalon-ST startofpacket signal. This signal
marks the start of an Avalon-ST packet.
din_N_valid Input din_N port Avalon-ST valid signal. This signal identifies
the cycles when the port must input data.
dout_N_data Output dout port Avalon-ST data bus. This bus enables the
transfer of pixel data out of the IP core.
dout_N_endofpacket Output dout_N port Avalon-ST endofpacket signal. This signal
marks the end of an Avalon-ST packet.
