Frame Buffer Signals
Table 14-4: Common Signals for Frame Buffer IP Core
The table lists the input and output signals for the Frame Buffer IP core.
Note: The additional clock and reset signals are available when you turn on Use separate clocks for the Avalon-
MM master interfaces.
Signal Direction Description
clock Input The main system clock. The IP core operates on the rising
edge of this signal.
reset Input The IP core asynchronously resets when this signal is high.
You must deassert this signal synchronously to the rising
edge of the clock signal.
din_data Input din port Avalon-ST data bus. This bus enables the
transfer of pixel data into the IP core.
din_endofpacket Input din port Avalon-ST endofpacket signal. This signal
marks the end of an Avalon-ST packet.
din_ready Output din port Avalon-ST ready signal. This signal indicates
when the IP core is ready to receive data.
din_startofpacket Input din port Avalon-ST startofpacket signal. This signal
marks the start of an Avalon-ST packet.
din_valid Input din port Avalon-ST valid signal. This signal identifies the
cycles when the port must enter data.
dout_data Output dout port Avalon-ST data bus. This bus enables the
transfer of pixel data out of the IP core.
dout_endofpacket Output dout port Avalon-ST endofpacket signal. This signal
marks the end of an Avalon-ST packet.
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.
