Signal

Direction

Description

reset

Input

The IP core asynchronously resets when this signal is high.

You must deassert this signal synchronously to the rising

edge of the clock signal.

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.

Table 16-3: Interlacer Control Interface Signals

These signals are present only if you turn on Pass-through mode.

Direction

Description

control_av_address

Input

control

slave port Avalon-MM

address

bus. This bus

specifies a word offset into the slave address space.

control_av_chipselect

Input

control

slave port Avalon-MM

chipselect

signal. The

control

port ignores all other signals unless you assert

this signal.

control_av_readdata

Output

control

slave port Avalon-MM

readdata

bus. The IP

core uses these output lines for read transfers.

control_av_waitrequest

Output

control

slave port Avalon-MM

waitrequest

signal.

control_av_write

Input

control

slave port Avalon-MM

write

signal. When you

assert this signal, the

control

port accepts new data from

the

writedata

bus.
