Parameter Value Description
Pattern
• Color bars
• Uniform
background
Select the pattern you want to use for the
background test pattern layer.
Uniform values 0-255; Default = 0 (R/
Y); 128 (G/Cb/B/Cr)
When pattern is uniform background, you
can specify the individual R'G'B' or Y' Cb' Cr'
values depending on the currently selected
color space.

Table 6-3: Alpha Blending Mixer Signals
The table below lists the signals for Alpha Blending Mixer IP core.
Signal Direction Description
reset
Input The IP core asynchronously resets when you assert this
signal. You must deassert this signal synchronously to the
rising edge of the clock signal.
clock
Input The main system clock. The IP core operates on the rising
edge of this signal.
control_av_address
Input
control
slave port Avalon-MM
address
bus. This bus
specifies a word offset into the slave address space.
control_av_chipselect
Input
control
slave port Avalon-MM
chipselect
signal. The
control
port ignores all other signals unless you assert
this signal.
control_av_readdata
Output
control
slave port Avalon-MM
readdata
bus. The IP
core uses these output lines for read transfers.
control_av_write
Input
control
slave port Avalon-MM
write
signal. When you
assert this signal, the
control
port accepts new data from
the
writedata
bus.
control_av_writedata
Input
control
slave port Avalon-MM
writedata
bus. The IP
core uses these input lines for write transfers.
din_N_data
Input
din_N
port Avalon-ST
data
bus. This bus enables the
transfer of pixel data into the IP core.
din_N_endofpacket
Input
din_N
port Avalon-ST
endofpacket
signal. This signal
marks the end of an Avalon-ST packet.
din_N_ready
Output
din_N
port Avalon-ST
ready
signal. The IP core asserts
this signal when it is able to receive data.
din_N_startofpacket
Input
din_N
port Avalon-ST
startofpacket
signal. This signal
marks the start of an Avalon-ST packet.
