1. An electronic circuit card connectable to a host system, the card comprising:

  • a first module including a first controller;

    a second module including a second controller;

    a bus structure connected to both the first controller and the second controller in parallel, through which data and commands are exchangeable between the host system and the first and second modules when the card is connected to the host system; and

    one or more control lines connected between the first controller and the second controller to exchange signals allowing the two modules to interact independently with the host system while functionally appearing as a single unit to the host system,wherein after receiving at least one of data and commands from the host system for processing, the first and second modules are operative to determine, based on communication between the two modules regarding the received at least one of data and commands for processing, which of the first and the second modules should process the received at least one of data and commands.
