A common memory is provided, and communicates with the first data port interface and the second data port interface. A memory management unit is provided, and communicates data from the first data port interface and the second data port interface and an common memory. At least two sets of communication channels are provided, with each of the communication channels communicating data and messaging information between the first data port interface, the second data port interface, and the memory management unit. One set of communication channels provides communication from the first and second data port interfaces to the memory management unit and the other set of communication channels provides communication from the memory management unit to the first and second data port interfaces.
