The MegaCore function asynchronously resets when you assert rst. You must
deassert rst synchronously to the rising edge of the is_clk signal.
Clocked video clock. All the video input signals are synchronous to this clock.
control slave port Avalon-MM address bus. Specifies a word offset into the slave
address space.
control slave port Avalon-MM read signal. When you assert this signal, the
control port drives new data onto the read data bus.
control slave port Avalon-MM read data bus. These output lines are used for read
transfers.
control slave port Avalon-MM waitrequest signal.
control slave port Avalon-MM write signal. When you assert this signal,
the control port accepts new data from the writedata bus.
control slave port Avalon-MM writedata bus. These input lines are used
for write transfers.
din port Avalon-ST data bus. This bus enables the transfer of pixel data
into the MegaCore function.
din port Avalon-ST endofpacket signal. This signal marks the end of an
Avalon-ST packet.
din port Avalon-ST ready signal. This signal indicates when the MegaCore
function is ready to receive data.
din port Avalon-ST startofpacket signal. This signal marks the start of
an Avalon-ST packet.
din port Avalon-ST valid signal. This signal identifies the cycles when the
port should input data.
din port Avalon-ST data bus. This bus enables the transfer of pixel data
out of the MegaCore function.
dout port Avalon-ST endofpacket signal. This signal marks the end of an
Avalon-ST packet.
dout port Avalon-ST ready signal. The downstream device asserts this
signal when it is able to receive data.
dout port Avalon-ST startofpacket signal. This signal marks the start of
an Avalon-ST packet.
dout port Avalon-ST valid signal. This signal is asserted when the
MegaCore function outputs data.
