1. An apparatus for interprocessor communication, comprising:
a coupling element comprising a first interface to a first microprocessor and a second interface to a second microprocessor, the first interface and the second interface connected together in a galvanically-isolated manner for communication purposes;
a first transducer operably connected to the coupling element and including a first digital-to-analog converter and a first analog-to-digital converter;
a second transducer operably connected to the coupling element and including a second digital-to-analog converter and a second analog-to-digital converter;
a first common ground connection for the first microprocessor, the first transducer, and the first interface of the coupling element; and
a second common ground connection for the second microprocessor, the second transducer, and the second interface of the coupling element,
wherein the first transducer comprises a third interface to the first microprocessor and a fourth interface to the second transducer, and
wherein the second transducer comprises a fifth interface to the second microprocessor and a sixth interface to the first transducer.
