Signal
Direction
Description
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 insert 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.
control_address
Input
control
slave port Avalon-MM
address
bus. This bus
specifies a word offset into the slave address space.
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_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
readdatavalid
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_waitrequest
Output
control
slave port Avalon-MM
waitrequest
signal.
