1. A method for operating an embedded system covering a plurality of technical applications, the operative functions of which are performed with a respective plurality of application-specific Electronic Control Units (ECUs), wherein each ECU having separate need of resources regarding at least processing and storage subsystems, the method characterized by the steps of:

  • a) operating a preselected one of said ECUs as a “

    donor”

    ECU being provided with predefined storage subsystem resources; and

    b) in case of a breakdown of either a storage subsystem or processing subsystem of a “

    non-donor”

    ECU donating respective predefined resources corresponding to either a broken down storage subsystem or a broken down processing subsystem from said “

    donor”

    ECU to said “

    non-donor”

    ECU wherein either an unbroken down storage subsystem or an unbroken down processing subsystem remains, and wherein the “

    non-donor”

    ECU retains the corresponding unbroken down processing subsystem or the corresponding unbroken down storage subsystem.
