The Color Plane Sequencer IP core changes how color plane samples are transmitted across the Avalon-
ST interface.
You can configure the channel order in sequence or in parallel. The Color Plane Sequencer IP core
rearranges the color pattern used to transmit Avalon-ST Video data packets over an Avalon-ST
connection (stream). The Color Plane Sequencer can also split or duplicate a single Avalon-ST Video
stream into two or, conversely, combine two input streams into a single stream.
A color pattern is a matrix that defines a repeating pattern of color samples
Combining Color Patterns
The Color Plane Sequencer IP core combines two Avalon-ST Video streams into a single stream.
In this mode of operation, the IP core combines two input color patterns (one for each input stream) and
arranges to the output stream color pattern in a user-defined way, as long as it contains a valid combina‐
tion of channels in sequence and parallel.
In addition to this combination and arrangement, color planes can also be dropped. Avalon-ST Video
packets other than video data packets can be forwarded to the single output stream with the following
options:
• Packets from input stream 0 (port
din0
) and input stream 1 (port
din1
) forwarded, input stream 0
packets being transmitted last. (The last control packet received is the one an Avalon-ST Video
compliant IP core uses.)
• Packets from input stream 0 forwarded, packets from input stream 1 dropped.
• Packets from input stream 1 forwarded, packets from input stream 0 dropped.
