The wall between computer science and electrical engineering has kept the potential of embedded systems at bay. It is time to build a new scientific foundation with embedded systems design as the cornerstone, which will ensure a systematic and even-handed integration of the two fields. The embedded systems design problem certainly raises technology questions, but more important, it requires building a new scientific foundation that will systematically and even-handedly integrate computation and physicality from the bottom up. Support for this foundation will require enriching computer science paradigms to encompass models and methods traditionally found in electrical engineering.
