Description

The function of this block is to merge a number of input streams into one output stream. All input interface share the same bandwidth (and therefore width) as the output stream to ensure that maximum throughput can be achieved. The input port buffering will be handled in the AXI Converter block. The arbiter can operate in 1G or 10G mode; this is setup through selecting the data width accordingly.
