The main system clock. The MegaCore function operates on the rising edge of the
clock signal.
The MegaCore function is asynchronously reset when reset is asserted high. The
reset must be de-asserted synchronously with respect to the rising edge of the
clock signal.
din port Avalon-ST data bus. Pixel data is transferred into the MegaCore function
over this bus.
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.
dout port Avalon-ST data bus. Pixel data is transferred out of the MegaCore
function over this bus.
dout port Avalon-ST endofpacket signal. This signal marks the end of an
Avalon-ST packet.
dout port Avalon-ST ready signal. This signal is asserted by the downstream
device 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.
The main system clock. The MegaCore function operates on the rising
edge of the clock signal.
The MegaCore function is asynchronously reset when reset is asserted
high. The reset must be de-asserted synchronously with respect to the
rising edge of the clock signal.
alpha_in_N port Avalon-ST data bus for layer N. Pixel data is
transferred into the MegaCore function over this bus.
