Table 16–3 lists the input and output signals for the Deinterlacer II MegaCore
function.
Table 16–3. Deinterlacer II Signals (Part 1 of 4)
Signal Direction Description
av_st_clock In
The main system clock. The MegaCore function operates
on the rising edge of the
av_st_clock signal.
av_st_reset In
The MegaCore function asynchronously resets when you
assert
av_st_reset . You must deassert this reset signal
synchronously to the rising edge of the
av_st_clock
signal.
av_mm_clock In
Clock for the Avalon-MM interfaces. The interfaces operate
on the rising edge of the
av_mm_clock signal.
(3)
av_mm_reset In
Reset for the Avalon-MM interfaces. The interfaces
asynchronously resets when you assert
av_mm_reset . You
must deassert this reset signal synchronously to the rising
edge of the
av_mm_clock signal.
(3)
din_data In
din port Avalon-ST data bus. This bus enables the
transfer of pixel data into the MegaCore function.
din_valid In
din port Avalon-ST valid signal. This signal identifies the
cycles when the port must input data.
din_startofpacket In
din port Avalon-ST startofpacket signal. This signal
marks the start of an Avalon-ST packet.
din_endofpacket In
din port Avalon-ST endofpacket signal. This signal
marks the end of an Avalon-ST packet.
din_ready Out
din port Avalon-ST ready signal. This signal indicates
when the MegaCore function is ready to receive data.
dout_data Out
dout port Avalon-ST data bus. This bus enables the
transfer of pixel data out of the MegaCore function.
dout_valid Out
dout port Avalon-ST valid signal. The MegaCore function
asserts this signal when it outputs data.
dout_startofpacket Out
dout port Avalon-ST startofpacket signal. This signal
marks the start of an Avalon-ST packet.
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.
control_address In
control slave port Avalon-MM address bus. This bus
specifies a word offset into the slave address space.
(4)
control_write In
control slave port Avalon-MM write signal. When you
assert this signal, the
control port accepts new data from
the
writedata bus.
(4)
control_writedata In
control slave port Avalon-MM writedata bus. These
input lines are used for write transfers.
(4)
control_read In
control slave port Avalon-MM read signal. When you
assert this signal, the
control port outputs new data at
readdata .
