Abstract
In various embodiments, an apparatus includes a system-on-chip (SoC) to be disposed in a vehicle having a plurality of cores; a hypervisor arranged to partition the cores into at least two domains, an operational domain and a failover domain; a first operating system (OS) arranged to manage execution of at least a first application in the operational domain to provide a first plurality of functions for the vehicle; a second OS arranged to manage execution of at least a second application in the failover domain to provide a second plurality of functions for the vehicle, on occurrence of a failure of the first application. The second functions comprise a subset of the first functions or less embellished versions of some of the first functions, and the second OS has less capabilities than the first OS. Other embodiments, including storage media and methods, are also described and claimed.
