Abstract
A method for integrating infrastructure software functions and automotive applications on an automotive electronic control unit (ECU) device. The ECU device includes a hardware architecture and a software architecture, wherein the hardware architecture includes two or more system-on-chips, at least two of which each comprise two or more processing cores and means to communicate with at least one other system-on-chip. The hardware architecture includes memory and means to communicate with other ECU devices. The software architecture includes one, two, or more virtual machine monitors, each of which executes one, two, or more virtual machines. At least two of said virtual machines each execute an operating system, which executes one, two, or more tasks, and the execution of two or more of the tasks uses the time-triggered paradigm. The tasks are tasks of automotive applications from at least two different automotive domains and are tasks of infrastructure software functions.
