Description

The function of this block is to dispatch packets from one input stream to a number of output streams whereby the DPT sub-band channel determines to which output the packets are routed. All input interfaces need to have the same bandwidth (and therefore width) as the output stream to ensure that maximum throughput can be achieved. The arbiter can operate in 1G or 10G mode; this is setup through selecting the data width accordingly.
