The main system clock. The MegaCore function operates on the rising
edge of the clock signal.
The MegaCore function asynchronously resets when you assert reset.
You must deassert reset synchronously to the rising edge of the clock
signal.
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.
dout 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.
gamma_lut slave port Avalon-MM address. Specifies a word offset into
the slave address space.
gamma_lut slave port Avalon-MM chipselect signal. The gamma_lut
port ignores all other signals unless you assert this signal.
gamma_lut slave port Avalon-MM readdata bus. These output lines are
used for read transfers.
gamma_lut slave port Avalon-MM write signal. When you assert this
signal, the gamma_lut port accepts new data from the writedata bus.
gamma_lut slave port Avalon-MM writedata bus. These input lines are
used for write transfers.
