Signal Direction Description
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.
capture_data Output capture port Avalon-ST data bus. This bus enables the
transfer of data out of the IP core.
capture_endofpacket Output capture port Avalon-ST endofpacket signal. This signal
marks the end of an Avalon-ST packet.
capture_empty Output capture port Avalon-ST empty signal.
capture_ready Input capture port Avalon-ST ready signal. The downstream
device asserts this signal when it is able to receive data.
capture_startofpacket Output capture port Avalon-ST startofpacket signal. This
signal marks the start of an Avalon-ST packet.
capture_valid Output capture port Avalon-ST valid signal. The IP core asserts
this signal when it produces data.
control_address Input control slave port Avalon-MM address bus. This bus
specifies a byte address in the Avalon-MM address space.
control_burstcount Input control slave port Avalon-MM burstcount signal. This
signal specifies the number of transfers in each burst.
control_byteenable Input control slave port Avalon-MM byteenable bus.
control_debugaccess Input control slave port Avalon-MM debugaccess signal.
