Table 7–3 lists the input and output signals for the Avalon-ST Video Monitor
MegaCore function.
Table 7–3. Avalon-ST Video Monitor Signals (Part 1 of 2)
Signal Direction Description
clock_clk In
All signals on the monitor are synchronous to this clock. Drive this signal
from the clock which drives the video components that are being monitored.
Do not insert clock crossing between the monitor and the trace system
component. You must drive the trace system’s clock from the same source
which drives this signal.
reset_reset In
This signal only resets the debugging parts of the monitor. It does not affect
the system being monitored. Drive this signal directly from the reset_reset
output of the trace system component.
din_data In din port Avalon-ST data bus.
din_endofpacket In din port Avalon-ST endofpacket signal.
din_ready Out din port Avalon-ST ready signal.
din_startdofpacket In din port Avalon-ST startofpacket signal.
din_valid In din port Avalon-ST valid signal.
dout_data Out
dout port Avalon-ST data bus. This bus enables the transfer of pixel data out
of the MegaCore function.
dout_endofpacket Out
dout port Avalon-ST endofpacket signal. This signal marks the end of an
Avalon-ST packet.
dout_ready In
dout port Avalon-ST ready signal. The downstream device asserts this
signal when it is able to receive data.
dout_startofpacket Out
dout port Avalon-ST startofpacket signal. This signal marks the start of
an Avalon-ST packet.
dout_valid Out
dout port Avalon-ST valid signal. This signal is asserted when the
MegaCore function outputs data.
capture_data Out capture port Avalon-ST data bus.
capture_endofpacket Out capture port Avalon-ST endofpacket signal.
capture_empty Out capture port Avalon-ST empty signal.
capture_ready In capture port Avalon-ST ready signal.
capture_startofpacket Out capture port Avalon-ST startofpacket signal.
capture_valid Out capture port Avalon-ST valid signal.
control_address In control slave port Avalon-MM address bus.
control_burstcount In control slave port Avalon-MM burstcount bus.
control_byteenable In control slave port Avalon-MM byteenable bus.
control_debugaccess In control slave port Avalon-MM debugaccess signal.
control_read In control slave port Avalon-MM read signal.
control_readdata Out control slave port Avalon-MM readdata bus.
control_readdatavalid Out control slave port Avalon-MM readdatavalid signal.
control_write In control slave port Avalon-MM write signal.
