Control Synchronizer Signals

Table 11-2: Control Synchronizer Signals

Signal

Direction

Description

clock

Input

The main system clock. The IP core operates on the rising

edge of this signal.

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.

slave_av_address

Input

slave port Avalon-MM

address

bus. This bus specifies a

word offset into the slave address space.

slave_av_read

Output

slave port Avalon-MM

read

signal. When you assert this

signal, the slave port sends new data at

readdata

.

slave_av_readdata

Output

slave port Avalon-MM

readdata

bus. The IP core uses

these output lines for read transfers.

slave_av_write

Input

slave port Avalon-MM

write

signal. When you assert this

signal, the

gamma_lut

port accepts new data from the

writedata

bus.
