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.
