Abstract: Multi-port Media Control Channel (MAC) with flexible data-path width. A multi-port receive (RX) MAC block includes multiple RX ports and a plurality of RX circuit blocks comprising an RX MAC pipeline for performing MAC Layer operations on RX data received at the RX ports. The RX circuit blocks are connected with variable-width datapath segments, and the RX MAC block is configured to implement a multi-port arbitration scheme such as a TDM (Time-Division Multiplexed) scheme under which RX data received at a given RX port are forwarded over the variable-width datapath segments using datapath widths associated with that RX port. A multi-port transmit (TX) MAC block implementing a TX MAC pipeline comprising TX circuit blocks connected with variable-width datapath segments is also provided. The RX and TX MAC blocks include CRC modules configured to calculate CRC values on input data received over datapaths having different widths.
