Signal

Direction

Description

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

Input

slave port Avalon-MM read signal. When you assert this

signal, the slave port drives new data onto the read data

bus.

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.

slave_av_writedata

Input

slave port Avalon-MM

writedata

bus. The IP core uses

these input lines for write transfers.

slave_av_irq

Output

slave port Avalon-MM

interrupt

signal. Asserted to

indicate that the interrupt registers of the IP core are

updated; and the master must read them to determine

what has occurred.

master_av_clock

Input

master port

clock

signal. The interface operates on the

rising edge of the

clock

signal.

master_av_reset

Input

master port reset signal. The interface asynchronously

resets when this signal is high. You must deassert this

signal synchronously to the rising edge of the clock signal.

master_av_address

Output

master port Avalon-MM

address

bus. This bus specifies a

byte address in the Avalon-MM address space.

master_av_burstcount

Output

master port Avalon-MM

burstcount

signal. This signal

specifies the number of transfers in each burst.

master_av_read

Output

master port Avalon-MM

read

signal. The IP core asserts

this signal to indicate read requests from the master to the

system interconnect fabric.

master_av_readdata

Input

master port Avalon-MM

readdata

bus. These input lines

carry data for read transfers.

master_av_readdatavalid

Input

master port Avalon-MM

readdatavalid

signal. The

system interconnect fabric asserts this signal when the

requested read data has arrived.
