ABSTRACT:
A multiple channel data communication buffer includes a first side having a plurality of communication ports and a second side having data routing port. A single port transmit memory is coupled between the plurality of communication ports and the data routing port. A transmit arbitration circuit is coupled to the single port transmit memory, which arbitrates access by the plurality of communication ports and the data routing port to the single port transmit memory. A single port receive memory is coupled between the plurality of communication ports and the data routing port. A receive arbitration circuit coupled to the single port receive memory, which arbitrates access by the plurality of communication ports and the data routing port to the single port receive memory.
